SSEP Mission 12 to ISS: Payload and Program Data

Payload Designation: SSEP14 – Mercury (named for NASA’s Project Mercury; starting with Mission 12 to ISS, SSEP experiment payloads are 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: 34, with 28 communities flying 1 experiment, and 3 communities flying 2 experiments
Payload: Suite of Fluids Mixing Enclosure (FME – Mark II) Mini-laboratories
Stowage: NanoRacks Express Rack on ISS

The fourteenth SSEP flight opportunity—SSEP Mission 12 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 March 5, 2017, with accompanying Video Clips describing SSEP by Center Director, Dr. Jeff Goldstein: Clip 1 (NASA), Clip 2 (NASA)

Current Status:
The Mission 12 payload of experiments returned to Earth on August 3, 2018. Mission 12 student flight teams presented at the SSEP National Conferences in June 2018, and July 2019.

The Student Spaceflight Experiments Program (SSEP) is a program of the National Center for Earth and Space Science Education (NCESSE) in the U.S., and the Arthur C. Clarke Institute for Space Education internationally. It is enabled through a strategic partnership with DreamUp PBC and NanoRacks LLC, which are working with NASA under a Space Act Agreement as part of the utilization of the International Space Station as a National Laboratory. SSEP is the first pre-college STEM education program that is both a U.S. national initiative and implemented as an on-orbit commercial space venture.
