That article says pretty much the same as the one from the Planetary Society, however this tweet from systems engineer that came a few days later is less optimistic now sad.gif

My take is that the likelyhood of Oppy waking up increases as time goes by until end of January 2019 then it drops quite rapidly. The idea being that between Ls 290 and Ls 310 we have seen cleaning events. As it stands Oppy likely needs more than one cleaning event to regain consciousness. Once the windy season is over Winter will get the vehicle too cold to survive. This is *my* take, not an official position of my employer, yadda yadda yadda.

I have a question for you Paolo. I am trying to get an idea of what the final physical state of what the rover was left in. The last hazcam's show that the arm was placed on a target with the APXS in contact and I vaguely recall reading in a planetary society update that it was a team's decision to leave the arm placed on that target during storm prep. I have not been able to locate that again. Was this the case? What was the final position that the camera mast in? I assume it was placed so the cameras were pointed down in such a dust storm situation. I just find it fascinating to know because the final known pose position for any surface mission would be how they would look for millions or even billions of years. It is how they will look like when astronaut's walk up to them. smile.gif

Yes, the APXS is down on the target. We didn't have any power to do anything except take the last tau measurement. The PMA is always "stowed" before a shutdown, that is the elevation is at least 17 deg below the horizon. We do not point the PMA straight down in case the elevation actuator stops working you can at least see a bit of terrain in front of the rover while having the cameras pointed down-ish.
