    Earth Resources Technology Satellite. Spacecraft engaged in practical applications and uses of space technology such as weather or communication (US Cat C).

  • 1975 January 22 - Landsat 2.  Spacecraft: Landsat 1-2-3. Mass: 953 kg (2,101 lb). Launch Site: Vandenberg. Launch Vehicle: Delta 2000.

    Spacecraft engaged in practical applications and uses of space technology such as weather or communication (US Cat C).

  • 1978 March 5 - Landsat 3.  Spacecraft: Landsat 1-2-3. Mass: 960 kg (2,110 lb). Launch Site: Vandenberg. Launch Vehicle: Delta 2000.

    Spacecraft engaged in practical applications and uses of space technology such as weather or communication (US Cat C).

  • 1982 July 16 - Landsat 4.  Spacecraft: Landsat 4-5. Mass: 1,942 kg (4,281 lb). Launch Site: Vandenberg. Launch Vehicle: Delta 3000.

    Spacecraft engaged in practical applications and uses of space technology such as weather or communication (US Cat C).

  • 1984 March 1 - Landsat 5.  Spacecraft: Landsat 4-5. Mass: 1,938 kg (4,272 lb). Launch Site: Vandenberg. Launch Vehicle: Delta 3000.

    Spacecraft engaged in practical applications and uses of space technology such as weather or communication (US Cat C).

  • 1999 April 15 - Landsat 7.  Spacecraft: Landsat 7. Mass: 1,969 kg (4,340 lb). Launch Site: Vandenberg. Launch Vehicle: Delta 7000.

    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.
