    A ninth planet?

    in Science & Spaceflight

    Posted · Edited by Findthepin1

    I don't think it'll have any significant moons. If it really was ejected from the system earlier in time, any large moons would probably have been taken out one way or another. Being ripped away from the planet by a much larger one, or colliding with it, or colliding with another moon, or shattering within the Roche limit, or simply being thrown out into space. Lots of things can happen and I would be surprised if it has a large moon.

    Well, the balloon isnt under pressure, so it wont be a big blowout like Mark Watny's Airlock-cannon. it'll take time to lose lifting gas (unless the rip is at the very top of the balloon, but it still has to "burp" if the baloon is at all rigid) and since breathing air is also a lifting gas the habitat has a very low terminal velocity. (large cross section + low effective weight)

    I'd rather 1 or 2% of the good air get out than 100%.

    What if the broken section is the balloon?

    EDIT: Idea! We can make the balloon divided into "pods" like the things inside orange slices. Cut open an orange and you'll see them, they're like a centimetre long. There'd be lots of sort of balloon-pods inside the larger balloon. If one pops, it'd be insignificant.

    Yet Another New Planet Thread - see YAMO

    Cool! This means there's an 0.007% chance of there not being a planet-sized object out there. Isn't this still a dwarf planet? It obviously hasn't cleared its orbit. Also, I thought something like this might happen. See here. Also also, 10 Earth masses isn't a super-Earth. That's likely a small ice giant.

     

    Also also also: YANPT XD

    Surviving Seveneves: What would you do?

    I think I'd build a sort of vault like the one in Svalbard, but containing DNA and other important cells/whatever from just about everything that other things like this don't contain. It'd have a detector for atmosphere and when things cool down on the surface, if it's still breathable I'd clone everyone from the DNA and things to recolonize the planet.

    Either that or move as many people as possible to the rest of the solar system and hope that by the time Earth is fine the offworld colonies will have enough people to repopulate.

    BTW Earth might have a ring by then, yay :D

    Are you excited of PBR in KSP 1.1?

    I have some ideas about how they might look like, especially metal parts like engines etc.

    But Porkjet, you probably know what is going on

    Are you guys going to change water? Some other Unity 5 user games have nice waters, Ksp water is pretty dull and static, Im not sure but i dont think it's so hard to make decent looking water.

    Also underwater looks weird. We can see the horizon underwater and there's a big area on the seafloor surrounding your craft that is a different shade than the surrounding seafloor.

    Nuclear Winter and Global Warming?

    Whereas, if nuclear winter was a thing, you'd really expect Venus to be an icicle.

    90 atm of mostly CO2 is much more than enough to combat this. In Venus' case, the greenhouse effect is so much that the albedo practically doesn't matter and it'll still be hot at an even higher albedo. If Venus' atmospheric albedo was similar to Earth's or Mars', the surface would be like 7 or 800 degrees Celsius. gonna edit this l8r gotta go work

    It may be possible to engineer plants that can survived 48-72 hours of darkness.

    Speaking of which, how will we survive that? If you're free-floating in the habitable altitudes, your day will be something like four Earth days long. If you're tethered to the ground it'll last months. Can we adapt to a four-day cycle between sunrises? What's the theoretical limit for us humans to adapt to a day length?

    Quote: "Vulcans are the main source of water on venus, and some asteroids."

    Interesting. You mean like this?

    sorry :D

    Really though, IDK how much water is in a Vulcanoid asteroid. I assume you mean those. The orbits are close enough to burn off all the ice.

    I don't think these impact mining operations (the way we've been discussing it) are economically feasible. At best, by 2050 or whenever this will be tried, the costs for impacting something onto Venus, something large enough to fling pieces of the ground fifty kilometres into the air with enough precision for a blimp to catch them without popping or being damaged otherwise, are going to far outweigh the benefit gained from actually having those minerals. If it's something smaller knocked up into the air, like dust, it'll just block out the sun, which isn't good as I assume we'd be using solar power on such a base. It'd likely be the cheapest.

    Anything we got up to our base would also be very hot, like 1000 degrees hot. Even if we manage to impact something big/fast enough to throw rocks up to our base, the rocks would be very hot because of a) the heat at the surface and b) they were just thrown fifty kilometres through a very thick atmosphere by an explosion in already very hot conditions. We couldn't touch those rocks. Neither could any airship, or any native life in the clouds. It'd be akin to a supervolcanic eruption. Tons of rock at hundreds of degrees thrown into the upper atmosphere along with enough dust to create an impact/volcanic winter in the upper atmosphere.

    IMO only the dust would stay in the air long enough to cool down so we can pick it up. But at that point we'd likely be dead because the dust blocked out the sun and if we were using solar, we ran out of power.

    TL;DR It's economically unsustainable to knock minerals off the ground with impacts to capture them. Even if we could, it'd be a natural disaster similar to a supervolcanic eruption.

    What did you do in KSP1 today?

    I built a Mun Flyby mission. To recreate Apollo 13's course. But then the mission had an ironically Apollo-13-like mishap; there was no electricity. I ran out before the hohmann transfer burn. So I waited until I was over the KSC and got them down on my fifth try. The other times it was going too fast. The big three await plane pickup some ways east of the KSC.

     

    And IRL, I updated my terribly old 2010 iMac to OS X El Capitan from Lion.

    Umm, I get how you get off Venus, but how would you get BACK to a Venus Cloud Base?

    Propellers, perhaps? When you want the rover to go back, it can inflate a balloon around itself, making itself into a little airship that has a propeller to get it around horizontally. Like bags on the sides of the rover that can be filled up with hydrogen stored inside, maybe even hydrogen extracted from the sulphuric acid in the air.
