  Nearly two years after NASA 's InSight Lander mission ended, scientists are still making groundbreaking discoveries from its data. The latest finding? A massive underground reservoir of liquid water on Mars ! This water lies deep beneath the surface, between 11.5 and 20 km , but it provides the best evidence that Mars still has liquid water in addition to its frozen poles . Representation of water (Credit:- AI) This astonishing discovery opens up new possibilities for the Red Planet's past climate and its potential to sustain life! While drilling to this depth would be a challenge for future human expeditions, the presence of water gives scientists new hope. Water is essential for life as we know it, and now we know Mars has plenty—hidden beneath its surface. Seismic data from InSight hints at a vast reservoir of groundwater that could theoretically host life, much like the deep mines and ocean floors on Earth do. Could Mars have the conditions to support life? While no l...

  NASA 's Curiosity rover mission is a story of innovation and daring that redefined Mars exploration. Twelve years ago, on August 5, 2012 , Curiosity made history by landing on Mars using the revolutionary " sky crane " maneuver—a technique that would change how we explore the Red Planet forever. This artist’s concept shows how NASA’s Curiosity Mars rover was lowered to the plan The sky crane maneuver was a game-changer born out of necessity. Curiosity was too large and heavy to land using the airbag technique that had been successful in previous missions. Instead, NASA engineers devised a bold new method: a robotic jetpack would lower the rover to the Martian surface using nylon ropes, then cut the ropes and fly off to crash-land safely out of range. This unprecedented approach allowed for a more precise landing and opened the door for future missions, including the February 2021 landing of NASA's Perseverance rover. Enhanced with terrain-relative navigation, this ...
