Been busy with other things for a while, so it's nice to be back and see all the photo imaging work on the site going from strength to strength
![]() I think a lot of you guys would really enjoy "Curiosity On Mars:First Results" 3 part x approx 2 hr presentations at the EuroGeosciences Union General Assembly published on the EGU Channel on YouTube on May16th. Plenty of good listening for the weekend! Although I enjoy the NASA press briefings, it's great to hear key mission scientists talking full-on to their peers. The talks travel along at a nice fast thought provoking pace! http://www.youtube.com/watch?v=hPbbhfGg0nc Admin: Moved post from 'First Drill' thread. |

Given that methane decomposes rapidly when exposed to UV this finding to me implies that any methane in the atmosphere (if there ever is a significant amount of it) is very transient, and most likely related to occasional geological events.
We need a couple of seismometers on Mars BAD. -------------------- 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.

Given that methane decomposes rapidly when exposed to UV this finding to me implies that any methane in the atmosphere (if there ever is a significant amount of it) is very transient... Are you suggesting that there was methane when MEx looked, but there isn't any now? The lifetime of CH4 in the atmosphere is short, but not that short (hundreds of years.) Occam's Razor suggests something other than transience. ![]() -------------------- Disclaimer: This post is based on public information only. Any opinions are my own.
