Twitter post by Thomas Schumann that has an image of two potential landing sites at

23-28 N x 108-112 E
24-30 N x 129-133 E

So it seems it could possibly land at
30 N x 134 E

That would put it at 18 degrees due south of the Viking 2 landing site at
48 N x 134 E
which I think is about 1100 km distant.

Assuming it could travel at 300 meters per day, I estimate it could reach Viking 2 in about 10 years of steady driving! If it didn't have something better to do, of course smile.gif

Even if it were possible to land or rove to the VL2 site, would you really want to? I'm no expert, but based on the area density of large rocks,
this is probably one of the worse sites that we've seen up close so far in terms of rover trafficability.

Using a helicopter would probably be a better idea (hint, hint).

Or just land there in the first place.

Viking 2 would never have gone to its site if the science team knew how rocky it was. They thought it was covered with sand. Now we know, it's absolutely off limits.


... because the Solar System ain't gonna map itself.
