Discovery of underground water system on Mars could point to the grim future awaiting Earth. Since the life forms known to humankind need water to survive, the area might be the best chance of having an alien encounter on the red planet. This is possibly the reason why the water bodies are able to stay liquid despite the extremely cold conditions of Mars’s south pole. The new study, now published in Nature Astronomy, is based on the data obtained from MARSIS – Mars Advanced Radar for Subsurface and Ionosphere Sounding, onboard the Mars Express spacecraft orbiting Mars. The findings were enabled by MARSIS, which is able to send radar pulses to penetrate the surface of a planet. Mars Express is a European Space Agency probe that has been orbiting the fourth planet from the sun since December 2003. The evidence suggests that vast lakes and rivers dominated the surface of Mars billions of years ago. How we test gear. "And as a result, we don't see with SHARAD that interface between the ice and the underlying surface. This subglacial lake, discovered by a ground-penetrating radar on the Mars Express spacecraft, is about 20 kilometers (12.4 miles) wide and perhaps no more than a meter deep. Since the life forms known to humankind need water to survive, the area might be the best chance of having an alien encounter on the red planet. A 13-member team of scientists has found multiple liquid bodies under the south pole of Mars. Start a conversation, not a fire. We've scanned the very first edition so you can enjoy it. "It’s like a dark cloud has gone away.". It entered orbit around Mars on 25 December 2003. The techniques used to analyse the radar data on Mars are similar to those used in investigations of subglacial lakes in Antarctica, Canada and Greenland. So if there is a lake there, SHARAD wouldn't see it.". Even after this breakthrough, the team spent years taking more observations of the south pole region. The data from MARSIS helped them confirm that it was liquid. The water thought to be responsible for Mars' intriguing seasonal dark streaks may be coming from very deep underground, a new study suggests. For the discovery of the water bodies on Mars, the scientists used the same techniques as used with Earth satellites to study the lakes beneath Antarctic glaciers. The largest underground lake measures about 20 x 30 km, and is surrounded by several smaller ponds. The water is thought to be very salty in order for it to remain liquid at cold temperatures. Read the first ever Electronics Weekly online: 7th September 1960. The Mars water discovery The findings were enabled by MARSIS, which is able to send radar pulses to penetrate the surface of a planet.

They may harbour unique ecosystems, providing useful analogies for astrobiologists exploring how life can survive in extreme environments. The findings, indicated in a new study, complement the 2018 discovery of a bigger saltwater lake in the area. “The main lake is surrounded by smaller bodies of liquid water, but because of the technical characteristics of the radar, and of its distance from the Martian surface, we cannot conclusively determine whether they are interconnected,” she further added in a statement. ESA’s MarsExpress spacecraft has discovered several ponds of liquid waterburied under the icein the south polar region of Mars. The finding also raises the possibility of an alien life dwelling in the subsystem at some point in time. In addition, the team could gather useful observations only at low altitudes and when the spacecraft was on the night side of Mars because the sun excites the ionosphere of the planet, which blocks radar signals. MARSIS, however, does not have the technological capability to look for channels or rivers connecting a system of lakes. In total, it took three and a half years to obtain 29 observations of the target location.

This is possibly the reason why the water bodies are able to stay liquid despite the extremely cold conditions of Mars’s south pole. Previously, in 2018, it revealed one underground reservoir in 2018, buried about 1.5 km below the ice. By Alun Williams ESA’s spacecraft Mars Express has discovered more water buried under the ice in the south polar region of Mars, the agency has announced. However, Nunes also cautions that scrutiny of the MARSIS team's findings is required before we can make any hard and fast conclusions. This method of averaging the information meant that sometimes the data contained a small, high reflectivity area, while other times it had mysteriously disappeared. Near the Mars southern polar ice cap, it found strong reflections of radar signals—differences between two layers known as echoes. Strong echoes imply a big difference in what's called dielectric permittivity. The spacecraft’s radar instrument, MARSIS (Mars Advanced Radar for Subsurface and Ionosphere Sounding), revealed one underground reservoir in 2018, buried about 1.5 km below the ice. All rights reserved, A 13-member team of scientists has found multiple liquid bodies under the south pole of Mars, The new study, now published in Nature Astronomy, is based on the data obtained from MARSIS - Mars Advanced Radar for Subsurface and Ionosphere Sounding, onboard the Mars Express spacecraft orbiting Mars, For the discovery of the water bodies on Mars, the scientists used the same techniques as used with Earth satellites to study the lakes beneath Antarctic glaciers, water body that the team had found on Mars. Scientists already had little doubt that there was, at one point, liquid water on Mars, thanks to tiny spherical deposits discovered by the Opportunity rover in 2004 and the comprehensive mineralogy studies conducted by the Curiosity rover. The finding also raises the possibility of an alien life dwelling in the subsystem at some point in time. It’s feared the discovery of a vast underground water system hidden beneath the barren surface of Mars could show that Earth is facing a bleak future. "CO2 ice is very transparent and is able to let the radar pulse penetrate into the ice much better than pure water ice," Orosei says, which is why it mimicked the signal one would expect from underground liquid water. Even if Picardi wasn't there to see, the MARSIS team realized his dream and revealed a frigid reservoir of liquid water beneath the southern polar ice cap of Mars. The Southwest Needs Water! The latest research builds on Nasa’s findings by showing that water systems are active across Mars. These bodies were found to be separated by dry areas, making up a patchwork of salty lakes. (Representative Image: NASA / Elderfox Documentaries). Led by Elena Pettinelli and Sebastian Emanuel Lauro of the Roma Tre University and Roberto Orosei of the National Institute of Astrophysics (INAF) the team of scientists was able to find multiple patches around the main water body. ESA’s Mars Express spacecraft has discovered several ponds of liquid water buried under the ice in the south polar region of Mars. Mars Express finds more underground water … revealed one underground reservoir in 2018. ‘It helps us to understand the similarities to our own planet and if we are going through the same climate evolution and the same path that Mars is going,’ he added. We propose an alternative hypothesis that they originate from a deep pressurized groundwater source which comes to the surface moving upward along ground cracks,’ Heggy added.
