I knew the sun would be smaller, but was amazed how much smaller. I'm wondering now if full daytime is about the same as a hour after sunup. Also didn't know about the color but assumed the blue part after picture. If we do send people to Mars it will take some adapting. Talk about feeling alone and away from home. They better load those capsules with some Xanax.
I still say mental health will be the top 3 risks. Behind oxygen starvation and radiation.

Man. I'm just going to say nope. Think about it a minute. Hell even our moon is larger/smaller due to distance and it is "close" orbit. Unless you are just being stupid about it. Of course it is the same size regardless , what we see is not however, which is what I am obviously saying.

Ya that chart shocked me. Mars shocked me. I knew it would appear smaller but not that small, let alone almost like another star that far out. Amazing considering those planets rotate on the same plane due to dust formation around the sun and maintained it that far away as they formed. One day I am going to look up how that happened from a disk of particles. How did a "core" strong enough to generate gravity form from a rotating disk of dust. That's right, right? When you think about it all, it is pretty awesome. To think our sun is just a spec to some other suns just boggles.

Most of the initial theories of system formation was that inner worlds were basically proto-cores for gas giants, except the solar wind blew most of it during formation, so you got small worlds until a "safe distance", where it switched to jupiter and all that.
Then, exoplanets happened, and you've got gas giants next to their star, and all kind of system fuckery. So, if you look at the system formation, pick any text written during the last five years. Anything before is going to fall into solarocentrism

We know. We also know you knew what I meant. No one on this damn planet thinks true object size varies over distance, but it is apparent size which becomes smaller. As witnessed by looking at your car from 10 feet away or 100.
In other words, stop being such a fucking cunt.

I can't wait till we start sending autonomous robots to use solar-powered lasers to break off chunks off this asteroid (or a similar one), use "something" to turn it into a heat shielded whiffle ball, and then use some kind of moon-mined hydrodgen fuel to send it into earth.

One would think by the time we have the tech to enable autonomous robots capable of doing that, we would be beyond needing raw materials from space in tiny quantities like that anyway.

Probably not. If what they're calling ai continues to progress even slowly you could have rudimentary adaptable machines in a generation. You have that in a VERY crude form with alexa right now. You toss one out, tell it to check in for orders every so often, and wait. Maybe the ai is what it's checking in with at mission control.
If spacex continues to advance their rockets, tossing one out might be a few tens or hundreds of million of total investment for a possible return of who knows... double sounds great. But some percentage breakpoint.
Summer movies go 150 to 300 million to make. It's not outside the realm of credible.
Maybe it could happen and even be practical within the century.
The wait would suck, and retrieval would suck. So maybe it's Easier to just not do that.
