Starting a new thread as we leave the landing site and start the drive around Seitah. It will probably be quite fast unless something interesting turns up in the ejecta of the craters along the path.
Here is a circular panorama for sol 379, already north of the landing site. Maybe there will be some drive-by shots of the landing site itself. Phil -------------------- ... because the Solar System ain't gonna map itself.

It's a nice sequence. I was surprized that the sun looks considerably larger in mast-z at 110mm than in the MSL eclipse sequences at 100mm, allowing for the 10% focal length difference. It turns out Mars is at around 1.42AU from the sun now, near perihelion at 1.38AU (so at best the sun would appear only a few percent larger). The closest MSL's been when recording video of a Phobos transit is around 1.48AU on sol 713, I believe. |

1) An interesting thing about the Phobos eclipse images is that Mars is nearly on the opposite side of the Sun from Earth, so the sunspots visible there give us an almost 360° view together with images taken from Earth at the same time.
2) Look at the wild shape of the shadow on Kodiak Hill. There is some interesting topography at right angles to the line of sight. |
