Mars Gashopper Airplane Mars Ship One in Flight

Pioneer Astronautics has demonstrated a new technology for flying around Mars.

The new flight system is called a gashopper. The vehicle system works by acquiring CO2 from the Martian atmosphere with a pump (Mars atmosphere is 95% CO2) , storing it in liquid form, then sending it through a preheated pellet bed to turn it into hot rocket exhaust to produce thrust for a flight vehicle.
