Yesterday at work, Steve Squyres came to give a talk to the company's research group, but anyone could attend. So, I quickly made sure my calendar wasn't booked at the time and immediately blocked it off so I could attend. Having just finished his book ( Roving Mars: Spirit, Opportunity, and the Exploration of the Red Planet , ISBN 1401301495) and having followed the EDL phase and subsequent rovings of Spirit and Opportunity, I figured this was a once in a lifetime shot to hear him speak.
For those of you that aren't as NASA-nerdy as I am, Steve Squyres is the PI of the MER team that put Spirit and Opportunity on Mars in January 2004.
Steve talked and showed some truly breathtaking photography. He got asked the same question I posted about back in February 2004 about a mechanism to knock dust of the solar panels, and gave the same answer as I've heard all the other times I've seen it responded to.
Definitely an amazing talk, and I highly recommend reading the book.
