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 is plagued with a disease called Rape
  • There are no rigorous punishments for rape
  • Rapists openly commit crimes without anny fear

Why the clamour only for the rigorous punishment for rape and other sadistic crimes which have their roots in the mental-degeneration? Apart from the toughest punishment to the perpetrators, let’s go deeper to analyze what could be the possible  “causes”  that push men to commit rape. Why so much mental degeneration that certain individuals can stoop to the gutter being to their status, their position and social values? Well, how to address those issues is certainly a challenge. And that “challenge” certainly calls for a serious brain-storming and a serious self-assessment vise-a vise the environment in which we all are living.

True, in the physical world we are highly convinced brag about that healthy environment is a must for our healthy living. Even kids know these days that we can’t breathe well if our surroundings are filled with high levels of  “toxicity”. We have well studied through our academic textbooks that people invite the environmental disaster if they keep on allowing excessive emission of CO2, CO, methane and other dangerous gases into the atmosphere. We have fully acknowledged that each tall and black chimney of the industries and the nozzles of the motor vehicles are here only to mar the beauty of this planet? What kind of damages the toxic gases are doing to our ecosystem are not at all tough job to analyze with modern appliances. Again, a lot amount of books have been published to create the awareness, to inform us about the scientifically tested measures to resolve the environmental concerns.

However, do we have the same amount of literature that pinpoint the “causes” which contribute to turning “males into perverts”? Who else is emitting the “toxic substances” that overpower the inborn sensitivity of the deviant? What are the properties of toxic filth that is polluting the mind-scape of the society? Now we have Donald Trump, the president of the USA, whom many prefer call him a pervert. At this rate, the number perverts are increasing and they have become dangerously ubiquitous. And, all those perverts have brought nightmares to the ill-fated females. We often stage candle march in protest against the rape, but remain blind to the glaring “causes”. Should we still fiddle about and be appreciative of the society that shameless covers itself with the vulgarity — the “toxicity” that might numb the sanity of males? Watch out, dear friends, those perverts have begun to see even “baby girls” as objects of lust!

Please note:  what our sages said:  “What you see that you think, what you think that you do and what you do that become !!!!”

Again, I would like to draw another similarity with what prompt big people to “rape”/violate the harmony of the Mother Earth. The case is very regularly brought out by the conscious citizens across the country. A senior journalist Patricia Mukhim of Meghalaya has pointedly driven home recently how the “greed for money” has corrupted many leaders who are trying hard to justify the senseless exploitation of the “body” of Mother Earth. Many big shots of big companies struggle to convince the politicians to tweak the laws to grant the permission to perpetually “rape” the country.

In my mind, both are infected with common syndromes! While the one type is interested in the body of the females, the other type has a fetish for the rocky body of the “Mother Earth”. And which type is contributing more dangerously to the society can easily be measured with our simple plus and minus equation.

The rape victims are not getting the justice they deserve.

Let’s assess the issues from another angle, given the advancement of medical science. Till some years back malaria, dengue, cholera, HIV, smallpox were life-taking diseases. But the medical science has pretty successfully eradicated or contained them all. The scientists have correctly identified the causes of those dangerous diseases and recommended the remedial measures. No doubt, that is a very productive achievement. However, why have the modern studies practically failed to “identify the causes”  of the pandemic rise of the horrendous instances of rapes and criminality associated with them? Is it not a strong slap in the face of the modern civilization considering we have not yet spelt out the causes and the characteristic symptoms the  “toxic emitters” who turn decent males into sadists? How long will we endure the depravity which has already strangulated the decency of the society? Should we still wait to work out the tough laws? Should we still hitch to explore for the “causes” and remedial measures? I guess the time is ripe that each morally conscious individual be allowed a shotgun to shoot the “perversion and depravity” of any kind at sight!
