"If I can keep talking to my mission team, I will—but I’ll be signing off here soon," NASA said in a tweet from the lander's perspective.
"Before these events, surface waves had not been unambiguously identified on any terrestrial planet other than Earth."
The natural sculptures were discovered just a week after a rock fracture resembling an alien doorway.
After dust covered the rover's solar panels, only a Martian dust devil can save the mission now.
A magnitude 5 "marsquake" was recorded last week on Mars, by far the strongest tremor ever detected off of Earth.
For the first time, scientists have mapped the internal structure of a planet other than Earth, revealing the properties of Mars' core and mantle.
The InSight probe also recorded 174 "marsquakes," revealing that the red planet is clearly geologically active.
Earthquake-like seismic activity on Mars has been, until now, theoretical.
On its first sol on the red planet, the mission sent home images of a dusty landscape, a lander selfie, and a wide shot of Mars from space.
And there's a picture!
InSight is the first Mars mission to focus on the red planet’s interior, and will drill a hole five meters into its surface.
