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.

• 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.References: 1910.

Kaiser-Threde developed a new payload service system for MAXUS 7, providing 2 independent TV-links with 2 high power HF transmitters and GPS. The recovery system was a BAL ORSA system, modified by Kaiser-Threde, including parachute from DLR.
