The seven members of the Expedition 73 crew worked on science and station keeping activities during their week together aboard the International Space Station.
As missions like Kepler and TESS discovered more rocky exoplanets in recent years, scientists looked forward to the launch of the JWST. The powerful space telescope has the ability gather infrared spectra of exoplanet atmospheres, a key need in understanding the planets being discovered. It was hoped that these atmospheric characterizations would advance our understanding of habitability.
