James, that video is amazing, really impressive work. Somehow you managed to make the quality high enough and the motion smooth enough so that it really flows. Music choice works too!

I second that emotion!

Awesome Damia!
Here is the Rear Hazcam view video from Landing all the way to Sol-456. Not as many images as the front Hazard camera of coarse, but my best attempt anyway. http://www.youtube.com/watch?v=5N-oxoQAmm4 |

Ken reports some issue with wheel stall and electrical problem during Sol 455.

Ken reports some issue with wheel stall and electrical problem during Sol 455. I wonder if that has anything to do with the funny route, or if that was planned. Per the curiositymsl.com* and Midnight Planets maps, the rover turned around and looped back more than a few meters, and is facing SE instead of SW as usual at the end of the drive. Per the speed/elevation plot, it looks like there were some steep slopes and higher speeds (including one spike) at first, then the second part of the drive was slower, and you can see where it retraces the elevation curve. I try not to read too much into this preliminary telemetry data, but it's fun to try to figure out. * I know the underlying terrain is getting out of sync with the map, for reasons Joe has explained elsewhere, but I am looking at the shape of the path, not the features underneath it. |

That update on the electrical problem has me a little confused. Maybe an engineer will add some clarifying comments.
If a device has a 32 volt bus, shouldn't the deltaV between the bus and the chassis be 32 volts in the absence of any soft shorts? The update mentions soft shorts that dropped the deltaV from 16v to 11v to 4v, but was there an earlier event that dropped the voltage from 32v to 16v? Or, is there something else I am missing that causes the deltaV between a 32v bus and a chassis to be only 16 volts? Also, is it correct to suspect that with only a 4 volt margin remaining after 5 volt and 7 volt soft shorts, it is unlikely the electrical system can survive another, similar soft short? -------------------- ...Tom

The MSL bus is set up so the chassis ground is nominally halfway between the voltages of the battery and RTG terminals. -------------------- Disclaimer: This post is based on public information only.

At last! Sol 462 - some new images are on the ground.
