The halo area of the Apollo 15 landing site, created by the LM's exhaust plume, was observed by a camera aboard the Japanese lunar orbiter SELENE and confirmed by comparative analysis of photographs in May 2008. This corresponds well to photographs taken from the Apollo 15 command module showing a change in surface reflectivity due to the plume ...
Orbital photo of the Hadley-Apennine site; Apollo 15 landing site is marked with a circle. Hadley–Apennine is a region on the near side of Earth's Moon that served as the landing site for the American Apollo 15 mission, the fourth crewed landing on the Moon and the first of the "J-missions", in July 1971.
Apollo 15 lunar surface operations were conducted from July 30 to August 2, 1971, by Apollo 15 Commander David Scott and Apollo Lunar Module Pilot James Irwin, who used the first Lunar Roving Vehicle to make three exploratory trips away from their landing site at the base of the Apennine Mountains, near Hadley Rille.
The light-colored area of blown lunar surface dust created by the lunar module engine blast at the Apollo 15 landing site was photographed and confirmed by comparative analysis of photographs in May 2008. They correspond well to photographs taken from the Apollo 15 Command/Service Module showing a change in surface reflectivity due to the plume ...
Apollo 15 was the first of the Apollo program's "J" Missions [2] which used an enhanced Lunar Module that was capable of supporting a 3-day stay on the lunar surface *and* the delivery of the Lunar Roving Vehicle (LRV or "Rover") to the surface to allow the crew to extend the range of their exploration and to provide remote TV coverage.
They had been found at the Apollo 12 and Apollo 14 landing sites but not at the Apollo 11 site, which was about 1,000 km to the east of the Apollo 14 site. At the time of Apollo 15, scientists were interested in whether KREEP rocks were found all over the Moon or just in the region around 12 and 14.
Mons Hadley Delta and St. George crater taken by Dave Scott during stand-up EVA of the Apollo 15 expedition on July 30, 1971. To the north of this mountain is a valley that served as the landing site for the Apollo 15 expedition. To the northeast of this same valley is the slightly larger Mons Hadley peak with a height of about 4.6 km.
The descent orbit insertion (DOI) burn was performed behind the Moon on the second orbit. This burn placed them into a 58.8 by 9.5 nautical mile (108.9 by 17.6 km) orbit, with the low point over Hadley Rille landing site. On Apollo 11 and Apollo 12 this burn was done by the
