Nasa all set to launch new planet hunting mission TESS

The launch of NASA's Transiting Exoplanet Survey Satellite (TESS) has been delayed for at least 48 hours because of a technical problem with the SpaceX Falcon 90 rocket that is supposed to send it into space.

Barely 2 hours before the launch of SpaceX's Falcon 9 rocket on Monday carrying NASA's new space telescope created to detect worlds beyond our solar system, the planned launch had to be delayed for at least 48 hours due to a technical glitch.

NASA Scientists believe they will find some giant planets, like Jupiter, but will also find planets that are similar in size to Earth. TESS will spend two years scanning almost the entire sky-a field of view that can encompass more than 20 million stars.

At a total cost of $337 million, the washing-machine-size spacecraft is built to search the nearest, brightest stars for signs of periodic dimming.

The name Tess is short for Transiting Exoplanet Survey Satellite.

"TESS is going to dramatically increase the number of planets that we have to study", said Ricker.

NASA has assured everyone that TESS is fine, so don't worry.

TESS and Kepler use the same system of detecting planetary transits, or shadows cast as they pass in front of their star.

"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". "Looking at how long it takes a planet to orbit its star, scientists are able to determine the shape of the planet's orbit and how long it takes the planet to circle its sun".

NASA's TESS mission hopes to find exoplanets beyond our solar system. "Those small stars will produce the biggest signals, and we have to start somewhere", says Angus, who remains hopeful about what could be found.

But TESS will scan a broader swath of the heavens to focus on 200,000 pre-selected stars that are relatively nearby - some of them just dozens of light years away - and thus among the brightest as seen from Earth. In addition, we can form a picture of what the inside of a star looks like.

This highly-elliptical orbit will help maximize TESS's field of vision, making it possible for the satellite's four cameras to image up to 85 percent of the sky. "TESS is kind of like a scout", said Natalia Guerrero, deputy manager of TESS Objects of Interest, an MIT-led effort that will catalogue objects captured in TESS data that may be potential exoplanets.
