Launch Readiness Review Complete Ahead of 24th SpaceX Resupply Mission

CRS-23 Cargo Dragon
A SpaceX Falcon 9 rocket, topped with the Dragon spacecraft, is seen inside the company’s hangar at NASA’s Kennedy Space Center in Florida on Aug. 24, 2021, prior to being rolled out to the launch pad in preparation for the 23rd commercial resupply services launch. The mission delivered science investigations, supplies, and equipment to the crew aboard the International Space Station.

Joint teams from NASA and SpaceX have completed a launch readiness review ahead of the company’s 24th commercial resupply services mission to the International Space Station for the agency. Liftoff is targeted for Tuesday, Dec. 21, at 5:06 a.m. EST from Launch Complex 39A at the agency’s Kennedy Space Center in Florida, and the live launch broadcast will begin at 4:45 a.m.

SpaceX’s Falcon 9 rocket and Dragon spacecraft have been mated inside the company’s hangar at Launch Complex 39A. Rollout to the launch pad is scheduled for Sunday, Dec. 19, when teams from SpaceX will then raise the Falcon 9 – with Dragon atop – into vertical position in preparation for launch.

Tune in on NASA Television, the NASA app, or the agency’s website at noon Monday, Dec. 20, for the prelaunch news conference from Kennedy’s Press Site with the following participants:

  • Joel Montalbano, manager, NASA’s International Space Station Program
  • Bob Dempsey, acting deputy chief scientist, NASA’s International Space Station Program
  • Sarah Walker, director, Dragon Mission Management, SpaceX
  • Arlena Moses, launch weather officer, Cape Canaveral Space Force Station’s 45th Weather Squadron

SpaceX’s Dragon spacecraft will deliver 6,500 pounds of new science investigations, supplies, and equipment for the international crew. Research includes a protein crystal growth study that could improve how cancer treatment drugs are delivered to patients and a handheld bioprinter that could one day be used to print tissue directly onto wounds for faster healing. Also aboard are experiments from students at several universities as part of the Student Payload Opportunity with Citizen Science (SPOCS) program as well as an investigation from the makers of Tide that examines detergent efficacy in microgravity.
