In 2015, technicians entered the retired Space Shuttle Endeavour to remove the water tanks, with the goal of reusing these tanks on ISS.
The space shuttle Endeavour is retired and on display at the California Science Center, but it's still contributing to the space program.
NASA engineers are working this week to remove four tanks from the shuttle for use as potable water storage on the International Space Station.
Looks like a strange idea to reuse worn equipment as trivial as a water tank that is exhibited in a museum, when whole rockets are built brand new for a typical flight.
Are these tanks somehow special and unusually expensive to make to justify such an idea? If they are just metal cans as I envision, the only reason I could imagine would be a "symbolic meaning".
