SpaceX has launched NASA's planet-hunting satellite TESS into outer space Wednesday evening from Cape Canaveral.
Tess — short for Transiting Exoplanet Survey Satellite — will spend two years searching for planets near bright, nearby stars. The satellite was launched on a SpaceX Falcon 9 rocket.
The launch window was narrow — just 30 seconds — and TESS was to be deployed into orbit about 48 minutes after launch.
