Orbview


American civilian surveillance satellite. 2 launches, 2001.09.21 (Orbview-4) and 2003.06.26 (Orbview 3).

The OrbView imaging satellite, built by Orbital, was a 368 kg box-shaped spacecraft carrying a 1-m resolution panchromatic camera and an 8-m resolution 200-channel hyperspectral imager with a 0.45-meter aperture. It was to be used by the US Air Force.

Gross mass: 368 kg (811 lb).

  • Taurus American all-solid orbital launch vehicle. Pad-launched launch vehicle using Pegasus upper stages and Castor-120 first stage. First launch used slightly larger Peacekeeper ICBM first stage instead of Castor-120. Under a 2002 contract from Boeing, Orbital developed a three-stage version of Taurus to serve as the interceptor boost vehicles for the US government's missile intercept system. The firm portion of the company's contract, awarded in early 2002, was valued at $450 million and extended through 2007. More...

Orbview Chronology


2001 September 21 - . 18:49 GMT - . Launch Site: Vandenberg. Launch Complex: Vandenberg 576E. LV Family: Pegasus. Launch Vehicle: Taurus 2110. LV Configuration: Taurus 2110 T6. FAILURE: A problem a few seconds after first stage separation caused the rocket to go off course; it recovered and the remainder of the stages fired, but final cutoff velocity was too low to reach a sustainable orbit.. Failed Stage: G.
  • Orbview-4 - . Mass: 368 kg (811 lb). Nation: USA. Agency: Orbimage. Manufacturer: OSC. Program: Orbview. Class: Surveillance. Type: Civilian surveillance satellite. Spacecraft: Orbview. COSPAR: F010921A. Launch delayed from June 27, July 18/22, August 12/21 and September1. The Orbital Sciences Taurus 2110 failed to remain in orbit. A problem a few seconds after first stage separation caused the T6 rocket to go off course; the rocket recovered and the remainder of the stages fired, but final cutoff velocity was too low to reach a sustainable orbit. The Castor 120 zero stage was on course but the Orion 50S first stage motor went off course. The satellites separated from the final stage as planned but burned up in the earth's atmosphere northeast of Madagascar before completing the first orbit. The final orbit was about 75-80 km x 425-430 km x 97 deg. The primary payload was the OrbView-4 imaging satellite. OrbView-4, built by Orbital, was a 368 kg box-shaped spacecraft carrying a 1-m resolution panchromatic camera and an 8-m resolution 200-channel hyperspectral imager with a 0.45-meter aperture. It was to be used by the US Air Force.

2003 June 26 - . 18:55 GMT - . Launch Site: Point Arguello WADZ. Launch Pad: 36.0 N x 123.0 W. LV Family: Pegasus. Launch Vehicle: Pegasus XL. LV Configuration: Pegasus XL F34.
  • Orbview 3 - . Mass: 304 kg (670 lb). Nation: USA. Agency: McLean. Program: Orbview. Class: Earth. Type: Earth resources satellite. Spacecraft: Orbview. Decay Date: 2011-03-13 . USAF Sat Cat: 27838 . COSPAR: 2003-030A. Apogee: 455 km (282 mi). Perigee: 452 km (280 mi). Inclination: 97.3000 deg. Period: 93.70 min. One-meter-resolution commercial imaging satellite. Orbview-3 used an Orbital Leostar bus and had a launch mass of 304 kg (including ca. 50 kg of hydrazine for orbit raising and the 66 kg science instrument). Launch had been delayed from September 2002, April 30, May 9 and 23
