Congratulations to the InSight team on a successful landing! We'll discuss the remainder of the mission here.

Very nicely done, Station!
Re static charge, it's of course too early to tell if this is happening or not. Never seemed to be a problem for cams on other landed spacecraft, though they also didn't land dead square in dustbowls. If that is what's going on here then I'd expect it the charge to gradually dissipate over time since the lander is in contact with the surface and all of InSight's components are electrically bonded with each other to form a reference ground plane, like any other aerospace vehicle. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

Re static charge, it's of course too early to tell if this is happening or not. Never seemed to be a problem for cams on other landed spacecraft, though they also didn't land dead square in dustbowls. Another interesting bit of context is the recent end of the massive dust storm. Maybe dust accumulates charge during such events and tends to lose it over subsequent months and years. There is research supporting the occurrence of lightning in martian dust storms. There was, I think, at least one martian year in every other cases between a major dust storm and the other seven successful landings (2001 until the MERs landed being just over a martian year). In fact, the possibility of an electrical discharge killing the Soviet Mars 3 lander has previously been raised, and the Mars 2 lander failed for yet-unknown reasons. Those entries happened before the 1971 dust storm had ended. Those clumps of dust may just be a clue as to what happened to the Soviet missions in 1971. |
