Exoplanet Characterisation Observatory

Exploring the atmospheres of diverse worlds beyond our Solar System

Themes What are the conditions for planet formation and the emergence of life?
Primary goal To characterise the atmospheres of a diverse sample of nearby transiting exoplanets, including super Earths
Targets A sample of transiting exoplanets orbiting nearby F, G, K and M-type stars, covering a range of temperatures (250 Kelvin < T_equilibrium < a few 1000 Kelvin) and masses (few to 100s of Earth masses)
Wavelength Visible - thermal infrared (0.55 – 11 microns, with a goal to extend to 0.4 - 16 microns)
Telescope 1 metre class
Orbit Quasi halo orbit around the second Sun-Earth Lagrange point, L2
Lifetime 4 years
Type M-class candidate mission
