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.[2] PETREL was originally planned to be launched on a Epsilon rocket flight in 2022 along with the rest of JAXA's Innovative Satellite Technology Demonstration-3 mission satellites, but was not launched. As of September 2024, PETREL is scheduled to be launched during fiscal year 2025 on the first H3-30 test flight.[1]

Overview
PETREL's role differs depending on its position in orbit: while inside Earth's shadow it will conduct astronomical observations, and while outside it will function as an Earth observation satellite.[2][3]
PETREL will conduct wide field observations in ultraviolet, which will work in tandem with ground-based observatories to study time-domain multi-messenger astronomy. PETREL is a pathfinder for the ULTRASAT mission.[4]
As an Earth observation satellite, PETREL will perform multispectral observation of both the land and seas to acquire data for use in agriculture and aquaculture.[5] PETREL's ocean observation will measure the level of plankton and nutrients in the waters, which the aquaculture industry will utilize to help ensure a stable amount of catches.[6]
