CATSat-1 (NORAD 44033, COSPAR 1998-067PZ) was a US satellite that re-entered Earth's atmosphere on 13 Apr 2021, launched on 5 Dec 2018 on the 77KM No. 17501 mission. It was operated by APL as part of the APL Cube programme. The spacecraft was built by APL/BLCAN on the Cubesat 3U bus, with a mass of 4 kg. Like most satellites in low orbits, it was gradually slowed by atmospheric drag until re-entry.
