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.“

The BEXUS-ALBEDO experiment is planned to analyse radiation components in the infrared to light range. The measurements are carried out at altitudes of up to around 28 km, accompanied by challenging environmental conditions with temperatures down to -70 °C and a minimum air pressure in the millibar range. As part of the analysis, the atmospheric radiation balance and the albedo effect (a measure of the proportion of incident solar radiation reflected from a surface) will be analysed.

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.
