|Would guns, such as assault rifle, work in space?
I know the rounds would work, as explosives do not require oxygen, and they are air tight anyway - so the fireing pin would still cause them to detonate and proppel the bullet.
Would the firearm be able to withstand the pressure in space, there being no atmosphere? And what would become of the fired bullets, there being no gravity and so no bullet drop or loss of velocity?
In fact, due to their being no loss of velocity, would an air gun shooting from pre-filled gas cylinders work as effectively as a conventional rifle?
I know Russian cosmonauts packed firearms in the form of a survival gun, with three barrels, for flares, buckshot and rifle bullets, however that was a survival gun for after landing on Earth. I believe there is one on the new international space station.
I aslo found this pic, with the caption of a Russian space experiment, but I think it far more likely to be photoshopped.
