American earth land resources satellite. Earth Observing satellite built by Lockheed Martin for NASA, USA. Launched 1993 - 1999. Used the TIROS-N Bus bus.
Landsat 7's single instrument was the Enhanced Thematic Mapper Plus (ETM+), a scanning radiometer with visible and infrared bands giving 30-meter resolution in the visible bands and 15-m resolution in black and white. The spacecraft was derived from the Tiros-N/DMSP weather satellites.

Spacecraft: Landsat 7.
USAF Sat Cat: 25682 . COSPAR: 1999-020A. Apogee: 703 km (436 mi). Perigee: 702 km (436 mi). Inclination: 98.20 deg. Period: 98.80 min.
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.
