Not really. They are putting experimental hardware into an environment that is not well understood. It is also being done by very public facing organizations with very large budgets. They basically have to guarantee that they will deliver what they say they will deliver. From a public relations standpoint, it may even be easier to justify a complete failure than an 80% success since a string of 80% successes will look like incompetence while a few complete failures are quickly forgotten.
