Is there life on Mars? Water reservoirs found under planet's crust could hold key

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.

Direct flights from the UAE to the Nepalese capital, Kathmandu, are available with Air Arabia, (www.airarabia.com) Fly Dubai (www.flydubai.com) or Etihad (www.etihad.com) from Dh1,200 return including taxes. The trek described here started from Jomson, but there are many other start and end point variations depending on how you tailor your trek. To get to Jomson from Kathmandu you must first fly to the lake-side resort town of Pokhara with either Buddha Air (www.buddhaair.com) or Yeti Airlines (www.yetiairlines.com). Both charge around US$240 (Dh880) return. From Pokhara there are early morning flights to Jomson with Yeti Airlines or Simrik Airlines (www.simrikairlines.com) for around US$220 (Dh800) return. 

The trek

Restricted area permits (US$500 per person) are required for trekking in the Upper Mustang area. The challenging Meso Kanto pass between Tilcho Lake and Jomson should not be attempted by those without a lot of mountain experience and a good support team. An excellent trekking company with good knowledge of Upper Mustang, the Annaurpuna Circuit and Tilcho Lake area and who can help organise a version of the trek described here is the Nepal-UK run Snow Cat Travel (www.snowcattravel.com). Prices vary widely depending on accommodation types and the level of assistance required.

One in nine do not have enough to eat

Created in 1961, the World Food Programme is pledged to fight hunger worldwide as well as providing emergency food assistance in a crisis.

One of the organisation’s goals is the Zero Hunger Pledge, adopted by the international community in 2015 as one of the 17 Sustainable Goals for Sustainable Development, to end world hunger by 2030.

The WFP, a branch of the United Nations, is funded by voluntary donations from governments, businesses and private donations.

Almost two thirds of its operations currently take place in conflict zones, where it is calculated that people are more than three times likely to suffer from malnutrition than in peaceful countries.

It is currently estimated that one in nine people globally do not have enough to eat.

On any one day, the WFP estimates that it has 5,000 lorries, 20 ships and 70 aircraft on the move.

Outside emergencies, the WFP provides school meals to up to 25 million children in 63 countries, while working with communities to improve nutrition. Where possible, it buys supplies from developing countries to cut down transport cost and boost local economies.

 

Normcore explained

Something of a fashion anomaly, normcore is essentially a celebration of the unremarkable. The term was first popularised by an article in New York magazine in 2014 and has been dubbed “ugly”, “bland’ and "anti-style" by fashion writers. It’s hallmarks are comfort, a lack of pretentiousness and neutrality – it is a trend for those who would rather not stand out from the crowd. For the most part, the style is unisex, favouring loose silhouettes, thrift-shop threads, baseball caps and boyish trainers. It is important to note that normcore is not synonymous with cheapness or low quality; there are high-fashion brands, including Parisian label Vetements, that specialise in this style. Embraced by fashion-forward street-style stars around the globe, it’s uptake in the UAE has been relatively slow.

Multitasking pays off for money goals

Tackling money goals one at a time cost financial literacy expert Barbara O'Neill at least $1 million.

That's how much Ms O'Neill, a distinguished professor at Rutgers University in the US, figures she lost by starting saving for retirement only after she had created an emergency fund, bought a car with cash and purchased a home.

"I tell students that eventually, 30 years later, I hit the million-dollar mark, but I could've had $2 million," Ms O'Neill says.

Too often, financial experts say, people want to attack their money goals one at a time: "As soon as I pay off my credit card debt, then I'll start saving for a home," or, "As soon as I pay off my student loan debt, then I'll start saving for retirement"."

People do not realise how costly the words "as soon as" can be. Paying off debt is a worthy goal, but it should not come at the expense of other goals, particularly saving for retirement. The sooner money is contributed, the longer it can benefit from compounded returns. Compounded returns are when your investment gains earn their own gains, which can dramatically increase your balances over time.

"By putting off saving for the future, you are really inhibiting yourself from benefiting from that wonderful magic," says Kimberly Zimmerman Rand , an accredited financial counsellor and principal at Dragonfly Financial Solutions in Boston. "If you can start saving today ... you are going to have a lot more five years from now than if you decide to pay off debt for three years and start saving in year four."

Tips on buying property during a pandemic

Islay Robinson, group chief executive of mortgage broker Enness Global, offers his advice on buying property in today's market.

While many have been quick to call a market collapse, this simply isn’t what we’re seeing on the ground. Many pockets of the global property market, including London and the UAE, continue to be compelling locations to invest in real estate.

While an air of uncertainty remains, the outlook is far better than anyone could have predicted. However, it is still important to consider the wider threat posed by Covid-19 when buying bricks and mortar. 

Anything with outside space, gardens and private entrances is a must and these property features will see your investment keep its value should the pandemic drag on. In contrast, flats and particularly high-rise developments are falling in popularity and investors should avoid them at all costs.

Attractive investment property can be hard to find amid strong demand and heightened buyer activity. When you do find one, be prepared to move hard and fast to secure it. If you have your finances in order, this shouldn’t be an issue.

Lenders continue to lend and rates remain at an all-time low, so utilise this. There is no point in tying up cash when you can keep this liquidity to maximise other opportunities. 

Keep your head and, as always when investing, take the long-term view. External factors such as coronavirus or Brexit will present challenges in the short-term, but the long-term outlook remains strong. 

Finally, keep an eye on your currency. Whenever currency fluctuations favour foreign buyers, you can bet that demand will increase, as they act to secure what is essentially a discounted property.
