New Research Reveals Mars’ Red Colour Linked to Ancient Water Presence

New Research Reveals Mars’ Red Colour Linked to Ancient Water Presence

Mars has long been recognised for its striking red hue, a defining characteristic that has earned it the title of the ‘Red Planet.’ For years, the prevailing explanation pointed to iron oxide—commonly known as rust—forming in the planet’s dust. This process, scientists believed, took place over billions of years as iron minerals were ground down and distributed by Martian winds. New findings now indicate that Mars’ red colour may hold deeper implications, particularly in understanding the role of water in shaping the planet’s history. New Findings on Martian Dust According to a study published in Nature, researchers attempted to recreate Martian dust by using various types of iron oxides in laboratory settings. The team, led by Adomas Valantinas, a postdoctoral researcher at Brown University, analysed the dust using techniques employed by orbiting spacecraft. As per reports, their research revealed that the best match for Mars’ distinctive dust is a combination of basaltic volcanic rock and ferrihydrite, an iron oxide that forms in water-rich environments. Water’s Role in Mars’ Red Colour As per data collected from …

NASA’s InSight Mars Lander Captured with Dust Layers by Mars Reconnaissance Orbiter

NASA’s InSight Mars Lander Captured with Dust Layers by Mars Reconnaissance Orbiter

NASA’s retired InSight Mars lander was recently spotted by the Mars Reconnaissance Orbiter (MRO) in an image taken on October 23, 2024, using its High-Resolution Imaging Science Experiment (HiRISE) camera. The image shows dust build-up on the lander’s solar panels, which now match the reddish-brown colour of the Martian surface. Reports suggest this observation continues to provide insights into the movement of dust and wind patterns on Mars. InSight’s Mission and Retirement The InSight lander, which touched down in November 2018, was central to detecting Marsquakes and studying the planet’s crust, mantle, and core. NASA officially ended the mission in December 2022 after the lander stopped communicating due to excessive dust accumulation on its solar panels. Engineers from NASA’s Jet Propulsion Laboratory (JPL) in California continued to monitor the lander for any signs of reactivation, hoping Martian winds might clear its panels. However, as per reports, no signals have been received, and listening operations will conclude by the end of this year. Tracking Dust Movement The new HiRISE images were captured to monitor how dust …
