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.

The Tianwen-1 rover will be named .... Perseverance?

Fear not, people of Earth. Yutu 2 didn't get the name that was most popular in its shortlist and this one probably won't either. Personally I like the name which translates as 'Red Hare', though in the old tale 'Red Hare' was actually a horse.

So, they're actually going to be doing "Operation Barbarossa"...

Since 弘毅 is pronounced "Hongyi" and not "Perseverance", I think the rover would probably be named Hongyi. It means literally "great will", and oddly enough is best known for being the name of a venture-capital firm. I wonder if advertising shenanigans are involved.

Congratulations to CNSA! Exciting times indeed ahead for this mission! smile.gif

Now that it's arrived please move the discussion to the new Tianwen-1 At Mars thread.

A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.
