For one Hubble, something like a dozen of Keyhole spy telescopes have been launched [0]. Just imagine the kind of science we would have gotten if we launched a dozen of Hubbles instead... [0] https://en.wikipedia.org/wiki/KH-11_Kennen

The science output of a given device usually shows heavily diminishing returns. I would say 12 Hubbles would have had at most twice the impact of 1 Hubble, probably less.

What are the odds in our lifetime there will be a probe sent into orbit and then down into the atmosphere with high-resolution cameras that can beam back imagery/video of the entire trip? I think it'd be fascinating to see what it's like both above and while descending through the clouds. Also, is it possible life could exist in the clouds similar to how we now speculate on Venus?

not from orbit, but from very very very high up.

I think one can readily argue (and I'm a physicist, so I really love outward-looking telescopes) that reconnaissance satellites will tend to make the world a more-peaceful place.

Uncertainty can lead humans to make decisions to handle a worst-case scenario that isn't actually taking place. High-quality imaging makes it difficult for nation-states to bluff or to understate the scale of decay/disaster and allows for finer-grained control of military escalation.

We are seeing the next evolution of these effects as ordinary citizens can now get access to imaging systems that were once the realm of the Keyholes. They are journalists and free press in the sky. The internment camps of Xinjiang can't be hidden: https://www.buzzfeednews.com/article/alison_killing/satellit...

We must, of course, be wary of the societal effects of these imaging systems. If only some have access to orbital imaging, the asymmetry in power can be substantial and the norms for privacy can erode.

Definitely agree. However, the long tail will likely include discovering some more 'improbably' results. For example, the researchers who ultimately discovered Phosphine on Venus this week had early requests for observation time on telescopes denied and seemed to have to have been extremely persistent to finally get their chance.

I'm really disappointed that JWST doesn't support visible light imaging. Maybe there's better science value to non-visible light sources but for PR it is great.

Not sure JSON Web Tokens can see any light really. The JWST on the other hand is meant to see further than what can be seen with visible light. We have bigger mirrors on the ground capturing visible light than what JWST could do.

Earlier quoted context omitted.

For a few hundred years now, we've been looking at the planets. Finally makes it sound like we just did this yesterday or within current life times.

For the past few hundred years until recently, we've been seeing bright and fuzzy dots. There's a difference between that, and ~640000 square pixels worth of details we see in the article.

Hubble is not new.

It never occurred to me that the Great Red Spot would be shrinking. It's logical that storm systems are dynamic (and finite) things, but I find it striking that in another hundred years, people may never think of Jupiter as having such a dramatic feature. And who knows what new ones may have developed. I suppose that's as much a commentary on how short a time we've been able to witness these phenomena as more than do…

As far as the history of it, early sightings may have been other storms.
