Little tremors and wiggles on Mars' surface hold big importance in planetary science.
, “were already a part of the mission goals of InSight from the beginning.” This marks the first unambiguous detection of surface waves on any planet other than Earth, and revealed that Mars’ crust may be a bit more uneven than previously thought.Doyeon Kim, Martin van Driel, Christian Böhmalso show peculiar lighter patches on the Red Planet’s surface around the new crater, which the team identified as frozen water dredged up from below the crust upon impact.
This groundbreaking combination of observations opens the door for a much more detailed understanding of Mars and other rocky planets, from the physics of meteor impacts to the structure of planetary interiors and beyond. Unfortunately, this may be InSight’s last hurrah— , and in around four to eight weeks it will no longer have enough power to operate. The team sees this as a high note to end on: Their observations could pave the way for fresh discoveries on Mars.“The new results on crustal structure far from the InSight landing site will improve our overall understanding of the formation and evolution of the Martian crust,” says
