SSEP Mission 22 to ISS: Payload and Program Data
Payload Designation: SSEP24 – Armstrong, named for astronaut Neil A. Armstrong, the first human to walk on the surface of the Moon. Starting with Mission 22 to ISS, SSEP experiment payloads are named for astronauts that have walked on the Moon. (For SSEP Missions 19-21 experiment payloads were named for the surviving orbiter vehicles from the NASA Space Shuttle Program; for SSEP Mission 16-18, experiment payloads were named for NASA’s robotic lunar exploration programs in advance of the Apollo missions; for SSEP Missions 12 to 15, experiment payloads were named for NASA human spaceflight programs; for SSEP Missions 5 to 11, experiment payloads were named for Apollo Command Modules; prior to Mission 5, payloads were named for Apollo Lunar Modules.)
