NASA launches its newest planet-hunting spacecraft “TESS” to search for alien worlds

The National Aeronautics and Space Administration (NASA) has launched its newest planet-hunting spacecraft, Transit Exoplanet Survey Satellite (TESS) from Cape Canaveral in Florida on a mission to find thousands of new worlds beyond our Solar System. The mission will survey a great swathe of stars, hoping to catch the dips in brightness that occur when orbiting planets traverse their faces. TESS’s goal is to compile a catalogue that other telescopes can then focus in on for more detailed analysis. The mission’s Principal investigator from the Massachusetts Institute of Technology, George Ricker said, TESS is equipped with four very sensitive cameras that will enable it to monitor nearly the entire sky.
