The Pegasus crew began installing the pedestals July 10. The barge, which previously was used to ferry space shuttle external tanks, was modified and refurbished to compensate for the much larger and heavier core stage for the SLS rocket. Measuring 212 feet in length and 27.6 feet in diameter, the core stage is the largest rocket stage NASA has ever built and the longest item ever shipped by a NASA barge.

Pegasus now measures 310 feet in length and 50 feet in width, with three 200-kilowatt generators on board for power. Tugboats and towing vessels moved the barge and core stage from Michoud to Kennedy, where the core stage will be integrated with other elements of the rocket and prepared for launch. Pegasus is maintained at NASA Michoud.

Marshall Engineers Unveil Versatile, Low-cost Hybrid Engine Testbed

By Rick Smith

In June, engineers at NASA’s Marshall Space Flight Center unveiled an innovative, 11-inch hybrid rocket motor testbed.

The new hybrid testbed, which features variable flow capability and a 20-second continuous ***** duration, is designed to provide a low-cost, quick-turnaround solution for conducting hot-***** tests of advanced nozzles and other rocket engine hardware, composite materials, and propellants.

Solid rocket propulsion ******** a competitive, reliable technology for various compact and heavy-lift rockets as well as in-space missions, offering low propulsion element mass, high energy density, resilience in extreme environments, and reliable performance.

“It’s time consuming and costly to put a new solid rocket motor through its paces – identifying how materials perform in extreme temperatures and under severe structural and dynamic loads,” said Benjamin Davis, branch chief of the Solid Propulsion and Pyrotechnic Devices Branch of Marshall’s Engineering Directorate. “In today’s fast-paced, competitive environment, we wanted to find a way to condense that schedule. The hybrid testbed offers an exciting, low-cost solution.”

Initiated in 2020, the project stemmed from NASA’s work to develop

, additively manufactured – or 3D-printed – nozzles, and other components with proven benefits across the spacefaring spectrum, from rockets to planetary landers.

After analyzing future industry requirements, and with feedback from NASA’s aerospace partners, the Marshall team recognized that their existing 24-inch rocket motor testbed – a subscale version of the Space Launch System booster – could prove too costly for small startups. Additionally, conventional, six-inch test motors limited flexible configuration and required multiple tests to achieve all customer goals. The team realized what industry needed most was an efficient, versatile third option.

“The 11-inch hybrid motor testbed offers the instrumentation, configurability, and cost-efficiency our government, industry, and academic partners need,” said Chloe Bower, subscale solid rocket motor manufacturing lead at Marshall. “It can accomplish multiple test objectives simultaneously – including different nozzle configurations, new instrumentation or internal insulation, and various propellants or flight environments.”

“That quicker pace can reduce test time from months to weeks or days,” said Precious Mitchell, solid propulsion design lead for the project.

Another feature of great interest is the on/off switch. “That’s one of the big advantages to a hybrid testbed,” Mitchell said. “With a solid propulsion system, once it’s ignited, it will ***** until the fuel is spent. But because there’s no oxidizer in hybrid fuel, we can simply turn it off at any point if we see anomalies or need to fine-tune a test element, yielding more accurate test results that precisely meet customer needs.”

The team expects to deliver to NASA leadership final test data later this summer. For now, Davis congratulates the Marshall propulsion designers, analysts, chemists, materials engineers, safety personnel, and test engineers who collaborated on the new testbed.

“We’re not just supporting the aerospace industry in broad terms,” he said. “We’re also giving young NASA engineers a chance to get their hands ****** in a practical test environment solving problems. This work helps educate new generations who will carry on NASA’s mission in the decades to come.”

For nearly 65 years, Marshall teams have led development of the U.S. space program’s most powerful rocket engines and spacecraft, from the Apollo-era Saturn V rocket and the space shuttle to today’s cutting-edge propulsion systems, including NASA’s newest rocket, the Space Launch System. NASA technology testbeds designed and built by Marshall engineers and their partners have shaped the reliable technologies of spaceflight and continue to enable discovery, testing, and certification of advanced rocket engine materials and manufacturing techniques.

Andrew Schnell, acting manager of the Chandra X-ray Observatory at NASA’s Marshall Space Flight Center, honored 25 years of the project’s mission success at National Space Club – Huntsville’s breakfast event on July 16.

Schnell provided insight into Chandra’s history – sharing photos and stories from the project’s initial development, launch, first light images, and some of the most iconic images captured by the telescope to date.

Chandra launched on STS-93 Shuttle Columbia July 23, 1999. Originally designed as a five-year mission, the telescope’s prolonged success is a testament to the agency’s engineering capabilities.

“One of the things that excites me about working with Chandra is that are we not only changing our understanding of the universe today, but the data we collect now may help answer questions astrophysicists haven’t even asked yet.” Schnell said. “One day, an astrophysicist – maybe one that hasn’t been born yet – will have a theory, and our data will be there to help them test that theory.” (Photo Credit: Face to Face Marketing)

Take a Summer Cosmic Road Trip with NASA’s Chandra and Webb

It’s time to take a cosmic road trip using light as the highway and visit four stunning destinations across space. The vehicles for this space get-away are NASA’s Chandra X-ray Observatory and James Webb Space Telescope.

The first stop on this tour is the closest, Rho Ophiuchi, at a distance of about 390 light-years from Earth. Rho Ophiuchi is a cloud complex filled with gas and stars of different sizes and ages. Being one of the closest star-forming regions, Rho Ophiuchi is a great place for astronomers to study stars. In this image, X-rays from Chandra are purple revealing infant stars that violently flare and produce X-rays. Infrared data from Webb are red, yellow, cyan, light blue and darker blue and provide views of the spectacular regions of gas and dust.

The next destination is the Orion Nebula. Still located in the Milky Way galaxy, this region is a little bit farther from our home planet at about 1,500 light-years away. If you look just below the middle of the three stars that make up the “belt” in the constellation of Orion, you may be able to see this nebula through a small telescope. With Chandra and Webb, however, we get to see so much more. Chandra reveals young stars that glow brightly in X-rays, ******** in red, green, and blue, while Webb shows the gas and dust in darker red that will help build the next generation of stars here.

It’s time to leave our galaxy and visit another. Like the Milky Way, NGC 3627 is a spiral galaxy that we see at a slight angle. NGC 3627 is known as a “barred” spiral galaxy because of the rectangular shape of its central region. From our vantage point, we can also see two distinct spiral arms that appear as arcs. X-rays from Chandra in purple show evidence for a supermassive ****** ***** in its center while Webb finds the dust, gas, and stars throughout the galaxy in red, green, and blue. This image also contains optical data from the Hubble Space Telescope in red, green, and blue.

Our final landing place on this trip is the farthest and the biggest. MACS J0416 is a galaxy cluster, which are among the largest objects in the Universe held together by gravity. Galaxy clusters like this can contain hundreds or even thousands of individual galaxies all immersed in massive amounts of superheated gas that Chandra can detect. In this view, Chandra’s X-rays in purple show this reservoir of hot gas while Hubble and Webb pick up the individual galaxies in red, green, and blue.
