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 Lunar Module final three "J-class missions", Apollo 15, 16 and 17, were significantly upgraded to allow for greater landing payload weights and longer lunar surface stay times. The descent engine power was improved by the addition of a extension to the engine bell, and the descent propellant tanks were increased in size. A waste storage tank was added to the descent stage, with plumbing from the ascent stage. These upgrades allowed stay times of up to 75 hours on the Moon. The Lunar Roving Vehicle was carried folded up in Quadrant 1 of the descent stage and deployed by the astronauts after
