  Oceanography satellite, launch delayed from August 10 and September 15. Jason 1 was a joint mission between CNES (the French space agency) and NASA/JPL, following on the Topex satellite which carried the Poseidon sea surface altimeter. Jason carried Poseidon 2, as well as orbital tracking experiments and a microwave radiometer which measured the amount of water vapor, allowing path delay errors to be calibrated. The satellite used the Alcatel Proteus bus and had a dry mass of 472 kg plus 28 kg of hydrazine propellant. The JASON/TIMED mission's Boeing Delta 7920-10C second stage reached an initial orbit of 215 x 1343 km x 66.2 deg at 1517 GMT. A second burn at 1559 GMT circularized at apogee to 1320 x 1330 km x 66.0 deg, and the Jason 1 satellite was ejected at 1602 GMT.
