BOLT

BOLT explores Li-Fi for intra-satellite communication: a free-space optical link beaming data between subsystems without radio interference. The mission subjects the hardware to the same shocks, cold starts and potential faults we expect in orbit, giving us a realistic playbook for future payloads.

Building on the research of project SatelLight, we are part of the REXUS/BEXUS Programme, participating in the REXUS 37/38 campaign and flying on REXUS 37. It pushes light-based communications through launch loads and microgravity, helping us map out how optical links behave when the stakes - and the vibrations - are high.

The REXUS/BEXUS programme 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 a collaboration with the European Space Agency (ESA). EuroLaunch, a cooperation between the Swedish Space Corporation (SSC) and the Mobile Rocket Base (MORABA) of DLR, is responsible for the campaign management and operations of the launch vehicles. Experts from DLR, SSC, ZARM and ESA provide technical support to the student teams throughout the project. REXUS and BEXUS are launched from SSC, Esrange Space Center in northern Sweden.
