1. Fe is much more common element than Cu, Cr or V. An Earth-like planet mostly consists of O, Si, Al, Fe. So, more chances to meet and use Fe than anything else. 2. Terrestrial non-Fe species are worms, arthropods and molluscs. I.e. small (except squids and Kthulhu) archaic lifeforms appeared when there was much atmospheric oxygen, with primitive oxygen transport, living mostly in water, with primitive neural system. So, more probably that reasonable aliens' blood would be based on Fe. I.e. some kind of brown color.

It's just a usual cube-shaped star. While it rotates, we can see it either from faces, or from edges, or from vertices. So, its brightness varies. It's an extraterrestrial Minecraft star.

#3. Probably he would get his flesh been sucked into the hole in his glove and partially gluing up this hole. That would make air stream additionally unpredictable. Just press you hand to a vacuum cleaner tube. #5. We don't know how long was his life after the return. Maybe, the scenarist just omitted unessential particulars. Mark spends all his time in a small room covered with rotting wastes - that means, full of waste gases: methane, hydrogen sulfide, etc. As his haven't been suffocated, we can presume that his air cleaner works fine and removes even low quantities of flavorless gases such as methane. Then why didn't it clean out the hydrogen causing the explosion?

I have read in late 1980s: 80 billion people on Earth since the beginning till now. So, ~90..100 billion.

Yes. And basically a real-world "FTP part" is a plant about a square kilometer with dozens of columns.

Accident with Bondarenko took place not in a spacecraft, but in a soundproof decompression chamber during the training.

Anchor capstan and a 500m long thin cable. Hovering, putting an acnhor, flying 501 m away, landing, crawling to the anchor - coiling the cable onto the drum. Oh, yes, and a pair of toy wheels to show that this is a rover. Was that required by the competition conditions?

Btw, as far as I know, Fischer-Tropsch process doesn't produce simply a pure kerosene. It produces a crazy mixture of hydrocarbons, mostly petrol, diesel, propane/butane, etc. Kerosene fraction is just a minor component. (Majors are petrol and diesel fractions). So, F-T doesn't eliminate an oil refinery plant, it just provides another raw material for it. Instead of desalinated oil you use a F-T synthetic mixture, with the same need to distillate and rectificate it into different fractions. As only kerosene is useful as a rocket fuel, so anybody who makes the kerosene by Fischer-Tropsch, must build rectification columns, purifiers, other refinery stuff. This doesn't look much as real ISRU, this is more like an extrakerbestrial industry.

The most toxic and dangerous are dioxins. The most deadly is water. Every year it kills many thousands of people. There is no another such deadly substance. You see! Water kills not only by presence, but even with absence! Absolute evil.

In this animation they use multiple SRB around the Orion's body.

Muon is 200 times heavier than electron, and also can orbit the nucleus. Due to its mass, its orbital radius is significantly less, so "nucleus+muon(s)" atom is more compact than a "nucleus+electron(s)" atom. So, nuclei are much closer to each other, and it requires much less energy to collide them and make them to merge. Neutrons presence/absence is not involved here, just a lower energy and temperature requirements. This theme was popular about 25 years ago, but still without no visible progress.

Maybe "Throttle Controlled Avionics" is more useful in this case? http://forum.kerbalspaceprogram.com/threads/107802-Throttle-Controlled-Avionics-2-3-0-1-0-4-Continued

Who cares that water? They have revealed that Mars is habitated by lovely maidens in chain-armor camisoles appealing to brave Earthlings to help. That was the real aim of all Martian programs, the water was only a cover-up.

A brief summary: "Exactly no Mars landing before 2040."

Would like to draw your attention to the launch position. It's on the same ground level with VAB. So the carrier vehicle doesn't need to climb somewhere - rather than at in-game KSC, dangerously tilting the rocket. Engine exhaust is evacuated using just a level difference between the launchpad and the ravine at its side.

Any building is just a structurized region of space, a grid of potentioal barriers. Different sub-regions (in human slang - "rooms") are separated by (electromagnetic) potential barriers (so called "walls"). The "wall" which prevents you from transition into the state with lower potential energy is also called "floor". The "wall" which prevents some objects with higher potentional energy to enter you place is called "ceiling". Why to structurize any space larger than several km in height and several km in diameter at all? Population density of a city, say, 3000 humans/km2. Binocular vision range - several meters, so a ceiling of a large atrium (say, of a large cathedral) is on "visual infinity" and doesn't "press" you visually from above, as also the sky doesn't. So, we can slice a city into layers each 100 m height with virtual "sky with clouds" and city people won't see much difference. In this layered city we have 100·1000 / 3000 = 33 m3/human. The biological studies of 60s gave a result: a spaceship would provide 27 m3 per human to let this human feel enough comfortable in long flight. This number is close to what we have gotten above. So, let it be 50 m3/human to feel more or less happy. One billion people = 50 bln m3 = 50 km3 501/3 = 3.7 km. So, a building 5x5x5 km is enough to let one billion people live as in usual city. How many people anybody can imagine to use those Dyson spheres and other megalomania?

Lunar orbits are unstable. Low orbits due to the mascons, high ones - due to the Earth. So placing a rock as a satellite of the Moon means that you would require a good home insurance.

Fly like a sir. © LZ 129 Hindenburg had an aluminium grand piano onboard. Why the spacecraft may not have at least at armchair?

Diameter of Ceres = 950 km, Moon diameter = 3470 km. I.e. Ceres is 4 times less than Moon. Also, its mass is about 1.5% of Moon mass (9.4·1020 vs 7.4·1022 kg). And this is ~30% of total asteroid belt mass. Ceres, Vesta and Pallas are in total 2.5% of Moon mass and they contain 50% of full asteroid belt mass.

About a year ago somebody here suggested: electromagnetic projector or blast which drains off all batteries inside a radius, disabling crafts and allowing to capture them.
