Mars insights from InSight

Geophysical and meteorological measurements by NASA’s InSight lander in its first year on Mars reveal a planet that is seismically active and provide information about Mars’s interior, surface and atmospheric workings. The InSight lander acquired this image of the mission’s seismometer on 26 January 2019.

    The first marsquakes detected by NASA’s InSight mission mark just the start of seismology on Mars. Both Earth and planetary scientists alike should embrace this new frontier of geophysics.

    The InSight mission on Mars is currently providing us with the first seismic data from a planetary body other than our own Earth since the 1970s. Past efforts will inform this next chapter in planetary seismology.

    The magnetic field measured by the InSight lander on Mars varies daily and is ten times stronger than expected. The field is inferred to originate from components of basement rocks magnetized by an ancient dynamo of Earth-like strength.

    Bubble-mediated flux of oxygen into the Labrador Sea surface ocean contributes to air–sea gas exchange, suggest observations from moored profiling and Argo float data. Climate models that omit the process may underestimate oxygen in the deep ocean.
