India, US must collaborate more on space research, says NASA scientist

January 22, 2017

New Delhi, Jan 22: India and the US should collaborate more on space research programmes, a prominent scientist from the US space agency NASA stressed here as he felicitated two young Indian astronomers who created history by discovering asteroids in 2010 that are now recognised by the International Astronomical Union (IAU) in the US.

Amanjot Singh and Sahil Wadhwa, former students of Ryan International School in Rohini, were part of the All India Asteroid Search Campaign (AIASC) conducted by New Delhi-based Science Popularisation Association of Communicators and Educators (SPACE) organisation in collaboration with the International Astronomical Search Collaboration, where they discovered the main belt asteroid numbered as 2010 PO24.

“India and the US should collaborate on such research programmes. NASA is looking forward to invite students from across the globe to participate in their space outreach programmes,” Paul Rosen, Project Scientist, NASA-ISRO Synthetic Aperture Radar from NASA Jet Propulsion Laboratory (JPL), said.

“What started as an excuse for night-out with friends became a passion. It is this passion that helped me succeed,” added Singh at the annual meet organised by SPACE which is working to make science and astronomy popular among youngsters in India.

In the asteroid search campaign, students from across the country were able to discover nearly 500 new rocks in space. However, these remained preliminary discoveries as they appeared to be asteroids but did not get confirmed because they tend to move away from their orbits. But, when the discovered asteroids remain in their orbits, it is named as a provisional discovery.

“Out of the 37 asteroids discovered (provisional discovery) worldwide in 2016, 27 have been by Indian students,” Sachin Bahmba, Chairman and Managing Director-SPACE Group said.

The annual meet was also addressed by former SPACE achievers who stressed on the need for research platforms and opportunities for children across the country to excel in astronomy and science and technology.

“Curiosity to explore the unknown and an opportunity provided by SPACE led me to the field of astronomy,” Aryan Mishra, a 17-year-old astronomer who discovered an asteroid in 2014, said.
“For children living in a developing country like India, it is not easy to dream about space and the field of astronomy. However, it is my endeavour to change the mindset of people towards this field,” added Mishra.

“Do not end your doubt with nothing. Try to find out as it may lead to a huge discovery one day,” said 17-year-old Yashraj Bhardwaj. Bhardwaj, who along with his twin brother Yuvraj, is the winner of Karamveer Chakra Award. The two have 22 projects — national and international — as well as seven patents to their names.

Through various astronomy-based outreach programmes, SPACE has managed to touch base with more than one lakh families and have educated more than 20,000 students annually, Bahmba informed. “We look forward to fruitful Indo-US ties, which can come up with new technological advancements through researches done by amateurs and the scientific community of both the countries,” he said.

Washington, Jan 7: Facebook will ban deepfake videos ahead of the US elections but the new policy will still allow heavily edited clips so long as they are parody or satire, the social media giant said Tuesday.

Deepfake videos are hyper-realistic doctored clips made using artificial intelligence or programs that have been designed to accurately fake real human movements.

In a blog published following a Washington Post report, Facebook said it would begin removing clips that were edited--beyond for clarity and quality--in ways that "aren't apparent to an average person" and could mislead people.

Clips would be removed if they were "the product of artificial intelligence or machine learning that merges, replaces or superimposes content onto a video, making it appear to be authentic," the statement from Facebook vice-president Monika Bickert said.

However, the statement added: "This policy does not extend to content that is parody or satire, or video that has been edited solely to omit or change the order of words."

US media noted the new guidelines would not cover videos such as the 2019 viral clip -- which was not a deepfake -- of House Speaker Nancy Pelosi that appeared to show her slurring her words.

Facebook also gave no indication on the number of people assigned to identify and take down the offending videos, but said videos failing to meet its usual guidelines would be removed, and those flagged clips would be reviewed by teams of third-party fact-checkers -- among them AFP.

The news agency has been paid by the social media giant to fact-check posts across 30 countries and 10 languages as part of a program starting in December 2016, and including more than 60 organisations.

Content labeled "false" is not always removed from newsfeeds but is downgraded so fewer people see it -- alongside a warning explaining why the post is misleading.

The Mars Colour Camera (MCC) onboard ISRO's Mars Orbiter Mission has captured the image of Phobos, the closest and biggest moon of Mars.

The image was taken on July 1 when MOM was about 7,200 km from Mars and 4,200 km from Phobos.

"Spatial resolution of the image is 210 m.

This is a composite image generated from 6 MCC frames and has been color corrected," ISRO said in an update along with the image.

Phobos is largely believed to be made up of carbonaceous chondrites.

According to ISRO, "the violent phase that Phobos has encountered is seen in the large section gouged out from a past collision (Stickney crater) and bouncing ejecta."

"Stickney, the largest crater on Phobos along with the other craters (Shklovsky, Roche & Grildrig) are also seen in this image," it said.

The mission also known as Mangalyaan was initially meant to last six months, but subsequently ISRO had said it had enough fuel for it to last "many years."

The country had on September 24, 2014 successfully placed the Mars Orbiter Mission spacecraft in orbit around the red planet, in its very first attempt, thus breaking into an elite club.

ISRO had launched the spacecraft on its nine-month- long odyssey on a homegrown PSLV rocket from Sriharikota in Andhra Pradesh on November 5, 2013.

It had escaped the earth's gravitational field on December 1, 2013.

The Rs 450-crore MOM mission aims at studying the Martian surface and mineral composition as well as scan its atmosphere for methane (an indicator of life on Mars).

The Mars Orbiter has five scientific instruments - Lyman Alpha Photometer (LAP), Methane Sensor for Mars (MSM), Mars Exospheric Neutral Composition Analyser (MENCA), Mars Colour Camera (MCC) and Thermal Infrared Imaging Spectrometer
