Australian National University scientists are scanning Mars to size up the planet’s large core and unlock its past, using ‘marsquake’ data from a NASA lander.
Scientists peer into Martian ‘engine room’
Scientists have figured out how to look inside planets in the solar system to learn more about how they evolved.
The Australian National University researchers have determined the Martian core is about 3620 kilometres in diameter, which is large but slightly smaller than Earth’s core.
Lead author Sheng Wang and co-author Hrvoje Tkalčić used data from a seismometer attached to NASA’s Mars lander and have published the findings in the scientific Nature Astronomy journal.
Using a single instrument to scan the interior of a planet had never been done before.
