open an empty jar on a space walk, put the lid back on, and upon return to earth, whats in it?

What's in the air in space?? If an Astronaut opened an empty jar on a space walk, waved it around, then put the lid back on, upon return to earth, what would the analysis of the contents contain??

    You'd have to keep the lid off the jar when you took it out of the space station otherwise the jar might explode due to the higher pressure of the air inside to the low pressure of the air outside of course it would depend on how strong the jar is.

    When you take the jar that has very low air pressure into a 1 atmosphere environment, it might implode (then again depending on the strength of the jar it might not).

    Now the problem is when you take the lid off the jar to analyse the contents you'll find it hard to take the lid off due to the increased pressure outside the jar from what's inside. Once you get the lid off air from the surrounding environment will rush into the jar so all you'll end up analysing is the air in the lab.

    Now if what you're really trying to ask is what's the air like where the ISS orbits, it's mostly light weight gasses like hydrogen and helium as the ISS is actually orbiting in the very upper layers of our atmosphere, it's not complete inter planetary space, the ISS is in low earth orbit and its height (376-398km) is in the exobase of the earth's atmosphere. At that altitude the gas molecules are extremely far apart so in your jar there's probably at most one or two hydrogen or helium molecules.

  • Nothing would be found in the jar, because the vacuum of space is much more perfect than any vacuum we've created here on Earth. The lid would be hard to get off because of the atmospheric pressure pushing in on the vacuum.

    Could then save electricity by using jar as vacuum cleaner.

    I in no way try this interior the traditional flow. i will purely do in some case which contain a million) the guy would be previous. 2) in case of 70 % bodily disable. 3) in case if there is rush interior the bus.

    It would contain nothing... the Jar (if it was strong enough) would be a vaccuum. (If it wasn't strong enough - it would simply implode.)

    But how do you analyze it without taking the lid off?

    A vacuum. An absence of matter.
