NASA launched its new planet-hunter Transiting Exoplanet Survey Satellite or TESS from Cape Canaveral Air Force Station in Florida. The spacecraft is estimated about $337 million and it is of a washing machine-sized spacecraft. The main aim of the TESS is to search the nearer, brighter stars that have an Earth-like atmosphere.
TESS is about to search more than 200,000 brightest stars for the signs of the planets who are circling and cause a dip in brightness which is known as a transit. NASA predicted that the TESS will be covering about 200,000 exoplanets which are present outside of our solar system which includes more than 50 Earth-size planets and about 500 planets which care less than twice the size of the Earth.
NASA’s Kepler space telescope was launched during the year in 2009. The objective of the Kepler mission was to explore, how frequently planets occur around the stars. The Kepler mission already found about 2,300 confirmed exoplanets and about 4,500 candidates for future exoplanet research. TESS is also designed to search planets that are orbiting nearby stars which are spread across the sky. TESS is equipped with four advanced cameras, that will scan an area which is spread about 350 times more than the area that covers by TESS and it comprises about 85 percent of the sky during the first two years.
TESS is expected to search the stars that can be 30-100 times brighter and 10 times closer than the stars that Kepler has found.
According to the Elisha Quintana, who is the scientist at NASA’s Goddard Spaceflight Center told on Sunday that “ They are going to be orbiting the nearest brightest stars.” She added by saying that “ We might even find planets that orbit stars that we can even see with the naked eye.”
