Origins: Astrobiology:  Life at High Temperatures (Webcast)
Running Time:
00:37:45
Jonathan Trent, Astrobiologist, NASA Ames Research Center studies "thermophiles," heat-loving microbes inhabiting places once thought too hostile for life, but analogous to environments that might be found on other planets. He discovered that some of these microbes make a protein that appears to stabilize their cell membranes (and may have applications for nanotechnology).

Light and Landscape:  Charles Ross and Star Axis (Webcast)
Running Time:
00:10:19
Join the Exploratorium's Dr. Paul Doherty as he visits a "sculpture to observe the stars" in northern New Mexico, where the Sangre de Cristo Mountains meet the eastern plains. There artist Charles Ross is creating an art installation that is also a star observatory. This major earthwork has two main elements: the Star Tunnel, which allows you to walk through the entire history of the earth's changing alignment to our North Star, Polaris; and the Solar Pyramid, where one can visually experience an hour of the earth's rotation.

Return to Mars:  Red Planet: Up Close and Personal (Webcast)
Running Time:
00:37:05
We stayed up with Exploratorium scientist Ron Hipschman at the Lick Observatory in San Jose, California, for the best view we've had of Mars in a long, long time. At midnight on August 27, Earth and Mars passed closer to one another than they have in 60,000 years. Astronomers were on hand to tell us all about our nearest neighbor—its geography, orbit, and why both NASA and the European Space Agency have chosen this time to launch robotic missions to Mars.

Solar Eclipse:  Eclipse 2001: The View from Zambia (Webcast)
Running Time:
0:59:07
On Thursday, June 21, 2001, a total solar eclipse sped across the Southern Hemisphere. The shadow of the moon first darkened the South Atlantic about 250 miles east of the Uruguay coast. It crossed the Atlantic Ocean, traversed southern Africa and the island of Madagascar, and then vanished into the darkness as night fell over the Indian Ocean. We sent our crew to the country of Zambia to bring images of the total solar eclipse as it happened.
