Thread created for posting MSL route maps and map updates.
Comments / suggestions adding value to the route maps are allowed, but discussions regarding the route itself and "future" paths are not. Use the currently active thread for the latter. Eduardo Tesheiner Moderator ----- Here's an updated map of activities near the landing site and the start of a map of the route to Glenelg. I may get one more step added to this before I have to take a break Aug. 31 to Sept 16, and I will resume it after that. Details will be revised as necessary as we go. Phil -------------------- ... because the Solar System ain't gonna map itself.

FWIW, I've been using the orthoimages from this DTM page:
http://hirise.lpl.arizona.edu/dtm/dtm.php?ID=PSP_010573_1755 Specifically: PSP_010573_1755_RED_A_01_ORTHO PSP_010639_1755_RED_A_01_ORTHO They are map-projected, but are also adjusted using the DTM data to be a view looking directly down. Mark P.S. Jack, that view is looking NE... |

Could rover shadows be used to get a rough fix? For example this shot:
http://mars.jpl.nasa.gov/msl/multimedia/ra...0427M_&s=42 NASA does mark the UTC time of the shots (one of the few bits of shooting conditions given), in this case 2012-09-18 09:38:11 UTC. An ephemeris program shows that the sun at the MSL site at that time was at 25.1° elevation and 275.1° azimuth, so the shadow of a vertical gnomon would be at 95°. Here's the image with the camera boresight and the approximate location of the right navcam shadow marked with red dots: The separation between the dots is 392 pixels horizontally and 188 vertically. The navcams are specced at 0.0468° per pixel, so that's 18° in azimuth and 9° in elevation. So an estimate of the direction of the camera boresight is 95° - 18° = 77° azimuth and -25° + 9° = -16° elevation--assuming the mast is vertical, using plane geometry, level ground, etc. As a rough check, there are about 384 pixels (16.4°) from the boresight to the horizon, which works out to pretty close to 0°. -------------------- |

My boss and sundial fanatic Bill Nye would love this Stellar fixes of one kind or another always seem to be the ultimate aid to navigation!-------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.
