HOUSTON -- NASA will hold a series of news media briefings Sept. 8 - 9 to preview 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 the Johnson Space Center and the Goddard Space Flight Center in Greenbelt, Md. Questions also will be taken from other participating NASA locations.

Shuttle Atlantis' 11-day flight, designated STS-125, is targeted for launch Oct. 8 and will include five spacewalks to refurbish and upgrade the telescope with state-of-the-art science instruments. Replacing failed hardware on Hubble will extend the telescope's life into the next decade.

U.S. news media planning to attend the briefings at Johnson must contact the newsroom there at 281-483-5111 by Sept. 2 to arrange for credentials. All reporters who are foreign nationals must contact the newsroom by Aug. 8.

On Sept. 9, Atlantis' seven astronauts will be available for round-robin interviews at Johnson. Reporters planning to participate in-person or by phone must contact Gayle Frere at 281-483-8645 by Sept. 2 to reserve an interview opportunity.

Scott Altman will command Atlantis' crew, which includes Pilot Gregory C. Johnson, and Mission Specialists Andrew Feustel, Michael Good, John Grunsfeld, Megan McArthur and Mike Massimino. The spacewalkers are Good, Grunsfeld, Feustel and Massimino. McArthur is the flight engineer and lead for robotic arm operations.

Along with the briefings to preview the Hubble servicing mission at Johnson, media will have an opportunity during the afternoon of Sept. 8 to review new equipment being developed for NASA's Constellation Program. Constellation is building America's next human spacecraft, which will fly astronauts to low Earth orbit, the moon and beyond. During the review, media will see items that include concepts of a new spacesuit, a pressurized rover vehicle for astronauts, and a mockup of the Orion crew capsule.
