The grueling event takes more than 2 hours to complete, requiring competitors to ski a distance longer than a marathon. That’s still, however, less than an eighth of the distance between the two official host cities of the 2026 Winter Olympics and Paralympics—Milan and Cortina d’Ampezzo. With events spread across more than 22,000 square kilometers (8,500 square miles) and eight cities or towns in northern Italy, these are the most geographically dispersed Games in Olympic history. The decentralized design was intentional, allowing planners to control costs and make the event more sustainable by using existing venues rather than constructing several expensive new facilities. More than 90 percent of the venues are existing or temporary facilities, including some refurbished facilities that were used in the 1956 Cortina d’Ampezzo Games. About 2,900 athletes will compete across 116 events over 19 days in 13 venues in what will be the third time Italy has hosted the Games. Several of the key event venues are visible in these satellite images of the two largest host cities—Milan and Verona. The OLI (Operational Land Imager) on Landsat 8 and 9 captured the images on December 8 and 9, 2025, respectively. Olympic festivities will kick off officially on February 6 at San Siro Stadium with performances by pop star Mariah Carey, classical singer Andrea Bocelli, classical instrumentalist Lang Lang, and Italian singer-songwriter Laura Pausini. Built in 1925, San Siro is Italy’s largest stadium and the longtime home of renowned football clubs AC Milan and Inter Milan. December 9, 2025 Milan will mostly host indoor ice events in several other venues around the city. Ice hockey will be spread across two venues, the Milano Santagiulia Ice Hockey Arena and the temporary Milano Rho Ice Hockey Arena. The former, located east of the city in the green and residential Santa Giulia district, is the only new permanent venue constructed for the Games. The latter, in Milano Ice Park, is a temporary transformation of the Fiera Milano Rho exhibition center, a complex of pavilions and a convention center northwest of the city center. Speed skating and figure skating will be in the Milano Ice Skating Arena, an 11,500-person stadium in Assago, a small town just outside of Milan. Outside of the Olympics, the multisport facility is used by a skating school and basketball team and as a venue for tennis, squash, swimming, and several other sports. The February 22 closing ceremonies will take place in Verona, a city of about 250,000 people 150 kilometers east of Milan, in Verona Arena, an ancient Roman amphitheater that was built between the 1st and 3rd centuries. What was once used for animal hunts and gladiator battles will serve as the backdrop for musicians, dancers, and artists in a ceremony that organizers say will honor the spirit of athletics and Italy’s rich cultural heritage. The arena, with a seating capacity of about 22,000, is the third-largest surviving amphitheater in Europe and unusually well-preserved. New events this year will include men’s and women’s ski mountaineering, skeleton mixed team relay, women’s doubles luge, freestyle skiing dual moguls, and women’s large hill ski jumping. The 2026 Olympic mascots are Tina and Milo, a brother-and-sister pair of cheerful, scarf-wearing animated stoats with names inspired by Milan and Cortina. Stoats, also called ermine, are fierce predators in the weasel family known for reportedly mesmerizing prey with energetic dances and for having fur that changes from dark brown in the summer to white in the winter. In Italy, stoats typically live in the mountains above 3,500 meters (11,500 feet). NASA Earth Observatory image by Lauren Dauphin, using Landsat data from the U.S. Geological Survey.

The new drill site will be to the upper left of the existing hole. Curiosity captured the image on Jan. 25, 2026 — Sol 4789, or Martian day 4,789 of the Mars Science Laboratory mission — at 19:20:37 UTC. NASA/JPL-Caltech/MSSS Written by Alex Innanen, Atmospheric Scientist at York University, Toronto Earth planning date: Friday, Jan. 30, 2026 Mars has emerged from its holiday behind the Sun, and we here on Earth have been able to reconnect with Curiosity and get back to work on Mars. Our first planning day last Friday gave Curiosity a full weekend of activities, which wrapped up with getting us ready for our next drill. We checked out a broken white rock in the workspace with APXS, MAHLI, and ChemCam’s laser spectrometer and finished up imaging a sandy area we’ve kept an eye on during conjunction to see if we could catch any wind motion, before taking a small drive to our drill location about 2 meters away (about 6 feet). This location may look familiar — our next drill will be only a few centimeters away from “Nevado Sajama,” which we drilled back in November. The reason we’ve returned here is to do a rare SAM experiment the instrument’s last container of tetramethylammonium hydroxide (or TMAH, for less of a mouthful). TMAH is a chemical that we can mix with our sample from Nevado Sajama to help identify any organic molecules. SAM had only two containers of TMAH (the first of which we used almost six years ago, so we want to be very certain that everything will go well with this experiment. As a result, we did a rehearsal of the handoff of the sample to SAM in Wednesday’s plan, before we drill this weekend. Want to read more posts from the Curiosity team?

As a member of the Crew Operations Office, Erin Edwards and her team manage astronaut candidate training schedules, including field medical exercises, land survival, and underwater operations at NASA’s Neutral Buoyancy Laboratory in Houston. She also develops and tests new training programs to keep crews mission-ready. Along with her role as a crew operations officer, Edwards works in the International Space Station Mission Control Center as a capsule communicator, or capcom, and instructor. As a capcom, she must be fluent in the language of the spacecraft and its operations to clearly relay important information to the crew, especially during dynamic operations. Read on to learn about Edwards’ career with NASA and more! Erin Edwards serves as a capsule communicator, or capcom, in the International Space Station Mission Control Center in Houston.NASA/James Blair Where are you from? Port Moody, British Columbia, Canada. How long have you been working for NASA? I’ve been at NASA for two years. My term here with the military is three years. What was your path to NASA? Super random! I’m a ********* military pilot, previously working in the ********* Special Operations Forces Command as an aircraft commander on the CH-146 Griffon. While we use a lot of space-based assets in aviation, the leap to human spaceflight was unexpected. An opportunity for an officer to work in the astronaut office as a capcom arose a few years ago. As a lifelong space nerd, I figured it would be an amazing opportunity. I applied and was interviewed, and before long, was posted to NASA’s Johnson Space Center as the first ********* non-astronaut to be posted as a capcom and later as an operations officer. How would you describe your job to family or friends that may not be familiar with NASA? My team and I organize the unassigned crew and astronaut candidates’ work lives! As a capcom, I help translate what the engineers are saying in the flight control room for the astronauts aboard the station, and I help with the station activities as call sign Houston. More recently I’ve been assigned as the TH57 Helicopter Project Pilot at AOD to help get that fleet integrated for more lunar-focused Space Flight Readiness Training. What advice would you give to young individuals aspiring to work in the space industry or at NASA? Just go for it! You miss 100% of the shots you don’t take, as Wayne Gretzky said. My background as a military helicopter pilot, Navy diver, and mining engineer may appear to have no relevance to NASA, but that diverse experience has turned out to be useful here as an operations officer for astronaut training. I wouldn’t have known that if I hadn’t thrown my hat in the ring. No matter your technical background, there’s probably a place for it in spaceflight. Your experience has unique ways of benefiting such complex, multifaceted programs like spaceflight—so give it a shot! Is there a space figure you’ve looked up to or someone that inspires you? Spaceflight isn't something we can do on our own, there are many integrated teams comprised of many different types of people all pulling together to make the impossible happen. Erin Edwards Deputy Branch Chief for Crew Operations and Capsule Communicator Honestly, there isn’t a single person, but I think what NASA and my own country’s space program, like others, have committed themselves to as a giant team is what has inspired me over the years. I think I was inspired by that, the mission, and the culture of a united effort of so many to do hard things. What is your favorite NASA memory or the most meaningful project you’ve worked on during your time with NASA? There are two! After only a few months at NASA, I was told by my soon-to-be boss, James ‘Vegas’ Kelly, that I was selected to take over NASA astronaut Jonny Kim’s operations job. This was a huge vote of confidence for me as a new team member from Canada. The second was sending my first transmission to the station as a qualified capcom, which was incredibly cool. I am just a big nerd from a small town in Canada, and never in a million years did I think I would be at NASA at that console, so it was a little mind blowing. Erin Edwards during diving operations at NASA’s Neutral Buoyancy Laboratory in front of the Canadarm2 mock-up.NASA/Tess Caswell What do you love sharing about station? Everyone is playing their part to accomplish important science and experiments that we can't do anywhere else. Erin Edwards Deputy Branch Chief for Crew Operations and Capsule Communicator People always seem surprised at how big the teams are that support the station and how collaborative of an effort it is. It stretches across disciplines, centers, and even countries. That information is critical for solving problems here on Earth. November 2, 2025, marked 25 years of continuous human presence. What does this milestone mean to you? A quarter century of science and partnership aboard the orbital laboratory is a testament to what we can do as a global society when we really want to. To me personally, being able to be here with people who have worked in space or help train the people going next is such a full circle situation. I dreamed of working on a team like this, and it happened 20 years later. That opportunity to fulfill a dream and represent Canada as part of the ISS program means a lot to me! If you could have dinner with any astronaut, past or present, who would it be? I was never able to meet Sally Ride. I think I would have loved to ask her some questions and hear her story in person. Do you have a favorite space-related memory or moment that stands out to you? Dr. Robert Thirsk, a ********* astronaut, spoke to my elementary school in 1996, which he had attended years earlier. I was in sixth grade, and it was a formative interaction. Hearing him talk so passionately about his shuttle mission and life with his team aboard the orbiter was absolutely lifechanging. I didn’t know how I was going to do it, but I decided then that I wanted to work in space. That set my course for life. I’ll likely never get to space, but I got pretty close, and it is really something to pursue a goal like that for so long and have it work out, almost What are some of the key projects you have worked on during your time at NASA? What have been your favorite? Being able to put my operational helicopter background to use in helping to build the helicopter flight program here has been a really cool and unexpected opportunity! I happened to be the right person at the right time with the right skill set to make a difference in that aspect of training. I’m proud of that. Erin Edwards pictured in her role as a Royal ********* Air Force helicopter pilot, where she built skills that she leverages in her work at NASA.********* Armed Forces/Erin Edwards What are your hobbies/things you enjoy doing outside of work? I’m in my forties, but still really like playing contact rugby, which is such a fun sport. Between the tactics, teamwork, bashing into people on the pitch, and a cheeky beer after a game, it’s a great way to spend a weekend. I run a lot and, when I can, climb – any kind of climbing, sport, bouldering, trad, ice climbing. All of it! Day launch or night launch? Night launch! Favorite space movie? Apollo 13. Obviously. NASA Worm or Meatball logo? Meatball! The NASA Meatball logo NASA and its partners have supported humans continuously living and working in space since November 2000. After 25 years of continuous human presence, the space station remains a training and proving ground for the future of commercial space stations, deep space missions, enabling NASA’s Artemis campaign, lunar exploration, and future Mars missions. Every day, we are conducting exciting research aboard our orbiting laboratory that will help us explore farther into space and bring benefits back to people on Earth.

5 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) NASA is leveraging expertise, capabilities, and partnerships across its centers to make Artemis campaign and deep space exploration safer, more reliable, and efficient. At NASA’s Armstrong Flight Research Center in Edwards, California, contributions include technical leadership, unique flight-testing capabilities, and management of a key technology program that advances critical exploration concepts. Artemis II is an upcoming challenging test flight, and the lessons learned will directly prepare NASA to return humans to the surface of the Moon on Artemis III and beyond, as well as send the first astronauts – Americans – to Mars. Gulfstream G-III aircraft collects heat shield data A NASA Gulfstream G-III aircraft lifts off from NASA’s Armstrong Flight Research Center in Edwards, California, on Tuesday, Jan. 20, 2026. Modifications were made to the aircraft to enable it to join three others flying at different altitudes to capture a complete view of the Orion spacecraft’s heat shield during Artemis II reentry. This effort is part of NASA’s Scientifically Calibrated In-Flight Imagery project.NASA/Carla Thomas As preparations continue for the Artemis II launch, NASA Armstrong technicians modified a Gulfstream G-III to collect heat shield data during Orion’s reentry. As part of NASA’s Scientifically Calibrated In-Flight Imagery, the G-III will join other aircraft to capture Orion’s thermal protection data. “Before the Artemis II mission begins, the aircraft will complete a dress rehearsal over the Pacific Ocean to verify the airborne system performance,” said Robert Navarro, NASA Armstrong support aircraft fleet project manager. Technicians at NASA’s Johnson Space Center in Houston installed sensors and special windows for the imagery mission with assistance from NASA Armstrong technicians. Measuring Orion’s reentry heat Inside the Neil Armstrong Operations and Checkout Building high bay at NASA’s Kennedy Space Center in Florida, from left, technicians Kenny Leidner, Diamond ScharSenstine, Russ Novak and Darlene Beville with ASRC Federal, inspect AVOCAT block bonding on the Artemis II heat shield on July 2, 2020. The heat shield is one of the most critical elements of Orion and will protect the capsule and astronauts during reentry through Earth’s atmosphere. Artemis II is the first crewed mission in a series of missions to the Moon and on to Mars. Artemis II will confirm all of the Orion spacecraft’s systems operate as designed in the actual environment of deep space with astronauts aboard. NASA/Isaac Watson NASA Armstrong also assists with the Orion heat shield spectrometer system for Artemis II. The system is designed to collect shock layer radiation data from the heat shield during atmospheric entry, data that will be used to enhance astronaut safety. NASA Armstrong’s expertise in integrating technologies, high reliability flight test instrumentation, and flight operations are a match for some Artemis and deep space projects. “There is nothing that can go to space or come back without going through the atmosphere, so our mission of atmospheric flight research and test is very relevant,” said Brad Flick, NASA Armstrong center director. “We specialize in testing technologies and working through the challenges of flight.” Testing Orion’s launch abort system Under the watchful eyes of technicians, a crane positions the Orion Pad Abort-1 Abort Flight Test module for mass properties testing in the Flight Loads Laboratory at NASA’s Armstrong Flight Research Center in Edwards, California.NASA/Tony Landis Teamwork was on full display at NASA’s Armstrong Flight Research Center in Edwards, California, on Aug. 13, 2009, as engineers and technicians prepared the Pad Abort-1 vehicle – the Orion launch abort system development test article. After assembly and integration, the mock crew capsule was transported to the U.S. Army’s White Sands Missile Range in New Mexico where it successfully completed its test on May 6, 2010.NASA/Tony Landis NASA Armstrong demonstrated that approach when it tested a system to enable Artemis astronauts to escape harm in the event of an emergency on the ground, or in the boost phase of the Orion spacecraft. “We proved the system could get the astronauts to safety,” said Cathy Bahm, project manager for NASA’s Low ***** Flight Demonstrator. Earlier in her career, she played key roles in engineering, integration, and management for Pad Abort-1 and Ascent Abort-2 that validated the Orion spacecraft’s launch abort system. Armstrong integrated and tested the capsule and abort system and operations at the launch abort pad at White Sands Test Facility in New Mexico for the Pad Abort-1 test. “Hopefully we’ll never need it, but knowing I contributed to the safety of future astronauts is a highlight of my career,” Bahm said. “Looking back on it, it was a tremendous accomplishment for the center, the team, and a contribution to the future of space travel.” Flight Opportunities program advances space tech A NASA F/A-18 research aircraft flies near NASA’s Armstrong Flight Research Center in Edwards, California, on Feb. 24, 2025, testing a commercial precision landing technology for future space missions. The Psionic Space Navigation Doppler Lidar (PSNDL) system is installed in a pod located under the right wing of the aircraft.NASA Another contributor to future space travel is the Flight Opportunities program, which matures capabilities needed for NASA missions and commercial applications while strategically investing in the growth of the U.S. commercial spaceflight industry. NASA Armstrong manages the program, which supports flight testing of promising technologies, instruments, and experiments aboard commercial vehicles. Part of the agency’s Space Technology Mission Directorate, the program identifies the best ideas – from industry, academia, and NASA researchers – for flight testing. Flight Opportunities advanced precision landing and optical communications technologies for future lunar missions. “Landing safely in shadowed lunar regions is critical,” said Greg Peters, Flight Opportunities program manager. Another deep space technology Flight Opportunities supported was a vibration isolation platform that helped provide extremely precise pointing for the Deep Space Optical Communications technology demonstration. That instrument used lasers to transmit data between Earth and the Psyche spacecraft from more than 215 million miles away, which could benefit future missions to Mars. NASA Armstrong tested Doppler Lidar system navigation on an F/A-18 to prepare for Moon and Mars missions. Contributions to Artemis, deep space exploration April Torres and Angelo De La Rosa remove wire harnesses for signal input for the Orion Ascent Abort-2 vehicle from electrostatic discharge protective covers at NASA’s Armstrong Flight Research Center in California. NASA/Lauren Hughes NASA Armstrong’s work supporting Artemis and future deep space exploration missions also includes: A NASA F/A-18 based at NASA Armstrong tested an autopilot for the SLS (Space Launch System) that proved sensors would work at the trajectory needed for landing on Mars. NASA Armstrong researchers advanced a Fiber Optic Sensing System that flew in space for the first time on the Low Earth Orbit Flight Test of an Inflatable Decelerator mission. NASA Armstrong researchers developed a cryogenic FOSS, called CryoFOSS, to support future deep space missions. CryoFOSS was used during testing of a system designed to liquefy oxygen – as it would on the Moon or Mars – for use as return-trip fuel. By producing fuel on-site, missions could avoid carrying return fuel from Earth, significantly reducing launch weight and overall mission cost. NASA Armstrong staff were in the control rooms when the Orion spacecraft launch abort system was demonstrated. Before the Ascent Abort-2 tests could advance, NASA Armstrong assisted with component testing and integration work. NASA Armstrong photographers and videographers documented the Orion parachute tests in Yuma, Arizona. Under the Artemis campaign, NASA is returning humans to the Moon for economic benefits, scientific discovery, and to prepare for crewed missions to Mars.

Varda Space Industries/William Godward This Jan. 29, 2026, photo captures the streak the Varda Space Industries W-5 capsule made while returning to Earth. The capsule uses a protective heat shield Varda produced made of cutting-edge material it licensed from NASA. The material, known as C-PICA (Conformal Phenolic Impregnated Carbon Ablator), provides a stronger, less expensive, and more efficient thermal protection coating to capsules, allowing them – and their valuable contents – to return to Earth safely. Developed at NASA’s Ames Research Center in California’s Silicon Valley, C-PICA sets the standard for heat shields, reflecting the decades of expertise that NASA brings to designing, developing, and testing innovative thermal protection materials. This flight test of Varda-produced C-PICA was supported by NASA’s Flight Opportunities program. Image credit: Varda Space Industries/William Godward View the full article

The comet brightened significantly during the December 2025 ******* when SPHEREx made the observations — about two months after the icy body had passed its closest distance to the Sun in late October. The space telescope has the singular capability of seeing the sky in 102 colors, each representing a wavelength of infrared light that provides unique information about galaxies, stars, planet-forming regions, or other cosmic features, including the various gases and dust seen in the coma of 3I/ATLAS. The information gathered by SPHEREx helps scientists better understand what materials 3I/ATLAS contains and how the interstellar object’s pristine ices react to the Sun’s heating as the comet journeys through the solar system. The mission is managed by NASA’s Jet Propulsion Laboratory in Southern California for the agency’s Astrophysics Division within the Science Mission Directorate in Washington. The telescope and the spacecraft bus were built by BAE Systems. The science analysis of the SPHEREx data is being conducted by a team of scientists at 13 institutions across the U.S., and in South Korea and Taiwan, led by Principal Investigator Jamie Bock, based at Caltech with a joint JPL appointment, and by JPL Project Scientist Olivier Dore. Data is processed and archived at IPAC at Caltech in Pasadena, which manages JPL for NASA. The SPHEREx dataset is freely available to scientists and the public.

Landsat Navigation Landsat Home Missions Landsat Next Landsat 9 Landsat 8 Landsat 7 Landsat 6 Landsat 5 Landsat 4 Landsat 3 Landsat 2 Landsat 1 News Latest News People of Landsat Q&As Newsletter Publications Data Overview Cal/Val Open Data Benefits Overview Agriculture & Food Security Disaster Management Ecosystems & Biodiversity Energy Resources Forest Management Human Health Urban Development Water Resources Wildfires Case Studies Outreach Multimedia About An animation shows glaciers in the Karakoram range of Pakistan with monthly ice-velocity measurements overlaid from January through December. On Baltoro Glacier, red areas, indicating high ice velocities, propagate slowly downslope throughout the melting season. NASA/Chad Greene For the first time, scientists have created a comprehensive global dataset revealing how the world’s glaciers speed up and slow down with the seasons. Published in Science in November 2025, this groundbreaking study analyzed over 36 million satellite image pairs—including decades of Landsat data—to track the seasonal “pulse” of every major glacier on Earth. The research, built off the ITS_LIVE ice velocity dataset from NASA’s Jet Propulsion Laboratory (JPL), reveals that seasonal glacier dynamics are becoming more pronounced as our planet warms, with the strongest seasonal variations occurring where annual maximum temperatures exceed freezing. Armed with this global perspective, researchers can continue to tease out patterns in glacial dynamics, identifying how factors including geology and hydrology impact seasonal melting. Alex Gardner, a scientist at NASA JPL and a co-author on this study, explains how combining Landsat and radar data makes this research possible. What makes this research unique from other studies of glacial dynamics? While many past studies have investigated seasonal changes in glacier flow, they have typically focused on single glaciers or specific regions. This localization makes it difficult to extrapolate findings to the rest of the world. This study is the first to characterize seasonal flow changes for all the world’s glaciers. By applying a consistent methodology globally, we were able to isolate the universal relationships that drive seasonal fluctuations in glacier flow. Why did you use Landsat in this work? Did it give you any insight that would have been difficult to get otherwise? We utilized data from Landsat 4/5/7/8/9, as well as ESA’s Sentinel 2 (optical) and Sentinel 1 (radar). Landsat offers an unmatched historical record with dense temporal sampling, particularly following the launch of Landsat 8 in 2013. Three factors make Landsat imagery ideal for detecting “surface displacements” (the subtle pixel shifts used to estimate flow): Near-exact repeat orbits: The satellite returns to the exact same position. Nadir viewing: The instrument looks directly downward. Stable instrument geometry: Distortion is minimized. An animation shows glaciers in southeastern Alaska with monthly ice-velocity measurements overlaid from January through December. Red areas, indicating high ice velocities, begin to expand across Malaspina Glacier in spring. NASA/Chad Greene Why does the ITS_LIVE tool use the Landsat panchromatic band? Which bands from Landsats 4-5 are used? We measure surface displacement using a technique called feature tracking, which tracks the movement of specific surface details between a primary and a secondary image. This approach works best with high-resolution imagery because there are more “features” to track. Therefore, we utilize the 15m panchromatic band. For the older Landsat 4/5 data, we use Band 2 (visible red) because it provides the best contrast over bright glacier surfaces. You used Landsat data in combination with radar data to track ice velocity. What did each of these datasets contribute? Optical and Radar imagery are highly complementary and allow us to reconstruct a complete timeline of glacier flow: Radar (Active Sensor): Can image the surface day or night, regardless of cloud cover, but struggles with feature tracking when the surface is melting (wet snow/ice). Optical (Passive Sensor): Requires sunlight and clear skies, but performs significantly better than radar when the surface is melting. How did you use radar data to validate uncertainties? We characterized uncertainty by analyzing retrieved velocities over stationary surfaces, such as bedrock. If our data showed high variability or movement in areas we know are not moving (like rock), we knew those measurements carried a higher uncertainty. You found that glacier dynamics vary by region and glacier type. Why is it important to understand these global differences? A glacier’s response to external forces—such as meltwater lubricating the bedrock or changes in frontal melting—is highly dependent on local factors (e.g., the material beneath the glacier or the shape of the fjord). This makes it risky to assume that findings from one glacier apply to another. Our study identified general patterns by observing nearly every glacier on Earth. A key finding was the relationship between temperature and flow: Seasonal variability becomes prominent when annual maximum temperatures exceed 0°C. The amplitude of that seasonal cycle increases with every degree of warming above that threshold. Are there plans to incorporate Landsat 9 data into future studies? How would improvements in remote sensing technology (increased temporal revisit, spatial resolution, etc.) impact glacial velocity analyses? We are already ingesting Landsat 9 data into the ITS_LIVE project, which is designed to scale quickly with new sensors. Future sensor improvements offer a trade-off: Increased Spatial Resolution: Allows us to track a higher number of surface features, improving flow estimates. Increased Temporal Frequency: Reduces data gaps caused by surface changes (loss of features), but can potentially increase error rates. This is because displacement is an accumulated signal; features move half the distance in an 8-day pair compared to a 16-day pair, making the movement harder to distinguish from background noise. Are there any research questions you’re interested in that build off this work? This study is just the tip of the iceberg. The dataset is rich with insights on glacier mechanics that are waiting to be uncovered. While we hope to make new discoveries in the coming years, we are equally excited to see what breakthroughs come from the wider scientific community exploring this open data.

Red areas, indicating high ice velocities, expand across the ice cap during the summer months.

During a stretch of frigid weather, ice choked the Hudson River along Manhattan’s western shore. The OLI (Operational Land Imager) on Landsat 8 captured this image of the wintry landscape around midday on January 28. The image is false-color (bands 5-4-3) to distinguish ice (light blue) from open water and snow. Vegetation appears red. Ice is abundant in the Hudson River and visible in smaller amounts in the East River, the Jacqueline Kennedy Onassis Reservoir in Central Park, and waterways in New Jersey. Temperatures in New York City dropped below freezing on January 24 and stayed there for over a week. The high on January 28, the date of the image, was 23 degrees Fahrenheit (minus 5 degrees Celsius). Low temperatures and harsh wind chills gripped much of eastern North America over this ******* amid a surge of Arctic air. Much of the ice in the image likely floated there from farther upriver, where tidal currents are weaker and salinity is lower. These conditions allow water to freeze sooner and at higher temperatures than the faster-flowing, brackish water near the river’s mouth, shown here. A complete freeze of the Hudson around Manhattan is unlikely, experts say, although it did occur back in 1888. Still, the ice buildup was substantial enough for NYC Ferry to suspend services for several days. Iced-up rivers can have other implications, from flooding and infrastructure damage to changes in hydrologic processes that affect water quality and aquatic habitats. Scientists, government agencies, and emergency responders are increasingly turning to remote sensing technologies such as synthetic aperture radar and hyperspectral imaging to track river ice. Improved monitoring can aid in water resource management and mitigate ice’s effects on infrastructure and ecosystems. In addition to the river ice, other signs of winter were visible across New York. A fresh layer of snow coated the landscape following a winter storm, in which a weather station in Central Park recorded nearly 12 inches (30 centimeters) of accumulation on January 25. And the low angle of the midwinter Sun caused the tall buildings in Midtown and Lower Manhattan to cast long shadows. In a neighboring borough on February 2, a shorter shadow was cast—this one by the weather-prognosticating groundhog known as Staten Island Chuck. Folklore holds that the sighting signals six more weeks of winter. When compared with data from NOAA’s National Centers for Environmental Information, the New York rodent was deemed the most accurate of his peer weather “forecasters.” This year, Chuck might be right, at least in the near term: the National Weather Service forecast called for below-average temperatures to persist, with Arctic air returning to the city by the weekend.

NASA/Sam Lott A full moon is seen shining over NASA’s SLS (Space Launch System) and Orion spacecraft, atop the mobile launcher at Launch Pad 39B at NASA’s Kennedy Space Center in Florida in the early hours of February 1, 2026. The agency concluded a wet dress rehearsal for the agency’s Artemis II test flight early Tuesday morning, successfully loading cryogenic propellant into the SLS (Space Launch System) tanks, sending a team out to the launch pad to closeout Orion, and safely draining the rocket. The wet dress rehearsal was a prelaunch test to fuel the rocket, designed to identify any issues and resolve them before attempting a launch. To allow teams to review data and conduct a second wet dress rehearsal, NASA now will target March as the earliest possible launch opportunity for the flight test.

NASA/JPL-Caltech Rapid advances in commercial space, artificial intelligence, and edge computing are transforming what is possible for Earth observation. By pushing more intelligence onboard, missions can move from passively collecting data to actively interpreting and responding to changing surface conditions in near-real time, enabling more targeted observations and dramatically improving the value of data returned to the ground. Within this context, land-focused applications such as regenerative agriculture, sustainable forestry, and broader land resilience efforts stand to benefit enormously from satellites that can adapt what, when, and how they sense based on dynamic environmental signals and algorithmic insight rather than fixed schedules or static acquisition plans. NASA Earth Science Technology Office (ESTO) invites participants to design small satellite (SmallSat) mission concepts that leverage adaptive sensing and onboard processing to enhance regenerative agriculture, forestry, or a similar land resilience objective.​ Participants must work within onboard power, compute, and bandwidth constraints characteristic of SmallSat missions, focusing on how to orchestrate existing land observation algorithms into an efficient, responsive onboard intelligence layer.​ Both hardware-oriented and software-oriented solutions—or combinations of the two—are encouraged. NASA’s primary objective for this challenge is to advance computational and systems approaches for adaptive sensing or onboard processing on SmallSat missions. The goal is not to develop new agricultural or forestry science but rather to improve how SmallSats sense, process, and deliver information to enable these applications.

Though natural breaks in sea ice are called leads, the better term for the human-made fracture seen in these satellite images is a ship channel. In the austral summer, usually in January, an icebreaker rams a path through the fast ice—a type of sea ice that is anchored to the shore—that often covers McMurdo Sound. This annual effort allows cargo ships to reach McMurdo Station, a research base operated by the United States Antarctic Program. The U.S. Coast Guard Cutter Polar Star completed the task in January 2026, arriving after breaking a path through several miles of ice between the Ross Sea and an ice pier at McMurdo. Most of the channel was cut between January 19 and 20. January 2 – January 27, 2026 The animation above, made of images captured by the OLI (Operational Land Imager) on Landsat 8 and 9, offers satellite views of the icebreaker’s work. Images were captured on January 2, 7, 19, 20, 23, 25, and 27. The nearly 120-meter (400-foot) vessel weighs 13,500 tons and has thick steel-plated hulls. With 75,000 shaft horsepower, it’s the world’s most powerful non-nuclear icebreaker. The ship sometimes conducts search-and-rescue missions as well. On January 17, the day marking its 50th year of service, the Polar Star responded to a call from an *********** cruise ship in the Ross Sea hampered by thick, pack ice—a type of sea ice unattached to the shoreline that drifts. After making two close passes to break up the ice and clear a path, the Polar Star escorted the cruise ship 4 nautical miles (7 kilometers) to open water in the Ross Sea, according to the U.S. Coast Guard. Established in 1955, McMurdo Station is the southernmost point on Earth accessible by ship. With a population that swells to 1,200 in the summer, it is the largest research station in Antarctica, hosting a harbor, two airfields, and a helicopter pad. Though once powered by a portable nuclear reactor known as “Nukey ****,” the base now runs on energy from diesel electric generators and a wind farm on Crater Hill. With the ship passage open, McMurdo Station is slated to receive two large deliveries this summer. The Stena Polaris, a tanker, arrived on January 20 with 5 million gallons of diesel fuel. Plantijngracht, a cargo ship, will arrive later with food, supplies, and parts of a new floating pier that will replace the traditional ice pier that military engineers have constructed each winter to give ships somewhere to unload cargo. The U.S. National Science Foundation manages McMurdo Station and much of the science conducted there. NASA has also been involved in several projects at the base over the years. For instance, NASA’s McMurdo Ground Station, a Near Space Network facility, is used to download data from polar-orbiting satellites such as Landsat 9 and SMAP. The agency also flew its Operation Ice Bridge airborne campaign from McMurdo in 2013 and regularly launches research balloons from the station as part of its scientific ballooning program. The Polar Star typically remains at McMurdo through March to keep the ship passage clear and returns to its home port of Seattle in April.

From October 4 to December 6, 2025, the forests in this animation turn from green to orange to brown before being blanketed by white snow. The animation is composed of images from Harmonized Landsat and Sentinel-2 (HLS), a NASA product that combines imagery from the NASA/USGS Landsat 8 and Landsat 9 satellites and the European Space Agency’s Sentinel-2A, 2B, and 2C satellites. The animation showcases the Valley and Ridge province of the Appalachian Mountains, named for its characteristic parallel ridges and valleys. When the supercontinent Pangea formed, the region was compressed, one of the factors producing this folded landscape. The region’s forests, largely deciduous, undergo color change in the fall before shedding their leaves. Certain species change color earlier, while others lose their green pigment later in the season. Because of Virginia’s rich tree diversity—nearly 100 species of deciduous trees are native to the state—the landscape becomes a patchwork of shifting colors. December 6, 2025 Paige Williams, an assistant professor in the School of Life Sciences and Sustainability at Virginia Commonwealth University, identified several notable landscape changes captured in the video. Price Mountain, with nearly entirely deciduous forests, appears bright orange in early November and then fades to brown by mid-month. Northeast of Price Mountain, Blacksburg—home of Virginia Tech—maintains a backdrop of green and gray. Ellet Valley, east of town, stays green until early December, long after surrounding ridgelines fade to brown, due to irrigated agricultural fields, cattle grazing, and golf courses. Evergreens, which retain their foliage year-round, dot the scene with dark green and thrive most on north-facing slopes. Nearly 80 percent of Virginia’s forests are deciduous or a mix of deciduous and pine trees. Deciduous trees lose their leaves every fall in a process called senescence. As days get shorter and temperatures drop, chlorophyll (which gives leaves their green color) begins to break down, revealing other carotenoid plant pigments, usually yellow and orange hues hidden during the spring and summer. Some trees produce new pigments that turn leaves red. Before the leaves fall, the trees absorb as many of their nutrients as possible, recycling them for future growth. In early December, a rare early-season snowstorm visited Virginia. Snow covered the landscape, sliding off steeper slopes and collecting in valleys and flatlands. The National Weather Service reported that by the month’s end, Blacksburg had collected a total of 8.6 inches (22 centimeters) of snow—nearly 4 inches more than the 1991–2020 average for December.

Credit: NASA NASA and Axiom Space have signed an order for the fifth private astronaut mission to the International Space Station, targeted to launch no earlier than January 2027 from the agency’s Kennedy Space Center in Florida. “The award of our fifth private astronaut mission shows that commercial space is not a distant promise, but a present reality,” said NASA Administrator Jared Isaacman. “By expanding access and sharpening competition in low Earth orbit, these missions are building the capabilities NASA will rely on as we move outward to the Moon, Mars, and beyond. We look forward to building upon those capabilities with many private astronaut missions to come.” Axiom Mission 5 is expected to spend up to 14 days aboard the space station. A specific launch date will depend on overall spacecraft traffic at the orbital outpost and other planning considerations. “The International Space Station is a critical platform for enabling commercial industry in low Earth orbit,” said Dana Weigel, manager, International Space Station Program, NASA’s Johnson Space Center in Houston. “Private astronaut missions allow the station to be used as a proving ground for new markets and technologies while enabling science, research, and outreach to contribute to a growing space economy.” Axiom Space will submit four proposed crew members to NASA and its international partners for review. Once approved and confirmed, they will train with NASA, international partners, and the launch provider for their mission. “We are honored NASA awarded Axiom Space its fifth human spaceflight mission,” said Jonathan Cirtain, president and CEO, Axiom Space. “All four previous missions have expanded the global community of space explorers, diversifying scientific investigations in microgravity, and providing significant insight that is benefitting the development of our next-generation space station, Axiom Station. The award underscores Axiom Space’s commitment to redefining access to space, fostering international collaboration, and enabling research opportunities in low Earth orbit for the benefit of all.” Axiom Space will purchase mission services from NASA, including crew consumables, cargo delivery, storage, and other in-orbit resources for daily use. NASA will purchase from Axiom Space the capability to return scientific samples that must be kept cold during transit back to Earth. NASA made the selection from proposals received in response to its March 2025 NASA Research Announcement. The agency is finalizing the mission order for the sixth private astronaut mission to the space station and will share additional information once available. Missions aboard the International Space Station, including private astronaut missions, contribute to advancing scientific knowledge and demonstrating new technologies for future human and robotic exploration flights as part of NASA’s Moon and Mars exploration approach, including lunar missions through NASA’s Artemis campaign.

NASA’s Libera instrument, which is designed to maintain the global data record of Earth’s radiation budget, has successfully completed comprehensive environmental testing. This critical milestone included thermal vacuum tests that simulate the expected space temperature and environments that Libera will experience during its mission. The Libera instrument will fly on Joint Polar Satellite System-4 (JPSS-4), the next satellite in the series, as part of a collaboration between NASA and the National Oceanic and Atmospheric Administration (NOAA). The satellite, targeted for launch in 2027, will be named NOAA-22 once in orbit. The University of Colorado Boulder’s Laboratory for Atmospheric and Space Physics (LASP) developed and built the Libera instrument after it was selected as the first Earth Venture Continuity mission – a NASA program that focuses on innovative, low-cost ways to maintain important Earth science measurements as older missions come to an end. Libera will continue the data record of Earth’s radiation budget, following the series of Clouds and the Earth’s Radiant Energy System (CERES) instruments that flew on the Tropical Rainfall Measuring Mission in 1997 and continued on the Terra, Aqua, Suomi National Polar-orbiting Partnership, and NOAA-20 satellites. Libera is named for the daughter of Ceres in Roman mythology, a nod to its predecessors. NASA has been monitoring the flow of radiant energy in the Earth-atmosphere system for over a half century. This energy drives the motions of the atmosphere and oceans, fuels photosynthesis in plants, forms the protective ozone layer, and sustains all life on Earth. Understanding these flows informs weather forecasting and agricultural planning and prediction among many other applications. It enables an accurate evaluation of Earth system trends for informed strategic planning and risk assessments by the U.S. government and commercial industries. Libera will be the fifth and final instrument delivered to Northrop Grumman in Gilbert, Arizona, for installation onto the JPSS-4 satellite.

3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) The NASA award to SpaceWorks Enterprises will focus on research using the company’s X-60 platform. SpaceWorks While NASA is working with U.S. aviation to explore commercial supersonic technologies, the agency is also looking forward to an even faster era of flight – one of vehicles that can fly hypersonic, or five times the speed of sound. And to further that vision, NASA has issued two awards for studies into vehicle concepts. Some types of vehicles – such as rockets – achieve hypersonic speeds by carrying supplies of oxygen to allow their fuel to burn, instead of using the surrounding air. In contrast, NASA’s Hypersonic Technology Project works to advance “airbreathing,” reusable hypersonic aircraft, which take in air as they fly, allowing for much longer sustained cruising at hypersonic speeds. Given commercial interest in finding applications for airbreathing hypersonic vehicles, the Hypersonic Technology Project is looking to find ways to make testing and development easier. Two contract awards the project made in August are aimed at helping to provide an affordable bridge between hypersonic ground and flight tests. “With these awards, NASA will collaborate with the commercial hypersonics industry to identify new ways to evaluate technologies through flight tests while we address the challenges of reusable, routine, airbreathing, hypersonic flight,” said Dr. Nateri Madavan, director of NASA’s Advanced Air Vehicles Program. The new awards went to SpaceWorks Enterprises, of Atlanta, Georgia, and Stratolaunch of Mojave, California, both of which will support a six-month NASA study exploring how current vehicles could be modified to meet the need for reusable, high-cadence, affordable flight-testing capabilities. SpaceWorks, which received $500,000, will focus on the X-60 platform. Stratolaunch, which received $1.2 million, will focus on its Talon-A platform. Through these awards, NASA wants industry to help define the capabilities needed to achieve flight test requirements. The work will also potentially support a future NASA Making Advancements in Commercial Hypersonics (MACH) project focused on advancing commercial hypersonic vehicles through the development of infrastructure such as cost estimates and schedule requirements for a potential flight vehicle. NASA advances U.S. hypersonic research through the Hypersonic Technology Project under the agency’s Advanced Air Vehicles Program. NASA intends for these projects to help lead the way in enabling revolutionary advancements in fundamental airbreathing hypersonic technologies.

The mission’s “drivers,” or rover planners, use the information to understand the Perseverance’s autonomous decision-making process during its drive by showing why it chose one specific path over other options. This was one of two drives, the first being on Dec. 8, in which generative artificial intelligence provided the route planning. The AI analyzed high-resolution orbital imagery from the HiRISE (High Resolution Imaging Science Experiment) camera aboard NASA’s Mars Reconnaissance Orbiter and terrain-slope data from digital elevation models to identify critical terrain features — bedrock, outcrops, hazardous boulder fields, sand ripples, and the like. From that analysis, it generated a continuous path complete with waypoints, fixed locations where the rover takes up a new set of instructions. The pale blue lines depict the track the rover’s wheels take. The ****** lines snaking out in front of the rover depict the different path options the rover is considering moment to moment. The white terrain Perseverance drives onto in the animation is a height map generated using data the rover collected during the drive. The pale blue circle that appears in front of the rover near the end of the animation is a waypoint.
