ARPAX Space
From propulsion to advanced avionics
—
ARPAX Space is a French amateur space innovation program focused on the design, development, and
launch of the Gall.X-Star N familly rocket. From water rocket to spaceshot rocket with cool payload, this program encompasses several projects including
water rocket, stratospheric balloon, inhouse avionics development, 10kN range methalox Astreus Engine, hoppers, space shot rocket and bi-liquid
launcher with the ultimate goal of achieving reusability of an amateur bi-liquid rocket. This program with be the occasion to gain experience
and have fun. This a self financed project and a side quest so outcomes may never happen or may not happen often but most important is to have
fun making those project. So stay tuned, who knows where this project will ends up.
