June 06, 2017: NASA has chosen 12 astronauts out of a record-breaking 18,300 applications for upcoming space missions. An American of Indian descent, Raja Chari, has successfully earned his spot in the top 12.

The astronauts were selected on the basis of expertise, education, and physical tests. This batch of 12 astronauts is the largest group selected by NASA since two decades. The group consisting of 7 men and 5 women surpassed the minimum requirements of NASA.

Born in Waterloo, Iowa, Chari graduated from Air Force Academy in 1999 with a bachelor’s degree in Astronautical Engineering and Engineering Science. He went on to complete his master’s in Aeronautics and Astronautics from Massachusetts Institute of Technology. The astronaut is also a graduate of US Naval Test Pilot School.

Currently, Raja Chari is a Lieutenant Colonel in the US Air Force. He is the commander of 461st Flight Test Squadron and director of the F-35 Integrated Test Force at Edwards Air Force Base in California.

After Late Kalpana Chawla, Lt. Col. Raja Chari is the second Indian American astronaut chosen by NASA.

The 12 astronauts will have to go through two years of training. Upon completion, they will be assigned their missions ranging from research at the International Space Station, launching from American soil on spacecraft by private companies, to flying on deep space missions on NASA’s Orion Spacecraft.

The US Vice-President Mike Pence visited the Johnson Space Centre in Houston to announce and congratulate the new batch. Pence also said that President Trump is “fully committed” to NASA’s missions in space.

NASA’s TESS Discovers New Worlds Only 5 Months After Its Launch

With four special cameras, TESS uses a detection method called transit photometry.

A planet-hunting orbital telescope designed to detect worlds beyond our solar system discovered two distant planets this week five months after its launch from Cape Canaveral, Florida, officials said on Thursday.

NASA’s Transiting Exoplanet Survey Satellite, better known as TESS, made an early discovery of “super-Earth” and “hot Earth” planets in solar systems at least 49 light-years away, marking the satellite’s first discovery since its April launch.

TESS is on a two-year, $337 million mission to expand astronomers’ known catalog of so-called exoplanets, worlds circling distant stars.

While the two planets are too hot to support life, TESS Deputy Science Director Sara Seager expects many more such discoveries.

“We will have to wait and see what else TESS discovers,” Seager told Reuters. “We do know that planets are out there, littering the night sky, just waiting to be found.”

TESS is designed to build on the work of its predecessor, the Kepler space telescope, which discovered the bulk of some 3,700 exoplanets documented during the past 20 years and is running out of fuel.

NASA expects to pinpoint thousands more previously unknown worlds, perhaps hundreds of them Earth-sized or “super Earth” sized — no larger than twice as big as our home planet.

Those are believed the most likely to feature rocky surfaces or oceans and are thus considered the best candidates for life to evolve. Scientists have said they hope TESS will ultimately help catalog at least 100 more rocky exoplanets for further study in what has become one of astronomy’s newest fields of exploration.

MIT researchers on Wednesday announced the discovery of Pi Mensae c, a “super-earth” planet 60 light-years away orbiting its sun every 6.3 days. The discovery of LHS 3844 b, a “hot-earth” planet 49 light-years away that orbits its sun every 11 hours, was announced on Thursday.

Pi Mensae c could have a solid surface or be a waterworld as the composition of such planets is a mixed bag, Martin Spill, NASA’s program scientist for TESS, said in a phone interview.

The two newest planets, which still need to be reviewed by other researchers, offer the chance for follow-up study, officials said.

“That, of course, is TESS’ entire purpose — to find those planets around those brightest nearby stars to do this really detailed characterization,” Spill said.

With four special cameras, TESS uses a detection method called transit photometry, which looks for periodic dips in the visible light of stars caused by planets passing, or transiting, in front of them. (VOA)
