Röntgen (crater)
Röntgen is a relatively large Lunar craters, lunar impact crater that lies along the northwestern limb of the Moon. Its northwestern outer rim is partly overlain by the crater Nernst (crater), Nernst. Both Nernst and Röntgen overlie the eastern rim of the much larger walled plain Lorentz (crater), Lorentz. The smaller crater Aston (crater), Aston is separated from the eastern edge of Röntgen by only a few kilometers of terrain. To the south-southeast is Voskresenskiy (crater), Voskresenskiy. The outer rim of Röntgen has been heavily eroded by subsequent impacts, and it now forms an uneven, jumbled ring of ridges in the surface. There is a relatively fresh, cup-shaped crater along the common rim between Röntgen and Nernst. The interior floor of Röntgen is nearly level, with only a few patches of uneven terrain near the edges and a low ridge near the midpoint. The surface of the floor is marked by a few small and several tiny craterlets. Prior to formal naming by the Internat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lunar Reconnaissance Orbiter
The Lunar Reconnaissance Orbiter (LRO) is a NASA robotic spacecraft currently orbiting the Moon in an eccentric Polar orbit, polar mapping orbit. Data collected by LRO have been described as essential for planning NASA's future human and robotic missions to the Moon. Its detailed mapping program is identifying safe landing sites, locating potential resources on the Moon, characterizing the radiation environment, and demonstrating new technologies. Launched on June 18, 2009, in conjunction with the LCROSS, Lunar Crater Observation and Sensing Satellite (LCROSS), as the vanguard of NASA's Lunar Precursor Robotic Program, LRO was the first United States mission to the Moon in over ten years. LRO and LCROSS were launched as part of the United States's Vision for Space Exploration program. The probe has made a 3-D map of the Moon's surface at 100-meter resolution and 98.2% coverage (excluding polar areas in deep shadow), including 0.5-meter resolution images of Apollo landing sites. ...
