Well they have a lot of employees and thus presumably lots to barbecue...

I've found a bunch of pictures on a server, they're being posted to a forum here. No idea where they're coming from though...

the RLV experimental permit is very interesting. i'm sure it's for the 1st stage recovery - the suborbital market is just too small for SpaceX to bother with. The "vehicle" is also a F9 first stage that they're going to try to VTVL...

There has been some interesting commentry on Arocket - that the cost of sticking wings on to get back to launch site vs VTOL to get back are pretty much the same (within a percent or 2). Quite an extensive, but proprietary report apparently.

I'd be interested to see what could be done with a hybrid - stick on small wings (even just slightly bigger fins) to help with lift and combine that with VTOL capability. Maybe what BO was doing with those odd fins on the vehicle they just lost.

The whole VTOL thing for F9 won't work apparently (pinch of salt) - the first stage is going at too high a mach number to recover, but might be OK for F9 heavy where the first stage is dropped earlier on because of the cross feed system.

Elon will speak at the national press club today at 1 pm EST
(dunno if this is 19:00 CEST? edit: yes it actually was :P)

http://press.org/events/npc-luncheon-elon-musk

look at the teaser picture of grasshopper!

looks like those who think that effort is to recover F9 stages and not for the suborbital market were dead on! :)


And check out the video! I just hat a "spacenerdgasm"! :shock: 8)

PS: SpaceX has an awesome taste in music! ;)

^^^^^^^^^ What he sai d ^^^^^^^^^^^^

Not just the first, but full recovery of all stages....being pretty impressive to watch if he pulls that one off.

Muse....awesome.

Has anyone seen if they recorded the press conference or left a transcript?

Thanks Nick;

Anyone out there who is an Elon Musk fan, you should put this on your must watch list.

I still love how he just sounds like some awkward nerdy guy explaining all his crazy schemes like they're obvious to anyone with half a brain.

Of scifi titans of industry, you have to think of Heinlein's guy whats his face "The Man Who Sold The Moon".

Problem is that most people only have half a brain. Or at least, they only use half of it. I refer you to some of the comments on various forums slagging off his ideas, by people who obviously have no idea what they are talking about, but who could have used Google to give themselves even the slightest clue. And didn't.

Well I googled and came up with this:

"You know how dumb the average guy is? Well, by definition, half of them are even dumber than that"

"50% of the citizens of this country have a below average understanding of statistics."

Actually, if you take the common definition of the arithmetic mean for "average", then both those statements are false. Half of the people are dumber than the median guy. But to be fair, correctly applying statistics is difficult, and most people get it wrong pretty often.

A good system architecture is based on a good understanding of the problem and a good decomposition of the solution into orthogonal aspects and independent components. A great system architecture is based on a great understanding of the problem and the world it is a part of. It anticipates the future and doesn't just solve the problem, it changes the world surrounding the system for the better.

Elon Musk is a very good systems architect, and the Falcon/Dragon programme is a fantastic solution to the problem of space launch, not just the technology aspects of it, but also the commercial and operational aspects. Those people disagreeing are just jealous of him being rich, smart and having a gorgeous wife :-).

SpaceX Completes Key Milestone to Fly Astronauts to International Space Station

HAWTHORNE, Calif., Oct 20, 2011 (BUSINESS WIRE) -- Today, Space Exploration Technologies (SpaceX) announced it has successfully completed the preliminary design review of its revolutionary launch abort system, a system designed for manned missions using its Dragon spacecraft. This represents a major step toward creating an American-made successor to the Space Shuttle.

NASA's approval of the latest design review marks the fourth successfully completed milestone under the agency's Commercial Crew Development (CCDev) program and demonstrates the innovation that's possible when NASA partners with the private sector.

"Each milestone we complete brings the United States one step closer to once again having domestic human spaceflight capability," said former astronaut Garrett Reisman, one of the two program leads of SpaceX's DragonRider, which is adding capabilities to the Dragon spacecraft for astronaut carriage.

Now that the Space Shuttle program has ended, the United States relies on the Russian Soyuz spacecraft for astronaut transport, costing American taxpayers as much as $62 million a seat. By comparison, Dragon is designed to carry seven astronauts at a time for an unparalleled $20 million per seat.

As with all SpaceX designs, increased safety and reliability are paramount. "Dragon's integrated launch abort system provides astronauts with the ability to safely escape from the beginning of the launch until the rocket reaches orbit," explained David Giger, co-lead of the DragonRider program. "This level of protection is unprecedented in manned spaceflight history."

With the latest design review approved by NASA, SpaceX can now start building the hardware at the heart of its innovative launch abort system. The SpaceX design incorporates the escape engines into the side walls of Dragon, eliminating a failure mode of more traditional rocket escape towers, which must be successfully jettisoned during every launch. The integrated abort system also returns with the spacecraft, allowing for easy reuse and radical reductions in the cost of space transport. Over time, the same escape thrusters will also provide Dragon with the ability to land with pinpoint accuracy on Earth or another planet.

In its first flights, on June 4 and December 8, 2010, SpaceX's Falcon 9 launch vehicle achieved consecutive mission successes. The December mission, which was the first demonstration flight under NASA's Commercial Orbital Transportation Services (COTS) program, marked Dragon's historic debut and established SpaceX as the first private company to launch and recover a spacecraft from orbit. As a result, many Falcon 9 and Dragon components required for transporting humans to Earth orbit have already been demonstrated in flight.
