Diverse types of organic molecules have been found on Mars by a Nasa rover. The material was detected by the Perseverance rover in the Jezero Crater on Mars, scientists said. Researchers are unable to rule out that the materials have a “biotic” origin, or are the result of life on the planet. But they might also be formed in other ways, such as interactions between water and dust or having been dropped onto the planet by dust or meteors. The findings suggest that Mars may have had a far more active past than we realised – and could have significant implications for the search for alien life. According to the study, understanding more about Martian organic matter could shed light on the availability of carbon sources, with implications for the search for potential signs of life. The Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals (Sherloc) instrument on the rover is the first tool to enable fine-scale mapping and analysis of organic molecules and minerals on Mars. Perseverance landed within the Jezero crater, the site of an ancient lake basin with high potential for past habitability, in February 2021. Since then scientists have been exploring the geological make-up of the crater floor using a suite of tools on board the rover that can take pictures of and analyse the rocks. Sunanda Sharma, Ryan Roppel and their colleagues analysed observations from two formations on the Jezero crater floor. Signals of organic molecules were detected on all 10 targets that Sherloc observed in the Jezero crater floor, concentrated in the Maaz formation, more than in the Seitah formation. The data showed diverse mineral association and spatial distribution that may be unique to each formation. The researchers suggest the diversity among these observations may provide insight into different ways that organic matter may have originated: potentially through deposition by water, or in combination with volcanic materials. Writing in the Nature journal, the authors said: “Our findings suggest there may be a diversity of aromatic molecules prevalent on the Martian surface, and these materials persist despite exposure to surface conditions. “These potential organic molecules are largely found within minerals linked to aqueous processes, indicating that these processes may have had a key role in organic synthesis, transport or preservation.” The findings are published in a new article, ‘Diverse organic-mineral associations in Jezero crater, Mars’, in Nature today.

Scientists have been forced to change their understanding of the inside of Mars after a major new breakthrough. Research looking at seismic waves that were generated when Mars was hit by a meteorite impact suggests that it has a previously unknown layer in its deep interior. Those waves were picked up by Nasa’s InSight lander, which was sent to Mars to better understand its seismic activity. The waves that the lander picked up can be used to get a picture of the anatomy of the planet, by watching how they travel around. The new data indicates the presence of a hitherto unknown layer of molten rock surrounding a liquid metallic core - the planet’s innermost component - that is smaller and denser than previously estimated, researchers said on Wednesday. Waves generated by quakes - including those caused by meteorite impacts - vary in speed and shape when journeying through different material inside a planet. Data from InSight’s seismometer instrument has enabled the planet’s internal structure to come into focus. The meteorite impact that occurred in a Martian highland region called Tempe Terra on Sept. 18, 2021, triggered a magnitude 4.2 quake and left a crater about 425 feet (130 meters) wide. It occurred on the opposite side of Mars from InSight’s location in a plains region called Elysium Planitia. “The importance of the far side impact was to produce seismic waves that traversed the deep interior of the planet, including the core. Previously, we had not observed any seismic waves that had transited the core. We had only seen reflections from the top of the core,” said planetary scientist Amir Khan of ETH Zurich in Switzerland, lead author of one of two scientific papers on the new findings published in the journal Nature. The behavior of the waves indicated that previous assessments of the Martian interior were missing something - the presence of a molten silicate layer about 90 miles (150 km) thick surrounding the core. This molten region sits at the bottom of the interior portion of the planet called the mantle. The researchers also recalculated the size of the core, finding that it has a diameter of about 2,080 miles (3,350 km), with a volume about 30% smaller than previously thought. The researchers said the mantle - a rocky layer sandwiched between the planet’s outermost crust and core - extends about 1,055 miles (1,700 km) below the surface. Unlike Mars, Earth has no molten layer around its core. One of the two studies published on Wednesday indicates this layer is fully molten, with the other indicating that most of it is fully molten, with the top portion partially molten. “The molten and partially molten layer is essentially composed of silicates (rock-forming minerals) that are enriched in iron and in radioactive heat-producing elements compared to the overlying solid mantle,” said Henri Samuel, a planetary scientist with the French national research organization CNRS working at Institut de Physique du Globe de Paris and lead author of the second study. The Martian core is made up mostly of iron and nickel, but also has some lighter elements such as sulfur, oxygen, carbon and hydrogen. The researchers concluded that these lighter elements make up about 9-15% of the core‘s composition by weight, lower than previously estimated. “This amount of light elements is not unlike that of the Earth’s core, which is estimated to be around 10%,” Khan said. Mars, the fourth planet from the sun, has a diameter of about 4,220 miles (6,791 km), compared to Earth’s diameter of about 7,926 miles (12,755 km). Earth is almost seven times larger in total volume. NASA retired InSight in 2022 after four years of operations. “We have learned a lot about Mars by studying the unique seismic record provided by the InSight mission,” Samuel said. “Planets are rich and complex systems because they are a place where many different types of processes coexist and act on various spatial and temporal scales, and Mars is no exception.” Additional reporting by Reuters Read More ‘Crystals brought back by Apollo astronauts indicate true age of the Moon’ Researchers reveal source of largest ever Mars quake Scientists investigate after huge shaking seen across Mars Scientists see huge explosion in space – and it could explain life Massive space explosion observed creating elements needed for life Tim Peake: Possibility of all-UK space mission a ‘very exciting development’
