LEO (ドイツ語:Lunarer Erkundungsorbiter; English: Lunar Exploration Orbiter) was the name of a proposed German mission to the Moon, announced by the German Aerospace Center (DLR) Director Walter Doellinger on March 2, 2007. Because the needed money for the year 2009 was diverted elsewhere, the start of the project was delayed indefinitely.〔(【引用サイトリンク】 "Leo" fliegt nicht zum Mond (Leo does not fly to the moon) )〕 Precise characteristics of the mission were announced in early 2008, and estimated costs were projected to be ca. €350 million (~$514 million) over five years. The mission would involve a lunar orbiter that DLR intended to build and launch in 2012 to map the lunar surface. It would be the first German mission to the Moon and the first European mission to the Moon since SMART-1. Numerous leading German planetologists, among them Gerhard Neukum, Ralf Jaumann and Tilman Spohn, have condemned the indefinite postponement and argue for resuming the LEO-project.〔(Europlanet: ''Erklärung zur Äußerung des Bundesministers für Wirtschaft und Technologie, die vom Deutschen Zentrum für Luft- und Raumfahrt (DLR) vorgeschlagene Mondmission Lunarer Explorations-Orbiter (LEO) zurückzustellen'' )〕 ==Design== The main satellite will weigh about 500 kilograms and is accompanied by a small sub-satellite, which weighs about 150 kilograms. The intended orbital altitude is about 50 km. Planned experiments included measurements of lunar gravitational and magnetic fields. The main satellite would have also carried a microwave radar to probe beneath the lunar surface up to a depth of a few hundred meters. At maximum depth the radar would be able to resolve structures up to two meters. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「LEO (spacecraft)」の詳細全文を読む スポンサード リンク
