Lunar Lander Challenge competitor MicroSpace has filed a letter of intent to go for the Google Lunar X PRIZE. From the news release:
Our "Human Lunar Lander", with its split tank grouping, makes it easy to load a "Rover" unit, and we intend to display this as a full scale system at the 2007 "X PRIZE Cup" event. We also have in operation, and will display, an innovative Lunar Rover for this use.
Micro-Space continues to be a participant in the "Northrop Grumman Lunar Lander Competition". Although we have made considerable progress with our Lander’s subsystems, we have not been able to focus as intensely as we had hoped on this project and we will not receive a FAA Launch License in 2007.
