I thought the main advantage for MSL over MER in terms of drive distance per sol was the height of the mast cameras (as akuo mentioned) and also the resolution of MC100. Both mean potential obstacles can be spotted farther away, and so longer non-blind drives can be planned. (Also there's power, which can negatively affect MER drives in times of very low solar array output). Of course we'll just have to see what they can do with MSL. NAVCAMs have a higher vantage point and wider baseline and they yield good range data to 30-40 meters. MASTCAMs are yet to be used for driving. They have a narrow field of view so we would need more frames to cover an area similar to PANCAMs. Moreover, the foreshortening would still limit our visibility of potential obstacles. I doubt we will be able to extend MSL blind driving much beyond what MER did. The real advantage on MSL is the more powerful processor that should speed up VO and AutoNav driving.

Another advantage... no real worry about tau. Although dust storms will still be a concern for some of the instruments; keeping lens covers in place for instance. Both Winter and Tau will affect the heating requirements therefore reducing amount of science and drive/arm time.

Paolo Early on they did say MSL was little warmer than expected, which would mean slightly less power needed for heaters in the winter. The external actuators though would still need the normal amount of heating. |

Or perhaps when each thread is closed, an admin can change the title, with a prefix, such as "Sol 34 - Sol 58, Drive, Drive, Drive toward Glenelg". That's nice but redundant because it is already included on each topic's description. Check the second (and smaller) line below each thread's title here. |

The external actuators though would still need the normal amount of heating. Yes, Gale is a little warmer than we thought and we also have a bit more power than anticipated but that does not mean that for *driving* the Winter heating requirements are going to be more taxing. Currently we are not power limited but once the RTG starts to slow down, there will be differences between seasons. We'll see how much impact it will be.

I'm guessing the 200m per sol figure is hoped-for long drive capability based on experience with the MERs. From the below, it looks like the mission requirement was for 50m per sol. "The following table summarizes some of the key resources affecting operations and the required capability for each." [attachment=28100:Mission_...es_Table.jpg] http://msl-scicorner.jpl.nasa.gov/scienceplanning/ You know what? In this week issue of Aviation Week they wrote 40km (25 miles) a day! Ok that's a tipo...I wouldn't risk to put this remark in the "Bad reporting" topic! Well may be in "MSL Humor" one -------------------- |

Colour 2 frame mosaic close-up of part of the first of JB's gifs...
Such gorgeous detail and colour. Just wish I knew more geology... -------------------- |

Wow, this layer looks amazing! I can't tell the origin of it, but it lacks (as far as I can see) internal sorting. It could be a lot of things: tuff, debris flow depopsit, a breccia... we need to have a closer (and compositional) look at it
