Maxus
The MAXUS micrograviy program was a collaboration between Sweden and Germany. The single-stage vehicle developed for the program used a Castor 4B motor, the largest fired from Western Europe.

This allowed the experiments lofted to experience 12 minutes and 40 seconds of microgravity. The recoverable and reusable 720 kg payload module could accomdoate six to eight separate experiments.

Payload: 720 kg (1,580 lb) to a 850 km altitude. Failures: 1. Success Rate: 87.50%. First Fail Date: 1991-05-08. Last Fail Date: 1991-05-08. Launch data is: continuing.

Associated Launch Sites
  • Kiruna The sounding rocket launch site at Kiruna was officially opened in September 1966 under the auspices of ESRO (European Space Research Organisation). When ESA was created in 1972 and replaced ESRO, Kiruna came under the management of the Swedish Space Corporation, a state-owned limited liability company under the Swedish Ministry of Industry. The 'Esrange' is located 45 km from the town of Kiruna and has seven permanent pads able to launch the largest sounding rockets, including the Black Brant 9, Skylark 12, and Castor 4B-boosted vehicles.

Maxus Chronology


1991 May 8 - . 03:54 GMT - . Launch Site: Kiruna. Launch Vehicle: Maxus. LV Configuration: Maxus MAXUS 1. FAILURE: Failed..
  • Microgravity mission - . Nation: Sweden. Agency: SSC. Apogee: 157 km (97 mi). Microgravity experiments. Recovered, although it reached only a fraction of the planned altitude. The MAXUS sounding rocket program began in 1989 and the first launch took place in 1991.The program was a joint venture between the Swedish Space Corporation and the German space company EADS-ST. The Maxus program was financed by ESA. The scientific objective was to perform experiments during 12-13 minutes of microgravity (10-4 g) using a single stage sounding rocket motor. The motor, a Castor 4B, had a maximum acceleration of 13 g, a top speed of 3500 m/sec and reached an apogee of around 750 km depending on the payload mass.
