Live Stream Launch of NASA' TESS Planet Hunter Today

On the hunt for Earth 2.0: Watch NASA's TESS launch live

The launch of NASA's TESS spacecraft, planned for launch Monday afternoon, has been delayed until Wednesday, SpaceX and NASA officials said.

The Transiting Exoplanet Survey Satellite, or TESS, is scheduled to launch Monday at 6:32 pm (2232 GMT) atop a SpaceX Falcon 9 rocket from Cape Canaveral, Florida.

"Launch teams are standing down today to conduct additional Guidance Navigation and Control analysis".

A SpaceX rocket is scheduled to blast off with Tess at 6:32pm local time.

TESS will survey the entire sky over the course of two years by breaking it up into 26 different sectors, each 24 degrees by 96 degrees across.

The mysterious worlds beyond our solar system, called exoplanets, could harbour life.

It is said that once TESS takes off, it will arrive in the orbit of the earth and will move in the highly elliptical path which will bring it closer to the moon.

The TESS launch will mark a new milestone in space exploration as it replaces one of NASA's most powerful space telescopes: the Kepler space telescope which is nearing the end of its mission. Sixty days after the launch and following tests of its instruments, the satellite will begin its initial two-year mission. Meanwhile, SpaceX will stay busy with some important launches like the debut of its "Block 5" Falcon 9 rocket.

"That is about 20 times what the Kepler mission was able to detect", George Ricker, TESS principal investigator at MIT, said in a statement.

"But it's not just quantity; it's quality as well - because the planets we do find will be bright enough and close enough to Earth that we really can do follow-up measurements with them".

TESS is a scientific exploration to find exoplanets - worlds which orbit other stars - amongst 200,000 stars.

But the goal is to identify stars hosting relatively small, rocky Earth-like planets orbiting in the habitable zones of their suns at distances that allow water to exist as a liquid, a requirement for life as it is known on Earth.

"But since then, we have found thousands of planets orbiting others stars and we think all the stars in our galaxy must have their own family of planets".

"One of the many incredible things that Kepler told us is that planets are everywhere and there are all kinds of planets out there". For ages, they have wondered and worked hard for finding new life on a different planet. It also used the "transit technique" to confirm more than 2,000 so-called exoplanets.
