The FIRST manned suborbital research program

Project PoSSUM is a 501(c)(3) non-profit suborbital research and education program devoted to the study of our upper atmosphere and the role it plays in the understanding of our global climate.

REAL NASA-Supported Research


  • The PoSSUM Imagery Experiment is funded by NASA as the ‘PMC-Turbo’ experiment. PoSSUM members travel to Antarctica in 2017 to launch this balloon experiment.
The Project PoSSUM Space Program

Why be a ‘spaceflight participant’ when you can now do important climate research and learn from the world’s best space scientists and astronaut instructors?

Your flight may even be tax-deductible!

The ONLY Program that trains YOU to be a Scientist-Astronaut!

The PoSSUM Scientist-Astronaut Program and PoSSUM Academy are held at the Embry-Riddle Aeronautical University in Florida.

Graduates receive an ERAU Certificate with Continuing Education Units in ‘Suborbital Mission Operations’.

This is NOT Space Tourism!

PoSSUM Education Programs

PoSSUM Scientist-Astronaut Candidates are trained at Embry-Riddle to fly PoSSUM suborbital noctilucent cloud tomography missions on commercial suborbital spacecraft and further qualify for PoSSUM graduate opportunities:

PoSSUM Research

Aeronomy: PoSSUM conducts high-resolution imagery and tomographic reconstruction of noctilucent cloud structures coupled with temperature and aerosol profiles from research aircraft, Antarctic balloon campaigns, and now commercial manned spacecraft!


Bioastronautics: PoSSUM is the exclusive citizen-science microgravity research partner of Final Frontier Design, holding a NASA Space Act agreement for spacesuit development. We conduct microgravity, high-altitude, and functionality research of Final Frontier spacesuits.


Human Factors: Together with Embry-Riddle, PoSSUM Scientist-Astronaut Candidates are evaluated in many spaceflight analog activities, including mission simulation, analog EVA, and landing/post-landing mission phase analyses. These data help PoSSUM Scientist-Astronauts and team members develop compatible technologies.
