Twilight

Pandora is a NASA Astrophysics Pioneers SmallSat mission, designed to observe at least twenty transiting exoplanets with a 0.45-metre telescope collecting simultaneous visible and near-infrared data. Its goal is to separate stellar contamination from true atmospheric absorption signatures, sharpening exoplanet composition measurements that depend on transit spectroscopy.
