Max Valier was a 15kg (33lb) X-ray telescopic satellite which was built in collaboration with the Technologische Fachoberschule "Max Valier" in Bozen, the Technologische Fachoberschule "Oskar von Miller" in Meran and the Amateurastronomen "Max Valier". The Max Planck Institute for Astrophysics provided the small X-ray telescope μRosi, which allowed amateur astronomers to observe the sky in X-ray wavelength for the first time. It was launched with the help of the OHB in Germany by an Indian PSLV-C38 rocket on 23 June 2017.[1][2] It re-entered the Earth's atmosphere on 30 June 2024, after remaining operative for 7 years and 7 days.[3]
