Propellant depot based Mars architecture.
kerbiloid replied to Exoscientist's topic in Science & Spaceflight
Why zero boiloff? Boiling point -200..250° C, equlibrium temperature for Venus..Mars orbits -100..+50°C. Would boil off and how! -
Yes, can. And now calculate delta-Energy to deliver the ice from an asteroid (icy ones are of course far from Sun, not next to Earth) - or compare an energy to deliver, say, 1 t of methane from Titane with heat energy which this 1 t of methane gives when being burnt. And you get a sad result: it's energetically simpler to deliver the fuel from Earth and to make methane from CO2 and H2O on Earth than to deliver it from Titan.

Most of those double/triple stars of course belong to galactic arms or bulge, I presume. Just because most of stars do. While the Sun stands between arms, far from bulge, So, those "most stars" rub one against another much more often than Sun does. Of course, they interact much more intensively. While the Sun is so lonely, so forgotten... Far from the madding crowd.

If you have a ~1000 t orbital shipyard, you can build there a ~1000 t space cruiser. If you have a ~1000 t cruiser on orbit, you must supply it with ~10000 t of fuel (maybe per flight, maybe per year, maybe per several years - doesn't matter). To put on orbit ~10000 t of fuel you must launch ~200 000 t of rockets which means 100 SaturnV per ship just to deliver the fuel. Simple nukes do not solve the problem as their ISP is just 2..3 times more than chemicals have. So, you need an Earth-orbit tanker with ISP ~10000...100000 s to stay in healthy boundaries. And if you have ISP 100000, why do you need all that orbital stuff at all? You just sit into your "Thunderbird 2"-style ship on the backyard and fly to Pluto. So, no orbital shipyards, would never appear at all.

Stanford Torus mod looks like what you describe. http://forum.kerbalspaceprogram.com/threads/84106-0-90-Stanford-Torus-0-6 As you can see, it consists of just several complicated parts, so part count is very low, which allows FPS to be more or less appropriate. A funny problem with it. As any craft gets loaded only when it is inside the physical range from you (usually, ~2 km), this huge torus appears at lightning speed right before your face when you approach to it. Another sample of super-structure is Katlantis Hotel from an old movie. Also with low part count as I can see. Wayland has several beautiful samples. http://forum.kerbalspaceprogram.com/threads/24677-%280-23%29-Wayland-Corp-Development-and-released-download-Thread-%28new-parts%29 So, maybe if you use Ubiozur Welding Continued mod to pack many parts together, the Kraken will be indulgent to you. http://forum.kerbalspaceprogram.com/threads/107273-0-90-UbioZur-Welding-Ltd-Continued-2-1-1-%282015-01-14%29?p=2113214&viewfull=1#post2113214 Of course, TweakScale can be useful to increase your creation.

Yes, sorry. A wrong term. -
Yes, KSP Interstellar Antimatter tank does that.

How to stop bases exploding?
kerbiloid replied to funkcanna's topic in KSP1 Gameplay Questions and Tutorials
The more parts has your base, the more differently directed forces effect it. At some moment, at some place, the local tension between some parts exceeds their hardness, and you get a rain of parts flying around. Even "elastic" KAS struts are not the remedy. Due to such problem, Roverdude created "proxy logistics" mechanism in his "USI Kolonization System". Station buildings are not connected, but resources are being "teleported" from one module to another one. -
NASA developing a new, eco-friendly propellant
kerbiloid replied to Frida Space's topic in Science & Spaceflight
From ecological pov, "NH3...NO3" means "synthesized from ammonia" which means "synthesized from natural gas and polluting the atmosphere with NOx and COx when being produced" which means "to pollute the air not at the space centerm but at the chemical plant" which means "to sweep the rubbish under the carpet". -
From my pov, Mk 1-2 hatch would be over pilots' heads - as in any historical command pod with forward-looking viewports (Mercury, Gemini, Apollo). Also, side vieports would be much smaller, also as historical craft have. There's nothing to look at - so, why to weaken the hull? For example: as in FASA Apollo CM (it's almost perfect) or Super67 pods (except of its hatch placed aside). Also, pencil+finger retouch texture better would be replaced either with "white bacground + black lines" as spaceplane parts, or with "solid aluminium" as FASA and Tantares parts. Gemini-style 2-seat command pod looks very useful, btw. Not as a Gemini-style spaceship (it's trivial), but as an ejectable crew cabin for, say, orbital tug or interceptor. Being attached to an orbital station, carrying crew of a pilot and an operator, it usually returns to the station to refuel. But in emergency case can just eject the cabin and land. But a historical Gemini had a narrow nose filled with equipment. So, that would be not a historical Gemini replica, but a Gemini-style pod with wide nose with a pass-through to the space station.

So, Dres is an ideal place to store radioactive wastes and for life imprisonment. Nobody cares, relatively easy to reach and land, no atmosphere, no ocean.

If the mining doesn't depend on vessel.status = "splashed".

Btw, the reentry module itself is the same - 2m form factor, 2 seats (not scaled up). Orbital module (below the reentry one) has 3 m diamater  the same as MOL or the small diameter of TKS. Two seats in the reentry were placed not side-by-side (as in common Soyuz), but 69 - as in old Dark Star movie. Between there was an additional hatch in the reentry's floor and heatshield  also as in MOL and TKS.

Where would you land on earth?
kerbiloid replied to Mad Rocket Scientist's topic in Science & Spaceflight
To protect the probe from rust, heat and frost - at a place with mild and relatively dry climate. So, no deserts, oceans, tundra, mountains, jungles. To investigate seasonal changes - somewhere not far from sea, but not on the shore. Not in a bog, but somehere on hills. To get diverse geological samples at the same place - in some region with complicated geological structure and without thick layer of soil. That means some ancient hilly meadows between 35°N and 50°N with multiple traces of geothermal activity. I.e. on some European spa. -
It's a multidimensional asynchronous cyclical fractal.

Voyagers are 100 AU far from Sun ~= 1.5e-3 light years. A size of the observable Universe part is 13e9 light years. 13e9/1.5e-3 ~= 1e13 times. A human size ~ 1e0 m. 1e0/1e13 = 1e-13 m ~ 0.1 picometers Atom radius ~= 100 picometers. Nucleus radius ~= 0.01 picometer. So, "Our direct physical measurements" or "Our planetary system" / "Observable Universe size" ~= "Atom or nucleus size" / "Our own size". Do you really think that one atom can describe the total human body according to its minuscule observation? So, any current astrophysical theory is not even a "first approximation", but "before zero approximation". Nobody can measure gravity or optics at a galaxy scale distance, we just stare to sunsplashes on a ceiling.

A smoking room. 1. Because "engineer" means "engine", and engines make a smoke. 2. Because engineers are serious and well-looking persons wearing smoking jackets. 3. Because engineers smoke in this room and play new gadgets instead of work.
