Nimbus program
The Nimbus program was a second generation American weather satellite research program . It involved the launch of eight satellites (including one false launch). The Nimbus program was carried out in parallel to the TIROS program . The satellites were in sun-synchronous polar orbits .
Nimbus-7 was NASA's first satellite for global environmental monitoring. Mainly the earth's atmosphere, oceans, ocean-atmosphere exchange and the earth's heat balance were researched. The multispectral line scanner (6 channels) Coastal Zone Color Scanner (CZCS) , which worked until 1986, was specially designed for the observation of ocean color for the first time. The successors to this sensor are SeaWiFS and MODIS on Aqua .
Nimbus B1 crashed into the sea near the coast of California in 1968 after launching from Vandenberg AFB . The plutonium capsules of the two radioisotope generators of the satellite could be recovered undamaged from a relatively shallow water depth.
