Find out what sunsets look like on Mars and what makes the red planet red with images taken by the MERs’ cameras

Come to the Exploratorium and see the first images from the Mars Rover Spirit. Learn about the Mars missions and the tools used to explore Mars.

SETI is a scientific effort seeking to determine if there is intelligent life outside Earth. We were at Aricebo Radio Observatory in March 2003 when scientists listened to the most promising transmissions from UC Berkeley’s SETI@home search. Join the Exploratorium’s Ron Hipschman and special guest Dan Werthimer, chief scientist and principal investigator for the SETI Institute’s efforts, including Arecibo Observatory’s search of artificial radio signals coming from other stars.

See an 8 minute video of the planet Mars from the James Lick Observatory telescope!

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.

Exploratorium staff Ron Hipschman and Robyn Higdon sum up the last five days of spacewalks, and show a couple of good-bye conferences with the shuttle astronauts.

The Advanced Camera for Surveys (ACS) was successfully installed. In preparation for the installation of the NICMOS Cooling System tomorrow, the astronauts also installed the Electronics Support Module. We also talk with Massimo Stiavelli, a scientist at the Space Telescope Science Institute about his involvement with the ACS and the future Wide Field Planetary Camera 3 (WFPC3) scheduled to be installed during the next servicing mission in 2004.

Learn about the successful replacement of the Power Control Unit (PCU) and listen as we talk with Mark Clampin, part of the team that developed the Advanced Camera for Surveys scheduled for installation tonight.

We learn about Hubble's new solar arrays, and Dr. Bruce Margon talks about the future of Hubble and about the Next Generation Telescope, which will eventually replace Hubble.

In an exclusive taped interview, Hubble payload commander and astronaut John Grunsfeld discusses how astronauts who'll be servicing a telescope in space train in a giant pool at the Johnson Space Center. We'll also show an interview with space engineer Amy Ross, filmed in the space suit laboratory at Johnson.
