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 50 Explorer 50 Explorer 50, also known as IMP-J or IMP-8, was a NASA satellite launched to study the magnetosphere. It was the eighth and last in a series of the Interplanetary Monitoring Platform. Explorer 50 was launched on 23 October 1973 at 02:26:03 UTC, by a Delta 1604 rocket from Cape Canaveral AFS, Florida. The spacecraft functioned nominally until 7 October 2006. The satellite orbited the Earth once every 12 days, at an inclination of 28.6 degrees. Its perigee was 22 earth radii and apogee was 45 earth radii. Explorer 50 was a drum-shaped spacecraft, across and height, with propulsion
