A SpaceX Falcon 9 rocket lifts off from Launch Complex 39A at NASA’s Kennedy Space Center in Florida at 3:14 a.m. on Aug. 29, 2021, carrying the Dragon spacecraft on its journey to the International Space Station for NASA and SpaceX’s 23rd commercial resupply services mission. Dragon delivered new science investigations, supplies, and equipment to the crew aboard the orbiting laboratory.

The SpaceX Falcon 9 rocket carrying the Dragon cargo spacecraft lifts off from Launch Complex 39A at NASA’s Kennedy Space Center in Florida on Nov. 26, 2022, on the company’s 26th commercial resupply services mission for the agency to the International Space Station. Liftoff was at 2:20 p.m. EST. Dragon will deliver more than 7,700 pounds of cargo, including a variety of NASA investigations, supplies, and equipment to the crew aboard the space station, including the next pair of ISS Roll Out Solar Arrays (iROSAs). The spacecraft is expected to spend about a month attached to the orbiting outpost before it returns to Earth with research and return cargo, splashing down off the coast of Florida.
