Lunar Flag Assembly flag, placed about from the centerline of the "Eagle" landing craft, was blown over by the blast of the rocket exhaust during takeoff. Because of this, care was taken by subsequent crews to place the flags at greater distances from the Lunar Module. The landing on Apollo 13 was aborted due to a major spacecraft malfunction encountered before reaching the Moon. The flag carried on that flight was destroyed with the Lunar Module "Aquarius" when it reentered the Earth's atmosphere. A review of photographs taken by the Lunar Reconnaissance Orbiter (LRO) indicates that flags placed during the Apollo 12, Apollo
Apollo Applications Program of the Outer Solar System, and the original "Voyager program" of Mars Lander probes. The Apollo lunar base proposal saw an unmanned Saturn V used to land a shelter based on the Apollo Command/Service Module (CSM) on the Moon. A second Saturn V would carry a three-man crew and a modified CSM and Apollo Lunar Module (LM) to the Moon. The two-man excursion team would have a surface stay time of nearly 200 days and use of an advanced lunar rover and a lunar flier as well as logistics vehicles to construct a larger shelter. The isolation of the CSM
