Do you grasp the cost of losing a crew on Soyuz in a political sense?
do you grasp the cost of failure in a political sense?

What is the political cost _to NASA_ if one of the many Russian Soyuz launches fails?
How about if the first flight of the US Commercial Crew fails?

The Administrator says they are months away but assures everyone that the delay will be less than a year.Really?

AS I said, I initially thought the delay was completely unjustified. I no longer think that. that belief is based on what I have heard and been told by people very close to the NASA and contractor side.So much so that as I said I pulled an op ed that was going to print this coming Sunday in a major Washington based US newspaper.Safety is thing...the most important aspect of it is listening to well voiced concerns raised by thoughtful people. NASA has a history of not doing that. I am tilting to the possibility that they did here
the reason you haven’t seen anything on here/twitter about them doing parachute drop tests recently is because there was a chute failure and that test article no longer exists after a ballistic impact with the desert floor.
Interesting discussion on facebook in this comment thread Specially with this commentQuotethe reason you haven’t seen anything on here/twitter about them doing parachute drop tests recently is because there was a chute failure and that test article no longer exists after a ballistic impact with the desert floor.I wonder how legitimate is this statement but certainly would be one hint at those "issues". What I certainly don't like about this approach from Bridenstine is that he is only saying "no" but not saying why and when he is asked he only says that "there have been issues". The question is "What issues?!". If what this guy said on facebook is true, then hell, yeah, I'd say that's a good reason to stop a few months more and take a look at it but saying "there have been issues" without giving some perspective of how bad they are is useless.

If you are going to say this, I'd appreciate it if you'd fill in just a bit of detail in L2I think part of problem with this implied delay is that Bridenstine could have included a very brief explanation of any supposed issues. Something like: "We are still looking at the reef cutters because one of them did not work fully during launch $XYZ". The fact that he did not leaves open the possibility that the delay is simply manufactured for other reasons.I urge you to fill in some detail too, for the same reason.
adding a 4th parachute?
I call BS on this one.
Everything I have read points to an extremely small issue being blown out of proportion regards the "parachute failure". But I have to give TrippleSeven his due, if there really is a serious issue, I wish NASA would make it public and quickly so this divisive debate can be put to bed.
Quote from: TripleSeven on 11/30/2018 06:39 pmdo you grasp the cost of failure in a political sense?There in lies the problem. Politicians view themselves as being more important than anybody else and their views have more weight even if they are contrary to engineers, scientists, and people with common sense.Edit: I guess I feel the need to expand on this. I believe that politicians should give NASA goals like explore the moon or asteroids etc. And then step back and let NASA do its job without trying to micro-manage NASA.
