    Anti Satellite weapons

    I’ve tried this stock (kinetic kill vehicle) but doing so requires incredibly precise information on your target’s orbital characteristics and incredibly precise orbital maneuvers as well. Maybe if there was a command line interface where you could input a DV vector or something.

    Metallic Oxides--->Oxygen+Metal?

    Actually helium probably isn't the best inert conductor of heat, and that would raise problems like extracting the oxygen or whatever reactant produced. I guess the oxygen could be distilled out but that would require lowering the temperature very low and would be hard to do on a industrial scale.

    Air oxidizes hot metals. In vacuum, there'd be no need for covering the molten metal with dross all the time. That's the good part. The bad part is that lots of energy during electrolysis is spent on heating, and while that waste heat is easily vented on Earth by convection or air and conduction (actually, sometimes the problem is to save the heat, hence refractory material to insulate the reaction), in space it can conduct to the regolith poorly. The main path is radiative, but that's very inefficient, as we all know.

    Look at how many radiators ISS has, and it deals with a lot less heat.

    It would require serious chem-enginnering study to figure this out for a particular problem, but on the top of my mind, I'd say it would be very difficult to make such plant.

    Maybe the process could be done in a inert gas (like helium) so that the metal doesn't oxidize and the hot gas could be run through a heat exchanger immersed in a good coolant, like water. Better yet, the warm water could be used for powering the station.

    Stopping All Movement: Possible?

    in Science & Spaceflight

    Movement is relative to a certain point, with out that certain point movement is undefined and invalid. Say you had a certain theoretical point, and that we mapped every object in the universe, and things were at absolute zero (So molecules would stop vibrating and moving around), you could stop all movement. Of course, everyone would be dead as a result of the conditions, but it could be done. The amount of energy required would be massive, and storing all the energy (you have to store it because energy cannot be created or destroyed) would be hard without resulting in heat or movement. If everything stopped moving, I imagine everything would clump together in the middle of the universe (which would temporarily create movement and heat). Even doing all this, I'm pretty sure subatomic particles cannot be stopped (correct me if I'm wrong) All this would become irrelevant if a single particle was discovered that was moving. You can theoretically stop all movement in a system relative to a certain point, but it becomes exponentially difficult as you increase the size of the system, and stopping all movement in the universe would be near impossible.

    I was thinking about native sourcing of materials for colonies and such, and my mind went to the iron oxides present on mars. I figured that the rust could be decomposed into iron and 02, most likely using energy from solar panels. Does anybody know how much energy would be required for this reaction?

    Lifting Body Aircraft

    in KSP1 The Spacecraft Exchange

    I noticed that the mk.2 spaceplane fuselage parts produced some lift, and I was wondering if I could make a airplane fly without wings, just using the lift produced by the body. NASA made a few planes using this concept back in the 60s and 70s (ex. http://en.wikipedia.org/wiki/Martin_Marietta_X-24B) I put some parts together and came up with this:

    uWRyF#0

    It is not truly a pure lifting body aircraft, as the control surfaces act as little wings, but it is pretty close.

    Flying:

    It is a little unstable in the roll axis, and cannot really yaw that much, but it still flies. Max speed below 1000m is around 250 m/s. When taking off, it tends to bounce around some.

    There is not any real use for this aircraft (except for a compact reusable reentry vehicle, maybe).

    Has anyone seen a Meteor in .22 KSP, while using FAR?

    Hello, I have returned to the forums after a long absence. When I was playing .22 the other day, I was *trying* to fly a airplane in FAR, and I saw something that looked like a meteor or a spaceship reentering the atmosphere, of in the distance. I was flying straight out and I saw it far away, in line with the equator. I looked in map view to see if I left a craft on a suborbital trajectory (which I didn't) and when I returned, it was gone. Of course, I didn't think to take a screenshot first before I went into map view. My brother was there watching me, and he saw it too. Has anyone else see something like this?

    P.S.

    Am I the only one who thinks it looks like there is a stream at the end of the island runway, when you are high up?

    Well in theory, there is no need for armor on carriers, since they generally stay out of a battle. But it is often good to have armor on a carrier, since a airtight, er, uhm, spacetight defense is hard to acheive. One craft can always get through and screw the carrier over. An example would be in the American vs the British carriers in WWII. The American carriers had a wooden deck and would be devastated by Japanese Kamikaze attacks, whereas the British carriers often had 3 inches of steel armor on the deck, therefore were only minorly damaged by similar attacks. Whenever you don't have complete superiority, it is a good idea to have armor.
