Well, if they want to use it... fine by me. But there's a flame duct that still needs some unicorns first.

TEA-TEB ignite on contact. Turn on the taps for RP1+LOX simultaneously and you have flame.

Not quite. Ignition on the launch pad is initiated from the GSE. They don't carry the TEA/B reservoir with them for that.

For S2 & S1 recovery burns, they have a separate reservoir on the booster. S1 can reiginite only 3 engines as only 3 engines have TEA/B reservoirs.

Yep I think that's a more than fair statement. I'm doing my best to try and dispel this "you're special" attitude that's popped up recently.

I'm really surprised there isn't an entry in the FAQ for this. We have failed!

Well, I don't think that's entirely fair. There's a difference between being wrong because the information is incorrect, and because the information has become outdated.

A lot of the times, it's the latter. For example, here's my SpaceX employee-reference for landing legs being removed post-launch. It's completely public and everyone missed it.

Has it changed since then? Maybe. I'll keep repeating it until I hear otherwise though.

It would, but there's no source attached to it apart from a confusing username.

The username "nsfwaterdrip" says it appears to be coming from NSF, which is generally a reliable source of information.

Echo, could you try your luck with Elon on Twitter for clarification? Out of all of us here, you would be most likely to get a response!

The chance is the same regardless of who tweets :)

Interesting comment from this user:

Sources indicate that reflying F9-0024-S1 would require refurbishment costs of similar equivalent value to a new first stage.

https://www.reddit.com/r/spacex/comments/4ku6ax/spacexs_benjamin_reed_falcon_9_booster_on_jcsat/d3i1jel

Maybe Musk was being "technically correct" when he said it could "def. refly"? I mean sure... anything can definitely refly if it had enough refurbishment.

I think in such a complicated subject matter, it's pertinent to expect delays and changes of plan. SpaceX is that agile, that things probably change daily.

This one is addressed to the Bigelow engineers. Can you comment on your working conditions a bit?

Bigelow has gained notoriety recently for having somewhat poor employment conditions, for example, the Bigelow glassdoor page is not exactly positive.

Elon seems like a pragmatic sort of guy. He sets his sights on a goal and fights like hell to achieve it, letting nothing stand in his way. The path he walks to achieve it is well defined at its start and end.

It's not clear in the middle. Twists and turns exist at every step. It's frankly naive if people think what he's proposing can be achieved in one fell swoop. It's one of the reasons why it simply hasn't been done before.

EDIT: So can someone outline why this viewpoint is so controversial? Lots of driveby downvoters. I thought this community was above that.

And I should add: this is not me trying to diss SpaceX or anything. In fact, I'm trying to do the opposite. SpaceX employees work their asses off every day to make all this possible. They've spent tens of thousands at pricey universities becoming masters of their specific domain. They deserve a little credit for what they've built.

[–]EchoLogic 17ポイント18ポイント  (0子コメント)

The expensive contracts are the ones that go to the 4 other orbits. So while a smaller fraction of satellites do, a greater portion of money spent does.

The goal has always been rapid reusability of all components of Falcon. They'll get there eventually; but people who expected it right from landed core #1 are precisely the sort of people that simply don't have a good grasp on the complexities involved here. I include myself in this statement. Aerospace has to have one of the widest gulfs of technical understanding between fans and professionals.

If you're a fan, and you think you understand aerospace engineering: you don't.

Hopefully this will teach the Facebook Fan Club a thing or two.

It's not a mass to orbit problem, it's a capabilities problem. Direct GEO insertion and similar "difficult" orbits require capabilities SpaceX has yet to develop.

Indeed, they may not even bother if the costs to develop are expensive.

Yes, they're duplicate satellites of the previous two.
