This project is part of a research effort by the T*AFSM in collaboration with NASA Johnson Space Center. The goal in this project is to simulate the aerodynamics of both the Crew Return Vehicle of the International Space Station and the ram-air parachute to be used for the gliding and soft landing of the CRV.
