The next issue, is whether NASA will insist on another unmanned demo before putting a crew on board. Then a post flight evaluation, then the first manned flight. This could potentially put this until 2020 Q3. This would also put Space X a costly two spacecraft, possibly three, before commercial revenue starts flowing.

I thought I'd move an aspect of the SpaceX 20 April test failure implication over to this thread, to discuss what our perceptions of the relative state of readiness and likely mission times are.I didn't (and still don't) see Boeing's Starliner being ready this year for crew flight, and I'm not certain about their uncrewed flight either - that might perhaps be achieved in 2019 but I don't expect it before Q4, due to poorly-explained delays in dates so far. Following that flight I would guess at a 4-6 month gap to the crew flight. Whether the ISS schedule continues to push this towards being a long mission is beyond my guessing.Before SpaceX's test failure, my expectation was to see the first crew carried to ISS (on DM-2) in Q3 of this year. It's obviously really hard to know how much that will change but I would see everything pushed back by at least one Crew Dragon production cycle, about 3-4 months. Possibly more, but I would expect the delay to be 8-9 months maximum. Less than a year, so first half of 2020. Perhaps the delay will turn this one into a full-length mission too.So right now the coin is definitely in the air for which provider is most likely to make the first crew flight to ISS. My bet is still slightly on SpaceX first.
Mass numbers available online for the various capsules seem to be quite approximate, I'm more interested in mass during descent under parachute after a nominal mission. The numbers I've found seem to be more aligned with wet mass at launch. Naturally that would be less after a mission, with onboard fuel burned for the thrusters, and so on. IIRC Starliner also jettisons its heat shield and forward bay cover prior to parachute descent. If anyone knows more accurate mass numbers I'd appreciate that info. Starliner capsule mass ~18,000 lb (8,100 kg), diameter 4.56 metersOrion capsule mass ~19,000 lb (8,600 kg), diameter 5.02 metersDragon v2 capsule mass ~30,000 lb (14,000 kg), diameter 4 metersDragon is so much heavier because it has integrated its SM and LAS into the body of the capsule, and it also carries the weight of all its LAS fuel. I mentioned diameter because aerodynamics plays a part too, with the Dragon producing less drag because it's smaller. This is basically why Dragon has a 4th parachute. It's worth noting that all three spacecraft use parachutes of the same diameter (116 ft / 35.3 m), though with differing designs. Also, AFAIK all three use the same parachute system supplier, Airborne Systems. *edit* Side note: The crew part of the Soyuz weighs a lot less than the American capsules. As a side benefit of disposing of both the orbital module and the service module, it is only about 3,000 kg (2.17 m in diameter). It uses a single main parachute, also of 117 ft / 35.5 m diameter.
Orion capsule mass ~19,000 lb (8,600 kg), diameter 5.02 meters
Dragon v2 capsule mass ~30,000 lb (14,000 kg), diameter 4 meters

But all this was known
There will almost certainly be some sort of controversy with the first commercial crew flights, given the overall stakes with humans on board and the more purely commercial nature of the contracts. Moreover, both SpaceX and Boeing have had accidents just before, during, or after hot-fire tests of the thrusters to be used during a launch abort emergency."Somebody is going to be unhappy," Hale said of the Flight Readiness Reviews for the first crewed flights of the new vehicles. "I guarantee it. If it’s not one thing it will be another. There will be a contentious meeting and somebody is going to have to say, 'Well, I heard the story and I think we ought to go ahead.'""It’s potentially going to be ugly, and they wouldn’t have done that with Bill," Hale said. "If Bill were there and said 'I heard you, and I think the risk is acceptable,' the NASA workforce would have gone along. Now, they’ve lost that."

They seemed to be saying the modeling problems affected everyone. That doesn't necessarily mean they'll stop flying until the entire industry gets better at parachute modeling. We'll see if they say anything about it at the next NAC meeting.

One example of this being that the 4th parachute that was added was getting tangled/moving in unpredictable ways, if I recall... just like a three-legged stool always being stable, the behavior of three parachutes is easier to model. Four is another ballgame.
Boeing, NASA and the U.S. Army conducted exercises, known as mission dress rehearsals, for Boeing’s upcoming CST-100 Starliner missions to the International Space Station. This series of rehearsals at the White Sands Missile Range in New Mexico focused on the landing and recovery aspect of Starliner’s mission, and was one of three of Boeing’s formal dress rehearsals that took place over the last couple of weeks as part of NASA’s Commercial Crew Program.
ASAP doesn't set the number of parachutes. The spacecraft manufacturer and the Commercial Crew office set the number of parachutes.
Quote from: gongora on 09/08/2019 07:52 pmASAP doesn't set the number of parachutes. The spacecraft manufacturer and the Commercial Crew office set the number of parachutes.It is my understanding that increases the number of parachutes increases the safety rating. NASA does not require 4 parachutes, but they did design the criteria for safety rating vs LOM. Boeing and SpaceX are struggling to get every point they can to get to 140. If they go to 3 parachutes they will have to find some other item to improve to gain back the lost point. So yes, the 4 parachute system is driven by NASA.
NASA and SpaceX conducted a formal verification of the company’s emergency escape, or egress, system at Kennedy Space Center’s Launch Complex 39A in Florida on Sept. 18, 2019. NASA astronauts Bob Behnken and Shannon Walker participated in the exercise to verify the crew can safely and swiftly evacuate from the launch pad in the unlikely event of an emergency before liftoff of SpaceX’s first crewed flight test, called Demo-2.

That just spreads out the payments ahead of time because payment on delivery (i.e. live crew member arrival on ISS, live crew member return to Earth) would be too burdensome financially and risky for the contractors. As such, the government takes on the risk that one or both vehicles never will successfully or safely rotate crews through the ISS or do so late which might mean less operational rotations would occur (the cost per flight then would be greater).
If you interpret contract this way, then any contractor who hasn't delivered the final product also "failed at what they were paid to do", this include Boeing, twice (SLS core stage and Starliner) and Lockheed Martin (Orion), plus whoever the contractor is for the SLS GSE, plus Northrop Grumman (JWST), and many many others.

The fact remains: either (I) these schedules will balloon beyond 2026, best case (which so far hasn't been admitted), or (II) the attention (= money = manpower) devoted to this far more complex project, compared to D2's initial crewed capability, needs to be much, much larger than that given to Commercial Crew in the last 5 years. Or both.

Unless SpaceX has created Dragon 2 delays due to its Starship/SH program, Bridenstien's tweet is outrageous. Also, last time I looked, SpaceX wasn't exactly the only commercial crew provider. Are there similar tweets calling out other NASA contractors by name in this manner? If not, I think an explanation should be demanded. If, however, SpaceX has caused Dragon2 delays due to Starship/SH, then IMHO he has a valid point - provided he actually makes that point, instead of innuendo as currently. This smells of sour grapes.
(I) NASA is saying they'll land human on the Moon in 2024, which is much much harder than DearMoon, nobody is calling out this cognitive dissonance either
(II) There is nothing for Administrator to be concerned about, since D2 is already near completion, once it's completed the resources used on it can be redirected to Starship, so more manpower to Starship (later) and attention to D2 (now) is not mutually exclusive.
(III) You're ignoring the huge amount of knowledge and hardware they can port from D2 directly to Starship, ECLSS and suits for starters. For DearMoon, they can even bolt a few D2 capsules directly inside the Starship cargo bay.
(IV) You're also ignoring the fact that for DearMoon SpaceX wouldn't need the tons of NASA paperwork, they only need informed consent and FAA approval.
(V) There's also the fact that Starship has much more payload capability to play with, which means they can trade mass for complexity/cost of the life support system.
(VI) Additionally, Starship - the spacecraft - would fly many unmanned missions before having people aboard, unlike D2 which only has one test flight before bringing people onboard. This changes the risk calculation and mitigation strategy significantly.

I will note (correct me if I'm wrong) but no funding request for CC has ever been paid in full by Congress. My impression is they have released 50% (or less) of the funds asked for every time. To then complain about failure to execute (while giving SLS more than NASA ask for) seems pretty unfair.

I list two concerns that, according to D2's development history and SS/SH's obvious greater complexity, are either separately or concurrently inevitable (to summarize, 2024 is substantially delayed, more attention is being/will be given to SS/SH than CC, or both).You object I didn't take into account revenue permitting to circumvent both. I reply existing revenue was also used beyond the $2.6B public money award for the simpler D2, and yet... I also asked you some stuff about foreseeable revenues you chose to ignore in your new post, while not addressing my initial arguments or my rebuttal to your "revenue" idea.

I reply existing revenue was also used beyond the $2.6B public money award for the simpler D2, and yet... I also asked you some stuff about foreseeable revenues you chose to ignore in your new post, while not addressing my initial arguments or my rebuttal to your "revenue" idea.
And maybe Brindestine has a datapoint or two more than commentators here.
Oh, plenty of people (rightfully) are. But we're not whatabouting here, are we?
Friendly reminder that Congress cut commercial crew funding by more than 50% for the first 5 years! ($500M became $230M, $800M became $400M etc.) Meanwhile, SLS/Orion requests of $3-4B got $100M's added by Congress. Not all schedule slips should be created equal.
Elon still follows him. It's right there when you click on Elon's Twitter profile and then click on 'following'(Corrected a typo)

Under Jim’s account the message I get is “Followed by no one you are following”. Meaning Elon no longer follows him?

Elon follows 81 accounts, and Bridenstine appears in this list, so I believe he's still following him. Not sure why what you're describing is happening.Sent from my BBF100-6 using Tapatalk

“I am looking forward to the SpaceX announcement tomorrow. NASA is excited being partners with private companies furthering the goal of making human endeavours in space more accessible. Together we can move expeditiously toward return to domestic crewed spaceflight and a permanent presence at the moon and beyond.”
Guys, can we remember for a minute that Jim Bridenstine is a real human being who has been regularly grilled/roasted by Congress, the press, the President, the Russians and whoever else since he started his job because the USA doesn't have an operational crew launch capability. I read his tweet more as "Sure starship is awesome, I just wish they could finally get crew to ISS so all these jerks will stop busting my balls." His tweet rubbed me wrong too and seemed unfair/undiplomatic, but it's an understandable sentiment from where he sits.Sent from my GM1917 using Tapatalk

"Enthusiasm" is the key word of the tweet. While Bridenstine seems to be scolding SpaceX like the frustrated parent of an unruly child, what really has him upset is that the public is much more enthusiastic about Starship than Commercial Crew or Artemis.

Apart from the generally classless phrasing of the statement it’s also telling that SpaceX is further ahead on commercial crew than Boeing but only SpaceX was tagged in the tweet. If Bridenstine was aiming it at all space contractors, he should have tagged them. SpaceX has at least sent a Crew Dragon test article to the ISS.
Her error is in extrapolating <50% funding for 2 years to 5 years.
I completely agree with his statement though. When the last time SpaceX made any mention of Crew Dragon? I know when a part time employee who cleans the bathrooms is hired at Boca Chica before I know any progress on Crew Dragon.

Update from Bridenstine spokesperson: No further comment is expected explaining the NASA administrator’s tweet about today’s Starship presentation or what specifically he would like to see SpaceX do to hurry commercial crew.

When the last time SpaceX made any mention of Crew Dragon? I know when a part time employee who cleans the bathrooms is hired at Boca Chica before I know any progress on Crew Dragon. SpaceX mentions Crew Dragon progress regularly; it doesn't mention it as often as Elon tweets about Starship because it's not progressing as fast. Commercial Crew has a lot more factors acting to slow it down than Starship, and that's reflected in the number of announcements we get.
The pushback against and removal of propulsive landing eliminated Crew Dragon as a component of SpaceX's Mars and moon plans. Did this also diminish some aspect of 'enthusiasm'? Yes, probably. With Red Dragon off the table, SpaceX accelerated alternatives. One of these is standing 50m tall and reflecting the Texas sky.
>Unclear what could be done to improve Crew Dragon engineering or schedule.
NASA's Inspector General has apparently had enough of meddling by CongressOn Tuesday, NASA Inspector General Paul Martin wrote a rather extraordinary letter to the US senators who determine the budget for the space agency. In effect, the independent NASA official asked Congress to kindly not meddle in decisions that concern actual rocket science.>

It’s time to deliver.”That's just.... wow. Really?Why in the world would you piss all over SpaceX's monumental achievement? This could be the inflection point in history where space travel becomes more routine and accessible to the masses. If history bears this out, Jim will have an ignominious black mark on his name and tenure as NASA administrator.Stay classy Jim.
This really feels like NASA is jealous of SpaceX for getting most of the attention these days.
