PETREL (Platform for Extra and Terrestrial Remote Examination with LCTF) is a technology demonstration satellite being developed by Tokyo Institute of Technology. The microsatellite is equipped with a multispectral camera, which will be used to carry out two distinct missions. One mission is to survey the sky in ultraviolet wavelengths for the field of time-domain astronomy, and the other is to conduct spectroscopic observations of the Earth.[1] PETREL was planned to be launched as part of the Japanese space agency JAXA's 2022 Innovative Satellite Technology Demonstration-3 mission, but wasn't launched.
