(NET) Spectrum • AT-Astra & GreenBox 2

An Isar Aerospace Spectrum rocket will launch on its third flight to carry two GreenBox satellites for the Austrian company R-Space into orbit. GreenBox 1 is named AT-Astra (aka IOB-01) and represents the first com­mer­cial sa­tel­lite fully developed and built in Austria. It is a platform for IOD (in-orbit demonstration) for experiments from three customers; Austrian companies Enpulsion and SunBooster, and the Portuguese firm Synopsis Planet. The mission will be named "?" by Isar and "R-Space IOD-1" by the customer. Spectrum is a two-stage launch vehicle propelled by liquid propane and LOX, where stage 1 features a cluster of nine Aquila-SL engines and stage 2 one reignitable Aquila-Vac engine. - AT-Astra, a 2U CubeSat, is the first com­mer­cial sa­tel­lite fully developed and built in Austria and will carry experiments from three customers. ENPULSION is one of the world's leading providers of electric propulsion systems based on Field Emission Electric Propulsion (FEEP) technology. On AT-Astra it supports the OOBI project (On-Orbit Behaviour of Indium), heating samples of indium, the propellant used in its FEEP thrusters, to their melting point to observe how liquid metal behaves in microgravity, with images downlinked via the R-Space Greenbox platform. SunBooster is a Graz-based company testing a newly developed solar module in orbit for the first time. Its design combines surface-mount (SMT) micro solar cells with mini blocking diodes to improve resilience against micrometeorites while keeping costs low, targeting a tenfold cost reduction compared with existing space solar modules. Synopsis Planet features a compact, high-performance star tracker that combines precise attitude determination and space-debris detection in a single unit. Developed with the University of Lisbon and funded by PRR New Space Portugal, it processes data on board for real-time star identification and moving-object detection, simplifying spacecraft architecture and reducing downlink needs.
