Its fortunes revised with the establishment of Mid-Atlantic Regional Spaceport in 2005 and orbital launches resumed in 2010. More...

Wallops Island DZ Chronology


1996 November 4 - . 17:08 GMT - . Launch Site: Wallops Island DZ. Launch Pad: 37.0 N x 72.0 W. Launch Platform: L-1011. LV Family: Pegasus. Launch Vehicle: Pegasus XL. LV Configuration: Pegasus XL F14. FAILURE: The rocket functioned perfectly but the separation system failed to release the payload.. Failed Stage: P.
  • HETE - . Nation: USA. Agency: NASA Greenbelt. Program: STEDI. Class: Astronomy. Type: X-ray astronomy satellite. Spacecraft: HETE. Decay Date: 2002-04-07 . USAF Sat Cat: 24645 . COSPAR: 1996-061A. Apogee: 555 km (344 mi). Perigee: 487 km (302 mi). Inclination: 38.0000 deg. Period: 95.00 min. The High Energy Transient Experiment (HETE) was an international mission led by The Massachusetts Institute of Technology (MIT). Its prime objective was to carry out the first multiwavelength study of gamma ray bursts (GRBs) with UV, X-ray, and gamma ray instruments. A unique feature of the mission was its capability to localise bursts with several arcsecond accuracy, in near real-time aboard the spacecraft. These positions were to be transmitted to the ground, and picked up by a global network of primary and secondary ground stations (SGS), enabling sensitive follow-up studies. However the satellite was never released from its payload fitting. Although signals were received, the solar panels could not deploy, and it went silent after a few days when its batteries ran down.
