Meet Breea Govenar, a biologist at Penn State University, as she speaks to us from aboard a research vessel from Wood's Hole Oceanographic Institute. She'll discuss life near deep-sea thermal vents in the Pacific Ocean. The Webcast also includes Dr. Alissa Arp, a biologist from San Francisco State University studying the tube worms that live around these very hot marine spots. In preparation for the 2004 landing of the Mars Exploration Rovers, NASA engineers and scientists tested their remote operation procedures using a rover called FIDO (field integrated design & operations rover). Our remote team traveled to the desert test site to see what they learned in the desert and what they hoped to learn on Mars.
