American earth land resources satellite. One launch, 1999.04.15.
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.
Gross mass: 1,969 kg (4,340 lb).

Associated Launch Vehicles
Delta American orbital launch vehicle. The Delta launch vehicle was America's longest-lived, most reliable, and lowest-cost space launch vehicle. Delta began as Thor, a crash December 1955 program to produce an intermediate range ballistic missile using existing components, which flew thirteen months after go-ahead. Fifteen months after that, a space launch version flew, using an existing upper stage. The addition of solid rocket boosters allowed the Thor core and Able/Delta upper stages to be stretched. Costs were kept down by using first and second-stage rocket engines surplus to the Apollo program in the 1970's. Continuous introduction of new 'existing' technology over the years resulted in an incredible evolution - the payload into a geosynchronous transfer orbit increasing from 68 kg in 1962 to 3810 kg by 2002. Delta survived innumerable attempts to kill the program and replace it with 'more rationale' alternatives. By 2008 nearly 1,000 boosters had flown over a fifty-year career, and cancellation was again announced. More...

- 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: 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.
