The SeaWiFS instrument was launched by Orbital Sciences Corporation on the OrbView-2 (a.k.a. SeaStar) satellite in August 1997, and collected data from September 1997 until the end of mission in December 2010. SeaWiFS had 8 spectral bands from 412 to 865 nm. It collected global data at 4 km resolution, and local data (limited onboard storage and direct broadcast) at 1 km. The mission and sensor were optimized for ocean color measurements, with a local noon (descending) equator crossing time orbit, fore-and-aft tilt capability, full dynamic range, and low polarization sensitivity.

The SeaWiFS instrument has scanning mechanisms to
drive an off-axis folded telescope and a rotating halfangle
mirror. Incoming scene radiation is collected
by the folded telescope and reflected onto the rotating
half-angle mirror. The collected radiation is then relayed
through dichroic beam splitters to separate the radiation
