[Sunward] The Venusian Glider; can it really survive the Venusian atmosphere?
Hi TITANs, flats and other H+s. I was reading the Sunward rule chapter and in particular the new morphs section, and I was left wondering if the Venusian Glider morph really could survive in Venus' (upper) atmosphere (in the lower, it would die in seconds). There are 3 factors which could affect the survivability of a morph in the Venusian atmosphere: -Temperature. Is the temperature at the standard flying altitude of the Glider around ~20 C? That would be quite the coincidence, especially considering the weird mix or chemicals it is made of. However, maybe the habitats are built so that the surrounding temprature is around 20 C. -Pressure. Either too low or too high, if you're not just at the right altitude. Again, maybe the aerostats' location is chosen for those conditions, but it looks difficult to have both 1 bar of pressure *and* 20 C at the same time. That would be quite the coincidence. (And yes, that's how thing are on Earth's surface, but the conditions are entirely different.) -Toxicity and corrosiveness. A good amount of the Venusian atmosphere contains sulfuric acid droplets/vapors. That's nasty for the complexion, and even though the respirocytes alleviate the need for breathing, having acid-resistant lungs and toxic filters could really save your life if you unwillingly breathe a bit of that nasty mix. I believe the Venusian Glider needs quite a few mods before being Venus-proof.

It is indeed quite a coincidence, and it's true, which is why Venus is such a good choice for colonization. See http://en.wikipedia.org/wiki/Atmosphere_of_Venus for basic info.

That's true, and currently Venus gliders need some sort of air supply like an oxygen tank or the oxygen storage augment. When the terrforming of Venus' upper atmosphere is completed, it's going to be breathable by anyone with filter lungs.

Actually, it shows this: Height (km) Temp. (°C) Atmospheric pressure (x Earth) 0 462 92.10 5 424 66.65 10 385 47.39 15 348 33.04 20 306 22.52 25 264 14.93 30 222 9.851 35 180 5.917 40 143 3.501 45 110 1.979 50 75 1.066 <<< Good Pressure, temperature too high 55 27 0.5314 <<< Good temperature (a bit high, summer-like), pressure too low. 60 −10 0.2357 65 −30 0.09765 70 −43 0.03690 80 −76 0.004760 90 −104 0.0003736 100 −112 0.00002660 Thus, the coincidence actually isn't there (not too far, but not quite) So they either need some high-temperature protection, or low-pressure. My guess is that .5 bars isn't really too bad and is easier to adapt to than 75 C.

They need skin protection against corrosive agents too, and stuff to protect the lungs and trachea in case of accidental inhalation.

0.5 bars is a perfectly reasonable pressure, it's equivalent to an altitude (on Earth) of 3 miles, which is an altitude that most humans can easily tolerate. I'd expect that all visitors in biomorphs might need a shot to help them avoid altitude sickness due to lower air pressure, but that's it the only problem. Also, I'd say that basic biomods would take care of altitude sickness at any safe altitude (ie, up to about 4 miles).

Once it's atmosphere is terraformed, this won't be a problem.
