It says that Skylab and ISS have the same habitable volume. That is way wrong! ISS is about 2.5x larger.
They are talking about the volume that is habitable. Skylab had 12,750 cubic feet of habital volume and the ISS currently has 13,696 cubic feet. So ISS only has about 7% more volume. Not 2.5 times the volume. As a structure in space the ISS, because of the solar arrays, has a lot bigger footprint.
Wikipedia says that the ISS has 29,600 cubic feet of pressurized volume. And of course it is much larger than Skylab! http://en.wikipedia.org/wik…
That is total pressurized volume not the habitable volume that do not include things like storage lockers, consoles, furniture, etc..
Skylab had a lot of habitable space that was mostly empty. That was mostly a result of the main laboratory area being a converted third stage fuel tank. There were a couple of floors at the bottom of the tank with the galley, shower, sleeping compartments. Then a big empty space at the top with a rink of storage lockers that was great for aerobatics.
I doubt some of those numbers as well. ISS only slighly more “habitable space” than Mir? ISS has ~2.5 times the pressurized volume of Mir, so if the fraction of “Non habitable pressurized space” (equipment etc) is roughly similar, there must be a bigger difference.
And even considering Skylab was basically an empty fuel tank, the cited amount of cubic feet “habitable space” is still more than what wikipedia lists as “pressurized volume”.
Oh and did anyone else notice the “perpetual sunlight on one hemisphere of the moon” fail? 😀
The Moon Space part of the diagram really chapped my hide. That’s just what we need to spend money on, religion on the moon. Really? How about a DNA pool of all of Earth’s current creatures instead. That would make far more sense. As far as a trash dump, you’ve got to be kidding. We need exploration and then a proper base and colonization efforts.
Just imagine, in 7,000 years after we have gone, alien intelligence finds a Torah on the moon and wonders… ‘all that effort for this?’
How ironic if our epitaph is formed by superstition, by the part of our culture that has ever resisted our progress
