"Earlier this year, NASA elevated the leak to the highest level of risk as the rate of air escaping from the module had doubled from one pound of air per day to a little over two pounds."
How, in a gravity free environment, do you weigh air?
I would assume - knowing literally nothing about it - that the internal atmosphere is constantly monitored. That monitoring detects a change and a lowering of 'air' and so releases 'air' from a reserve and it is the weight of _that_ which is the measurement?
- jqpabc123 2y agoHow, in a gravity free environment, do you weigh air? You can calculate loss of air mass (not weight) by measuring pressure loss within a known volume (i.e. a space station module). This pressure differential corresponds to a certain volume of air which in turn corresponds to a particular weight back on earth.
