 2006-016A


An ESSP with a BCP RS-2000. Launch by Delta 7420-10 with Calipso under a DPAF fairing.

Size 2.5 x 2.3 x 2.0 m mass 848 kg full (773 kg dry?). 5.1m span. Cloudsat flies in formation with Picasso-Cena and carry a 94 GHz nadir-looking radar. Both satellites will also fly in looser formation with Aqua as part of the A-Train Constellation: Aqua, Cloudsat, CALIPSO, PARASOL and Aura. Combined launch mass 1295 kg.

Orbit 717 x 734 x 98.08. A-Train 1:31PM.

Joint NASA/Canada. Carries a cloud profile radar. an IR O2 spectrometer, and a visible imager. It uses the data from the Picasso lidar in combination with its own radar. Launch 2003.

Ground control by RSC/Kirtland, using AFSCN; mission management by JPL.

Now STP P00-4 SMC-801, Cloud and Aerosol Vertical Profiler.

Calipso is mounted on the upper DPAF cone-cylinder. The lower DPAF cone remains attached to the Delta second stage.
