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

I question the accumulation assumption as well. Dust accumulation would be a different issue, but not a non-issue. Dust accumulates freely on vertical surfaces--see any pictures of posts on cal targets from MER. It sticks to camera windows, as Ralph said. Dust does not only 'fall' onto the surface--it is frequently far too windy for that. While there is a major advantage in dust being cleaned from vertical surfaces, that is different from avoiding accumulation. See this article.
In addition to the geometric loss (and seismic noise!) Ralph mentions, consider what happens in a dust storm, when you need every photon you can get: the arrays are aimed at the low Sun and have poor incidence angles when the Sun is high; but those low-Sun photons are the ones least able to get through the dust. |
