I really need to get a proxy ready. YouTube blocks live streaming for Germany. Any non YouTube video source?Thanks.
Can someone cover this. There's a big event for HSF (space policy) that I have to cover.Notes and screenshots would be great.
CRS-3 Landing video!
Not the clearest picture but you can still read the launch manifest.
SpaceX at the Cape is no longer beholden to AF range safety radar.
Seems to have zero interest in vertical hanger, payload processing, so the AF and Jim will take it or leave it. SpaceX at the Cape is no longer beholden to AF range safety radar.

- Avoiding vertical integration was deliberate early decision to avoid high costs, related to MST (amongst others)

I didn't see a Youtube link so
They have to produce cores for the other missions meanwhile ....
Quote from: garidan on 06/05/2014 07:56 amThey have to produce cores for the other missions meanwhile ....I read the statement they are producing the Heavy cores as they are past production bottlenecks now and have no problem delivering cores for all missions, with pad time the limiting factor.

Also, said they'd need to get better at predicting when those customers will be ready.cheers, Martin
Is there anything on the "Would like to participate" comment on the domestic RD-180 production.
Quote from: Nomadd on 06/05/2014 02:04 pm Is there anything on the "Would like to participate" comment on the domestic RD-180 production.the comment was not about domestic RD-180 production. It was about development of a new US hydrocarbon engine.

It was about development of a new US hydrocarbon engine.They would be crazy not to compete for that. It funds their rocket development team and makes SpaceX the goto company for rocket engines for the next 10-20 years.
Outside funding is nice but the question would be do Spacex want to be the goto company for rocket engines?They have an engine. They have cash flow. They already know their engine team is good.
The question then is, what propulsion work does SpaceX have in it's backlog to keep the engine R&D team busy - and that means design and development, not manufacturing obviously.
Let me suggest that the way US government policy and corporate management decisions over decades mean that the government needs Spacex more than Spacex needs a government research contract.

If they did, the other launch companies would be extremely reluctant to buy engines from a competitor and that then defeats the whole purpose. (Besides: If the engine is also used in an EELV class vehicle of their own USAF also lose the advantage of dissimilar redundancy).I think for example ULA or Orbital would even more afraid to be (or be seen to be) at the mercy of Elon than Rogozin, even though their fear would probably be (mostly) unfounded.

More to the point, won't SpaceX engines be designed from now on for non-expendable vehicles? They may well be expended, but the design will include reusability as part of any new design. Not sure that SpaceX engines would be a good fit for Evolved Expendable Launch Vehicles. That being said, any engines funded by such a program would potentially be under "ease of access rules" or an open design (well, an ITAR restricted version) such that US firms could purchase or license to build with reasonable terms.

We really don't design expendable liquid engines (except for those using ablative nozzles). Even in the 1950s, our specs called for 12 starts, since you'd be firing the engine in qual testing and for calibration prior to vehicle integration.The only items of a liquid engine that need attention for long term reusability are generally the hot section (chambers/nozzles) and bearings in the pumps. Creep in the turbine is a minor concern and seal wear on valve may be but only when the engine is cycled hundreds of times.As an example, there is at least one "expendable" RL-10 used in test that went through >350 starts.

If the US governments RFP for a new big engine fits in with Musks schedule to develop a new big engine then they may compete. If not I'd guess they have enough to be getting on with.The question you have to answer is "How does doing this help Elon get to Mars better/faster/cheaper/safer?" If it doesn't why expect Spacex to do it?
And BTW let's not forget that US Senator who's keen to drop FAR25 cost reporting on a project that was originally bid as a Firm Fixed Price contract? Let me suggest that the way US government policy and corporate management decisions over decades mean that the government needs Spacex more than Spacex needs a government research contract.

USG "has been fine" without SpaceX only because they did not know they could haveeventually gotten the same service at half the price ULA was asking
Sorry, but like the use of the term "evolved" of the Atlas V from the original Atlas, or the Delta IV form the original NASA sponsored Delta design, this is pretty much total fantasy. That's like a Porsche being "evolved" from a horse because they both have 4 supports touching the ground.
