Nimbus B was a meteorological satellite launched as part of the Nimbus program. It was released on May 18, 1968 from the Vandenberg Air Force Base, Lompoc, California, by means of a Thor-Agena launch vehicle, together with the SECOR 10 satellite. Nimbus B never achieved orbit because a malfunction in the booster guidance system forced the destruction of the spacecraft and its payload during launch.
The Radioisotope Thermoelectric Generator SNAP-19 RTG was salvaged from the water, refurbished and later flown on Nimbus 3. [3]
