CAPE CANAVERAL, Fla.—A new NASA satellite designed to detect more Earth-like worlds around stars beyond our solar system is due for launch aboard a SpaceX rocket from Florida on Monday, on a quest to expand the known inventory of so-called exoplanets that might harbor life.
The Transit Exoplanet Survey Satellite, or TESS, was set to lift off from Cape Canaveral Air Force Station at 6:32 p.m. EDT, starting the clock on a two-year, $337 million mission in one of astronomy’s newest fields of exploration.
