Washington, April 12: NASA's Transiting Exoplanet Survey Satellite, or Tess aimed at detecting planets outside our solar system, is set to launch on a SpaceX Falcon 9 rocket from Florida on April 16.
The mission is scheduled to launch no earlier around 4.02 a.m. on April 17 (India time) from Cape Canaveral Air Force Station, NASA said on Wednesday.
Tess is NASA's next step in the search for exoplanets, including those that could support life.
Once in orbit, Tess will spend about two years surveying 200,000 of the brightest stars near the Sun to search for planets outside our solar system.
Tess will find the most promising exoplanets orbiting relatively nearby stars, giving future researchers a rich set of new targets for more comprehensive follow-up studies, including the potential to assess their capacity to harbour life.
With the help of a gravitational assist from the Moon, the spacecraft will settle into a 13.7-day orbit around Earth, NASA said in an earlier statement.
Sixty days after the launch and following tests of its instruments, the satellite will begin its initial two-year mission. Four wide-field cameras will give Tess a field-of-view that covers 85 per cent of our entire sky.
Within this vast visual perspective, the sky has been divided into 26 sectors that Tess will observe one by one.
The first year of observations will map the 13 sectors encompassing the southern sky, and the second year will map the 13 sectors of the northern sky.
The spacecraft will be looking for a phenomenon known as a transit, where a planet passes in front of its star, causing a periodic and regular dip in the star's brightness.
NASA's Kepler spacecraft used the same method to spot more than 2,600 confirmed exoplanets, most of them orbiting faint stars 300 to 3,000 light-years away

Man sets fire to gas cylinder on truck in Kerala's Kottayam, held
Kottayam(Kerala) (PTI): A 33-year-old man climbed onto a parked truck carrying cooking gas cylinders and set fire to one of them near Thalayolaparambu in the small hours of Saturday, police said.
