Planetary Entry Parachute Program (PEPP) aeroshell being uincovered. This aeroshell was used to test parachutes for the NASA Viking Mars program in the 1960s. It was lifted by a balloon to a height of 39 kilometres,where atmospheric conditions are closer to those on Mars. The aeroshell detached from the balloon and fired rockets that propelled it to over Mach 1.5. The parachute deployed and slowed the craft's descent back to Earth. The parachute was used for all future Mars missions. Photographed at Walker Air Force Base,Roswell,New Mexico,USA | |
