SpaceX’s Valuation Surges to $25 Billion With New Funding Round

The Tess satellite will survey nearly the entire sky, staring at the brightest, closest stars in an effort to find any planets that might be encircling them.

Nasa is poised to launch a $337 million washing machine-sized spacecraft that aims to vastly expand mankind's search for planets beyond our solar system, particularly closer, Earth-sized ones that might harbor life.

In this image released by SpaceX, NASA' s Transiting Exoplanet Survey Satellite (Tess) sits atop a SpaceX Falcon 9 rocket at Space Launch Complex 40, Monday, April 16, 2018, in Cape Canaveral, Fla.

The satellite is tasked with "a mission to detect planets outside of our solar system", NASA said on its website, referring to the so-called exoplanets.

The launch is now scheduled for Wednesday evening.

TESS's job is to spot distant planets when they pass in front of even more distant stars, a movement known to astronomers as a "transit".

"Tess will find small planets, rocky planets that might have atmospheres and features that may be conducive to life", Buzasi said.

"TESS is opening a door for a whole new kind of study", said Stephen Rinehart, TESS project scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland, which manages the mission.

"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". TESS will likely find exoplanets of a kind we've never seen before. Powerful cameras on TESS will monitor each section for at least 27 days at a time, looking at the brightest stars.

NASA says TESS could help answer the age-old question: Are we alone in the universe?
