Sol 150 raws are up so this seems like a good time to start a new thread...
Hang on in there Phoenix... -------------------- |

They don't. As of yesterday they had still not commanded Phoenix out of Lazarus mode, in which it is only trying to communicate, not do anything else. We'll have to wait until they can get the terminal science mode sequence uplinked. Even then, we may not get pictures -- pictures require more power than pressure, temperature, and TECP measurements, so those will be done and telemetered first before Phoenix tries to take any pictures with any remaining power.

Any idea what the terminal science mode sequence consists of ?

I think we are all suprised at how quick the power situation went downhill.

It was always going to be hard to figure out precisely when Phoenix was going to start to die but we did know that the power loss situation was going to start getting dramatically worse around now. I had estimated that, all thing being equal, she would have been operating at around 50% of initial solar panel power per sol around now and dropping dramatically towards zero. The sudden storm has thrown a wobble into that and I am certain that my estimates of available power tended to overestimate the power from the panels at low solar angles but even so I'm somewhat surprised that she's gone into near death mode this early - I had thought we'd be closer to Sol 200 (and ~25% of initial power levels) before she started to die from loss of power. Clearly though my original estimates were quite a bit out of kilter with reality.
