The BEXUS-ALBEDO project follows the projects BEXUS-IMUFUSION, BEXUS-ELFI and BEXUS-ARESONUS.

REXUS/BEXUS programme

„The REXUS/BEXUS program is realised under a bilateral agency agreement between the German Aerospace Center (DLR) and the Swedish National Space Agency (SNSA). 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 Centre of SSC and the Mobile Rocket Base (MORABA) of DLR, is responsible for the campaign management and operations of the launch vehicles.“

Team

The BEXUS-ALBEDO experiment at Nordhausen University of Applied Sciences is assigned to the BEXUS 38/39 campaign. The flight is planned for October 2026 at the Esrange Space Centre.

The team consists of: Omar Alak, Michel Härter, Ahmed Abbas Jameel Alhamid, Alexander Pehlert, Christoph Bönisch, Christian Feine and, as Senior Scientists, Prof Dr Matthias Viehmann and Prof Dr Klaus-Peter Neitzke.

Objective and technical system

The BEXUS-ALBEDO experiment is planned to investigate radiation components in the ultraviolet to infrared spectral range on the stratospheric balloon. The measurements will be carried out at altitudes of up to around 28 km, accompanied by extreme environmental conditions with temperatures as low as -70 °C and a minimum air pressure in the millibar range. The sensor system will record the radiation in the spectral range from around 250 µm to 10 nm. As part of the evaluation, the atmospheric radiation balance and the albedo effect will be analysed.

Supporter

In addition to DLR, ESA, SNSA, SSC and ZARM, several supporters are accompanying the team and we would like to express our sincere thanks to all of them. They will be added here soon.

Activities

Training week at SSC Esrange with Preliminary Design Review (PDR)

In the period 26.01.2026 until 30.01.2026 the team spent a week training at the Esrange Space Centre, the first EU spaceport on the European continent. The focus was on getting to know the SSC, the other teams, the project management and support as well as the balloon system. Agreements were made on the design of the experiments, gondola integration and project organisation.
