SpaceX Successfully Tested Draco Thruster
dj writes "The propulsion division of SpaceX has performed another important test. After the test of the Falcon 9's first stage Merlin engines, the smallest engine of the SpaceX family, Draco, has been put to test. During the test, the thruster fired for ten minutes, paused for ten minutes, and then was restarted for an additional minute.
The test was performed on a new vacuum test stand built by SpaceX, and put into operation in March 2008 at the SpaceX Test Facility outside McGregor, Texas."
That'd be a Nimbus 2001.
Squirrel!
to see some good news coming out of the space sector.
Given the current roller coaster that is diplomatic relations with Russia do you really want to be reliant on Soyuz? Also the ESA capsule although successfully tested for cargo is still vaporware as far as manned spaceflight is concerned as I believe they haven't decided if they are going to go down that road yet. With the shuttle being retired the Dragon Capsule looks like a good stopgap.

Really? How many telescopes does SpaceX have in orbit? How many active probes does SpaceX have orbiting other planet, or on them for that matter? How many satellites has SpaceX put into orbit this year? SpaceX is doing some amazing stuff, but to pretend that they are ahead of NASA is just plain daft.
Just because you are paranoid does not mean that no-one is out to get you.
So, then..... why are they working on this? As I understand it, their launch system is already lucrative enough as it is. Why go reinventing the wheel?
First, neither Soyuz or ATV are a US solution. Second, neither are a commercial sector solution.
Choice is always good. Aside from that, SpaceX' stuff is all entirely privately funded and designed themselves, and as such doesn't have the same kind of legal snarls that using governmental technology would have: it is, if you like, a clean room reimplementation of space technology. (They are the only space company to build their launch vehicles, in their own factory, from scratch --- engines, tankage, the lot.)
Also, the Dragon is likely to be (a) cheaper and (b) here on time, when compared to the ESA or Ares capsule (assuming the Ares capsule's not going to be cancelled). And Soyuz, despite being really nice technology, is politically a bit uncomfortable, so it's always worth having a backup.

You're missing the point (which, for the record was mindlessly obvious). SpaceX, in their area of specialisation (ie propulsion/cargo delivery) are showing a whole lot more progress than NASA. All too easy to purposely misinterpret to get on your soapbox.

Goes into significant detail of why SpaceX is really revolutionizing the launch business.
How we know is more important than what we know.

Almost all of the Mercury programme occurred during NASA's first five years. The problem with NASA now is not that they are a "defunct agency", but that they are badly underfunded for the mandate that they have been given. Admittedly, the VSE is highly unrealistic, but if that is the path that the US wants to follow then the US needs to be prepared to fund it. Expecting NASA to push the boundaries of manned space flight and then not being willing to put up the funds to do so is a recipe for failure.

The question isn't whether or not SpaceX progressed more rapidly than NASA did over 40 years ago (with a real federal budget). The question is whether or not SpaceX is ahead of NASA right now. NASA hasn't truly developed a new propulsion device to get the Shuttle into orbit, nor have they designed a replacement for the Shuttle. A craft, may I remind you, that has been having technical difficulties of late and caused more deaths than the original lunar capsule.
SpaceX really is our only hope to continue manned space flight in the foreseeable future ('our' meaning the US). They are definitely ahead of NASA who hasn't even gone past the theory stage as far as we know, and even that seems optimistic.
Oh and remember, the Ares I is a expendable lifter like the Falcon 9. You can't compare it to the Draco as its not intended for manned use. NASA just flat out can't compete currently with this kind of thruster development, and they are going to have to rely on it unless Russia (who seems to have some animosity for America still and the Cold War is still fresh in both nation's eyes) gets buddy-buddy with us since the Shuttle is being retired!
I don't think NASA of 2008 is ahead of where NASA was in 1963. Sad.

Space X was founded in june of 2002. Just six years later, starting from a clean sheet of paper and producing most all of the rocket themselves; structures, engines, avionics, falcon 1 successfully reached orbit. The falcon 9 is being prepared to fly next year, as is the dragon seven crew/cargo spacecraft. Could NASA or any of it's contractors do the same in as short a time? Look how long the Orion spacecraft is taking. Can't beat their prices either, at around 7 million, a ride on a falcon 1 is an excellent bargain! Don't deny their props, Space X is accomplishing astounding feats for such a young company.
Well, to be fair to NASA, SpaceX doesn't have to deal with a gargantuan bureaucracy, Congress, and the President in order to get approval to do anything or even get money and then wait for contractors to build something. Also, it should be noted that some of the people of SpaceX come from the very contractors that NASA relies upon, and so have the hands on experience and contacts to make it work.
It's really kind of a DUH conclusion. A small lightweight unencumbered company can out-perform a gigantic bureaucratic behemoth.
Gee, go figure!

"SpaceX Successfully Tested Disco Thruster"?

Fascism starts when the efficiency of the government becomes more important than the rights of the people.
To compare SpaceX and NASA is silly. NASA does not built rockets. Boing and McDonald Douglas built rockets. NASA buys those rockets from contractors. What SpaceX is hoping to do is become a contractor and sell rockets to NASA.
This is not unique to NASA. The US Air Force does not build airplanes either and the Army does not build rifles.
NASA was founded in July 1958. John Glenn orbited the Earth in February 1962. Neil Armstrong walked on the Moon in July 1969.
