Scientists find Mars surface replica in India

Kolkata: Why wait for a million-dollar ticket to Mars when you can have an inter-planetary experience a la Oscar nominated blockbuster “The Martian” right here in India?

One simply needs to head over to the western Indian state of Gujarat to glimpse the remarkable rocky landscape similar to the Red planet.

A replica or “terrestrial analogue” of the Martian surface has been discovered in the state, thanks to Indian scientists from the Space Applications Centre (SAC-ISRO) in Ahmedabad, Indian Institute of Technology-Kharagpur and the National Geophysical Research Institute (NGRI) in Hyderabad.

The team identified and documented the presence of a rare mineral jarosite through spectroscopic studies in Matanumadh area (86 km northwest of Bhuj) in Kachch district of Gujarat, a finding which links it to the Red planet. This work is part of a programme initiated by SAC-ISRO under its Mars mission.

“The landscape of Matanumadh with its unusual mineral assemblage, including jarosite, in a basalt terrain, mimics the geological environment of many of the identified jarosite localities on Mars,” Saibal Gupta, professor in Department of Geology and Geophysics at IIT-Kharagpur, told reporters.

Presence of the rare mineral was reported from various parts of the surface of the Red planet by NASA’s Mars exploration rover Opportunity in 2004. Since then, other rovers have detected jarosite at several localities on the planet’s surface.

The fact that jarosite is found in limited natural terrestrial environments means “extreme and unusual” conditions are required for its formation and stabilisation.

“The Martian surface must, at some time, have experienced these conditions. Thus, the positive identification of jarosite, in addition to the previously reported minerals natroalunite and minamiite, is a major argument in favour of the Matanumadh Formation representing a Martian analog locality,” contended Souvik Mitra, of IIT-Kharagpur.

In fact, as a clone, the Indian site more closely resembles the Martian surface than known Western Australian jarosite localites, note the researchers in the study published in the Journal ofGeophysical Research: Planets in March.

The significance of the discovery is multi-fold and could have implications in the way we explore the Martian surface.

NASA is working to send humans to Mars in the 2030s, but there are many milestones to accomplish to ensure that astronauts come back to the Earth safely, the space agency says on its website.

“The two essential conditions for jarosite formation are near-surface acidic water and oxidizing conditions. Understanding how jarosite formed in the Matanumadh Formation may shed light on the final stages of aqueous (water-based) activity in parts of the Martian surface,” said Mitra. Last year, NASA scientists found evidence of flowing water on Mars.

Mitra envisages if the local tourism authorities can educate the locals about the site and its link to Mars, then it could also benefit regional tourism.

Most importantly, in addition to sending up sophisticated robots and probes on Mars to study it, investigations could be carried out right at the Matanumadh Formation at a reduced cost, to understand what transpired on Mars a few billion years ago, according to Gupta.

“This is no substitute to human exploration of the Martian surface, but that could be quite some time in the future. Till then, these analog localities provide a starting point for knowing what to expect.”

“In fact, this work is a demonstration of what collaboration between scientists from different organisations within India can do, and SAC-ISRO is to be commended for this endeavour,” Gupta added. (IANS)

  • India successfully tests the Agni-V ballistic missile on Thursday
  • This was the fifth test that missile underwent
  • With this success India is now in ranks with US, UK, China and Russia

India on Thursday successfully test fired its indigenously developed intercontinental surface-to-surface nuclear-capable ballistic missile Agni-V — the most potent and with the longest range in the Agni series – that can reach targets as far as Beijing.

The test took place at the Abdul Kalam Island facility off the Odisha coast. Defence Minister Nirmala Sitharaman tweeted about its success, congratulating its makers DRDO, the armed forces and the defence industry.

She said the successful test of the 5,000-km-range missile that can carry a one-tonne warhead, was “a major boost to the defence capabilities of our country”.

“The Made in India canistered missile, having three stages of propulsion, was successfully test fired,” she tweeted.

Developed by the Defence Research and Development Organisation (DRDO), the Agni-V is the most advanced version of the Agni series, part of the Integrated Guided Missile Development Programme that started in the 1960s.

The missile was earlier tested successfully in 2012, 2013, 2015 and 2016.

This was the fifth test of the missile and likely to be its first user trial, though there was no official word on it.

Thursday’s test brings the missile closer to its induction in the tri-service Strategic Forces Command.

The missile has a much longer shelf life, with its container being made of special steel that absorbs the blast of the takeoff.

In the canisterised launch, a gas generator inside ejects the missile up to a height of about 30 metres. A motor is then ignited to fire the missile.
