mission extension
After more than three years in orbit, the mission of the CHEOPS space telescope on the 7th March 2023 was extended by ESA.
Led by the University of Bern in collaboration with the University of Geneva, CHEOPS is a joint mission of the European Space Agency (ESA) and Switzerland.

Since its launch in December 2019, the satellite's extremely precise measurements have contributed to several key discoveries in the field of exoplanets.

The extension will make it possible to study these fascinating worlds around other stars in even more detail.

We have only scratched the surface of the capabilities of CHEOPS, there is much more science that can be done with the satellite and we look forward to exploring it during the extension.
Prof. Willy Benz, CHEOPS principal investigator
Although CHEOPS main objective was the characterization of exoplanets, CHEOPS is a photometer. So it means that it can do all kinds of photometric measurements and it can also do solar system objects. As you may know, CHEOPS has recently contributed to the discovery of the rings of the dwarf planet.
Dr. Andrea Fortier, CHEOPS instrument scientist
A very exciting result would be the discovery of the first exomoon.
CHEOPS is precise enough to find exomoons as small as the planet Mars, which is twice the size of our Moon. If such moons exist in the systems we observe, we could find them during the extended mission.
