NASA’s Mars InSight lander may have come to the end of its mission last year, but data from the lander is still being used to contribute to science. Data that the lander collected on marsquakes, seismic events that are similar to earthquakes, has been used to get the best look yet at Mars’s core.
To learn about the martian core, scientists used data from two marsquakes detected by InSight. One of these quakes was caused by a meteoroid impact, which helped scientists locate the exact source of the waves and model the waves’ movement through the planet’s interior more easily. The marsquakes were also on the larger end of detected quakes, so they had stronger effects.
One challenge for InSight was that the quakes originated on the other side of the planet from the lander, which is why they are referred to as “far-side.” That makes them harder to detect, but it also means that studying them can give more useful information as the waves travel through more of the planet.
