NASA is set to launch the Transiting Exoplanet Survey Satellite (TESS) on Monday, starting a new chapter in the search for planets that could potentially support extraterrestrial life, AL Jazeera reports.
During its mission, TESS will analyse thousands of relatively nearby stars for planets orbiting the stars.
According to NASA, scientists expect to find about 50 Earth-sized planets and about 20,000 exoplanets in total, of which the vast majority will probably be larger than Neptune, our solar system's fourth biggest planet.
Exoplanets are planets that orbit a star other than the sun.
TESS will be sent into space aboard a SpaceX Falcon 9 rocket, the launch of which is slated to take place at 10:30 GMT at the Cape Canaveral station in Florida.
