I was selected as a PoSSUM (Polar Suborbital Science in the Upper Mesosphere) Scientist-Astronaut candidate and global ambassador for 2021. PoSSUM is a non-profit US astronautics research and education program run by the International Institute for Astronautical Sciences (IIAS).
The program uses next-generation suborbital spacecraft to study the upper atmosphere and its potential role in global climate change. Generally speaking, a suborbital spaceflight is any flight that reaches an altitude higher than 80km, but doesn’t escape Earth’s gravity to make it into orbit.
Anything above 80km is deemed “space” under US legislation, although some nations (including Australia) don’t agree with this and the debate about where “space” begins also called the Kármán line remains ongoing.
