“We’ve trapped ourselves in a vicious cycle of spending a lot of money on mission assurance, which makes the assets incredibly expensive, which means the launch vehicles that support them need to have near certainty,” Griffin said. “What we should be thinking about is the overall cost of the architecture we deploy.”
Tugger wrote:Oh yes, ULA definitely deserves attention. But of course they have been "boring" and basically 100% successful for years now and not trying anything new like SpaceX. But that doesn't or shouldn't take away from the the awesomeness of the rockets they have.
My favorite is the Delta IV Heavy. There is something awesome about how it looks taking off, the engines and thrust pattern... . beautiful:

I agree ULA has a near spotless launch record, though I wonder if they’ll begin to push a faster launch cadence in response to SpaceX, and I wonder further what effect that might have on their reliability. None, I hope.
Like I said earlier, I’m glad they have some competition and I hope the raise their game.

parapente wrote:Yup Delta4 heavy is a phenomenal rocket with (I believe) a 100% safety record.I note Spacex love to quote power stats to LEO as it's suits their engines.They turn into powder puffs in a vacuum.If you look at what the D4H can take into Geocentric orbit it's nearly as powerful as the FH.
Just that Elon always wind the PR wars!

The engine is the most expensive part of the rocket, accounting for two-thirds of the cost of a booster, Bruno said.
ULA doesn't have a customer yet for its Vulcan, but Bruno said the company was in a discussion with a number of prospects and said any customers will pay for the first launches.
"I will not fly a car," he said,
Prior to the vote, the company said its operations would not be affected by a strike. ULA confirmed that in its May 6 statement, saying it would “implement its strike contingency plans while focusing on meeting its commitments to our customers.”
While this strike is happening, ULA will need to find another way to get its rockets made and up into space.
An IAMAW representative says that the ULA employees have two main issues with the contract ULA proposed. One involves stipulations on travel between the two launch sites. ULA doesn’t launch out of Vandenberg very often, so the company maintains just a small workforce over there. So whenever there is a Vandenberg launch, employees from Florida are called to travel to Vandenberg to help with mission operations. Originally, employees only had to be in California for 30 days at a time and were then rotated out if needed.
However, IAMAW claims the new contract would allow ULA to call Florida employees back to Vandenberg after they had already returned home from a 30-day stint. “If you come back, they can send you back again,” Johnny Walker, a representative for IAMAW in Cape Canaveral, Florida, tells The Verge. “The family life is gone, and you can’t say no.”
Additionally, IAMAW says the contract gives ULA the option to sub-contract any job that it wants, meaning a full-time employee’s work could be given to an outside company at any time. The union sees that as ULA’s attempt to reduce the size of its workforce and pay lower wages. “Our guys have certification beyond belief,” says Walker. “We have a perfect record for launching rockets. We never have lost a rocket or had a failure. We were part of it being successful, and now they’re turning it around and treating us like dirt.”
Another sticking point was subcontracting. IAM members fear that ULA could use that to cut full-time jobs, according to the Orlando Sentinel. ULA, however, said it has no intention of displacing workers via subcontracting and it guaranteed that in writing as part of its “last, best and final offer.”
Boeing recently conducted a hot fire test for their low-altitude abort milestone for the CST-100,” noted a member of the ASAP panel. “And there was an anomaly on that test that we need to better understand in terms of its potential impact on the design and operation and the schedule.
“And so although there’s a lot of interest in this issue, Boeing has asked for some additional time to step back and understand that a little better.”
“We can expect some uncertainty [in] their near-term schedules at least for the Boeing provider while they go through that,” noted the ASAP. “And then we should have a much better sense of the Orbital Flight Test and the Crew Flight Test for that provider.”

parapente wrote:Odd thing ( to me) is that the BE-4 is designed from the ground up indeed inception as a reusable engine,yet here they are planning to throw them away each time (Unlike Blue Origin).Makes no sense to me,but clearly does to ULA (Boeing) who are of course doing exactly the same thing with the fabulous reusable Shuttle engines on their ever delayed SLS.Ah well.
It was my vague understanding that they were planning on some degree of reusability, eventually. They might be developing a system to jettison and recover the engines?

Any words as to what the apparent mechanical problem was from previous attempts? Odd to see an already charred Delta IV sitting on the pad.

We will see how this delays the program but clearly SpaceX has a chance to steal Starliner's thunder. Musk's showmanship will be out in full force soon.

NASA administrator Brindenstine mentioned four times "a lot of things went right"
Too much propellant was burned due to an error in tracking elapsed time
When it was noticed the spacecraft was in between comm relay satellites, so there was a further delay to response.
Essentially they lost too much time in responding and are chalking the error up to an automation failure, if the vehicle was crewed they insist they would have made it to ISS.
So in short, NASA needs a better onboard clock, do they have more than one in the vehicle?
If they do, what happens if they disagree, or is it like the MAX, they never thought of such a scenario occurring???
Delays.... they say too early to know
Does anyone review any automation software at Boeing? Who makes the clock?
aumaverick wrote:I hope the next flight is crewed so we can get back to some old school astronaut flying. I really liked Bridenstine's response noting every Shuttle mission was crewed, even the first docking mission with the ISS. Automate all you want, but its time to get back to putting suits in ships.
