NASA's Transiting Exoplanet Survey Satellite (TESS) is set to launch on a SpaceX Falcon 9 rocket.
The first stage of the Falcon 9 rocket consists of nine sea level adapted Merlin engines, where as the second stage only uses one vacuum adapted Merlin engine for delivery of the payload to a desired orbit.
According to reports, the satellite, which is aimed at finding far-away planets that could potentially support life, will be launched at 6:32 pm US Eastern Daylight Time (EDT) from the Cape Canaveral Air Force Station.
The satellite known as Tess will survey nearly the entire sky, staring at the brightest, closest stars in an effort to find any planets that might be encircling them.
"On average the stars that TESS observes are 30-100 times brighter and 10 times closer than the stars that Kepler focused on".More news: France convinced Trump to stay in Syria, says Macron
TESS is expected to "catalog thousands of planet candidates" and hugely raise the existing number of "known exoplanets", according to the NASA website.
Expecting the mission to span a minimum of two years, NASA expects TESS to survey 2,00,000 of the brightest stars outside our solar system to search for transiting exoplanets.
That said, it is worth noting TESS won't find life on any of these worlds. Once the planet has been identified, scientists will be able to take a close look from ground-based telescopes to confirm the discovery and determine how big the planet really is, what is the composition of its atmosphere and if it is a rocky or a gas giant, among many other things.
"TESS forms a bridge from what we have learned about exoplanets to date and where we are headed in the future", said Jeff Volosin, TESS project manager at NASA's Goddard Spaceflight Center.
