 CALIPSO Launch Scrubbed

CALIPSO Launch Scrubbed

By SOP newswire

Today's attempt to launch the CALIPSO and CloudSat satellites was scrubbed at T-48 seconds due to loss of the primary and backup phone communications between the Mission Director Center at Vandenberg Air Force Base and the Centre National d'Etudes Spatiales (CNES) Space Command in Toulouse, France. The NASA launch manager has directed his team to reset the launch systems and prepare for another opportunity to launch the mission tomorrow.

CALIPSO and CloudSat are flying into space aboard the swift and dependable Boeing Delta II rocket. With more than 300 successful flights, the dual-stage Delta II is NASA's medium-size payload specialist. Liftoff of the flight is scheduled for 6:02 a.m. EDT from Space Launch Complex 2.

CALIPSO and CloudSat are set to fly into orbit aboard a Boeing Delta II rocket. The Delta II is designed to boost medium-sized satellites and robotic explorers into space. NASA selected a model 7420-10C for this mission, which is a two-stage rocket equipped with four strap-on motors and a protective 10-foot payload fairing.

The CALIPSO and CloudSat spacecraft are a pair of Earth-observing satellites designed to study clouds from orbit. The Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) satellite is equipped to examine the role that clouds and airborne particles play in regulating Earth's weather, climate, and air quality. CloudSat is an experimental satellite using radar to detect clouds and aerosols from space. CloudSat has special significance as the latest spacecraft poised to join NASA's "A-Train" constellation of environmental satellites. CALIPSO and CloudSat spacecraft are sharing the same rocket for their trip into Earth orbit.
