MAQSAT


European technology satellite. 4 launches, 1997.10.30 (MAQSAT-H/TEAMSAT) to 2005.02.12 (Maqsat 3). MAQSATs were mass model and technology satellites built by Kayser-Threde, Munich, and lofted during the test flights of the Ariane 5.

MAQSAT-H was a dummy communications satellite instrumented to report the actual payload bay environment during launch. It also included the TEAMSAT technology experiment payload, developed by ESTEC. TEAMSAT ejected a subsatellite, the Young Engineers Satellite, also with several experiments. MAQSAT-B was a smaller dummy satellite in the lower bay of the SPELTRA dual launch adapter. On a later launch Maqsat-3 was a similar dynamic model of Eutelsat W2, instrumented and within the SPELTRA adapter.

First Launch: 1997.10.30.
Last Launch: 2005.02.12.
Number: 4 .

  • Ariane 5 The Ariane 5 was a completely new design, unrelated to the earlier Ariane 1 to 4. It consisted of a single-engine Lox/LH2 core stage flanked by two solid rocket boosters. Preparatory work began in 1984. Full scale development began in 1988 and cost $ 8 billion. The design was sized for the Hermes manned spaceplane, later cancelled. This resulted in the booster being a bit too large for the main commercial payload, geosynchronous communications satellites. As a result, development of an uprated version capable of launching two such satellites at a time was funded in 2000. More...

  • Ariane 5ECA French orbital launch vehicle, first version of the evolved Ariane 5. The solid booster motors propellant load was increased by 2.43 tonnes and the case was welded, for a weight saving in dry mass of 1.9 tonnes. The core was powered by an improved Vulcain 2 engine. The oxygen-rich cycle of the engine allowed the oxygen bulkhead to be moved within the stage, resulting in a 15.2 tonne increase in propellant in the core. A new Lox/LH2 upper stage, using the HM7B engine and oxygen tank from the Ariane 4 series, replaced the storable propellant EPS stage of earlier models. The result was an increase in payload to geoscynchronous transfer orbit from 6 tonnes to 10.5 tonnes. More...

Associated Launch Sites
  • Kourou After the agreement with newly independent Algeria for France to evacuate their launch sites in that country, a location near Biscarosse was selected for French missile testing. However since only launches westwards across the Bay of Biscay could be made from this site, it was unsuitable for France's Diamant orbital launch vehicle. After reviewing 14 potential sites, a location in the South American French colony of Guiana was selected. This would allow over-water launches to a tremendous range of possible orbital inclinations -- from -100.5 deg to 1.5 deg. Being near the equator, it would provide the maximum assist from the earth's rotation for launches into equatorial orbits. The decision was formalized in April 1964 and in July 1966 ELDO chose the site for future launches of the Europa II launch vehicle. More...

Apogee: 35,491 km (22,053 mi). Perigee: 1,017 km (631 mi). Inclination: 7.5000 deg. Period: 641.20 min. Maqsat 3 was an instrumentation package used to monitor performance of the Ariane 5 booster. At T+12:43 the Speltra adapter cover separated revealing Maqsat-3. At T+15:14 the EPS stage Aestus engine ignited and burned until T+31:00. At this point on a normal mission the satellite would separate from the EPS, but to avoid creating space debris Maqsat remained attached to the EPS. The EPS/Maqsat-3 was placed in a 1027 km x 35863 km x 7.0 degree geostationary transfer orbit.
