As part of NASA’s continued effort to ensure a steady supply of
astrophysics and astronomy missions, the agency is undertaking the
Astro2020: Decadal Survey on Astronomy and Astrophysics. Currently, in
the “Concept Study” phase, the survey includes proposals for four
large-scale space telescopes – including the Habitable Exoplanet
Observatory (HabEx).

HabEx would facilitate direct observation of exoplanets, carry a primary
focus on imaging Earth-like planets around Sun-like stars, and be able
to detect biomarkers or signs of possible life in those exoplanets’
atmospheres via spectroscopic observations.
