    yup. 6 chairs in there.

    I think the renewed interests in Mars exploration and sustainability are driving some technological growth in the area of vertical farming. I don't know so much about plants, but I know the insect food industry is growing, and it is similar in that insects are farmed indoors. Maybe I should work on some more complete urban farming systems too? I haven't seen any produce advertising as being grown indoors, but it seems like a logical next step after the insects.

    I watched the NASASpaceflight mirror to avoid this.

    It just feels weird because they use ignition as 0 instead of release. Shuttle and Saturn both started up around then in relation to liftoff.

    Great to see! Now make it sub $10k.

    Are they gonna go on time or are the people gonna have to sit in their rocket seats through hours of countdown holds like every previous test flight?

    A hollow planet would collapse into a sphere immediately under its own gravity. Visually? (SpaceEngine: ) Not too much. I've never seen a game give us the proper Einsteinian mechanics surrounding one, though. Having a supermassive black hole in KSP2 to fool around in would be interesting, either in a mod or in the base game. Perhaps one in a very old globular cluster would be calm enough to approach. I know they wouldn't add it without doing the physics right, though, so I'm not expecting it anytime soon. I wouldn't want a black hole without actual warped space, time dilation, etc.

    It's worth noting that Venus has an "ocean" of supercritical carbon dioxide in the lower atmosphere. This is not liquid CO2 but it is similar, having properties of both liquid and gas. As for a liquid CO2 ocean, I don't see any reason why it shouldn't exist. It just needs the right temperature and pressure, much like our water oceans and Titan's methane lakes. A liquid carbon ocean would sit underneath an utterly inhospitable planet, you could send a drop probe over it but it would be destroyed long before touching the ocean. Better to just orbit from afar. It also wouldn't be possible with no atmosphere, as OP suggests. However, there ARE some liquids that would exist in extremely tenuous atmospheres such as the likes of Io, Pluto, and Triton. Mercury (the metal, not the planet) would remain liquid under such low pressures. These would be very interesting to explore.

    Yes, every one has a serial number on it, this would be so the inspecting person could say "Tile xxxx-xxxxxx needs replacing" and they would know what type of tile it is and where to find it on the ship.

    I was hanging out underneath Endeavour yesterday and got a good look at the tiles. Yeah, there are a lot of similar-looking rectangular tiles, but it could be that they have slight curves or varying depths that we can't see. What was really scary was the quantity of scores and dents in the heat shield from launch debris. There is a ~6 ft long stretch of replaced tiles, insinuating a scar that long on a previous flight. That is what Starship will hopefully avoid, so the tiles won't take such an absurd beating on every launch. Shuttle tiles seem to have taken more damage during LAUNCH than in performing their actual function.

    I feel like an appropriate "improper" or informal classification would be that anything you can walk on by its gravity can be called a "planet" as a synonym to "world". The scientific designations still stand.

    Today I paid my respects to B1019 at SpaceX HQ!

    Look around, take in the view. Check my O2 valve flow. Scrape at the sand with my boot. Hop around.

    No. Pluto's heart is cold nitrogen ice and does not care what you think. Unless you would care to accept 13 planets?
  15. cubinator
    Pluto is a Dwarf Planet. It is also a Really Cool Thing. One thing it is NOT is "demoted". Another thing it is NOT is something that cares what type of object it is.

    Nonzero. "Scheduling conflicts" could mean almost anything. For example, a person could get hurt and need a couple months before they're space-ready. As unlikely as it is, there is some genuine reason why this person is being placed on a later flight. They'll no doubt still get access to Mr. Who, etc. but it will be on the ground instead of both ground and space.
  17. cubinator
    Maybe something came up more recently. Or they believed they could work out a new schedule.

    Sounds delectable!

    Stainless steel was too expensive to weld; rocket is now built out of LEGO bricks. Delightfully counterintuitive!

    Need to distract it with space shanties and zero-g ping pong.
  21. cubinator
    For the booster test? Or the Starlink launch?

    The forum gods updated something. I saw it on another forum too.

    If a Mars colony isn't self-sustaining, then forget about Mars as the final destination. Make the entire solar system one big self-sustaining colony. Then do it again with the Milky Way. Fly spaceships between Earth and Mars and Venus and Titan and Europa and Pluto as much as you need to. Fill a whole tanker with salt. Life finds a way.

    I'm no balloon expert, but I think certain chemical coatings could do the trick. They do make gloves and lab coats to resist acid, after all. Probably something shaped more or less like a typical balloon, with denser habitation areas and rooms hanging below, and a large, mostly-open common area above. Trees and plants could be planted there for closed-loop life. Perhaps the balloon could be made to contract or expand to control altitude, although that would require some tremendous strength that could tear it apart if something broke. Of course, venting air to lose altitude is a less than optimal solution. Fins and sails on the outside could control the motion of the city.

    Why is the wind speed such a problem? You can just ride it on your floating city and then the day/night cycle becomes 4 days long instead of 200+. Already the air is habitable enough in a balloon full of breathable air, as long as adequate acid protection is present.
