Vol 45, Week 11: Lunar Broadcast Precursor — Terrestrial Edition
Second test flight of the Isar Spectrum launch vehicle. This launch will carry 5 cubesats and 1 non-separable experiment as part of European Space Agency (ESA)’s “Boost!” program:
* CyBEEsat (TU Berlin)
CyBEEsat is a technology demonstration mission by the Technische Universität Berlin to demonstrate a miniaturized transceiver for the Short Duration Mission (SDM) frequency band and cybersecurity applications.
The 1U CubeSat satellite features innovative on-board hardware as well as radiation tolerant perovskite solar cells. The University of Potsdam, 2BCOM Space GmbH and local SME partners (Berlin Nanosatellite Alliance) support the project with hard- and software.
* TriSat-S (University of Maribor)
* Platform 6 (EnduroSat)
* FramSat-1 (NTNU)
* SpaceTeamSat1 (TU Wien Space Team)
* Let It Go (Dcubed, non-separable experiment)
The cubesats will go to Sun-Synchronous Orbit (SSO).
The Spectrum, manufactured by Isar Aerospace established in 2018, undertook its inaugural launch on 03/30/2025, is non-reusable and is inactive.
Spectrum has 0 successful launches and 1 failed attempts, with a cumulative tally of 1 launches, currently with 6 pending launches in the pipeline.
