MSL Route Map Options

First post-holiday map update - a close-up of Yellowknife Bay. The main map will be updated tomorrow.

I may have Costello and Flaherty reversed here. If anyone has any extra placenames I would be happy to know about them.

Route map update.

An updated map of Yellowknife Bay.

Updating the route map with a few new feature names. Crest was observed on sol 125, but it is near the sol 124 position. It was 'shot' in the morning before the drive to the 125 end-of-sol location. My locations are always end-of-sol.

Looks like we will need an even more zoomed in map for the next few weeks.

I had to extend the close-up map to fit in the new drives.

EDIT - I posted too soon! right away another update so I have replaced the earlier map in this post with a new one. The actual route on sol 164 is conjectural at this stage and may be refined later.

Another small move towards John Klein. I modified the last move thanks to the very useful visualizations by mhoward and jmknapp. Current position and route still tentative.

PS - to get the distance given on jmknapp's log, this must also have been a back-and-forth drive.

This is an updated post of the full route map so far. The route has now been adjusted to match the latest HiRISE image of the tracks.

Here's the track showing the relative rover position for the last three drives, per NAIF:



Looks like it's doing a little stutter-step (moonwalk?) every so often as it goes.

Those are the VisOdom updates. The vehicle reports the position before and after VO corrects the rover position. It is not actual rover motion.

Thanks for clarifying that.

For scale, here's Phil's map with an image representing the rover superimposed:



And for fun, here's a first cut at an animation of the actual driving, sol 147-166--the registration might be a bit off, but this is how it comes out of the NAIF data:

Go home, rover, you're drunk

Joe, that animation is great. Every time I dare to think "wouldn't it be cool if..." a few days later you come out with exactly that!

Joe, that is pretty cool and very similar to the animations we generate. There are two suggestions I have to make it more realistic:

1) when turning you could put the wheels at the turn in place configuration (about 1 radian toed in), turns are done at about 1.25 deg/sec.

2) you could try to skip to the VisOdom updated position directly.

This is a really good way of displaying the rover motions relative to the size of the vehicle.
