A new study into the Earth beneath our feet has discovered that an ancient ocean floor structure could be wrapped around the planet's core which could be taller that Mount Everest in some areas. A brand new high-resolution mapping of the core has uncovered things that scientists previously didn't know according to a study that was first published in April. The discovery found that a thin but dense layer sits at around 2,900 kilometers below the surface at the Core Mantle Boundary where rocks meet the molten outer core of the planet. Geologist Samantha Hansen from the University of Alabama is quoted in the study saying: "Seismic investigations, such as ours, provide the highest resolution imaging of the interior structure of our planet, and we are finding that this structure is vastly more complicated than once thought." She adds: "Our research provides important connections between shallow and deep Earth structure and the overall processes driving our planet.” Hansen and her team conducted the research from 15 different stations in Antarctica by using seismic waves created by Earthquakes to create a map of what the inside of the planet looks like. The team identified the unexpected energy within seconds of the boundary-reflected wave from the seismic data. The findings show that although the layer is very thin it does spread for many, many kilometers and has been called the ultra-low velocity zone (ULVZs) due to its strong wave speed reductions. Due to the properties of the ULVZs the experts believe that the layer could vary dramatically in height. Geophysicist Edward Garnero from Arizona State University adds: "The material's thickness varies from a few kilometers to [tens] of kilometers. This suggests we are seeing mountains on the core, in some places up to five times taller than Mt. Everest." These underground mountains could play a significant role in how heat escapes from the Earth's core and power magnetic fields and volcanic eruptions. The team's studies suggest that the layer could encase all of the core but further research will have to be carried out to determine if that is the case.

Four volunteers have entered a simulated Mars habitat as part of a year-long Nasa experiment to test astronauts’ resilience to isolation and other psychological stress factors. The CHAPEA (Crew Health and Performance Exploration Analog) mission will see the participants live and work in a 158-square-metre (1,700-square-foot) habitat at Nasa’s Johnson Space Center in Houston, Texas. It is the first of three one-year simulated Mars missions, which each aim to assess the health and performance of crew members when living in confinement with limited resources. Participants will take part in simulated spacewalks, science experiments and habitat maintenance, while also attempting to grow crops for food. “The simulation will allow us to collect cognitive and physical performance data to give us more insight into the potential impacts of long-duration missions to Mars on crew health and performance,” said Grace Douglas, CHAPEA principal investigator. “Ultimately, this information will help Nasa make informed decisions to design and plan for a successful human mission to Mars.” The four members of the CHAPEA mission are research scientist Kelly Haston, structural engineer Ross Brockwell, emergency medicine physician Nathan Jones and microbiologist Anca Selariu. Each were chosen after Nasa put out a call for “healthy, motivated” applicants in 2021. There have been several previous research projects involving simulated Mars habitats, with the Mars-500 missions between 2007 and 2011 seeing volunteers spend months locked inside a facility in Mosco, Russia. The HI-SEAS program in Hawaii also saw participants spend time living in isolation, though one mission lasted just four days after one of the crew members suffered an electric shock. Nasa plans to return humans to the Moon within the next three years as part of its Artemis missions, which the US space agency hopes to use as a foundation to eventually send astronauts to Mars. Private space firm SpaceX also plans to send people to Mars aboard its Starship rocket, which is currently under development at the company’s Starbase facility in Texas. SpaceX boss Elon Musk said a second attempt at an orbital flight test will be made before the end of August, after the first attempt in April ended in a large explosion just minutes after take off. The 480 million kilometre (300 million mile) journey to Mars is expected to take around seven months, with the planet’s orbit meaning that a travel window only opens up every 26 months. This means that any return mission would likely take close to four years to complete.
