The satellite series is named after Jason of Greek mythology – an adventurer fascinated by the ocean. As global warming continues to increase, the polar icecaps will lose more and more of their mass to the oceans, adding volumes of seawater potentially great enough to swallow islands and permanently flood coastal areas.
Jason-1Jason-1, launched on December 7, 2001, on the same Delta rocket as TIMED, is collecting data on ocean circulation which are intended to enable better climate predictions and understanding of events such as El Niņo. It will improve upon TOPEX/Poseidon's topographic resolution to about 2.5 vertical cm, and also record direct measurements of surface temperatures using a radiometer.
Jason-2 has an on-orbit mass of 525 kg (1,155 lb), a height of 3m (9ft 8in), and a power generation capacity of 511 watts. It orbits at a mean altitude of 1,338 km (831 miles).
