The numbers of objects we have observed / plotted in the belt are likely dwarfed many fold by those not observed. So yes, there’s a lot to see in the Belt :)

It’s been bombarded by tiny super fast collisions.

When we consider that it’s about 5 miles (8 km) long and 2 miles (3.5 km) wide, then some of those craters took good hits. I assume any future interstellar craft would need some sort of force field or be armor plated to protect from it from such collisions.

Here’s a very quick and dirty 3D model from Doug Ellison posted on Sketchfab:

3rd times a charm?

It would seem bigger, but this is imaged with a wide angle lens. The lander has a lot more cameras, I’m sure we’ll get some better shots of Earth and a nice panorama of the lander’s surroundings in the coming days It’s mission will only last 60 days, so they have a lot to do in a short time.

I really admired and miss that guy.
