SpaceX finally makes it to orbit
September 28, 2008 4:52 PM Subscribe
SpaceX's fourth flight was successful. Scaled Composites' X-Prize winning SpaceShipOne made the first privately funded hop into space. SpaceX just took the next big step and inserted a dummy payload into orbit. Next, they will launch the much larger Falcon 9 and later test out the human-carrying Dragon. CEO Elon Musk also enjoys dabbling in banking and exotic electric cars.

I'm reading about about this stuff right now, so it was really weird seeing all these names on the front page. It's also a little disheartening that in the N years since that book was written, they've only made a couple extra flights. We should be on Mars by now!

It would be nice if it could pick up some of the slack after the Shuttle shuts down in 2010.

Rocketeers, which I now realize is actually only 3 months old. In my defense, I'm only up to around 2004.

How did Space-X manage to get viable? Was it the mass infusion of cash?

Well, I guess fourth time's the charm... Here's hoping their later designs don't have this much trouble.

A dummy payload?
"To be on the safe side and not give people arriving on the scene that there was a dead person in the suit there was a placard inside the visor of the helmet with the word 'Dummy' (MAKET in Russian). This precaution had been taken at the direct orders of chief designer Sergei Korolev."

I love how, in my lifetime, technology has moved forward, and changed the world, at a faster pace than ever in history, allowing us to communicate instantly with almost anyone in the world, giving us a chance for the first time to set up stable communities which can all interactwith one another, telecommuting giving us the opportunity to work from home and reubanization the chance to thrive within walking distance of one's domicile, and yet we still can really only see "the future" in terms of how far and how easily we can travel.

Falcon 1 Flight 4 vehicle carries a payload mass simulator of approximately 165 kg (364 lbs)
Sweet: that's me, a spacesuit, a parachute, a small rocket to decelerate out of orbit, and a case of Dogfish 60 Minute IPA.

By 'dummy load', they mean John McCain is suspending his campaign to help with the launch by being the dummy. The McPayload is due to fall back to earth several hours later, landing in a secret location in Pakistan, roughly between Gatesofhellistan and Osama bin Laden's cave, where he will deal with our greatest enemy in hand-to-hand combat, slaughtering him mercilessly with a plastic MRE spork, before returning to a hero's parade and a naughty behind-the-curtains (and out of sight of Cindy) tongue kiss from Sarah Palin.

As someone who rarely ever follows this type of news, I'm almost surprised that it has taken this long for a privately funded space mission since the technology has been around for so long. So when can we expect the consumer models to show up at Wallmart?

re: jamstigator,
Do you honestly believe that McCain could survive a trip into space, much less be able to have enough range of movement in his arms for anything naughty?
Of course, if we're lucky, maybe we could convince him to Maverick himself on a mission to walk on the sun. He's a POW you know, he can handle it.

Succeeding on the fourth try is actually a pretty reasonable performance for a launch vehicle.

Excellent news. I hope it starts being profitable for them soon.
On a side note, does anyone know why they went with an oxygen/kerosene engine instead of oxygen/hydrogen? I couldn't find an answer on their website.
I'd always been under the impression that an oxygen/hydrogen reaction was preferable (more bang for your buck), and that the only reason the US used oxygen/kerosene was because of materials difficulties that have been solved since the development of the Space Shuttle. Apparently I'm mistaken, but does anyone have a link explaining why I'm wrong?

It is, I guess it's more the fact that I've been following SpaceX ever since Musk announced it, and it's been kinda hard watching them get so close and having it fall apart at the end.
In any case, I'm glad they got this one.

I don't know for sure, but there are secondary costs to using hydrogen: Though the specific energy (energy per unit mass) is higher, the density is significantly lower, so you need a bigger fuel tank which cuts into the weight savings somewhat. Plus handling liquid hydrogen at -250 C is significantly harder than either liquid oxygen at -180 C or kerosene at ambient temperature. I bet, in the final analysis, kerosene ends up being cheaper, even if it is less efficient.
(which makes me wonder whether solid fuel wouldn't have been cheaper still)

inserted a dummy payload into orbit [link to definition of escape velocity].
Escape velocity is not relevant to rockets. A rocket could leave the earth's gravity well at a constant 1 mph if so designed.
Escape velocity is effectively about the muzzle speed of guns trying to launch things into orbit. We don't do that much.

Come again CaseyB? In order to get into orbit with a rocket, gun, or plasma accelomator, you need to have a kinetic energy equal to your gravitational potential energy. That means going fast. Like Mach 3 Fast.

Caveat: I'm talking about orbital velocity which is different, but not unrelated to, escape velocity. You could I suppose leave earth orbit by moving at 1mph until the force of gravity from earth reduces to a point where you only need to be going 1mph to escape, but that would:
a) take a ridiculous amount of fuel (far better to reach orbital velocity first), and
b) have no relevancy to the discussion about an orbital vehicle.

No, CaseyB is right - escape velocity applies only to objects without propulsion of their own (it's even in the article you linked).

Re: why they didn't go with solid fuels...solid rockets aren't throttleable, and tend to accelerate much faster than liquid fuels. It's good for the vehicle to throttle back around the time of maximum atmospheric pressure on ascent ("max q") for both the payload and the vehicle itself. Plus, once you turn on a solid rocket, you're going somewhere, cause you sure you ain't turning it off...

They could have used a solid fuel, liquid oxidizer engine to gain throttleability, like SpaceShipOne. Maybe its that liquid fuels allow spacex to test on the pad.
