More like "300 points of success" :)

• guenthert 5y ago
  I find it difficult to comprehend how much a risk they were taking. Documentation of some tests is publicly available; it's even mentioned that they found problems and had to partially redesign (and supposedly re-test). If a bolt (or rather one quite like it) has been tested successfully 100 times in the expected conditions, chances are it'll work when needed, but I get a sense not all of those parts in the 300 single points could be tested that often (material cost, time, availability of sufficiently large climate chamber capable of simulating outer space condition). Were there actually parts too expensive to test even once? Is JWST sailing on prayers?
