NASA’s InSight lander has detected two strong, clear quakes originating in a location of Mars called Cerberus Fossae – the same place where two strong quakes were seen earlier in the mission. The new quakes have magnitudes of 3.3 and 3.1; the previous quakes were magnitude 3.6 and 3.5. InSight has recorded over 500 quakes to date, but because of their clear signals, these are four of the best quake records for probing the interior of the planet.
This is pretty cool to note. A seismically-active Mars makes for a slightly more viable colony location. Quakes mean the core is still molten to a degree, which acts as a dynamo to create the magnetic field that surrounds the planet. While there’s little we can do to increase the strength of a planet’s magnetic field1, being able to measure and determine the composition of Mars’ crust will go a long way to giving us the confidence we need in sending people there long term 🙂
No, nukes won’t do it.
