The Space Infrared Telescope for Cosmology and Astrophysics (SPICA), was a proposed infrared space telescope, follow-on to the successful Akari space observatory. It was a collaboration between European and Japanese scientists, which was selected in May 2018 by the European Space Agency (ESA) as a finalist for the next Medium class Mission 5 (M5) of the Cosmic Vision programme, to launch in 2032.[6] At the time the other two finalists were THESEUS and EnVision, with the latter that was eventually selected for further development.[7] SPICA would have improved on the spectral line sensitivity of previous missions, the Spitzer and Herschel space telescopes, between 30 and 230 μm by a factor of 50—100.[8]

A final decision was expected in 2021,[4] but in October 2020, it was announced that SPICA was no longer being considered as a candidate for the M5 mission.[9][10]
