In November 2018, NASA’s robotic explorer InSight landed on Mars’ rocky, dusty, red surface. It was sent on a mission to answer questions about the Red Planet’s crust, mantle and core, known as the “inner space.” The robot is souped up with cutting-edge technology to measure the conditions on the surface and take a look at what’s happening beneath the crust, according to NASA.
In a recent finding, researchers announced that Mars’ crust looks like it has three layers. This is the first time that scientists have taken an inside look at another planet besides Earth, and the discovery sheds light on how these rocky planets may have formed billions of years ago, reports Alexandra Witze for Nature.
