Always so strange and wonderful to see how these objects, entirely free of atmosphere or storm, can have such a “soft” look - with craters seemingly buried under a layer of snow or paste, or something. I wonder if that would be that be due to the phenomenon of regolith moving via “seismic shaking”, which is supposed to partially bury smaller features in these asteroid landscapes. Even these preliminary images have enough detail and apparent features to beguile the eye.

DJ definitely doesn’t appear as “soft” as Deimos or Atlas (out by Saturn), but those two moons are quite a bit larger than this inner main belt asteroid. A lovely reminder that there’s a lot to see in the Belt.

You’re not wrong about this thing being bombarded by tiny collisions, but we should note that the impacting bodies that made the craters visible in these images were a lot larger than dust or sand grains. It’s not surprising to see an object like this, within the asteroid belt, covered in simple bowl-shaped craters. From what the New Horizons probe to Pluto and the Kuiper Belt has seen, however, even dust grains are actually pretty sparse in the outer solar system. Even if there actually is a “second Kuiper Belt” as some of the NH team proposes, it isn’t that dusty. In interstellar space, I would expect dust grains to be even rarer, let alone sand or pebbles.

That being said, interstellar probes will definitely need some form of protection from hypervelocity impacts, however rare they may be. That’s one good reason we should be looking seriously at more modest (and more feasible) proposals for spacecraft that will reach large but attainable distances beyond the heliosphere (say, 75 billion kilometres out from the Sun). The best way to verify the dustiness of nearby interstellar space is to measure it directly. Scouts have their value.

It wasn’t even a trip into orbit. Their rather short voyage was a sub-orbital hop. A low orbit of Earth requires a speed on the order of 8 km per second - Blue Origin can make about Mach 3, from what I read, which is circa 1 km per second. You go up, you go down. That’s it. They don’t even go particularly high (~100 km), and the apogee doesn’t keep you “above the atmosphere” (LOL) for long. Given the risks, I’m not sure it’s worth it, personally.

If we really want to inspire people by pointing out women’s accomplishments in spaceflight and space exploration, maybe we should be talking about people like Eileen Collins (astronaut on key shuttle/station missions), Lindy Elkin-Stanton (science lead for Psyche, the first to a metallic asteroid), Maria Zuber (lead the GRAIL mission to the Moon, co-discovered the rifts in the Ocean of Storms), or Mimi Aung (lead engineer for the Ingenuity 'copter on Mars 2020). And I’ve only mentioned a few Americans with recent work here; the rest of the world has plenty of enterprising female space scientists and aerospace engineers.

I share the general distaste in this thread and on Lemmy generally for this sort of celebrity stunt, and I’m glad to see the criticism. I do sometimes think, however, that for a certain kind of person, Bezos and Musk are becoming associated or even synonymous with spaceflight/exploration generally, which is a dangerous association to make. People have many, diverse and very legitimate reasons for going to space - there’s a lot more going on than joyrides and ego trips.
