NASA Will Try Again Friday for CALIPSO and CloudSat Launch
 
 

The launch of NASA's CALIPSO (Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations) and CloudSat satellites from Vandenberg Air Force Base, Calif., has been rescheduled for tomorrow morning, April 28, at 6:02 a.m. EDT. Launch commentary on NASA TV begins at 4 a.m. EDT.

Yesterday, engineers and mission managers assessed a suspect temperature sensor on the Boeing Delta II rocket's second stage. Following a thorough data analysis, they concluded the unusual temperature sensor 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 itself. They concluded the sensor does not require replacement and can fly as is.

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

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.

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 http://www.nasa.gov/multimedia/nasatv. A recorded CloudSat and CALIPSO launch status update is available at: (805) 734-2693.

CALIPSO is managed by NASA Langley. 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.
