Europlanet : Simulating the SMART-1 impact
by Doug Ellison in Potsdam
Today is about the Moon - the main conference hall has a series of presentations throughout the day - the first half being mainly about the European orbiter SMART-1. Mark Burchell (who spoke about Stardust yesterday) talked about simulating the impact of SMART-1 into the lunar surface at the end of its mission.
