Fast Infrared Exoplanet Spectroscopy Survey Explorer (FINESSE)
FINESSE provides uniquely detailed information and addresses many fundamental exoplanet science questions.
Operator NASA
Mission type Space observatory
Launch date 2017[1]
Mission duration 2 years

Fast Infrared Exoplanet Spectroscopy Survey Explorer (FINESSE) is a proposed NASA mission and space observatory in the explorer program consisting of a space telescope focused on studying the atmospheres of over 200 planets outside of our solar system with the goal of gaining understanding of the processes responsible for their composition, and how our solar system fits into the larger family of planets.

The principal investigator is Mark Swain of the Jet Propulsion Laboratory in Pasadena, California.[2] If chosen to go forward, FINESSE would launch in February 2017. The mission would last two years.
