Landsat 7 Chronology

15 April 1999 Landsat 7 Program: Landsat. Launch Site: Vandenberg . Launch Vehicle: Delta 7925. Mass: 1,969 kg. Perigee: 701 km. Apogee: 703 km. Inclination: 98.2 deg.

The vehicle entered a 175 km x 706 km x 98.2 deg initial orbit. 57 minutes after launch the Delta stage burned again to circularize the orbit at 668 km x 698 km and Landsat 7 separated from the stage. The Delta stage then burned to depletion of its propellant, into a 184 km x 710 km x 107.5 deg orbit that would decay quickly. The Landsat 7 remote sensing satellite was to be operated by NASA/Goddard until October 2000, when operations would be transferred to the US Geological Survey.
