REXUS/BEXUS

REXUS/BEXUS

With the first flight in 1995, but ongoing almost every year since 2004, now even with two rockets per year, REXUS/BEXUS has had some great results in a wide reaching branch of science.

REXUS/BEXUS are european programs for student experiments. The REXUS/BEXUS program is realised under a bilateral Agency Agreement between the German Aerospace Center (DLR) and the Swedish National Space Board (SNSB). They use balloons and sounding rockets to get the student expermients up to altitude.

Universities all over Europe and teams of Engineers try to get a “seat” on the rocket or balloon. Experts from ESA and DLR provide support for the students throughout their project.

REXUS ROCKET

  • Type: Spin-stabilized rocket, powered by an Improved Orion motor
  • Mass: 515 kg (at launch)
  • Size: 5.6 m long, body diameter 14 in (35.6 cm)
  • Fuel: 290 kg of solid propellant
  • Peak altitude: 80–100 km
  • Payload: Student experiments of max 40 kg, system payload 60 kg
  • Recovery: Helicopter

BEXUS BALLOON

  • Balloon: 10,000 – 12,000 m3 Zodiac 12 SF plastic balloon with helium gas
  • Length of balloon train: 65–100 m from top of balloon to gondola
  • Experiment mass: 40–100 kg
  • Flight duration: 2–5 hours
  • Peak altitude: 20–35 km
  • Recovery: Helicopter

The REXUS/BEXUS programme is realised under a bilateral Agency Agreement between the German Aerospace Center (DLR) and the Swedish National Space Board (SNSB). The Swedish share of the payload has been made available to students from other European countries through the collaboration with the European Space Agency (ESA).

Experts from DLR, SSC, ZARM and ESA provide technical support to the student teams throughout the project. EuroLaunch, the cooperation between the Esrange Space Center of SSC and the Mobile Rocket Base (MORABA) of DLR, is responsible for the campaign management and operations of the launch vehicles.
