ESA astronaut André Kuipers is running experiments on the International Space Station that are shedding light on conditions deep inside Earth. Orbiting some 400 km above us, Geoflow is offering insights into the inner workings of our planet.

Descending 3000 km under our feet, Earth’s mantle is a semi-solid fluid under our thin outer crust. The highly viscous layers vary with temperature, pressure and depth.

Understanding how the mantle flows is a major interest for geophysics because it could help to explain earthquakes or volcanic eruptions. Computers can model it, but how can scientists be sure they are correct?
