LEO (Lunarer Erkundungsorbiter - engl.: Lunar Exploration Orbiter) is the name of a proposed German mission to the Moon, announced by the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt e.V.) Director Walter Doellinger on March 2, 2007.
Precise characteristics of the mission will be announced in early 2008 and estimated costs are 350 million euros ($513.6 million) over five years, however the mission will involve a lunar orbiter that DLR intends 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.
[edit] 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.
Experiments will measure lunar gravitational and magnetic fields.
The main satellite will carry a microwave radar to probe beneath the lunar surface up to a depth of a few hundred meters. At maximum depth the radar will be able to resolve structures up to two meters.
[edit] Science objectives
The duration of the mission around the Moon will be four years. The entire surface will be charted for the first time. The survey is to be three-dimensional and in colour.
"The probe will examine the moon's surface and provide indications of significant geological formations that could later be of interest for drilling," Doellinger said.
The probe will also investigate the moon's magnetic and gravity fields, look for water and analyse the minerals on its surface. It will use the best camera currently available, the best radar sensors and unique spectrum sensors for measuring the mineral composition.
