NASA'S CLOUDSAT AND CALIPSO LAUNCH RESCHEDULED

NASA's CloudSat and CALIPSO launch from Vandenberg Air Force Base,
Calif., is scheduled for 6:02 a.m. EDT Friday, April 28. Launch
commentary on NASA TV begins at 4 a.m. EDT.

On Wednesday, engineers and mission managers assessed a suspect
temperature sensor on the Boeing Delta II rocket's second stage. They
concluded the unusual temperature readings observed during the
previous two launch attempts were primarily the result of higher
temperature pressurization rates and are not indicative of any defect
in the sensor. The sensor does not require replacement and can fly as
is.

Weather is not expected to be a concern for Friday's launch.

Media covering the launch on Friday should meet at the Vandenberg main
gate at 5 a.m. EDT for escort to the press site. For media
accreditation, call Staff Sgt. Allen Puckett at (805) 606-3595 at the
30th Space Wing Public Affairs Office.
