NASA will hold news briefings April 23 to update reporters about the space shuttle's fifth and final servicing mission to the Hubble Space Telescope. NASA Television and the agency's Web site will provide live coverage of the briefings from NASA's Johnson Space Center in Houston and NASA Headquarters in Washington.
Shuttle Atlantis' 11-day flight, designated STS-125, is targeted for launch May 12 and will include five spacewalks to refurbish and upgrade the telescope with state-of-the-art science instruments. As a result, Hubble's capabilities will be expanded and its operational lifespan extended through at least 2014.
The schedule of activities includes (all times Eastern):
8 a.m. -- Video B-roll feed from NASA's Johnson Space Center
9 a.m. -- Shuttle Program overview briefing from Johnson. Panelists
