Indian orbiter MOM still on lookout for methane on Mars

Mysuru (Karnataka): The Mars Orbiter Mission (MOM), India’s first interplanetary mission is still groping around the red planet to locate methane gas in its atmosphere, a senior space scientist said on Monday.

“The Mars Orbiter Mission (MOM) is yet to detect methane gas or find the exact source of it. I don’t have an update on how much of science we have been able to find out,” Indian space agency’s former director S.K. Shivakumar told IANS at the 103rd Indian Science Congress here.

Though India was the first country whose maiden space probe was the first to showcase stunning pictures of the red planet in its very first attempt on September 24, 2014, the 475kg orbiter with five scientific instruments on board is yet to relay substantial data or information on Mars’ origin and evolution in the solar system.

“Being a technology person, I don’t know what is its (MOM) current status,” he said on the sidelines of a plenary session on ‘Space Science, Technology, and Applications’, on the second day of the five-day annual event at Manasagangotri campus of University of Mysore.

The Rs.450-crore mission was launched on November 5, 2013, from spaceport Sriharikota in Andhra Pradesh, about 80km northeast of Chennai, and reached the Martian orbit after a 10-month voyage through the inter-planetary space.

“As of Sunday evening and Monday morning, the orbiter is doing well, going around Mars, taking a different set of pictures and whatever is required with its other payloads,” Shivakumar said.

The spacecraft was successful in surviving a solar eclipse and a 15-day blackout in June last year. It was under solar conjunction from June 8 after it went behind the sun and away from the earth due to a solar eclipse, which occurs once in 26 months over the red planet. The spacecraft is still elliptically orbiting around Mars even 28 months after it entered the Martian orbit.

“As the orbiter still has 37kg of fuel, it will continue to orbit around Mars as long as it can. Though built for six months, it is still alive and going on and on,” Shivakumar added.

Though the orbiter’s communication system was disrupted by the sun’s corona (outer atmosphere) during the fortnight-long eclipse, it got activated and its scientific instruments resumed their activities after being on autonomous mode.

Orbiter takes 3.2 earth days or 72 hours, 51 minutes and 51 seconds to go around Mars once while orbiting at a distance of 500 km nearest and over 80,000 km at the farthest from its surface. (IANS)

Curiosity Rover Completes 6 Years On Mars: NASA

Based on the longevity of a 2001 global storm, NASA scientists estimate it may be September before the haze has cleared enough for Opportunity to power up and call home.

NASA’s Curiosity rover is celebrating its sixth anniversary on Mars which is currently experiencing a global storm.

“I touched down on #Mars six years ago. Celebrating my 6th landing anniversary with the traditional gift of iron oxide. (It puts the red in Red Planet.),” said a tweet sent out by the rover on Sunday.

Curiosity, which landed on Mars in 2012, was designed to assess whether Mars ever had an environment able to support small life forms called microbes. In other words, its mission is to determine the planet’s “habitability.”

The rover is currently keeping its “eyes” on a dust event that had gone global by June 20.

Most of NASA’s spacecraft are studying the dust storm from above. But the Curiosity rover has a unique perspective: the nuclear-powered science machine is largely immune to the darkened skies, allowing it to collect science from within the beige veil enveloping the planet.

Curiosity has a number of “eyes” that can determine the abundance and size of dust particles based on how they scatter and absorb light, NASA said in a statement in July.

That includes its Mastcam, ChemCam, and an ultraviolet sensor on REMS, its suite of weather instruments.

NASA lost contact with its Opportunity rover due to the storm.
