2007 Lunar Lander Challenge registration opens

The X Prize has a news release on the opening of registration for the 2007 Lunar Lander Challenge competion. Spaceref has a post on the release as does the X Prize Foundation. There are also rule changes for this year allowing repairs to the vehicle after the first hop ... as long as the repair materials are brought on the first hop, and not counted as payload. Northrop Grumman, builder (in an earlier form) of the Apollo Lunar Module, is the title sponsor for the event again. RLV News also informs us about this news and is tracking the competitors.
