Some time back we had a discussion going about SpaceX CCtCAP milestones and it wandered off into a political discussion and the mods decided to move the whole thing to Space Politics. I can't even find it there.Boeing has been very public about its milestones but SpaceX has been silent. NASA has stated that things are progressing but nothing definitive. Some of the milestones should be easy to observe like #6) Propulsive Land Landing Test Complete. Wouldn't someone see this at McGregor?Which milestones are known to be complete?{snip}
So I guess we can take Chris's NAC chart as definitive up to end of November 2015. So I see rockets4life items 2 & 3 but 7 is in November. And I will create a new column for adjusted target dates. As for The Man In A Can's post, only 3 items are clearly stated as completed, a second CDR (4), Docking System Qualification (5) and Parachute test which I will take to be item 11.
I've been trying to find the original list of milestones from NASA, because I want to add descriptions. Can someone provide me with the link?
Here is the milestones chart as of march 2016 posted on twitter by Jeff Foust and reported by Sesquipedalian on the commercial crew schedule thread.https://twitter.com/jeff_foust/status/715552131323994115EDIT : Corrected a mistake about who posted it

Compared to what was reported last November the crewed demo mission shifted no less than eight months to the right, to august 2017.The interval between the unmanned flight and the in-flight abort test is IMO unrealistically tight (just two months), so I expect the in-flight abort test to shift to the right. Which means the crewed demo mission will also shift to the right (again). I fully expect for it to eventually shift into 2018.I also expect similar shifts to happen for CST-100. IMO their first crewed mission will also go into 2018.

If you talk to engineers actually doing CCtCap work, they all say add another 17 months for Boeing and 19-20 for SpaceX, that Boeing flies in 12/2017 followed by SpaceX.Does anyone actually have a CCtCap milestone update? The last I have is McAlister's July 2015 Commercial Crew Status. Back then, Boeing had completed only 4/23 of its CCtCap milestones and SpaceX only 1/18. I note above graphic that shows Boeing and SpaceX have plans to complete a great many milestones throughout 2016. But then SpaceX said it would complete the CCiCap inflight abort test by December. Here we are, in May, and SpaceX is now officially over two years behind on CCiCap Milestone 14. Maybe the third anniversary will be the charm? In any case, after the delays of COTS, CRS, and CCiCap, what the CCP companies want to do, and what they in fact do don't match-up very well, at least for SpaceX.

^ This is very frustrating to learn, but I'm glad some reality has been injected into the conversations around here to counter the hype. I really wish SpaceX would be realistic about their product delivery dates, it has knock-on effects for Red Dragon and their long term goals. Why even mention 2018 as a possibility if the are so far behind on getting Dragon 2 in any configuration off the ground?
Red Dragon is arguably easier than Crew Dragon (both v2) because it doesn't need to be human rated and have life support.
Jeff Foust reported in this article that SpaceX has completed 8 milestones so far.

The article also refers to that same March NAC slide still having the SpaceX dates with the uncrewed test flight in Dec 2016. Apparently the CCP Major Partners Milestone, also from March, may be the most updated with SpaceX uncrewed test flight of May 2017 as woods170 noted.Quote from: woods170 on 04/01/2016 07:18 amAnd as expected the uncrewed mission of Dragon 2 to the ISS has shifted some five months to the right and is now thoroughly in 2017.

IMO their first crewed mission will also go into 2018. Looking back on the milestone dates I've seen, it seems that 2 months has consistently been the interval between either uncrewed and crewed for Boeing and uncrewed, in flight abort (once they decided to use the flight test capsule), and crewed for SpaceX. I think these obviously assume all goes well and are spaced for the requisite processing time between each. I think its a fair, if tight, interval if all goes well. However, even if things go well, I could imagine outside factors could also cause a delay.
Jeff Foust reported in this article that SpaceX has completed 8 milestones so far.Looks like we only have 6 completed on the list in the first post. I wonder what other 2 have been completed?
There is only one constant in manned spaceflight: delay, delay, delay.
If you look at things historically the risk to schedule increase the closer you get to the end date. This is because the builtin cushions have less capability to absorb unforeseen events affecting task completions.

Yeah, right. Just like FH.
Quote from: Jim on 05/15/2016 06:53 pmYeah, right. Just like FH.I have been wondering whether SpaceX deliberately held back FH development while they were working out the kinks in F9 and especially F9 reuse. It would make sense to me to do that, since FH is largely based on F9.Also, it seems like the payload increases in F9 have made FH less urgently needed compared to F9 1.0.
I think similar processes occur within large companies even without government intervention...
Quote from: Jim on 05/15/2016 06:53 pmYeah, right. Just like FH.No. More like returning a first stage and landing it flying backwards-something virtually everyone said was not possible.
1. No. More like returning a first stage and landing it flying backwards-something virtually everyone said was not possible. And doing it in a matter of months, then doing it in the middle of the ocean on a tiny barge, then doing it with a brief three-engine burst and slam landing perfectly in the middle of a bullseye.2. sipin Something old space not only isn't capable of,snip

Quote from: Jim on 05/16/2016 03:26 pm1. Wrong. Dragon is separate from Falcon. There are separate teams.Which is why Dragon isn't "just like Falcon Heavy". The Falcon team has more pressing matters at hand than flying Heavy.

But....If I create a schedule for a project and align everything to all the critical path items and don't leave room for any slippage of those critical path items then, in rocketry or software development or anything else, the schedule is unrealistically optimistic. But if I create a schedule, pad all the critical path items with a realistic buffer, and work to that schedule, then there will be many times that I use the buffer but didn't really need to, or I let non critical path items languish since the schedule didn't make them critical for far longer than they would have been.Another way to express Musk's schedule management style is: "Plan for excellence, when we slip we slip and we own it, but we don't plan for slipping." It actually comes down to whether you are playing the duffers game or the winners game.
C. Validation Propulsion Module Testing (Incomplete)
Not sure what the different colors in the future milestones are supposed to denote. Lavender seems to be the default color, but there are also white and light blue lines of text.
According to Benjamin Reed, director of SpaceX’s commercial crew program, SpaceX is 'on track' to launch astronauts in 2017. Crew access arm and other crew related systems to be installed at LC-39A this summer.http://spaceflightnow.com/2016/05/25/spacex-on-track-to-launch-astronauts-in-late-2017/
Reed said SpaceX hopes to certify the Crew Dragon’s propulsive landing capability, which will allow for helicopter-like touchdowns on a landing pad, some time after spacecraft begins flying astronauts. “That’s certainly the plan, and we’ll work closely with NASA to decide the right time to introduce propulsive landing,” Reed said. [...] “We’re still working (on propulsive landing) right now, but the first thing is to make sure were certified to get the crew up and bring them back safely,” he said.
A very similar slide was shown at the Space Tech Expo this week by Garrett Reisman, Director of Space Operations.
Are the space suits an internal SpaceX goal or required by contract?I had assumed that NASA would want to use their own suits.
Yeah -- hasn't Boeing selected a variant of the Shuttle launch/entry suit for Starliner? Sure to be easily approved by NASA, I would think.I know, from several interviews, that Elon is personally involved in the suit design process. I think he sees the suit design as something that will be a big part of the SpaceX crewed spaceflight "brand," and wants it to represent his vision.It will be quite interesting to see what SpaceX actually comes up with for final suit design. I guarantee you that, if Musk has any say in the matter (and he does), it will not feature that "carrying a load in my diaper" look that the Russian Sokol launch/entry suits have. Musk has spoken repeatedly and specifically to that point...
Yeah -- hasn't Boeing selected a variant of the Shuttle launch/entry suit for Starliner? Sure to be easily approved by NASA, I would think. <snip>
I can explain the mystery of the colors. The light colored (possibly white?) are NASA required milestones - the dCDR2, FTCR, ORR, and CR. The lavender are SpaceX milestones. The light blue are flight tests.
There is CCiCap-CCtCap mix-and-match in that presentation, and a couple new milestones not previously seen...CCiCap milestones; should not be listed as CCtCap:- Pad Abort Test (complete May-2015)- In-Flight Abort Test (milestone date?)New CCtCap milestones since last report:- Post Certification Mission 1 Information Review (complete Dec-2015)- Delta Critical Design Review 2 (dCDR2) (milestone date?)I have not included dCDR2 in the chart as I don't have any dates for it.
Nice chart. SpaceX's Critical Design Review that you have listed as added, is actually left over from CCiCap. That was the milestone that they had split into like 5 different pieces (13-A,B,C,...). They had one last part outstanding and finally finished it. That's why it doesn't show up in the original CCtCap list. It isn't a new milestone, but an old one.
Joek,I think that you are right. Delta CDR in this context is a CCtCap milestone. A CCiCap milestone (13-e) with a similar name was completed on December 15, 2015. But it has a slightly different name. It's called "Delta Crew Vehicle Critical Design Review" (not Delta CDR). See pages 5 and 6 of this NAC Presentation:http://www.nasa.gov/sites/default/files/files/4-CCP-Status-McAlister.pdf
McAlister: expect to formally award 2nd post-certification comm’l crew mission to SpaceX “real soon” (1st awarded last Nov; Boeing has 2)
McAlister: surprised SpaceX decided to develop their own spacesuits in-house, but they’ve done a real good job, on 3rd or 4th prototype now.
McAlister: the crewed test flights Boeing and SpaceX will fly will dock to the ISS for an unspecified period, likely “some number of weeks”.
McAlister: when SpaceX completed delta CDR 2 in Aug or early Sept, will be “turning the corner” in locking down design.
McAlister: we’re getting more comfortable with SpaceX’s use of densified propellants on F9, but not there yet.

Any insight on whether this can be done with the uncrewed test flight? I.e., will it involve cargo return which would preclude testing? And would the large volume of hydrazine be permitted at ISS?
The "several tests" are likely to include (possibly consist mainly of) powered splashdowns at sea, similar to how the F9 first stage experimental landings started, perhaps parachute-assisted as well.Of course there's still some risk of something going awry resulting in the capsule taking a bigger hit than the usual parachute splashdown, but would that be low enough for NASA to accept with their cargo (or even astronauts) on board?
Why splashdown at sea and deal with salt water? Why not splashdown in an artificial lake or even in a pool?
Yes, but landing on a firm land will probably require some sort of legs, which we haven't seen yet. >

NASA *could* insist the majority of it is burned off before approaching the ISS, as a 'third stage'.doing so would of course mean that Dragon would have to do a parachute landing, which is going to be the case for the first few flights anyway.

But there's no reason to expect they *would* do such a thing. Why do you expect them to suddenly panic at the thought of hydrazine?
I didn't say I expected them to do that. I was just pointing out the fallacy of Comga's argument that NASA 'HAS TO' accept it. no they don't.
Musk could have been thinking about high altitude drops from a helicopter. The intent being to test the propulsive landing rather than the TPS system. Much more cost effective than a launch. Still, Mars' thinner atmosphere can't realistically be replicated on Earth.
(As for parachutes, of course they will use parachutes at first for crew return, but I was talking about the uncrewed test.)
Quote from: enzo on 07/27/2016 11:48 pm(As for parachutes, of course they will use parachutes at first for crew return, but I was talking about the uncrewed test.)Understood, however: if that 'uncrewed test' is part of the Commercial Crew program then it's more than likely that NASA will demand a non-propulsive water landing. This is how the first crews will land... test like you fly.
With regard to the large-ish amount of hydrazine on board the Dragon 2 capsule being permitted at the ISS....What about the equally large or larger amount of hydrazine in the Shuttles' OMS pods and RCS system?Hasn't that presumably large quantity of hydrazine already been at the ISS on every Shuttle mission?
[quote author=AS-503 link=topic=39832.msg1564072#msg1564072 Correct that quantities of hyperbolics should not be an issue. Boeing also as a similar issue, and has also mumbled about CST-100's potential ability to help with ISS reboost--although they seem to have gone mum on that subject.
There has always been a lot of hyperbole around the Shuttle.
Seriously, any of these vehicles may be capable of ISS re-boost. Question is how much is it worth vs. just continuing with the status quo? Likely answer: not much.
(snip)I do wonder about reboost. It has been said that the ports are in the wrong position. But the Shuttle did reboosts, right? The Shuttle docking port is one of the ports for CC vehicles so why not? Is it about reorientation of the ISS?

By the way, what the heck is "Gz Studies"?
One note I hadn't realized, and maybe just because I haven't paid enough attention?"Common First Stage w/Falcon Heavy Design"They chose the beefier FH S1 design to add margin for Crew Rating?
Does this get them closer to qualifying the FH as well as F9 for crew?

Would it make sense to use the core for leo becuase dragon would presumably use FH for beo? I would assume NASA would not care since they are not ordering BEO missions, but spacex may be interested in a single qualification path so they can sell higher energy manned missions to whomever.

Under the revised schedule, a pad abort test of the CST-100, previously scheduled for October 2017, is now planned for January 2018. An uncrewed CST-100 flight, called the Orbital Flight Test, has shifted from December 2017 to June 2018.A crewed flight test of the CST-100 to the International Space Station, carrying a NASA astronaut and Boeing test pilot, has been delayed from February to August 2018. If that schedule holds, Being anticipates flying its first operational, or “post-certification,” CST-100 mission to the ISS in December 2018.
Wonder to what extent SpaceX might be helped or hindered by the current down time. Any thoughts?
2. IIRC the in-filght abort test was scheduled to use SLC-39A sometime during the last month or two of this year. SpaceX now seems to be targeting RTF for December of this year and has said they would resume by using SLC-39A. Once RTF happens it would seem there will be much pressure on SpaceX to catch back up on its launch manifest which might make test time on SLC-39A hard to come by.
1. Last year when SX had down time waiting for RTF it seemed they used that time well. At RTF their first launch was their first Falcon v1.1 full thrust with subcooled oxygen and cooled RP-1 among many other enhancements. Interestingly, that first flight was also their first successful recovery of a first stage on land. Could this all have been coincidence or were they somehow able to refocus resources?

A few SpaceX notes from listening to the presentation by Kathy Lueders at the NAC HEO Committee meeting yesterday (you can find the recordings here). The first round of structural tests on Crew Dragon are done, continuing with further testing.They should do the space suit qualification next quarter.They have their 5th parachute test scheduled for this coming Saturday.The crew access arm is at LC-39A, they are waiting until Spring to install it so SpaceX can get the pad up and running for their other launches.They have been doing unit testing on the ECLSS systems and are getting ready for integrated testing.
Some updates: 10 Flight to ISS Without Crew: now November 201716 Flight to ISS with Crew: now May 20188 Flight Test without Crew Certification Review (FTCR): was 3 months before uncrewed flight, so likely Aug 201714 Design Certification Review (DCR): was 1 month after unscrewed flight, so likely Dec 201715 Flight Test Readiness Review (FTRR): was 1 month before crewed flight, so likely April 201817 Operations Readiness Review (ORR): was 3 months after crewed flight, so likely Aug 201818 Certification Review (CR): was 3 months after ORR, so likely November 20189 ECLSS Integrated Test Complete: probably Q1 2017 (see below)11 Parachute Qualification Complete: may be on track for this month, but likely Q1 2017 (see below)12 Space Suit Qualification Testing Complete: probably Q1 2017 (see below)13 Launch Site Operational Readiness Review for Crew: probably Q2 2017 (see below)Quote from: gongora on 11/16/2016 12:18 amA few SpaceX notes from listening to the presentation by Kathy Lueders at the NAC HEO Committee meeting yesterday (you can find the recordings here).

So where will the in-flight abort test be?
Quote from: DOCinCT on 01/06/2017 03:34 pmSo where will the in-flight abort test be?It is after the uncrewed flight and before the crewed flight. So, probably something like February 2018. It isn't on this list because it isn't technically a CCtCAP milestone. SpaceX proposed the the pad abort and inflight abort tests under the previous development contract leading up to the CCtCAP.

10 Flight to ISS Without Crew: now November 2017<snip>11 Parachute Qualification Complete: may be on track for this month, but likely Q1 2017 (see below)
The parachute test is just one of an evaluation regimen that is expected to include many additional parachute drops of increasing complexity. (emphasis added)
https://www.nasa.gov/feature/eclss-put-to-the-test-for-commercial-crew-missions I wonder if this is a signal that the "ECLSS Integrated Test Complete" milestone is finished or getting close.

Would this be at all related to the construction work on the incomplete flame trench area over at McGregor?

Quote from: Coastal Ron on 01/19/2018 05:41 pmOK, so NASA is willing to pay SpaceX to investigate an Inconel version of the current Falcon 9 Composite Overwrapped Pressure Vessel (COPV)?Maybe. I would not jump to the conclusion that this is related to the COPV's used for S1 and S2 as the language is ambiguous; might only apply to the tanks for Dragon and trunk.

Is there a direct link somewhere so I can avoid stressing the server?
Then why also pay to develop and build a Solid Oxygen (SOx) test stand? Sure sounds like it's for the COPV issue.
Quote from: Coastal Ron on 01/19/2018 10:27 pmThen why also pay to develop and build a Solid Oxygen (SOx) test stand? Sure sounds like it's for the COPV issue.Not sure. Because SOx is potentially a much higher risk with current COPV design if used in Dragon vs. S1 or S2?In any case, NASA's own studies indicate AL COPV's are as good or better than Inconel COPV's at cryo temps. (AL requires more over-wrap but in the end performs better with lower mass than Inconel). Although NASA may be revisiting their conclusions given the potential presence of SOx, and thus why they are willing to pay SpaceX significant $ to investigate--which could as easily apply to S1, S2 and other applications.
Accepting the unintended consequences of installing a new, heavier design to replace one that has been pressurized and flown dozens of times since the procedure was changed is insanity.Can't wait for the tell-all book that describes this whole process from the inside...

SpaceX is great because they use agile development. They're not afraid to make changes. They don't get stuck being wedded to a method just because that's the way things have worked in the past. -OR- Changing things once they have built up a flight history is insane! Once something works you shouldn't change it anymore.
It's not a dualism. They have found that LiAl tankage work great... indefinite number of flights possible per EM.
Why doesn't NASA change from use of solid boosters because they once killed a crew of seven?
Quote from: AncientU on 01/20/2018 01:35 pmIt's not a dualism. They have found that LiAl tankage work great... indefinite number of flights possible per EM. No, I think it's confirmation bias. When SpaceX makes changes to their system that drops flight heritage it's great vs NASA potentially forcing them to do the same for their missions is insane. And I would make the same point to those who argue that SpaceX is reckless for making such changes but refuse to recognize NASA is potentially forcing it here. Specifically to the issue of swapping COPVs, we don't know what sort of testing results SpaceX/NASA have been seeing. Are failures predictable and ongoing performance well characterized with their current tanks/procedures? Sure, they have been successful so far but is that success reliable? Without knowing what they have been finding, it's hard to criticize NASA (who does know) for pushing for a change if they feel it is warranted. To my mind, any gain from the switch would have to be pretty significant before I felt giving up the flight heritage was worth it. Of course, SpaceX clearly feels differently and they certainly have seen the same results. QuoteWhy doesn't NASA change from use of solid boosters because they once killed a crew of seven?They did. The design of the SRB joints was altered to eliminate the cause of the Challenger disaster.

Changing a known safe, performant design to something less proven, less performant, and possibly more expensive, would be crazy.
AncientU, overly harsh, but I do agree strongly with your statement " This is demonstrated by their incredibly bad management decisions that resulted in loss of crews". Aversion to repeat that mistake has resulted in ASAP's 1:270 LOM. I think this is an attempt to take political decision making out of the loop, and is a good thing.
Confirmation bias works both ways. Those who are status quo adherents cannot see anyone but NASA having knowledge about rocketry and human space flight. I believe the opposite is true. NASA has proven that they cannot build a rocket and that their management structure, 'processes', and pseudo-risk aversion are fundamentally flawed. This is demonstrated by their incredibly bad management decisions that resulted in loss of crews and their inability to get their act together enough to fly anything. They are dictating the rules because they have the checkbook.
Actually, all opinions are welcome.

Or does this milestone refer to the first flight of the man-rated Block 5 version of the Falcon 9? This chart, at least, makes no other reference to Block 5 development.
