NASA Will Try Again Tomorrow for CALIPSO and CloudSat Launch

The launch of NASA's CloudSat and CALIPSO (Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations) satellites from Vandenberg Air Force Base, Calif., was scrubbed this morning at 4:24 a.m. EDT due to thick clouds.

Launch has been rescheduled for Thursday, April 27, at 6:02:37 a.m. EDT. Launch commentary on NASA TV starts at 4 a.m. EDT. A recorded CALIPSO and CloudSat launch status update is available at: (805) 734-2693.

To record the launch from NASA TV go to MPEG-2 digital C-band signal on AMC-6, at 72 degrees west longitude, Transponder 17C, 4040 MHz, vertical polarization. To view the launch at home on the computer go to:

Some NASA Langley Research Center employees are expected to gather to watch tomorrow's launch attempt. Media wishing to join them should call Kathy Barnstorff at 344-8511 and meet at the NASA Langley main gate no later than 5:15 a.m.

NASA Langley leads the CALIPSO (Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations) project. Data from CALIPSO will help scientists better understand Earth's clouds and airborne particles: answering questions about how they form, evolve, affect water supply, climate, weather and air quality. Launching on the same rocket is another NASA satellite, CloudSat. The two will fly just 15 seconds apart as part of NASA's "A-Train," a constellation of several Earth-observing satellites.
