Associated Launch Sites
  • Wallops Island Small NASA launch site for sounding rocket launches and occasional Scout launches to orbit. Air launches are conducted from the Drop Zone Wallops Island, 37.00 N 72.0 W. With the last orbital launch in 1985 and the decline in sounding rocket launches, Wallops fell into near-disuse as a launch center. Its fortunes revised with the establishment of Mid-Atlantic Regional Spaceport in 2005 and orbital launches resumed in 2010. More...
  • White Sands White Sands Missile Range occupies an area 160 x 65 km in the Tularosa Basin of southern New Mexico, across the Sacramento Mountain range from Roswell. In the 1930's, Robert Goddard, after surveying weather conditions and population densities, had selected Roswell for his pioneering rocket tests. White Sands, a true desert area, was even more unpopulated than Roswell. German advances in rocketry during World War II impelled the US Army to begin programs to exploit this technology. The White Sands Proving Ground was established for testing German and American long-range rockets on 9 July 1945. Seven days later the first atomic bomb was exploded at Trinity Site, near the north boundary of the range. The first launch of a Tiny Tim rocket was on 26 September 1945. On 11 October a Tiny Tim boosted a WAC Corporal rocket from the tower. This was the first use of Launch Complex 33, later to be used for V-2, Nike, Viking, Corporal, Lance and Multiple Launch Rocket System testing. More...
  • Woomera After World War II British government recognized the need for a large range to test the incredible array of long-range missile systems then planned. After considering sites in Canada, it was decided that Australia would best meet the projected needs. The Long Range Weapons Establishment was created on 1 April 1947 as a joint British/Australian enterprise. 23 days later the name Woomera (an aboriginal word of axtlaxtl, or spear thrower) was selected for the new town to be built as its administrative center. Woomera town peaked at a population of 6,000 in the 1960's. Thereafter the progressive cancellation of British missile and space projects put Woomera went into sustained decline. However it played a key role in the history of rocketry, including orbital launches or launch attempts by Black Arrow, Sparta, and Europa boosters. More...

Associated Stages
  • Improved Orion-1 Solid propellant rocket stage. Loaded mass 400 kg. Thrust 13.00 kN. The Improved Orion motor was a bi-phase propellant system that results in thrust levels of approximately 84.5 kN during the first four seconds of motor burn then trailing off to approximately 13.3 kN until burnout around 25 seconds. The fins were generally configured to provide a burn out spin rate of four cycles per second. More...
  • Terrier Mk 70 Oriole-1 Solid propellant rocket stage. Loaded/empty mass 1,038/290 kg. Thrust kN. The basic Terrier mk70 motor was 3.94 m long with a principal diameter of 46 cm. There was a 7.6-cm interstage adapter which allowed for drag separation at Terrier burnout. Typically, the Terrier booster would utilize two spin motors to reduce dispersion and also serve as drag plates. Each Terrier fin was 0.43 square meters in area. Normally, the fins were canted to provide two revolutions per second spin rate at Terrier burnout. More...

Terrier Orion Mk 70 Chronology


2001 October 30 - . 02:31 GMT - . Launch Site: Woomera. LV Family: Terrier. Launch Vehicle: Terrier Orion Mk 70. LV Configuration: Terrier Mk 70 Orion T-Orion 5A. FAILURE: Failure.
  • Hyshot 1 'Hilary' Technology mission - . Nation: Australia. Agency: UQU. Apogee: 100 km (60 mi). First launch attempt in the HyShot Flight Program. The scramjet payload was to be used to verify pressure measurements made of supersonic combustion in The University of Queensland's T4 shock tunnel by those made in an actual flight. A failure of stabilising fins meant that the rocket fell far short of the planned 330-km apogee and the scramjet experiment was not conducted.

2002 July 30 - . 02:05 GMT - . Launch Site: Woomera. LV Family: Terrier. Launch Vehicle: Terrier Orion Mk 70.
  • Hyshot 2 'Hans' Technology mission - . Nation: Australia. Agency: UQU. Apogee: 314 km (195 mi). In the second launch of the HyShot program, the Terrier-Orion Mk70 rocket boosted the payload, which remain attached to the second stage Orion motor, toward a planned apogee of 330 km. After peaking at 314 km, the trajectory was designed so that the payload was moving at Mach 7.6 between 35 km and 23 km on the way down, at which point the measurements of supersonic combustion were made. This was claimed to be the first successful test of a scramjet in flight.

2003 August 1 - . 10:25 GMT - . Launch Site: Wallops Island. LV Family: Terrier. Launch Vehicle: Terrier Orion Mk 70. LV Configuration: Terrier Mk 70 Orion NASA 12.052GT.

  • Dummy Scramjet test - . Nation: USA. Agency: DARPA. Apogee: 20 km (12 mi).

2003 October 24 - . 10:45 GMT - . Launch Site: Wallops Island. LV Family: Terrier. Launch Vehicle: Terrier Orion Mk 70. LV Configuration: Terrier Mk 70 Orion NASA 12.053GT.

  • HyShot 3 - . Nation: Australia. Agency: UQU. Apogee: 325 km (201 mi). The 100-kg test British-design scramjet engine was boosted to an altitude of 314 km during a 10-minute flight. It and the attached second stage then were re-oriented to point back to the Earth. The scramjet was successfully ignited at a speed of Mach 8 in the tiny six-second window of opportunity shortly before impact.

2006 March 30 - . 02:40 GMT - . Launch Site: Woomera. LV Family: Terrier. Launch Vehicle: Terrier Orion Mk 70.
  • Hyshot 4 (JAXA) - . Nation: Australia. Agency: UQU. Apogee: 290 km (180 mi). A repeat of the test four days earlier, this time with a Japanese-designed scramjet. The nosecone of the rocket failed to jettison and therefore scramjet ignition was not achieved. The scramjet and second stage remains were located in the desert and recovered after only 20 minutes of searching.

2008 July 14 - . 10:10 GMT - . Launch Site: Wallops Island. LV Family: Terrier. Launch Vehicle: Terrier Orion Mk 70. LV Configuration: Terrier Mk 70 Orion NASA 41.075NP.
