The Google Lunar X Prize has a brief update on LunaTrex, one of the teams competing for the $25 million prize. Team Leader Peter Bitar recently visited Purdue University, where he spoke to the Aero Engineering 450 class that is conducting a simulated GLXP mission. Bitar also gave a 25-minute presentation to about 120 members of something called the Pugwash Group. The presentation was followed by a 90-minute Q&A.
