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’

Elon Musk has been slammed by the Israeli government after offering to send SpaceX’s Starlink to Gaza. The tech mogul said over the weekend that he would send Starlink to “internationally recognised aid organizations” in Gaza after a telephone and internet blackout in the city. He added that it was not clear who has authority for ground links in Gaza, but “no terminal has requested a connection in that area”. Responding to Musk’s post on X, Israel’s communication minister Shlomo Karhi hit out at the tech mogul, claiming that Hamas militants would use Stralink technology for “terrorist activities” and vowing that Israel will fight the move. “Israel will use all means at its disposal to fight this,” Mr Karhi wrote. “HAMAS will use it for terrorist activities. Perhaps Musk would be willing to condition it with the release of our abducted babies, sons, daughters, elderly people. All of them! By then, my office will cut any ties with starlink.” Mr Musk has insisted that SpaceX will take “extraordinary measures” to ensure the technology is only used for humanitarian reasons. It is unclear what those measures are. “Moreover, we will do a security check with both the US and Israeli governments before turning on even a single terminal,” he added on X. It comes after telecommunications were cut in Gaza over the weekend, leaving millions of residents without power or means of contact as Israel widened its air and ground assault. International humanitarian organisations said the blackout, which began late on Friday, was worsening an already desperate situation by impeding life-saving operations and preventing contact with their staff on the ground. Following the blackout, Palestinians appealed to Mr Musk to send Starlink satellites to Gaza. “Gaza is under bombardment, the internet and telecommunications have been cut off. They need Starlink immediately,” Anastasia Maria Loupis, a doctor, wrote on X. It comes after Mr Musk was widely praised for providing Ukraine with Starlink following Russia’s February 2022 invasion. Starlink satellites were reported to have been critical to maintaining internet connectivity in some areas despite attempted Russian jamming. But since then, Mr Musk has come under scrutiny after declining to extend coverage over Russian-occupied Crimea, refusing to allow his satellites to be used for Ukrainian attacks on Russian forces there. Mr Musk allegedly feared doing so would trigger a nuclear response from Moscow. Since Hamas launched an attack on Israel on 7 October in which 1,400 people died, Israel has launched retaliatory airstrikes on Gaza, leading to the deaths of more than 8,000 Palestinians.
