SSEP Mission 18 to ISS: Payload and Program Data
Payload Designation: SSEP20 – Surveyor, named for NASA’s Surveyor Program, which soft-landed 7 spacecraft on the lunar surface in advance of the Apollo Moon landings. Starting with Mission 16 to ISS, SSEP experiment payloads are 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.)
Number of Student Team Flight Experiments: 39
37 communities are participating in SSEP Mission 18 to ISS
39 flight experiments were selected, with 35 communities flying 1 experiment and 2 communities flying 2 experiments
Payload: Suite of Fluids Mixing Enclosure (FME – Mark II) Mini-laboratories
Stowage: Nanoracks Express Rack in the Japanese Experiment Module (JEM; also nicknamed Kibo) on ISS
History:
The 20th SSEP flight opportunity—SSEP Mission 18 to the International Space Station—was announced by the National Center for Earth and Space Science Education (NCESSE) and the Arthur C. Clarke Institute for Space Education on February 2, 2023, with accompanying Video Clips describing SSEP by Center Director, Dr. Jeff Goldstein: Clip 1 (NASA), Clip 2 (NASA)
Current Status:
Flight experiments are in hand at Nanoracks in Houston in preparation for launch.
