It is incredibly difficult to make things work well and fast without running into problems relating to these two issues alone... | |

When everything associated with space vehicles is expensive, rigorous testing is required to minimize the chances of equipment failure & financial loss. Rigorous testing just costs lots of money. Also people are always pushing the envelope to achieve higher productivities. It all adds to the costs. | |

| Dec 11, 2015 at 18:15 | comment | added | Brian Lynch | Testing for space flight hardware is expensive and demanding simply because it needs to be so much more robust and complete compared to any other industry (including things like aircraft and nuclear power). The reason for that is because you can't exactly go fix something in space -- Hubble and ISS are exceptions but in general you don't have much of a chance for repair and servicing (for now). | |
