• The Technology Experimental Vehicle (TET-1) entered Earth's atmosphere on November 18, 2022 and burned up completely.• Research and industry have used TET-1 since launch in 2012 as part of the OOV-TET-1 mission to test new products under space conditions.• The small satellite became part of the FireBIRD mission in November 2013 and provided data for the analysis of high-temperature events on the Earth's surface. A total of about 7,600 recordings were made. Within the overall mission, around 150 scientific publications as well as bachelor's and master's theses and dissertations have emerged.<snip>Until its re-entry on November 18, 2022, TET-1 was still active, could receive commands, send readings and control its position autonomously. The TET-1 satellite burned up completely on re-entering the atmosphere after 10 years in orbit.
