WASHINGTON -- NASA has set June 11 as the new no-earlier-than target launch date for the Gamma-ray Large Area Space Telescope, or GLAST, from Cape Canaveral Air Force Station in Florida. The launch window extends from 11:45 a.m. to 1:40 p.m. EDT.

NASA initially had targeted June 7 for the GLAST launch aboard a Delta II rocket. Additional time was needed to replace the rocket's flight termination system battery, which indicated a problem Wednesday.

The GLAST prelaunch news conference is planned for 1 p.m. on Monday, June 9, at NASA's News Center at the Kennedy Space Center. Question-and-answer capability will be available from participating NASA locations.

Placement of remote cameras at Pad 17B is planned for 1 p.m., Tuesday, June 10. On launch day, news media should meet at 10:30 a.m. at the Space Florida parking lot outside Gate 1 of Cape Canaveral Air Force Station.

Launch commentary on NASA Television's Media Channel 103 will begin at 9:45 a.m. on June 11. For complete NASA TV downlink information, schedules and links to streaming video, visit:
