View Two NASA Events Online This Thursday

This Thursday, NASA will broadcast two events for you and your class to enjoy: a glimpse into how NASA trains its astronauts and a milestone spacewalk outside the International Space Station.

Astronaut Training Focus of Engineers Week Webcast for Students

Students around the world are invited for an inside look at how NASA prepares astronauts for life aboard the International Space Station during a live webcast Thursday, Feb. 26, from 1 to 2 p.m. EST. The event is free and can be viewed on the Internet at:

The Space Station Today Webcast, hosted by NASA's Digital Learning Network, in tandem with this year's National Engineers Week (Feb. 22-28), will originate from NASA's Johnson Space Center (JSC) in Houston. It will feature live discussions and opportunities to ask questions of NASA astronaut trainer Mark Sonoda. The program also will include a special visit from veteran astronaut and NASA engineer Bonnie Dunbar, JSC's Deputy Associate Director of Biological Sciences and Applications.

The webcast will show students the people and skills that make space exploration a reality. The event also will feature other educational segments, including "The Cool Experiment of the Day," "Web site Pick of the Month" and "Space Station Trivia!"

International Space Station Spacewalk

This month, for the first time, an International Space Station crew will conduct a spacewalk with all crewmembers working outside the vehicle. This milestone event will be covered live on NASA Television Feb. 26. Coverage will begin at 3 p.m. EST with commentary and available downlink television.

Expedition 8 Commander and NASA Science Officer Mike Foale and Flight Engineer Alexander Kaleri will work outside the Station for a five-and-a-half hour excursion to replace technological experiments and survey the exterior of the complex. Foale and Kaleri have a total of seven spacewalks to their credit. It will be the 52nd spacewalk in support of the assembly and maintenance of the Station.

For the International Space Station, a spacewalk involving all crewmembers is a first. However, the Russian and U.S. space programs are very experienced in spacewalks of this kind. From the Russian Salyut and Mir space stations, cosmonauts performed about 50 two-person crew spacewalks without a crewmember inside.

When American astronauts walked on the Moon, no one was inside the lunar modules. Also, during the first four Space Shuttle missions, which had only two crewmembers each, astronauts were prepared to do two-person spacewalks in the event of a contingency.

NASA Television is available on AMC-9, transponder 9C, C-Band, located at 85 degrees west longitude. The frequency is 3880.0 MHz. Polarization is vertical, and audio is monaural at 6.80 MHz. For information about NASA TV on the Internet, visit:
