(MULTI) – IATE term of the week: satellite TermCoord


The Transiting Exoplanet Survey Satellite (TESS) was launched on 18 April on a mission to survey stars and discover thousands of new worlds beyond our solar system. TESS now takes over from Kepler – the previous satellite. This space telescope, equipped with four cameras, will scan almost the entire sky for at least two years, focusing its objectives on the nearest and brightest stars. Thus 85% of the sky will be photographed and analysed. Its goal is to find and identify exoplanets ranging from Earth-sized to gas giants, orbiting a wide range of stellar types and orbital distances. Hundreds of thousands of stars will be scanned, with the hope that many exoplanets will be revealed in our cosmic backyard. The primary goal of the mission is to detect small planets in the solar region, so that detailed accounts of the planets and their atmospheres can be performed.

“The sky will become more beautiful, more impressive. We are thrilled TESS is on its way to help us discover worlds we have yet to imagine, worlds that could possibly be habitable, or harbour life,” notes NASA’s highest scientific administrator, Thomas Zurbuchen. The discoveries of TESS and other missions, he said, will bring us closer to answering the questions we have been asking ourselves for thousands of years: does life exist elsewhere in the Universe? If so, is this life microbial, or more advanced? Once TESS has identified new planets, terrestrial and space telescopes will be able to study them more accurately. Before the Kepler telescope was launched, no one knew if exoplanets were rare or …
