Nothing to do with education; it’s all about operating procedures. Hubble has a large and well funded team behind it that generally operates on much longer timelines. Everything is engineered and documented to a tee. Hubble mission spans around 30 years now, from concept and until today; very possible that for some people, Hubble is the only thing they experienced in their profession. Obviously such measures would be very much impractical outside of NASA.
