The 34th SpaceX commercial resupply mission under contract with NASA is headed to the International Space Station with new scientific experiments after lifting off at 6:05 p.m. EDT Friday on a Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida.

The SpaceX spacecraft, loaded with nearly 6,500 pounds of cargo for the space station’s Expedition 74 crew, is scheduled to autonomously dock at about 7 a.m. Sunday, May 17, to the forward port of the station’s Harmony module.

of sunlight reflected by Earth and the Moon.

These experiments are just a sample of the hundreds of investigations conducted aboard the orbiting laboratory in the areas of biology and biotechnology, physical sciences, and Earth and space science. For more than 25 years, people have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and making research breakthroughs that aren’t possible on Earth. The space station helps NASA understand and overcome the challenges of human spaceflight, expand commercial opportunities in low Earth orbit, and build on the foundation for long-duration missions to the Moon, as part of the Artemis program, and to Mars.

The Dragon spacecraft is scheduled to remain at the station until mid-June, when it will depart and return to Earth with time-sensitive research and cargo, ahead of splashing down off the coast of California.
