Gregory L Davis is the Principal Technologist at NASA Jet Propulsion Laboratory in Pasadena, CA. He came to speak to us about the how the lab came to be and what it's doing currently. More importantly, he talked about the rovers and other devices that they've sent to Mars and the data they are collecting. He was very excited to announce that there is an upcoming mission to land another Rover in July of this year. For those who are interested, you can watch JPL building this rover live on YOUTUBE.
