- Experience of key staff?- Financial security?- Funding source/contract type?- Success rate of similar projects (recent, or otherwise)?- Flight history of technologies involved?- Governmental support?- Other factors?
- Engineering culture of the organization.Why did the first flights of Falcon 1 fail?
Given it a descriptive thread title and moved to SpaceX. Not a fan of generalizations of the community.
- Funding source/contract type?...snip...- Other factors?
I've noted that the most widely-shared sentiment expressed about "NewSpace" companies on this site, and most vociferously about SpaceX, is "I'll believe it when I see it".Now contrast this with the prevalent attitude here towards established firms' (and NASA's) non-STS human spaceflight/launcher plans, which seems to include the tacit assumption that if started, they will succeed (i.e. "I'll believe it when it's announced").
I have exactly the opposite impression, Peter.
To reiterate: I'm interested in what factors feed in to feelings of scepticism (or otherwise) of whether a project is going to succeed or not.
Efficient use of labour and capital dispells skeptics.

Federal Express in its first 15 years is a great example.
I've noted that the most widely-shared sentiment expressed about "NewSpace" companies on this site, and most vociferously about SpaceX, is "I'll believe it when I see it".Now, this is often a perfectly justifiable attitude. Certainly, when a new player appears in an established market, using an unfamiliar business model and making preposterous claims about prices and schedules, anyone sensible should treat them with a healthy dose of scepticism.Now contrast this with the prevalent attitude here towards established firms' (and NASA's) non-STS human spaceflight/launcher plans, which seems to include the tacit assumption that if started, they will succeed (i.e. "I'll believe it when it's announced"). For example, it seems to be a foregone conclusion that CST-100 will fly with passengers, even though it's not flown at all yet.I think I'm missing some contextual information or something, because I don't understand why some projects seem to deserve much more scepticism than others. For example, I personally (perhaps naively) consider, from the status quo at the time of writing this post:- manned Dragon more probable to succeed than manned CST-100, on the basis that a Dragon test article has already flown on the intended launch vehicle and reentered safely, whereas CST-100 has not;
- Falcon Heavy more probable to fly successfully before 2017 than SLS, on the basis that SpaceX has a track record of successful & timely de novo launcher development in the near past, whereas NASA doesn't.
Now, I'm not arguing that I'm right about this, and I don't want this thread to devolve into a debate about whether the USA needs SLS or not, etc. What I'm interested in is what objective factors people feel weigh into their assessments of how likely a given launcher or spacecraft development project is to succeed, because I guess they're different from mine.- Experience of key staff?- Financial security?- Funding source/contract type?- Success rate of similar projects (recent, or otherwise)?- Flight history of technologies involved?- Governmental support?- Other factors?Please illustrate with examples, because I'm really interested to see why people adopt an "I'll believe it when I see it" stance towards some projects but not towards others.Hopefully this'll be an interesting discussion. (P.S. I'm a long-time lurker, but have just recently created an account. Sorry to mods if this thread is created in the wrong section.)
Chris: I meant this thread to apply to all of the "NewSpace" companies, not just SpaceX (so Blue Origin, SpaceDev etc). I should have guessed that using SpaceX as the illustrative example would make people focus on it to the exclusion of all else. I also agree that "skepticism is justified for all announcements", but perhaps there is some room for debate as to degree. ;-)
