NASA’s TESS is completing its main two-year mission. begins extended journey – Technology News, Firstpost



The Transiting Exoplanet Survey Satellite or TESS is one of the most powerful and successful spacecraft for the detection of exoplanets. After two years of extensive discovery, the vehicle has now reached the end of its main mission.

But since TESS has enough fuel, it already has began his extended missionNASA revealed in a statement on August 1

1th.

Patricia Boyd, the project scientist for TESS at NASA’s Goddard Space Flight Center, mentioned that TESS had been a successful company even before the extended service began.

“TESS produces a stream of high quality observations that provide valuable data on a wide variety of scientific topics,” she said.

During the transport, the ship managed to map about 75 percent of the sky from Earth. TESS had discovered 66 confirmed exoplanets During the main mission there are over 2100 celestial bodies waiting for confirmation from the astronomers.

It works in a very simple way – the satellite looks at a specific spot in the sky for a specific period of time and looks for breaks in the light of a star. If the dips occur at regular intervals, it means that a world or worlds are orbiting the star, thereby blocking its light at a certain point in time.

It had two years of operation as of July 2020 and presented scientists with 26 mosaic sectors depicting the northern and southern skies, as shown in this video. Each of the sectors consists of 24 x 96 degree strips of sky, which the TESS observed with its four cameras for a month.

The ship had spent its first year observing 13 sectors in the southern sky and then another year imaging the northern sky. On its extended mission, the vehicle has now focused on the southern sky again.
