Wow. That is some amazing engineering.
Have you read Andy Weir's book The Martian? It's a really interesting dive down into the minute details of how you might survive a disaster on Mars.

>>v Andy Weir's book The Martian?
Read it, and saw the movie too. The movie is a better-than-average rendition of the story IMHO.
I think I enjoyed the movie more because I had read the book first.
I recommend both.

Same. I also like how the book got started too, as a fictional blog post that grew into a book after much input from his followers.

I'm running all 3 of the above feeds. So far, LM's looks to be the best for visualization of where it is in the landing sequence.

I thought the same. The one you posted is mirrored on the nasa.gov/live site.

I caught a glimpse of the rover wheels. They looked to be hub-powered. Yep, they are.
Also found a great site on the rover itself

She's nuclear!
The power source is called a "Multi-Mission Radioisotope Thermoelectric Generator" or MMRTG for short. The MMRTG converts heat from the natural radioactive decay of plutonium into electricity. This power system charges the rover's two primary batteries. The heat from the MMRTG is also used to keep the rover's tools and systems at their correct operating temperatures.

Hub wheels just make sense. I think all the 21 century rovers have used them.
