Planned[edit]

Name Launch Date Object of Mission Duration
CHEOPS December 2017[14] To learn more about how exoplanets form, probe atmospheres, and characterize super-Earth's.

20% of time will be open to community use.[15]

3.5 (+ 1.5 goal) years
TESS December 2017 (Falcon 9) This is a mission by NASA to search for new exoplanets, rotating so by the end of its two-year

mission it will have observed stars from all over the sky. It is expected to find at least 3,000 new exoplanets.

2 years
JWST October 2018 (Ariane 5) It will look at atmospheres of known exoplanets and find some Jupiter sized exoplanets 5 (+ 5 goal) years
PLATO 2024 (Soyuz-ST) It will discover and characterize rocky planets around stars like our own. 6 years
WFIRST Mid- 2020's Look for and study exoplanets while studying dark matter. 6 years
