SELENE 70 µm (0.0003 in) per character. The sheet was installed under the photovoltaic modules and cooling panels beneath the multi-layered insulation. Major results include: SELENE was part of a renewed global interest in lunar exploration; it was "the largest lunar mission since the Apollo program". It followed Japan's first lunar probe, Hagoromo, launched in 1990. China launched its Chang'e 1 lunar explorer on October 24, 2007, followed by India's 22 October 2008 launch of Chandrayaan-1 and the United States Lunar Reconnaissance Orbiter in June 2009.

Explorer 18 Explorer 18 Explorer 18, also called IMP-A, IMP 1 and S-74, was an American satellite launched as part of Explorers program. Explorer 18 was launched on 27 November 1963 from Cape Canaveral, Florida, United States, with Delta rocket. Explorer 18 was the first satellite of the Interplanetary Monitoring Platform. Explorer 18 was a solar cell and chemical-battery powered spacecraft instrumented for interplanetary and distant magnetospheric studies of energetic particles, cosmic rays, magnetic fields, and plasmas. Initial spacecraft parameters included a local time of apogee of 1020 hours, a spin rate of 22 rpm, and a spin direction of 115° right
