NASA’s elite planet-hunting spacecraft has been declared dead, just a few months shy of its 10th anniversary.
Officials announced the Kepler Space Telescope’s demise Tuesday.
Already well past its expected lifetime, the 9½-year-old Kepler had been running low on fuel for months. Its ability to point at distant stars and identify possible alien worlds worsened dramatically at the beginning of October, but flight controllers still managed to retrieve its latest observations. The telescope has now gone silent, its fuel tank empty.
“Kepler opened the gate for mankind’s exploration of the cosmos,” said retired NASA scientist William Borucki, who led the original Kepler science team.
Super Earths found
Kepler discovered 2,681 planets outside our solar system and even more potential candidates. It showed us rocky worlds the size of Earth that, like Earth, might harbor life. It also unveiled incredible super Earths: planets bigger than Earth but smaller than Neptune.
NASA astrophysics director Paul Hertz estimated that anywhere from two to a dozen of the planets discovered by Kepler are rocky and Earth-sized in the so-called Goldilocks zone — the habitable area around a star where the temperature would permit existence of liquid water. But Kepler’s overall planet census showed that 20 percent to 50 percent of the stars visible in the night sky could have planets like ours in such a habitable zone for life, he said.
The $700 million mission even helped to uncover last year a solar system with eight planets, just like ours.
“It has revolutionized our understanding of our place in the cosmos,” Hertz said. “Now we know because of the Kepler Space Telescope and its science mission that planets are more common than stars in our galaxy.”
Almost lost in 2013 because of equipment failure, Kepler was salvaged by engineers and kept peering into the cosmos, thick with stars and galaxies, ever on the lookout for dips in in the brightness of stars that could indicate an orbiting planet.
“It was like trying to detect a flea crawling across a car headlight when the car was 100 miles away,” said Borucki said.
The resurrected mission became known as K2 and yielded 350 confirmed exoplanets, or planets orbiting other stars, on top of what the telescope had already uncovered since its March 7, 2009, launch from Cape Canaveral.
In all, close to 4,000 exoplanets have been confirmed over the past two decades, two-thirds of them thanks to Kepler.
Kepler focused on stars thousands of light-years away and, according to NASA, showed that statistically there’s at least one planet around every star in our Milky Way galaxy.
Borucki, who dreamed up the mission decades ago, said one of his favorite discoveries was Kepler 22b, a water planet bigger than Earth but in an area where it is not too warm and not too cold — the type “that could lead to life.”
A successor to Kepler launched in April, NASA’s Tess spacecraft, has its sights on stars closer to home. It’s already identified some possible planets.
Tess project scientist Padi Boyd called Kepler’s mission “stunningly successful.”
Kepler showed us that “we live in a galaxy that’s teeming with planets, and we’re ready to take the next step to explore those planets,” she said.
Another longtime spacecraft chasing strange worlds in our own solar system, meanwhile, is also close to death.
NASA’s 11-year-old Dawn spacecraft is pretty much out of fuel after orbiting the asteroid Vesta as well as the dwarf planet Ceres. It remains in orbit around Ceres, which, like Vesta, is in the asteroid belt between Mars and Jupiter.
Two of NASA’s older telescopes have been hit with equipment trouble recently, but have recovered. The 28-year-old Hubble Space Telescope resumed science observations last weekend, following a three-week shutdown. The 19-year-old Chandra X-ray Telescope’s pointing system also ran into trouble briefly in October. Both cases involved critical gyroscopes, needed to point the telescopes.
Hertz said all the spacecraft problems were “completely independent” and coincidental in timing.
Now 94 million miles from Earth, Kepler should remain in a safe, stable orbit around the sun. Flight controllers will disable the spacecraft’s transmitters, before bidding it a final “goodnight.” (VOA)
Sports betting has been around for centuries for the audience to not only watch the sport but to get more deeply involved in the match. It is a fun and often profitable activity for the viewer to win some extra fortune or simply get some extra sweat while watching the game.

It is indeed good news that the book showcasing the wisdom of India in the eyes of Western intellectuals is getting due recognition and appreciation from other states and abroad. After Karnataka and Punjab, the Government of Assam has recently consented to translate the research-based book by Shillong-based author - Shri Salil Gewali titled "Great Minds on India". The Chief Minister of Assam - Shri Himanta Biswa Sarma was amazed to know that so many top western scientists and philosophers have drawn a considerable amount of inspiration from ancient scriptures of India, particularly in the studies of modern physics, linguistic and astronomy. In the recent meeting with the author, the Chief Minister had highly appreciated Gewali's book and promised to read it thoroughly. Gewali's book was also approved for translation in the year 2020 by the former Chief Minister – Shri Sarbananda Sonowal but due to COVID-19, the translation work was delayed.

Furthermore, the two scholars from Canada --- Dr Hema Murty -- Air Space Engineer at the University of Toronto, and Dr. Harsh H Thakkar of Sheridan College of Brampton, Ontario have sought permission from Mr. Gewali for the translation of 'Great Minds on India' into the Sanskrit language. After the translation, the Sanskrit edition will be published and circulated and utilized by Samskrita Bharati of Canada, besides its other branches in India, USA and UK. Gewali says that the book that has been praised by countless scholars and publication by the Government of Karnataka and Punjab has so far been translated into thirteen languages, including German.
'Great Minds of India' by Salil Gewali is an impressive compact book discussing the power that Indian ancient wisdomFile
A university scholar from Winchester, United Kingdom - Ms. Janet Murphy remarks:
" 'Great Minds of India' by Salil Gewali is an impressive compact book discussing the power that Indian ancient wisdom, thought and way of life had an impact on western minds, especially those who are of great historical significance, such as Voltaire, Albert Einstein, Ralph Emerson, Julius Robert Oppenheimer, Mark Twain, HG Wells et al. It is hoped all right-thinking scholars will find Gewali's work extremely applaudable."
BEIJING — Chinese organizers have confirmed participants in next year's Winter Olympics will be strictly isolated from the general population and could face expulsion for violating COVID-19 restrictions.
Vice mayor and Beijing 2022 organizing committee official Zhang Jiandong told reporters Wednesday that those taking part in the games beginning Feb. 4 must remain in a "closed loop" for training, competing, transport, dining and accommodation.
A strict Olympic bubble has long been on the books, but Beijing has now made it official in keeping with its zero-tolerance approach to the pandemic. Athletes and other participants will also be tested regularly for the coronavirus before and during the Games. Family, spectators and sponsors from outside the country will not be allowed to attend.
"All participants of the Games and our Chinese staff and volunteers will implement the same policy," Zhang said. "They will be strictly separated from the external society.
"Those who do not comply with the epidemic prevention regulations may face severe consequences such as warning, temporary or permanent cancellation of registration, temporary or permanent disqualification or expulsion from the competition, and other punishment."
All participants must have been fully vaccinated at least 14 days prior to their departure for China.
China has enforced strict rules on mask wearing, quarantines and contact tracing that have largely succeeded in eliminating the local transmission of COVID-19, but imported cases and domestic infections continue to appear in daily reports.
"Indeed, epidemic prevention and control is the biggest challenge for us to host the Winter Olympic Games," Zhang told a news conference.
Wednesday marked 100 days until the Beijing Games. Organizers have held test events featuring international athletes at Olympic venues under strict conditions.
Japan imposed restrictive rules and an Olympic bubble during the July 23-Aug. 8 Summer Games in Tokyo, which had been postponed by 12 months because of the pandemic. (VOA/RN)
