REXUS/BEXUS

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 a collaboration with the European Space Agency (ESA).

REXUS/BEXUS thus gives students from universities across Europe the possibility to do scientific and technological research on rockets or balloons and every year the REXUS/BEXUS programme launches two balloons and two rockets resulting in a total of 20 experiments that are designed and built by students.

Through a collaboration between the Swedish National Space Board (SNSB) and ESA the Swedish share of the payload on the rockets and balloons are available to students from across several other European countries. This well developed cooperation and collaboration also allows the students to get expert feedback from DLR, SSC, ZARM and ESA to prepare them for the launch. Both the rockets and balloons are then launched from Esrange Space Centre in northern Sweden.

Rexus

The REXUS project, short for Rocket EXperiments for University Students, is the name of the sounding rocket used to send the experiments up to a maximum altitude of approximately 90 km and 3 minutes space time. The REXUS project is dedicated to provide an experimental space platform for students in the field of aerospace technology. Each rocket can carry four experiment modules with the diameter 355,6 mm, a total length of maximum 800 mm and an available mass for experiments up to approximately 40 kg.

 

The REXUS rocket is based on an improved Orion rocket with a total length of 5,22 meters and a total launch mass of approximately 519 kg. A picture from the user REXUS user manual depicting the rocket can be seen below. The rocket is lunched around May each year.

Bexus

The BEXUS project, short for Balloon EXperiments for University Students, is a stratospheric ballon used to send student created experiment to a maximum altitude of 25-30 km where they will stay for a few hours depending on weather conditions and payload mass. The total volume of the balloon 12000 m³ (comparable to the volume of 5 Olympic sized swimming pools).

 

The BEXUS balloons can lift a payload mass of approximately 40-100 kg. The BEXUS balloons is launched in September or October. A picture of the launch of the BEXUS balloon from the BEXUS user manual can be seen below:

Other REXUS/BEXUS projects

DIANE

DIANE_Logo

The team of DIANE (Dipole Inflatable ANtenna Experiment) is developing a 7 metres long dipole antenna made of textile, which is going to be inflated under space conditions on the REXUS 21 rocket. By recording the inflation process with cameras and performing a shortwave radio transmission, the designs usability will be verified. The aim is to create a powerful but lightweight antenna with a small pack size for future CubeSat missions.

RaCoS

racos_logo_600x600_transparentRaCoS (Rate Control System) is an experiment part of REXUS 22 which will be launched in 2017. The experiment shall reduce and control the angular rate of the REXUS sounding rocket in the roll axis by using a cold gas system. Therefore, a control algorithm shall use the measured angular rates to calculate opening times for valves regulating the gas jets.
