    NASA's InSight lander installed a seismograph on Mars, and the marsquakes it detected have helped us map the planet's interior. This data provides the big picture of Mars' internals-how big the core is, whether anything is molten, and so on. But it doesn't capture the small details, like what the ground immediately below InSight looks like.
    This week, researchers described how they've managed to find quiet periods on Mars that lets them image closer to the surface. The results, combined with some nearby surface features, reveal...
