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
Lunar Roving Vehicle LRV system and its development. LRVs were used for greater surface mobility during the Apollo J-class missions, Apollo 15, Apollo 16, and Apollo 17. The rover was first used on 31 July 1971, during the Apollo 15 mission. This greatly expanded the range of the lunar explorers. Previous teams of astronauts were restricted to short walking distances around the landing site due to the bulky space suit equipment required to sustain life in the lunar environment. The range, however, was operationally restricted to remain within walking distance of the lunar module, in case the rover broke down at any point.
