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.Reminder for those who don't know: on Mars, the sky is pink-reddish during day, and blueish at sunrise/sunset.

I still say mental health will be the top 3 risks. Behind oxygen starvation and radiation.
The sun of Mars is the same size as the sun of Earth.
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.The sun of Mars is the same size as the sun of Earth.
Damn those last 4 from Saturn onward. Hard to imagine. What a dark cold feeling.
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.At those distances, the sun is merely the brightest star in the sky...
All of the Kepler multi-planet systems (1705 planets in 685 systems as of 24 November 2015) on the same scale as the Solar System (the dashed lines). The size of the orbits are all to scale, but the size of the planets are not. For example, Jupiter is actually 11x larger than Earth, but that scale makes Earth-size planets almost invisible (or Jupiters annoyingly large). The orbits are all synchronized such that Kepler observed a planet transit every time it hits an angle of 0 degrees (the 3 o'clock position on a clock).
Planet colors are based on their approximate equilibrium temperatures, as shown in the legend.
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.At no time did I say apparent size.

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.

I think if we wanted to do everything but the propulsion part we'd be pretty close in terms of raw technology.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.
Anything worth going in tiny quantities from space will be rare earths...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.
