Landsat 7

---

Status: Operational 1999. First Launch: 1999-04-15. Last Launch: 1999-04-15. Number: 1 . Gross mass: 1,969 kg (4,340 lb).

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.

Family: Earth, Earth land resource sat, Sun synchronous orbit. Country: USA. Spacecraft: Landsat. Launch Vehicles: Thor, Delta, Delta 2 7000, Delta 7920-10. Launch Sites: Vandenberg, Vandenberg SLC2W. Agency: NASA Greenbelt, Aerospace. More at: 6649. Bibliography: 2, 3822, 3823, 3824, 3826, 4.

• Landsat 7 - . Mass: 1,969 kg (4,340 lb). Nation: USA. Agency: NASA Greenbelt. Manufacturer: Valley Forge. Program: Landsat. Class: Earth. Type: Earth resources satellite. Spacecraft Bus: Landsat 7. Spacecraft: Landsat 7. USAF Sat Cat: 25682 . COSPAR: 1999-020A. Apogee: 703 km (436 mi). Perigee: 702 km (436 mi). Inclination: 98.2000 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.
