2003-048A
Launch by 2SLS/LMAO, the LMMS satellite DMSP S-20 was built by LMMS/East Windsor and had been stored at Sunnyvale. The satellite is 1960 kg full, probably about 1300 kg on orbit.
It was the first to carry a full 5D-3 set of instruments.
It is 4.4m long 1.22m dia with 6.6m x 2.7m solar panels. Two steel despin cables 4.6m long and 0.006m dia. 10 days after launch the OLS cover (1.0m x 0.4 x 0.4m) and the OLS cooler cover (0.30 x 0.02m) will be jettisoned.
Launch in Jan 2001 was cancelled due to problems with the DMSP IMU. Multiple delays led to an Oct 2003 launch. After launch the satellite is turned over to NPOESS and operated by NOAA's Office of Satellite Operations.
Cover name is USA-172.
