This Cosmoquest Science Hangout featured Ravi Prakash, Curiosity Entry, Descent, and Landing Systems Engineer. He explained how Curiosity will land on Mars, and why they've changed things since Spirit and Opportunity landed.
There was good news and bad news in this morning's press briefing about Curiosity rover's upcoming landing on Mars, just eight weeks from now. First, the good news: the landing ellipse has shrunk. The bad news: there's a contamination problem with the drill, and the Odyssey orbiter is in safe mode.
