  • 您认为该商品的优点是,I''m about to run out of credit https://contraloria.bcs.gob.mx/stmap_24ssxciv.html?risperdal.levitra.buspar ibuprofen saft baby Then there’s the fact that NASA has to be as stingy as possible with these missions. It’s not just about money; the weight of the extra fuel needed to ramp up a spinning portion of the ISS, and maintain that spin, could be used for other, more mission-critical things. And once the ISS is spinning, how do we interact with it? Assuming we don’t want to have to match its rotation to dock, we’d need a variable-speed airlock to allow humans and objects to move from the stationary to rotating portions of the station. A seemingly simple innovation leads to dozens of small, expensive little problems that need fixing.
