New York, July 30, 2017: A small asteroid that is expected to fly close to the Earth in October will help NASA to test its network of observatories, a group of NASA researchers, including an Indian-origin scientist, has said.

The flyby would also benefit scientists who work with planetary defence.

According to a press statement on NASA’s website earlier this week, the target of all this attention is asteroid 2012 TC4 — a small asteroid estimated to be between 10 and 30 metres in size.

Asteroid TC4 will safely fly past the Earth on October 12, and scientists are certain it will come no closer than 6,800 km from the surface of the Earth.

The asteroid has been out of range of telescopes since 2012 when it sped past the Earth at about one-fourth the distance from the Earth to the Moon.

For Indian-origin scientist Vishnu Reddy, this is an opportunity for the collaborative observation campaign to utilize the international aspect of the network.

“This is a team effort that involves more than a dozen observatories, universities, and labs across the globe so we can collectively learn the strengths and limitations of our near-Earth object observation capabilities,” said Reddy, Professor at the University of Arizona.

Scientists believe that asteroid 2012 TC4 may be slightly larger than the space rock that hit the Earth’s atmosphere near Chelyabinsk, Russia, in February 2013.

NASA will use large telescopes to detect and re-establish the asteroid’s precise trajectory. The new observations are expected to help refine knowledge about its orbit, narrowing the uncertainty about how far it will be from the Earth at its closest approach in October.

“Scientists have always appreciated knowing when an asteroid will make a close approach to and safely pass the Earth because they can make preparations to collect data to characterize and learn as much as possible about it,” said Michael Kelley, Programme Scientist and NASA Headquarters lead for the TC4 observation campaign.

“This time, we are adding in another layer of effort, using this asteroid flyby to test the worldwide asteroid detection and tracking network, assessing our capability to work together in response to finding a potential real asteroid threat,” Kelley added.

Scientists from NASA’s Centre for Near-Earth Object Studies (CNEOS) at the Jet Propulsion Laboratory (JPL) in California, have determined that while at closest approach, asteroid 2012 TC4 will pass no closer than 6,800 km from the Earth — it will more likely pass much farther away, as far as 270,000 km, or two-thirds of the distance from the Earth to the Moon.

Mars Rover’s Mission Now Over, Confirms NASA

Opportunity landed on Mars on January 24, 2004. First among the mission’s scientific goals was to search for and characterise a wide range of rocks and soils for clues to past water activity on Mars

NASA has announced the end of its Opportunity rover’s mission, 15 years after its arrival on Mars.

The announcement was made on Wednesday at a press conference at the agency’s Jet Propulsion Laboratory in Pasadena, California, following NASA’s last attempt to communicate with the rover on Tuesday night which got no response, Xinhua reported.

The rover last communicated with Earth on June 10, 2018, as a planet-wide dust storm blanketed the solar-powered rover’s location on Mars. It has not been heard from for eight months since then.

Opportunity likely experienced a low-power fault, a mission clock fault and an up-loss timer fault, according to the mission team.

Team members have tried to rouse the rover ever since, and radiated more than a thousand commands to restore contact. However, no signal was heard from again.

“Saying goodbye is hard, but it comes the time,” said John Callas, project manager for Opportunity.

“It is because of trailblazing missions such as Opportunity that there will come a day when our brave astronauts walk on the surface of Mars,” said NASA Administrator Jim Bridenstine.

“When that day arrives, some portion of that first footprint will be owned by the men and women of Opportunity, and a little rover that defied the odds and did so much in the name of exploration,” he said.

The golf-cart-sized rover far exceeded its planned 90-day mission lifetimes. It has worked for nearly 15 years and travelled over 45 km by the time it reached its most appropriate final resting spot on Mars — Perseverance Valley.
