Is Life Possible on Mars? Study by Indian Scientists Offers Hope to Humanity

New Delhi: Research conducted by Indian scientists has offered the world significant hope in the quest to unravel some of the unsolved mysteries associated with space. The launch of the 'Aryabhata' satellite in 1975 marked, in essence, India's emphatic knock at the door of space. Since then, India has not only successfully launched its own satellites into space but has also placed satellites belonging to numerous countries across the globe into orbit.

Subsequently, in 2013, by successfully placing the 'Mangalyaan' spacecraft into Mars' orbit on its very first attempt, India demonstrated that it has no peer in the field of space science. However, does life exist on Mars? The answer to this question remains elusive. Now, in pursuit of this very answer, Dr. Ram Karan—an Associate Professor in the Department of Microbiology at the South Campus of the University of Delhi—along with his research students, Shubham Pandey, Anjali Gupta, and Ashwini Chauhan, has made a significant discovery.

Did They Conduct Research on Microorganisms in Antarctica's Deep Lake?

This research by Dr. Ram Karan and his team was published in April 2026 in the internationally renowned journal, 'Frontiers in Microbiology'. Dr. Ram Karan and his team conducted their research on 'Halorubrum lacusprofundi' - a microorganism found in the Deep Lake on the Antarctic continent. Deep Lake presents two sets of extreme conditions: firstly, it is an extremely cold environment, and secondly, it is highly saline. For a microorganism like 'Halorubrum', surviving under such conditions is nothing short of a marvel, as such extreme environments are not found anywhere else on Earth.

Planets like Mars possess climatic conditions strikingly similar to those found in Antarctica's Deep Lake—the very environment in which 'Halorubrum' thrives. Consequently, this research on the microorganism will prove instrumental in determining how life could potentially survive on Mars or on other planets with similar environmental characteristics.

Dr. Ram Karan and his team have identified key characteristics of proteins essential for survival in extreme environments—such as those found on Mars—through this research.

What did study on 'Halorubrum' reveal?

While studying 'Halorubrum' - a microorganism capable of surviving the extreme conditions of Antarctica—the team discovered small yet significant differences between the proteins of ordinary organisms and those of 'Haloarchaea'. It is precisely these differences that enable 'Haloarchaea' to withstand extreme conditions, such as high salinity, dehydration, and extreme heat or cold. 'Halorubrum' is a species of 'Haloarchaea'.

The most significant aspect of this study is that the researchers simultaneously analyzed the structures of over 3,000 proteins, finding that this adaptation did not occur in just one or two specific proteins, but rather in a coordinated manner across the entire protein system (the proteome). These differences in protein structure enable these organisms to survive in conditions of both extreme cold and high salinity—even when temperatures drop significantly below the freezing point of pure water.

This breakthrough in understanding *Halorubrum* proteins could also pave the way for the creation of various unique enzymes and catalysts for use in biotechnology. Such enzymes could prove invaluable in the future for manufacturing pharmaceuticals, bioremediating polluted areas, and producing fuel with lower energy consumption.

Is There Mars-like Conditions in Antarctica's Deep Lake?

Scientists believe that the environment conducive to the emergence of life on Mars is remarkably similar to the conditions found in Antarctica's Deep Lake. Deep Lake is more than six times saltier than the oceans. NASA scientists have gathered evidence suggesting that liquid water once flowed on the surface of Mars. Temperatures on Mars range from -143°C to +27°C—a temperature range remarkably similar to that found on the Antarctic continent.

It is not yet known whether or not microorganisms are present in the Martian atmosphere; however, NASA missions such as the Curiosity rover and the Mars Reconnaissance Orbiter are working to determine this. In this regard, the work of Dr. Ram Karan and his team has paved a new path for scientists. It is hoped that their discovery will prove beneficial to people across the globe.
