On December 9, NASA began what is either an impressive engineering test or a classic example of world-class larking about. At the space agency’s Marshall Space Flight Center in Huntsville, Alabama, engineers are crushing an enormous can by subjecting it to almost one million pounds of force. This may seem like a party trick that’s gone out of control, but there’s a serious reason behind this … or so NASA says. The crushing is part of the project to design the fuel tanks for NASA’s Space Launch System
(SLS), which will be used to launch the Orion spacecraft and deep space missions.
