![]() Link to gif. Fortunately, this time USGS Scientist Ken Herkenhoff provides the explanation, better than I ever could, in Sol 289 Update On Curiosity From USGS Scientist Ken Herkenhoff: Heating Up: QUOTE Yesterday I was Geology/Mineralogy Science Theme Lead for the first time in months, so I was a bit rusty. We tried to fit some MAHLI imaging into the plan, along with overnight CheMin analysis of the Cumberland drill sample, but didn't have enough power. However, we were able to plan a high-priority ChemCam observation of the drill tailings during the day (when warm) and early the next morning (when cold), to look for changes in hydrogen due to daily absorption/desorption of water vapor. The early morning ChemCam observation required pointing the instrument at the target the previous evening, to avoid having to heat and move the remote sensing mast at night. Thanks Paul, for pointing to Ken Herkenhoff's update via PM! ![]() |

Probably be some time before we see the formal results for the presence of hydrogen. So time for a little speculation here ![]() The early morning image of the laser strike area is much larger and appears to have a different profile than any of the earlier laser strikes on drill tailings. It actually looks more like an impact crater. So I speculate that the test may show that some moisture (maybe a heavy overnight frost?) was present on or within the surface which resulted in the generation of large quantity of gas by the laser induced plasma which vigorously ejected the surface materials resulting in the formation of this mini crater. Only 1 theory, let's see if anyone has a better one ![]() |
