NASA's Insight; Weather gives us regular weather updates from Insight's location on Mars, an example is shown below. Temperature is of the air around the lander.

Question: But does or has Insight or any spacecraft on the surface of Mars measure the surface temperature of the soil around it as well? Has any had a simple radiometer pointed downwards, either off to the side or directly below, in order to record surface temperature? Do either Curiosity or Perseverance have these?

  • $\begingroup$ @0xDBFB7 for this question I'm primarily interested in "downward pointing radiometers" or similar; non-contact, local surface thermometry from a surface craft. Insight's subsurface probe is designed to return temperatures from below the surface in order to measure heat flow I think, so it wouldn't really suffice. $\endgroup$
