Status: Operational 2000. First Launch: 2000-11-21. Last Launch: 2000-11-21. Number: 1 . Gross mass: 566 kg (1,247 lb).

Complementing the New Millennium's Deep Space series, EO-1 was a NASA-Goddard satellite which demonstrated technology for the next generation Landsat. It flew in formation with Landsat-7 for comparison purposes, using a hydrazine thruster to adjust its orbit. The satellite used a MIDEX-derived bus built by Swales Aerospace; dry mass was 566 kg. The main instruments were ALI (Advanced Land Imager) and the Hyperion 220-band imaging spectrometer.

• EO-1 - . Mass: 529 kg (1,166 lb). Nation: USA. Agency: NASA Greenbelt. Manufacturer: Swales. Class: Earth. Type: Earth resources satellite. Spacecraft: EO-1. USAF Sat Cat: 26619 . COSPAR: 2000-075A. Apogee: 703 km (436 mi). Perigee: 702 km (436 mi). Inclination: 98.20 deg. Period: 98.80 min.

  First use of a Delta dual payload attach fitting. The Earth Orbiter 1 satellite was part of NASA's New Millenium Program. Complementing the New Millenium's Deep Space series, EO-1 was a NASA-Goddard satellite which demonstrated technology for the next generation Landsat. It flew in formation with Landsat-7 for comparison purposes, using a hydrazine thruster to adjust its orbit. The satellite used a MIDEX-derived bus built by Swales Aerospace; dry mass was 566 kg. The main instruments were ALI (Advanced Land Imager) and the Hyperion 220-band imaging spectrometer. At 1835 GMT the Delta second stage completed its first burn and entered a 185 x 713 km x 98.2 deg transfer orbit. At 1920 GMT the orbit was circularised and EO-1 separated at 1925 GMT into a 682 x 729 km x 98.2 deg orbit.
