    DMSP F-17 and F-18 satellites have a story to tell, are we listening?

    Of all greenhouse gasses, water vapor is the most important... it is the Sun which drives our climate. Period.

    3% of all greehouse gasses is CO2, 97% is 'other' gasses, mostly water vapor. Now, of the CO2 in the atmosphere, 3% of that 3% is man-made... which is to say, 97% of CO2 in the atmosphere is natural. So to believe CO2 is the cause of 'global warming', if there really is global warming, 0.009% of CO2 being caused by man - so negligible as to be a fart in a wind storm.

    The amount of CO2 in the atmosphere in 1750 or so was 280 ppm. The amount of CO2 in the atmosphere in 2016 is around 400 ppm. That means about 120 ppm of the CO2 in the atmosphere got there between 1750 or so and now. Human society is the only thing we know of that has significantly changed on Earth since then, and is simultaneously able to create CO2, so the increase in CO2 concentration probably has something to do with us.

    You are correct in saying that the Sun is much more influential than humans in determining the climate of any planet orbiting it. However, I don't agree that it is a closed argument, that the Sun is the sole factor. Nothing in science is ever a closed argument. Everything affects everything else, including temperature-wise, and I see no reason why humans/their civilization can't have some impact on the temperature, whatever it may be. 

    This is all I'm willing to say on the matter. 

    Why mankind not returned to Moon

    Well, if you're talking about why they didn't do more Apollo missions, or expand the Apollo program, it's because they beat the Soviets to the Moon, and then there was no point in continuing and it cost a lot, so they stopped. As for why they haven't done any separate manned lunar missions, it's because everyone is hyping about Mars and life and Mars and water and Mars, and the Moon doesn't help that cause much. It can teach us how to live under low gravity, sure, but it's easier and less expensive to do that in Low Earth Orbit in a ring or something. Same goes for living sustainably. The only thing I can see us using the Moon for in the near future are mining operations for fusion plants (He-3) or tourism (historical sites, Earthview, etc.) I think that the Moon is going to have a largely tourism- and energy-based economy in the future, because it's close to Earth and material/population exchange between the two is relatively easy and much faster.

    What if those are debris from Dyson sphere?

    Short scenario... one civilization starting to build Dyson sphere, second civilization notices it and is starting war... first civilization loses war.

    Might as well be comets in that case. Debris either way. Plus, it's really hard to destroy a Dyson sphere, given that it must be made of a really strong material to withstand tidal forces in its orbit.

    @ProtoJeb21 Maybe those who can't join but want to can sift through the data from people that look, so that the people who can look can, well, look for exoplanets.

    Also, we should make a facebook group.

    I agree. Somebody did this with asteroids a while ago, I remember. I took part in that. I want this to happen so I can help. 

    Does science need to be proven?

    in Science & Spaceflight

    I say it is all math, and if you end up with multiple competing theories, choose the one that has the least discrepancies from the stuff that has been proven. You can prove it eventually if you want, but science is best guess. And the theory that has the least discrepancies or the most evidence is the best guess in this case. 

    What if we confirmed Aliens around KIC 8462852?

    I'm surprised to be the first post here. Wow.

    I think the more space-excited people would be really, really excited about it for a while, and the layman would be all like "Well, look at that!", and then everything goes back to normal as people realize it doesn't affect us in any major way, and we won't be able to communicate with these people for over a thousand years, and the aliens have no way of knowing humans are even a thing. Outside the space/scientific community, things would almost entirely go back to normal within weeks or months. We'd want to keep track of what they're doing, but there's no need to worry about them.

    They aren't going to harm us, we know this because they are thousands of years more technologically advanced than us (they had begun building a Dyson Sphere in the 500s AD) and they undoubtedly know about Earth and its situation by now. They don't know about us, i.e. modern civilization, but they have probably observed Earth in giant telescopes and seen by the atmospheric composition that it must have life. They would then react similarly to how we would to us discovering them.

    It is a monumental discovery that significantly affects either party for no more than a few weeks or months. If we discover them, we're seeing them as they were 1490 years ago. That doesn't help us or harm us. In 1490 years during which they probably knew there was life here, and seem to have made no efforts to colonize or whatnot, they probably want to leave us alone. And vice versa: if they discover us, they're seeing our planet as it was 1490 years ago. That doesn't help or harm them, either. If there's a planet that they know has life, and they also know that nothing from that planet has tried to 'invade' them, they probably think that we want to leave them alone.

    TL;DR: One civilization, discovering the other, is going to be quite excited about it for the first few weeks, then (aside from the scientific community) basically moves on with life because the discovery isn't that important in their day-to-day lives.

    An Ode to Tylo

    Nice!

    I also happen to have one:

    Around Jool there's a large moon called Tylo.

    It's well known as a dead spaceship's silo.

    The ships built from trash,

    on Tylo they'd crash,

    and the Kerbals would stay for a while. :)

    Real Space Program [Need Launch Controllers] [Launch 1/14/17]

    in KSP1 Mission Reports

    Posted · Edited by Findthepin1

    Regardless of whether I can take on another role, I do have to rescind my role as Recovery. It takes up a lot of my time and it is changing my schedule around. I had meant to do this on the 25th, right after the launch, to give everyone a lot of time to find a new one before the next launch, but I ended up taking time to think about it. I am going to hang around and ask/answer questions, though. I hope you can find another Recovery person before the May 8th launch. I am going to continue looking for a better role for me in the Real Space Program.

    Here's a good reference. Jupiter is a little smaller than the ISS, which is just barely too small to see it's shape. Sometimes when the ISS passes directly overhead you can almost tell it has a definite shape, but can't quite discern it. If you have really good vision, you might have a hint that Jupiter or Venus is a little more than a point, but you couldn't quite be able to make out it's shape, I don't think.

    I have seen Venus as a narrow crescent once, IIRC.
