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. The United States, European countries (ESA), Russia, Japan, India and China are planning future manned
Explorer 31 Explorer 31 Explorer 31 (also called DME-A) was an American satellite launched as part of the Explorers program of NASA. Explorer 29 was launched on 29 November 1965 from Vandenberg Air Force Base, California, United States, with Thor Agena rocket. Explorer 31 was released along with the Canadian satellite Alouette 2. Explorer 31 was a small ionospheric observatory instrumented to make direct measurements of selected ionospheric parameters at the spacecraft. Since the spacecraft had no tape recorder, data could be observed at the spacecraft only when the spacecraft was in sight of the telemetry station and when commanded on. Experiments
