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)

NASA’s plan on getting Martian samples to Earth

  • NASA plans on getting Martian samples to Earth from Mars
  • To know if life existed anywhere other than on Earth

Washington, Dec 11: (IANS) NASA has revealed how it plans to bring back Martian samples to Earth for the first time with the help of its next rover mission to the Red Planet, Mars 2020.

After landing on Mars, a drill will capture rock cores, while a caching system with a miniature robotic arm will seal up these samples. Then, they will be deposited on the Martian surface for possible pickup by a future mission, NASA said.

“Whether life ever existed beyond Earth is one of the grand questions humans seek to answer,” said Ken Farley of NASA’s Jet Propulsion Laboratory in Pasadena, California.

“What we learn from the samples collected during this mission has the potential to address whether we’re alone in the universe,” Farley said.

Mars 2020 relies heavily on the system designs and spare hardware previously created for Mars Science Laboratory’s Curiosity rover, which landed in 2012.

Despite its similarities to Mars Science Laboratory, the new mission has very different goals – it will seek signs of ancient life by studying the terrain that is now inhospitable, but once held flowing rivers and lakes, more than 3.5 billion years ago.

To achieve these new goals, the rover has a suite of cutting-edge science instruments.

It will seek out biosignatures on a microbial scale.

An X-ray spectrometer will target spots as small as a grain of table salt, while an ultraviolet laser will detect the “glow” from excited rings of carbon atoms.

A ground-penetrating radar will look under the surface of Mars, mapping layers of rock, water and ice up to 10 metres deep, depending on the material.

The rover is getting some upgraded Curiosity hardware, including colour cameras, a zoom lens and a laser that can vaporise rocks and soil to analyse their chemistry, NASA said.

The mission will also undertake a marathon sample hunt.

The rover team will try to drill at least 20 rock cores, and possibly as many as 30 or 40, for possible future return to Earth, NASA said.

Site selection has been another milestone for the mission. In February, the science community narrowed the list of potential landing sites from eight to three.

All three sites have rich geology and may potentially harbour signs of past microbial life. But a final landing site decision is still more than a year away.

“In the coming years, the 2020 science team will be weighing the advantages and disadvantages of each of these sites,” Farley said.

“It is by far the most important decision we have ahead of us,” Farley said.

The mission is set to launch in July/August 2020. (IANS)

  • Sequel to 1987 Classic Mr. India will be featuring Sridevi and Jhanvi Kapoor.
  • Mr.India 2 will be directed by the director of MOM, Ravi Udyawar.

Mr. India 2 will be the first movie of Mother-Daughter duo Sridevi and Jhanvi Kapoor

Mr. India became one of the biggest hits of Bollywood. Sridevi and Anil Kapoor romancing as leads left the audience awestruck in 1987. According to some reports, Mother-Daughter duo Sridevi and Jhanvi Kapoor will be sharing space in the sequel of Mr.India.

Director of the movie ‘Mom’, Ravi Udyawar will be directing the sequel and he stated the movie will be having two lead pairs, one will be of Anil Kapoor and Sridevi and other will likely to have Jhanvi as the female actress.

However none of them has given any official statement about their roles, but if turned to be right then it will be interesting to see Sridevi and Jhanvi together on screen.

Mission Mars: Red Planet Mars possess ‘Ideal Conditions’ to create Oxygen from Natural Carbon Dioxide, says Study

London, Oct 23: A study has found Mars to attain near ideal conditions for dynamically creating oxygen from atmospheric carbon dioxide with the use of plasma technology.

As stated by researchers from the University of Porto in Portugal and Ecole Polytechnique in Paris, Mars is already comprised of 96 per cent CO2 (carbon dioxide) in its atmosphere.

The PTI reported the research published in the journal Plasma Sources Science and Technology depicting the pressure and temperature ranges in the Martian atmosphere that sustains non-thermal plasma useful for effective production of oxygen.

Vaso Guerra, a researcher from the University of Lisbon in Portugal put forth his statement about their next significant steps of sending a manned mission to Mars for exploration of space. They are planning to create a substantial change by creating a breathable environment on Mars.

Plasma reforming of CO2 on Earth is an advancing research study, stimulated by the problems of change in climate and production of solar fuels. Plasmas at low temperature are one of the best media for CO2 deformation, where the molecule splits into oxygen and carbon monoxide combined with direct electron impact, and transfer of electron into vibrational energy.

Mars has superficial conditions for In-Situ Resource Utilisation (ISRU) through the plasma.

The cold atmosphere may stimulate high vibrational effect for producing oxygen than that achievable on Earth. The low atmospheric temperature on Mars will also enable the reaction to be slowly giving the maximum amount of time for separation of molecules.

The plasma technology decomposition method aims to offer a two output for a manned mission towards Mars. The technique would provide a stable supply of oxygen and as a source of fuel that can be used as a propellant mixture in rocket vehicles. This approach by ISRU could help in simplifying the logistics involved in space exploration by increasing self-sufficiency, decrease the risks to the crew, and reduction in expenditure for carrying out the mission.
