Using plastic or rubber or something similar and transparent be inflated with each layer having a increasing pressure lessening the strain on the containing material? When one or two layers fails the ...

The ISS uses a Sabatier reactor to recover oxygen from carbon dioxide. This has an output product of methane. I would imagine that most methane that enters our atmosphere at ground level only reaches ...

I heard that the Galileo spacecraft sent Galileo Probe into Jupiter, and it reported temperatures reaching 153 degrees Celsius. The question is, when you send a probe crashing into a planet that has ...

Is this primarily done analyzing the Voigt profiles absorption bands on background of stellar spectra or on re-emission bands of atmospheric compounds? Assuming Pluto's atmosphere behaves like an ...

The Wikipedia page for the International Space Station says that it has a fairly Earth-like, sea-level atmosphere: 21% oxygen, balance nitrogen at 101.3 kPa. Supposedly it's because a pure-oxygen ...

I need to build a drag model for my rocket optimization program and I stumbled upon by the following formula: $CD = CD_c(M)$, $K_n < K_{nc}$, $CD = CD_{fm}$, $K_n > K_{nf}$, $CD = CD_c +(CD_{...

In 2016 a large ice deposit has been found within the Utopia Planitia region on Mars by the SHARAD instrument on board of the Mars Reconnaissance Orbiter. The thickness of the deposit ranges from ...

I recently watched the series Altered Carbon. In that series, they showed a floating space station called "Head in the Clouds". There is a blue sky here, even clouds. This would imply a height of &...

What weight of Martian soil can be supported by the top of an inflatable habitat pressurized at Earth's atmosphere? While habitat's shape is a huge factor, this has 20 meter modules, semi-cylindrical ...

I am just watching Space Race part 3 and the cosmonauts just got their first view of Wostok. The scientist who designed the retrorockets told the soon-to-be spacemen that the rockets would have to be ...

The Thumba Equatorial Rocket Launching Station is operated by ISRO for launching sounding rockets because magnetic equator passes through it. Equator gives additional velocity, But what advantage ...

For cyanobacteria metal ions like K+, Mg+ and other essential nutrients like phosphorus are vital for growing and to expand. So they could only thrive in the clouds of Venus if at least metal ions ...

From what I understand, Venus's upper atmosphere is much more habitable than its surface, with a temperature and pressure that humans could tolerate. However, lack of oxygen and sulphuric acid would ...

Many people would like to know if any form of life could survive anywhere in the atmosphere of Venus. Researchers have simulated conditions on Mars and found that after a month some cyanobacteria ...

According to Wikipedia: Venusian clouds are thick and are composed mainly (75-96%) of sulfuric acid droplets. These clouds obscure the surface of Venus from optical imaging, and reflect about 75% ...

I've read that on Mars you lose 30% of your heat through convection and 70% through black body radiation. (The much lower amount from convection due to the tenous atmosphere vs. Earth.) http://www....

I am making an exoplanet for a game and was wondering whether a planet without an atmosphere (or at least with a very weak atmosphere) could support caves that do have an atmosphere, or whether the ...

The title refers to the promotional slogan "What happens in Vegas, stays in Vegas." The question How much CO2 would city-to-city rocket flight produce compared to airliners? seems to be focused on ...

Saturn being at 10 A.U. means sunlight on Titan's cloud tops is about 1/100 that on Earth's. That's 4000 times the illumination of Earth's moon. Titan's atmosphere is described as opaque smog. If ...

I am wondering - what is the nature of the atmosphere in and around the transition to space at the Karman line? It is not difficult to find references using terms like "in the atmosphere" and "out of ...

The NASA Science video ScienceCasts: A Display of Lights Above the Storm shows several examples of Transient Luminous Events (TLEs) (Upper Atmospheric Lightning) being filmed by high-sensitivity ...

I know that on the forthcoming SpaceX attempt at sea landing the first stage, they have added hypersonic fins to the first stage. I was curious as to what altitude transonic compressibility is an ...

OK. Hear me out. I know that blimps float because of the buoyancy of air, and there is no air in space. But think of the way a boat floats on the top of water even though the material that the boat is ...

I am currently working on a college senior design team that is looking at developing a small modular habitat that could sustain plant growth. These small modules would not include humans, so we only ...

When we think of terraforming a body in our galaxy Mars gets lots of consideration as the closest potential body. But what about the Moon? It is currently beyond our ability to add an atmosphere ...

The atmosphere of Venus contains strong winds and is said to have a "super rotation" because the atmosphere (above a certain altitude) moves faster than what the ground does. No one can disagree with ...

The air on Earth is about 20% oxygen and about 78% nitrogen. Best case, there seems to be sufficient oxygen (in water) to support colonization in the polar ice caps. What about the other 4/5 of the ...
