The Answer

PacSci-Doku: Revealing Mars' Innards - The AnswerThe question in this edition is:

What has allowed scientists to “see” deep inside Mars?

The answer: Marsquake

The Martian lander, InSight, landed on Mars last year and recorded the first marsquakes. These were small compared to our earthquakes, but should still reveal much about Mars’ innards. The observed marsquakes appear to come from a fault some 1,000 miles from the landing site, probably caused by stretching of the Martian crust over the past millions of years. Read more about how marsquakes reveal what is happening deep underground.
