This article needs some work.
First, helium is not a "non-inert gas" - it is inert, so it is a non-inflammable gas.
Second, wasn't it was already announced yesterday that the June 1 launch date is out, and launch has been rescheduled for June 5?
And, frankly, this business of "studying the issue with software" doesn't leave me with a good feeling. If they completely understood the situation, then it would not be leaking. There is a problem with one seal. Why? What will happen to that seal when it is subjected to vibration, stress and temperature changes during launch and while in the space environment? And, will that cause problems with other seals, in addition to this one?
Yes, the leak rate needed to strand the astronauts in space is much larger. But, how do we know what the limit is for the leak rate for this craft, given that it is already having a problem?
Let's not have another life-ending "mishap" that could have been avoided by actually dealing with an issue instead of "analyzing it away" with a computer program involving a lot of assumptions. We do not have a great track record with "assumptions".
