@SteichenFamily Their big problem is two things. One is McDonnelDouglas bought Boeing with Boeing's money. The other is the management becoming obsessed with the bottom line over everything else. They are an engineering company that builds aviation and aerospace systems. You cannot run a company like that as if it is a money laundering storefront.

Apophis on hearing that Aricebo had collapsed laughs maniacally. That aside, it would seem to me the the time frames during which Earths orbit has a greater amount of eccentricity the odds of a near Earth asteroid impact should be marginally higher. But then again maybe not.

I really did not expect perfect results but this actually went better than I expected. NASA would still working on the preliminary artwork.

Rotary arm launchers are theoretically possible for small payloads. There is also a short story about a moon base needing a much better computer system in order to track small projectiles that were placed into lunar orbit during a firefight between US and Soviet security forces.

I finally recently started watching season one. Things l find implausible. 1) The sheer size of the vessels. And in comparison the volume ofcargo they carry. A perfectexampld is the first shp we see. Canterbury. Why haul around all that extra mass to store ice when you could melt the ice. Distill and store all the contaminates and haul the water in bladders or just refreeze it and push the frozen block of ice. 2) The sheer internal volume of the ships themselves. I know its a TV show but in the future when there are actually miners etc working out in the belt l doubt they will have the internal volume to spare. The MCRN battle ship is even worse. 3) Not just the volume of living space but how it is laid out. Again its a TV show and had to be shot on realistic budgets in sound stages. Given a continuous drive how ever it works. Let go with the approximate 1/3rd gee of Mars. Even during coasting phases some artificial gravity is nice. IMO the mag boots aren't going to cut it. Yes l can see there usefulness. A better solution especial for a merchantman water hauler would be a spin section with multiple modules that rotate on bearings with hatches inbetween the sections. The modules are arranged in a ring or partial rings. When the ship is coasting or at rest the modules are in their rest position. Meaning you head is pointed toward the Axis of the ship. When the vessel is accelerating the modules rotate so that your head is pointing in the direction of acceleration. At low thrust the spin section can still rotate with the floor being canted. Go to the Atomic Rockets website and look up Ezekiel Wheels. I had this idea years ago only to find out that somebody beat me to it. The vessels control station can be on the ships axis in zero gee when at rest. 3) The inplied scarcity of water and other vital supplies. Given what we know about the Solar System today or evenwhen Corey was writing The Expanse the Asteriod Belt is rich in water. At least in terms of what a human society would need. Given that Carbonacous Chondrite asteriods can be up to around 30% water and Ceres should be rich in water. You get the idea. And when the actorsare traversing the tunnels water is just dripping on them. Tunnels. Another dumb idea. Why do so many SF shows use tunnels. 4) Spining Ceres up for artificial gravity. The amount of energy needed to dpin up a body the size of Ceres to provide 1/3rd of a gee would better spent building an O Niel habitat. The Docks on Ceres or Eros Station. Wouldn't these be better situated at the axis in zero gee. The huilding of Navoo/Nathan Hale or Tycho Station implies implies they they could build O'Niels. 5) Martian terra forming and importing "supplies". Why not divert cometary bodies that are already headed in system. And start small. Roof over part or parts of Valles Marinaris and establish habitats there. Plus Mars may have substantial subsurface water. And given any need of metals why not mine Mercury. 5) Stealthed spaceships. Given the implied number of ships running around the Solar System there has to be some sort of traffic control system. Lord knows you do not want to be cruising through somebodies exhusst plume of fusion reaction products. Plus once your drive is running everybody with decent sensors will see you. Lets not talk about waste heat. Maybe use it to power a laser pointed out of the Plane of the Ecliptic? Kenetic Weapons Systems. Those rail guns aren't just hitting their targets. The rounds that miss are now dangerous projectiles racing through the Solar System. How fast are they? Above Solar escape velocity? We know the ships are given travel times.

Hitting an asteriod with an anti tank round is really no different than the asteriod getting smacked by a stray chunk of rock. Doing it from a stand-off distance with a small anti tank cannon or missle would work equally well. But then we'd have people yelling about weapons in space

I suppose Elon still has the tooling for the carbon fiber tanks. I'm no rocket engineer but one idea for the ring joints on the BFR*. Use a narrow ring with a slightly larger diameter that just slips over the outside of the main ring. This narrow ring is slipped over the main structural section. You then electron beam weld the joint ring in place. Slide the next section in and weld that in place. Then weld the two main sections together. Yes you are adding weight but I suspect Space X was trying to go as light as possible. *I don't care what Elon calls it. It's still a Big Freaking Rocket

Eventually we're going to got on of these over a populated area at a low enough altitude to cause massive casualties. It might be a year. Ten years, 100 or RIGHT NOW😱😱😱

Has anything for New Glenn even been built?

Oh, software. That's so you can be connected to the NASA CGI image server and amaze your friends with fake space pictures. At least that's what a flattard would say. Face it the average person buying one of these is meerly hoping to get a glimpse of the blond across the way stepping out of the shower. 😉

Let's say we have an interplanetary passenger ship with the habitat volume being a torus. And the ship is capable of transporting say 200 people. What happens if all 200 passengers congregate in one small portion if the torus?

@manw3bttcks No easy solutions. But some day, soon hopefully, some nation, some corporation, some visionary will take a chance and build the first rotating habitat in LEO and start to gather data. And the initial research station is not going to be massive enough to damp out variations in mass distributions. Start with low gee environment. Say Lunar equivalent.

At some point in time we will be in the cross hairs. A largish body, say 500 meters across approaches unobserved from sunward. Say a body lurking in the Taurid Meteor Stream. And it impacts either near or in a densely populated region. I think this is what it is going to take for governments to really commit to finding and preventing such occurances

The problem is the centrifuge is still experiencing Earths 1 Gee acceleration. You can build a centrifuge to experience more than one gee. But not less.

If you are building a suit meant for use in weightlessness why do you even need leg mobility. Why couldn't the legs and lower torso simply go into a sleeve that attaches at the chest level to accommodate different body types.
