NASA's newest planet hunter starts science operations
Washington, July 29 : After a successful launch in April this year, NASA's newest planet hunter, the Transiting Exoplanet Survey Satellite (TESS), has now started its search for planets around nearby stars.
Officially beginning science operations on July 25, TESS is expected to transmit its first series of science data back to Earth in August, and thereafter periodically every 13.5 days, once per orbit, as the spacecraft makes it closest approach to Earth, NASA said in a statement.
"I'm thrilled that our new planet hunter mission is ready to start scouring our solar system's neighborhood for new worlds," said NASA Astrophysics Division Director Paul Hertz.
"Now that we know there are more planets than stars in our universe, I look forward to the strange, fantastic worlds we're bound to discover," Hertz added.
TESS is NASA's latest satellite to search for planets outside our solar system, known as exoplanets. The mission will spend the next two years monitoring the nearest and brightest stars for periodic dips in their light.
These events, called transits, suggest that a planet may be passing in front of its star. TESS is expected to find thousands of planets using this method, some of which could potentially support life.

Rupee hits all-time low for second time in a week
Mumbai (PTI): The rupee depreciated 31 paise to settle at 91.99 against the US dollar on Wednesday, touching the lowest closing level for the second time in less than a week, amid increased month-end demand for the greenback.
Forex traders said the rupee opened higher as the US dollar index softened and a long-awaited trade breakthrough with Europe offered quiet reassurance. However, increased month-end demand for the American currency as well as the ongoing geopolitical tensions dented investors' sentiments.
At the interbank foreign exchange, the rupee opened at 91.60 and touched an early high of 91.50, but pared all the gains to touch an intra-day low of 91.99 against the greenback.
The domestic unit settled 31 paise down, revisiting its lowest-ever closing level of 91.99 against the greenback. The Indian currency previously ended at this level on January 23 when it also hit its all-time intraday low of 92 against the US dollar.
On Tuesday, the rupee rebounded from its all-time low levels and gained 22 paise to close at 91.68 against the US dollar.
Analysts said the rupee opened higher as the US dollar index softened and a long-awaited trade breakthrough with Europe bolstered investor sentiment.
India and the European Union on Tuesday announced the conclusion of negotiations for the free trade agreement (FTA), under which a number of domestic sectors such as apparel, chemicals and footwear will get duty-free entry into the 27-nation bloc, while the EU will get access to the Indian market at concessional duty for cars and wines, an official said.
The deal has been dubbed the "mother of all deals" as it will create a market of about 2 billion people.
Meanwhile, the dollar index, which gauges the greenback's strength against a basket of six currencies, was trading 0.07 per cent lower at 96.14.
Brent crude, the global oil benchmark, was trading 0.43 per cent lower at USD 67.28 per barrel in futures trade.
On the domestic equity market front, Sensex jumped 487.20 points to settle at 82,344.68, while Nifty surged 167.35 points to 25,342.75.
Foreign Institutional Investors turned net buyers and purchased equities worth Rs 480.26 crore on Wednesday, according to exchange data.
