Washing machine sized satellite to scan more than 200,000 stars for planets
TAMPA, UNITED STATES: 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.
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.
Its main goal over the next two years is to scan more than 200,000 of the brightest stars for signs of planets circling them and causing a dip in brightness known as a transit.
NASA predicts that TESS will discover 20,000 exoplanets -- or planets outside the solar system -- including more than 50 Earth-sized planets and up to 500 planets less than twice the size of Earth.
"They are going to be orbiting the nearest, brightest stars," Elisa Quintana, TESS scientist at NASA's Goddard Space Flight Center, told reporters on Sunday.
"We might even find planets that orbit stars that we can even see with the naked eye," she added.
"So in the next few years we might even be able to walk outside and point at a star and know that it has a planet. This is the future."
TESS is designed as a follow-on to the US space agency's Kepler spacecraft, which was the first of its kind and launched in 2009. Now, the aging spacecraft is low on fuel and near the end of its life.
Kepler found a massive trove of exoplanets by focusing on one patch of sky, which contained about 150,000 stars like the Sun.
The Kepler mission found 2,300 confirmed exoplanets and nearly 4,500 candidates. But many were too distant and dim to study further.
TESS, with its four advanced cameras, will scan an area that is 350 times larger, comprising 85 percent of the sky in the first two years alone.
"By looking at such a large section of the sky -- this kind of stellar real estate -- we open up the ability to cherry-pick the best stars to do follow up science," said Jenn Burt, a postdoctoral fellow at the Massachusetts Institute of Technology (MIT).
"On average the stars that TESS finds observes be 30-100 times brighter and 10 times closer than the stars that Kepler focused on."
Since TESS uses the same method as Kepler for finding potential planets, by tracking the dimming of light when a celestial body passes in front of a star, the next step is for ground-based and space telescopes to peer closer.
The Hubble Space Telescope and the James Webb Space telescope, scheduled to launch in 2020, should be able to reveal more about planets' mass, density and the makeup of their atmosphere.
"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 Space Flight Center.
By focusing on planets dozens to hundreds of light-years way, TESS should be a stepping stone to future breakthroughs, he said.
"With the hope that someday, in the next decades, we will be able to identify the potential for life to exist outside the solar system."
Weather was expected to be 80 percent favorable for launch.

Karnataka Milk Federation enters Delhi-NCR, offers competitive pricing on Nandini products
New Delhi, Nov 21: Karnataka Chief Minister Siddaramaiah on Thursday launched the Karnataka Milk Federation's (KMF) Nandini brand milk products in the Delhi-NCR market, pricing them marginally lower than competitors to gain a foothold in the region.
The cooperative will retail four cow milk variants, curd, and buttermilk from Friday, with competitive pricing that undercuts established players like Mother Dairy and Amul.
Cow milk will be sold at Rs 56 per litre, full Cream Milk at Rs 67 per litre, Standardised Milk at Rs 61 per litre, Toned Milk at Rs 55 per litre, and curd at Rs 74 per kg.
"We have surplus milk in the state. KMF along with Mandya Milk Union will market surplus milk of 3-4 lakh litres per day in Delhi-NCR," Siddaramaiah told reporters after launching the products.
The federation currently collects 100 lakh litres of milk daily, with local consumption at 60 lakh litres, leaving a surplus of 40 lakh litres for expansion into new markets.
However, the Chief Minister acknowledged the challenges of transporting milk over 2,500 km, which takes 50-54 hours.
There is a need to find new markets for surplus milk and gradually the KMF should be able to sell 5-6 lakh litres per day in Delhi-NCR, he added.
KMF Chairman LBP Bheemanaik assured that milk quality would be maintained during transit.
The federation has already partnered with 40 dealers in the Delhi-NCR region to facilitate sales, he added.
With a robust infrastructure of 26.76 lakh milk producers, 15,737 dairy cooperative societies, and 15 district milk unions, KMF has a turnover of Rs 25,000 crore and exports dairy products to over 25 countries.
State Animal Husbandry Minister K Venkatesh and Agriculture Minister N Cheluvarayaswamy were present at the product launch.
ದೇಶದ ಹಾಲು ಉತ್ಪಾದನೆಯಲ್ಲಿ ಗುಜರಾತ್ ಮೊದಲ ಸ್ಥಾನದಲ್ಲಿದ್ದರೆ, ಕರ್ನಾಟಕ ಎರಡನೇ ಸ್ಥಾನದಲ್ಲಿದೆ.
