‘Marsquakes' point to liquid water in red planet's crust, study finds
Liquid water may be locked in rock just a few kilometres beneath Martian ground – much closer to the surface of the red planet than previously thought. Using data from Nasa's now-retired InSight lander, a China-led international team of researchers analysed seismic waves from 'marsquakes' and meteorite impacts recorded between 2018 and 2022. They revealed a mysterious zone in the planet's crust they said was best explained by a layer of water-saturated rock. If confirmed, this underground layer – between 5.4km and 8km (3.3-5 miles) deep – could hold as much water as a global layer up to 780 metres (2,550 feet) thick, according to their paper published in National Science Review last month. Do you have questions about the biggest topics and trends from around the world? Get the answers with SCMP Knowledge, our new platform of curated content with explainers, FAQs, analyses and infographics brought to you by our award-winning team. The amount matched what scientists believe to be Mars' missing water, after taking into account the water that has escaped into space, become locked into rocks or remains as ice and vapour, said the researchers from the Chinese Academy of Sciences, the Australian National University and the University of Milano-Bicocca. 'Our results provide the first seismic evidence of liquid water at the base of the Martian upper crust, shaping our understanding of Mars' water cycle and the potential evolution of habitable environments on the planet,' they wrote in the paper. Nasa's InSight lander arrived on Mars in 2018 with a unique mission: not to roam the surface, but to listen to what was happening beneath it. For four years, it used a sensitive seismometer to detect subtle ground movements caused by crustal stress and meteorite impacts. Just as doctors use ultrasounds to scan inside the human body, scientists pieced together information about Mars' subsurface layers by studying how seismic waves travel through the Martian interior. Before shutting down in 2022, InSight recorded more than 1,000 seismic events, creating a trove of data that researchers are still analysing today. A breakthrough came in 2024, when a team from the University of California San Diego and UC Berkeley found that Mars' mid crust – around 11-20km deep – could contain fractured rock fully saturated with liquid water. Their study, based on theoretical models, made the first strong scientific case that Mars might still hold underground water. The new study, led by Sun Weijia from the Chinese Academy of Sciences' Institute of Geology and Geophysics, went a step further. While most previous Mars seismic studies relied on low-frequency data, which could only detect large-scale structures, Sun's team used higher-frequency signals, which gave them a much sharper view to about 500 metres in resolution, of the top 10km of Mars' crust. Looking at signals from three specific seismic events recorded by InSight – including the strongest quake ever recorded on another planet – the researchers identified a clear drop in wave speed at around 5.4km to 8km deep. This usually points to a layer of porous rock filled with liquid water. At that depth, conditions on Mars are warm and pressurised enough for water to stay liquid. The researchers say this zone could represent a kind of 'last refuge' for liquid water on modern Mars. While the discovery is scientifically significant, the water is still far too deep to be accessed with existing drilling technology. It cannot be used for future missions – at least not any time soon. The team also cautioned that their estimate was based only on data from the region directly beneath the InSight lander. Future missions with better seismometers could help confirm their findings, both at the InSight site and in other regions across Mars, they wrote.

Scientists find hint of hidden liquid water ocean deep below Mars' surface
When you buy through links on our articles, Future and its syndication partners may earn a commission. There might be a hidden ocean's worth of liquid water below the surface of Mars, seismic evidence suggests. According to a new paper published April 25 in the journal National Science Review, recordings of seismic waves from deep within the Red Planet indicate that a layer of liquid water may be lurking in the Martian rocks between 3.4 and 5 miles [5.4 to 8 kilometers] below the surface. The total volume of hidden water could flood the whole of Mars' surface with an ocean 1,700 to 2,560 feet [520 to 780 metres] deep, around the same volume of liquid that is contained within Antarctica's ice sheet, the study authors estimated. Related: NASA rover discovers out-of-place 'Skull' on Mars, and scientists are baffled Our neighboring planet was once abundant in water. In the time between Mars' formation 4.1 billion years ago to about 3 billion years ago, the Red Planet is thought to have been extremely wet, with features like valley networks, delta formations, and layered sedimentary rocks suggesting sustained water flow. However, this abundant liquid water "vanished as the planet transitioned to become the cold, dry environment we see today," paper co-author Hrvoje Tkalčić, a professor of geophysics at the Australian National University, said in a statement. Over time, Mars lost its magnetic field, and solar radiation began stripping away its atmosphere. With a thinner atmosphere, surface temperatures dropped; the planet's liquid water began to escape into space, become trapped as ice in the subsurface or polar caps, or become locked in hydrated minerals within the planet's crust, the researchers said. However, these methods of water loss have previously been shown to not entirely account for all the water that is estimated to have once flowed on the Red Planet, with a large volume of "missing" water going unaccounted for. This conundrum has long puzzled scientists, posing the question of whether there is still liquid water hidden on Mars that we have yet to find. This new research suggests that there is indeed liquid water buried deep below the surface of the planet. Upon analyzing seismic data from NASA's InSight lander, which landed on Mars in 2018, researchers found that seismic waves within the planet's interior — caused by asteroid impacts and marsquakes in 2021 and 2022 — appeared to slow down between 3.4 and 5 miles [5.4 to 8 kilometers] below the surface. They suggest that this could be due to the presence of liquid water hidden within porous rocks, as seismic waves travel more slowly through liquid than they do through more solid materials. "This 'low-velocity layer' is most likely highly porous rock filled with liquid water, like a saturated sponge," Tkalčić and another study co-author Weijia Sun, a professor of geophysics at the Chinese Academy of Sciences, explained in an essay for the Conversation about the new study. "Something like Earth's aquifers, where groundwater seeps into rock pores." The researchers suggest that this liquid water could make up the total volume of water missing from previous calculations. "Our study indicates it's possible that much of that ancient water percolated through the porous surface rocks and was retained underground," Tkalčić said. "This also matches estimates of the 'missing' water on Mars from other studies."

The potential presence of liquid water on Mars is exciting to scientists, as liquid water is essential to life as we know it. While these potential reservoirs deep below the planet's surface could host some form of Martian life, we won't know if the liquid water even exists until we can drill deep into Mars and find it for ourselves. "Future missions with seismometers and drills are needed to confirm the presence of the water at these depths and gather more clues," Tkalčić said.
