Have you heard? NASA’s InSight lander is set to touchdown on Mars next Monday, November 26. So, grab your popcorn and leftover turkey and get ready to witness the latest Martian robot land on the Red Planet. InSight, aka Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (holy acronyms, NASA!), is on a quest to understand the insides of the planet. Scientists aren’t exactly sure what Mars looks like beneath the surface or how that material is layered. In layperson’s terms - is Mars more like a hard-boiled egg or a soft-boiled egg? Food metaphors aside, discovering how much of Mars's core is liquid is one question (among many) that can help us better understand how planets age, cool, and change, ultimately providing huge insight into our own Earth.
