We just got our best-ever look at the inside of Mars

NASA’s InSight robotic lander has just given us our first look deep inside a planet other than Earth.  More than two years after its launch, seismic data that InSight collected has given researchers hints into how Mars was formed, how it has evolved over 4.6 billion years, and how it differs from Earth. A set of three new studies, published in Science this week, suggests that Mars has a […]
