If they have time, astronauts and cosmonauts will look to plug the leak or close the hatch to the leaking section of the station. (That is how they dealt with a minor leak in the station’s PrK module for a number of years, and it basically worked.) Remember, though, that this is the worst-case scenario, and our crew will run into a hard deadline. Once pressure falls to around 490 mm Hg, NASA says, critical systems risk breaking down. Astronauts could suffer hypoxia, oxygen deprivation so debilitating they could become delirious. It will be a heart-wrenching call, but if nothing else can be done, the crew will need to go to their crew vehicles and leave the ISS.
“党看干部主要就是看肩膀能不能负重，能不能超负荷”“我们做人一世，为官一任，要有肝胆，要有担当精神”“要拎着乌纱帽干事，不要捂着乌纱帽做官”“‘为官避事平生耻。’担当大小，体现着干部的胸怀、勇气、格调”……关键时刻站得出来，危急关头顶得上去，折射的是政绩观，彰显的是党性和作风。
