Last update of this page: February 3, 2020, 12:08 am ET, to include SSEP Mission 15 to ISS
Night launch of SpaceX-5, January 10, 2015, from Cape Canaveral Air Force Station, FL, adjoining Kennedy Space Center. Aboard the Dragon spacecraft is the SSEP Mission 6 to ISS Yankee Clipper II payload of 17 experiments. Yankee Clipper II payload operations were conducted on the International Space Station for nearly a month before Dragon de-orbit and splashdown in the Pacific off the California coast on February 10, 2015. These experiments were originally lost with the destruction of the Orbital Sciences 3 rocket on October 28, 2014. You can read about the emotional loss of the original Yankee Clipper I experiments and how the student flight teams stepped to the plate and worked to reconstitute the experiments for re-flight. The mantra at SSEP – real spaceflight all the time.
Though the Student Spaceflight Experiments Program (SSEP) is a relatively new STEM education initiative—launched in June 2010—it already has an extensive heritage delivering real on-orbit research experiences for students in grades 5-16.
Since program inception in June 2010, there have been sixteen SSEP flight opportunities—SSEP on STS-134 and STS-135, which were the final flights of Space Shuttles Endeavour and Atlantis; and SSEP Missions 1 through 14 to ISS. A total of 191 communities have participated in the program, reflecting 42 States and the District of Columbia in the U. S., 5 Provinces in Canada, and a community in Brazil. Thus far 58 communities have participated in multiple flight opportunities, reflecting the sustainable nature of the program. For example, with Mission 14, there are 6 communities conducting their 2rd flight, 11 communities conducting their 3rd through 6th flights, and even 2 communities conducting their 7th flight.
Through the first sixteen flight opportunities (through Mission 14), a total of 126,600 grade 5-16 students across 2,496 schools were fully immersed in microgravity experiment design and proposal writing, 25,518 flight experiment proposals were received from student teams, and 314 experiments were selected for flight. A total of 281 experiments have flown through SSEP Mission 13. Another 33 experiments are expected to launch in Summer 2020 as the Mission 14 Apollo payload of experiments on SpaceX-21, launching from Kennedy Space Center, FL. Through Mission 13, 147,400 students across the entire grade preK-16 pipeline were engaged in their communities’ broader STEAM experience, submitting 120,670 Mission Patch designs.

Flight Opportunity Status
SSEP on STS-134 and STS-135, and Missions 1 through 12 to ISS have now been completed. Missions 13 and 14 teams will be reporting on experiment design and results at the 2020 SSEP National Conference in Summer 2020. Operations for Mission 14 started in the 32 participating communities in September 2019, with flight experiments selected mid-December 2019. The 33 Mission 14 flight experiments are now undergoing Flight Safety Review at the Toxicology Office at NASA’s Johnson Space Center in Houston. The Apollo payload of Mission 14 experiments is currently projected to launch in summer 2020 on SpaceX-21.
Mission 15 to ISS was announced on February 3, 2020, with a program start in September 2020. Communities across the U.S., Canada, and more broadly internationally, are invited to participate (see the Mission 15 Announcement of Opportunity).
We invite you to explore the SSEP Launch and On-Orbit Operations History page, which provides a sense of the already rich history of the SSEP Program. Here you will find s list of SSEP missions and payload designations, videos of all SSEP launches, a list of all astronauts that have operated SSEP experiments, and videos of astronauts operating the experiments.
To gauge program impact, you are invited to read the In Our Own Words and the SSEP In the News pages, and explore the Showcase of Community-Created Videos, at the separate SSEP Community Network Hubsite. You are also invited to explore the Full SSEP National Blog Archive, which documents the history of the program since inception.
