EOS Chemistry 1 uses a NGST (TRW) T-330 class (EOS Common Spacecraft) bus. Launch is in 2003 Jun by Delta 7920-10L; the 10L fairing is a 1-m stretch on the standard 10-ft fairing. Orbit is 705 x 705 x 98.2 A-Train with 1:38PM ascending node. (or 1:45?)

Mass 3112 kg (Delta kit) or 2967 kg (NASA kit). 134 kg prop. Size 2.7 x 2.3 x 6.9m with 15m panel, span 17.4m.

Mission is to study trace gases, pollutants such as CFCs, and the ozone layer. The satellite will form the tail of the A-train constellation behind Aqua and the other train members. Control from GSFC FOT.
