This is the first mission to land on Mars since 2012, when the Curiosity rover touched down.

More broadly, scientists seek to understand how Mars, and by extension all of the solid \u003ca href=\"https://theplanets.org/terrestrial-planets/\">terrestrial planets\u003c/a> (Earth, Venus, and Mercury included), originally formed over five and a half billion years ago—under the assumption that they all formed under similar conditions and processes.\u003c/p>\n\u003cp>InSIGHT’s \u003ca href=\"https://mars.nasa.gov/insight/spacecraft/instruments/seis/\">seismometer\u003c/a>, which will be placed on Mars’ surface with a robot arm — like a doctor’s stethoscope placed on a patient’s chest — will listen for seismic waves traveling through the planet’s interior. The tremors may be created by Marsquakes, meteorite impacts, or other weighty shifts of material. How those shock waves travel through Mars will let scientists piece together a sort of “sonogram” to probe structures and densities of Mars’ interior.\u003c/p>\n\u003cp>A \u003ca href=\"https://mars.nasa.gov/insight/spacecraft/instruments/hp3/\">ground-penetrating probe\u003c/a> will bore downward through several meters of soil, pulling behind it a string of temperature sensors that will measure how quickly, and how much, heat is escaping from Mars’ interior.
