An international team of researchers has found new evidence for the possible existence of liquid water beneath the south polar ice cap of Mars. The results, published in the journal Nature Astronomy, provide the first independent line of evidence, using data other than radar, that there is liquid water beneath Mars' south pole. The researchers, led by the University of Cambridge with involvement from the University of Sheffield, used spacecraft laser-altimeter measurements of the shape of the upper surface of the ice cap to identify subtle patterns in its height. They then showed that these patterns match computer model predictions for how a body of water beneath the ice cap would affect the surface. Their results are in agreement with earlier ice-penetrating radar measurements that were originally interpreted to show a potential area of liquid water beneath the ice. There has been debate over the liquid water interpretation from the radar data alone, with some studies suggesting
India's Mars Orbiter craft has run out of propellant and its battery drained beyond the safe limit, fuelling speculation that the country's maiden interplanetary mission 'Mangalyaan' may have finally completed its long innings. The Rs 450 crore Mars Orbiter Mission was launched onboard PSLV-C25 on November five, 2013, and the MOM spacecraft was successfully inserted into Martian orbit on September 24, 2014 in its first attempt. "Right now, there is no fuel left. The satellite battery has drained," sources in the Indian Space Research Organisation (ISRO) told PTI. "The link has been lost". There was, however, no official word from the country's national space agency, headquartered here. With fuel on board, ISRO had been performing orbital manoeuvres on MOM spacecraft to take it to a new orbit to avoid an impending eclipse in the past. "But recently there were back-to-back eclipses including one that lasted seven-and-half hours," officials said on condition of anonymity, noting that
