5,000 days on Mars, and nuclear-powered Curiosity rover is still out there sending postcards.NASA just dropped a fresh view of the Red Planet, shot by the rover to mark its 5,000th Martian day on the job.Sit with that number for a second. A Martian day runs a little longer than ours, so this machine has been grinding across that rocky terrain for longer than most of us keep the same phone.Look at the frame. Layered rock slabs scattered everywhere, hills glowing on the horizon, the sun hanging low and pale.Nobody's standing there to see it.Curiosity is.
