Capricorn One

Capricorn One, the first manned mission to Mars, is on the launch pad and the public is unaware that the spacecraft is empty. At the base, the astronauts are informed by NASA official Kelloway that a faulty life-support system would have killed the astronauts during the flight, and they must help counterfeit the television footage. The astronauts remain in captivity and are filmed landing on Mars within a studio located at the base. Upon returning to Earth, the empty spacecraft burns up due to a faulty heat shield during re-entry.
