Not all of the water on Mars escaped into space billions of years ago as previously thought, but instead substantial amounts may still exist deep within the planet’s mid-crust.
This water is believed to be trapped within tiny cracks and pores in rocks 11.5km to 20km below the Martian surface, a study has revealed.
While the depth of this reservoir makes it difficult for future human colonies to access, the discovery offers significant clues about whether Mars once hosted life or if it still might today.
The findings, published in the Proceedings of the National Academy of Sciences journal on Monday, are based on seismic data from Nasa's Insight lander, which allowed researchers to estimate this groundwater could potentially cover the entire planet if spread out across its surface.
Historically, research has shown that water once flowed on Mars in the form of rivers billions of years ago but much of it was thought to have either escaped into space when the planet lost its atmosphere, or became trapped as ice beneath the surface, particularly in the polar regions.
Dr Gordon Osinski, a planetary geologist and professor at Western University in Ontario, Canada, who was not involved in the study, said the research was important in advancing our understanding of the geology of Mars.
“While many planetary scientists have suspected that the subsurface of Mars – just like Earth – would contain lots of groundwater, this is one of the best studies so far to support this idea,” he said.
"Some of Mars’ water still undoubtedly escaped into space but between the evidence for water ice in the polar caps and ground ice in the middle latitudes of Mars, this evidence for water at depth in the crust does suggest less water escaped."
Although this underground reservoir may not be immediately useful for future colonists due to its extreme depth, the study still provides valuable insights into Mars' geological history and the potential for life on the planet.
“The reservoir won’t be of much use to anyone trying to tap into it to supply a future Mars colony,” said UC Berkley in California, whose academics led the research.
"Even on Earth, drilling that deep would be a challenge."
Dr Dimitra Atri, a planetary scientist at New York University Abu Dhabi, expressed optimism over the implications of the study, suggesting that life on Mars could be a reality.
“I believe that not only did life exist in subsurface Mars a few billion years ago, there is a possibility that it still exists today in some form," he said.
"We need to send missions to these regions to look for subsurface samples. ESA’s [European Space Agency] ExoMars mission is such an effort, which is scheduled to launch in 2028."
The European project will aim to search for signs of past or present life on Mars by drilling beneath the planet's surface to collect and analyse soil samples.
It will focus on regions where liquid water might have been or is still present, offering the best chances of finding evidence of life.
It was delayed from its original launch date of 2020 due to Covid-19 and was pushed back again because of Russia's invasion of Ukraine – Russia had been the main partner in the mission.
After the ESA's fallout with Russia, it managed to save the mission through an agreement with Nasa, which states the agency will help find a launch vehicle for the rover for lift-off in 2028.

Mercer, the investment consulting arm of US services company Marsh & McLennan, expects its wealth division to at least double its assets under management (AUM) in the Middle East as wealth in the region continues to grow despite economic headwinds, a company official said.
Mercer Wealth, which globally has $160 billion in AUM, plans to boost its AUM in the region to $2-$3bn in the next 2-3 years from the present $1bn, said Yasir AbuShaban, a Dubai-based principal with Mercer Wealth.
“Within the next two to three years, we are looking at reaching $2 to $3 billion as a conservative estimate and we do see an opportunity to do so,” said Mr AbuShaban.
Mercer does not directly make investments, but allocates clients’ money they have discretion to, to professional asset managers. They also provide advice to clients.
“We have buying power. We can negotiate on their (client’s) behalf with asset managers to provide them lower fees than they otherwise would have to get on their own,” he added.
Mercer Wealth’s clients include sovereign wealth funds, family offices, and insurance companies among others.
From its office in Dubai, Mercer also looks after Africa, India and Turkey, where they also see opportunity for growth.
Wealth creation in Middle East and Africa (MEA) grew 8.5 per cent to $8.1 trillion last year from $7.5tn in 2015, higher than last year’s global average of 6 per cent and the second-highest growth in a region after Asia-Pacific which grew 9.9 per cent, according to consultancy Boston Consulting Group (BCG). In the region, where wealth grew just 1.9 per cent in 2015 compared with 2014, a pickup in oil prices has helped in wealth generation.
BCG is forecasting MEA wealth will rise to $12tn by 2021, growing at an annual average of 8 per cent.
Drivers of wealth generation in the region will be split evenly between new wealth creation and growth of performance of existing assets, according to BCG.
Another general trend in the region is clients’ looking for a comprehensive approach to investing, according to Mr AbuShaban.
“Institutional investors or some of the families are seeing a slowdown in the available capital they have to invest and in that sense they are looking at optimizing the way they manage their portfolios and making sure they are not investing haphazardly and different parts of their investment are working together,” said Mr AbuShaban.
Some clients also have a higher appetite for risk, given the low interest-rate environment that does not provide enough yield for some institutional investors. These clients are keen to invest in illiquid assets, such as private equity and infrastructure.
“What we have seen is a desire for higher returns in what has been a low-return environment specifically in various fixed income or bonds,” he said.
“In this environment, we have seen a de facto increase in the risk that clients are taking in things like illiquid investments, private equity investments, infrastructure and private debt, those kind of investments were higher illiquidity results in incrementally higher returns.”
The Abu Dhabi Investment Authority, one of the largest sovereign wealth funds, said in its 2016 report that has gradually increased its exposure in direct private equity and private credit transactions, mainly in Asian markets and especially in China and India. The authority’s private equity department focused on structured equities owing to “their defensive characteristics.”

Sheikh Zayed's poem
When it is unveiled at Abu Dhabi Art, the Standing Tall exhibition will appear as an interplay of poetry and art. The 100 scarves are 100 fragments surrounding five, figurative, female sculptures, and both sculptures and scarves are hand-embroidered by a group of refugee women artisans, who used the Palestinian cross-stitch embroidery art of tatreez. Fragments of Sheikh Zayed’s poem Your Love is Ruling My Heart, written in Arabic as a love poem to his nation, are embroidered onto both the sculptures and the scarves. Here is the English translation.
Your love is ruling over my heart
Your love is ruling over my heart, even a mountain can’t bear all of it
Woe for my heart of such a love, if it befell it and made it its home
You came on me like a gleaming sun, you are the cure for my soul of its sickness
Be lenient on me, oh tender one, and have mercy on who because of you is in ruins
You are like the Ajeed Al-reem [leader of the gazelle herd] for my country, the source of all of its knowledge
You waddle even when you stand still, with feet white like the blooming of the dates of the palm
Oh, who wishes to deprive me of sleep, the night has ended and I still have not seen you
You are the cure for my sickness and my support, you dried my throat up let me go and damp it
Help me, oh children of mine, for in his love my life will pass me by.

What you as a drone operator need to know
A permit and licence is required to fly a drone legally in Dubai.
Sanad Academy is the United Arab Emirate’s first RPA (Remotely Piloted Aircraft) training and certification specialists endorsed by the Dubai Civil Aviation authority.
It is responsible to train, test and certify drone operators and drones in UAE with DCAA Endorsement.
“We are teaching people how to fly in accordance with the laws of the UAE,” said Ahmad Al Hamadi, a trainer at Sanad.
“We can show how the aircraft work and how they are operated. They are relatively easy to use, but they need responsible pilots.
“Pilots have to be mature. They are given a map of where they can and can’t fly in the UAE and we make these points clear in the lectures we give.
“You cannot fly a drone without registration under any circumstances.”
Larger drones are harder to fly, and have a different response to location control. There are no brakes in the air, so the larger drones have more power.
The Sanad Academy has a designated area to fly off the Al Ain Road near Skydive Dubai to show pilots how to fly responsibly.
“As UAS technology becomes mainstream, it is important to build wider awareness on how to integrate it into commerce and our personal lives,” said Major General Abdulla Khalifa Al Marri, Commander-in-Chief, Dubai Police.
“Operators must undergo proper training and certification to ensure safety and compliance.
“Dubai’s airspace will undoubtedly experience increased traffic as UAS innovations become commonplace, the Forum allows commercial users to learn of best practice applications to implement UAS safely and legally, while benefitting a whole range of industries.”
