I think the micro-sats are a lot more interesting.  I mean...using COTS stuff to build them?  Farking RAD!!!!

For starters you can throttle them and turn them off if something goes wrong.

Fluctuations in chamber pressure and asymmetrical trust from the stack is a pretty good tip-off - and something the Saturn V guidance system would account for and handle automatically (ref early centre engine shut-down on the second stage during the Apollo 13 launch).

There were two major issues with the Shuttle system that caused the Challenger disaster; lack of a LES and mounting the payload on the side of the stack. Using solid fuel engines (which cannot be throttled or shut down) just made it worse. Off course the REAL reason is that NASA deceided to launch even if the guys who built the damn solid fuelled boosters asked them not to...

If they get it up, that'll be two private companies that can get things into orbit. Meanwhile, Branson is still playing with suborbital shots.

Also Luna 2, which reached the moon in 1959 (and crashed). Luna 3 returned the first pictures of the far side in that same year, and Luna 9 in 1966 was the first spacecraft to soft-land on another celestial body.

Beyond the moon, they also launched the first probes to Venus in 1961 and Mars in 1962 (although these ones failed on the way).

Well, different somewhat. Virgin Galactic is going to be manrated and all reusable. Space X has a good plan by using the resupply lifts for data and tests (and being paid for it) which will lead to manrating the Dragon.

To boldly go where we've gone before, the same way as before, but with cheaper parts. Anyone order a case of Tang and freeze-dried ice cream?

There's glorious exploration to be done, at 0.08 Earth radii up, in a tin can we built.

My God, maybe we'll even know how water squeezes out of a towel?

I am on tenterhooks.

Considering I just made and launched a 12 SRB first stage, 3 SRB second stage, 1 liquid fuelled descent stage rocket that made it up into orbit, then soft landed after 1 full orbit on that game, I'd have to say....Not Obscure.

Nah, not obscure at all! I've landed on Mün plenty of times, I've even manged to get a few Kerbals back to Kerbin alive, and I stress the "few" part....

Liquid systems are inert until they are loaded with prop on the pad. Solids are basically well behaved bombs and you have to treat them with kindness and paranoid love up until you ignite them.

Pyrotechnical systems and other systems have to be operated differently on the pad and during processing for solids than liquids to not cause the solids to ignite by accident. Comm checks and other RF operations are also restricted near solids that are not an issue with liquids. The advantage of solids is that they are often cheaper to build and they are storable, so you can put them in a launch tube on a sub and forget about them until you need them.

I'm stoked that we are finally burning big holes in the sky from VA.

It's sad when Space Nutters themselves can't be arsed to do 30 seconds worth of typing about space. The Soviets sent probes to Venus and Mars too. Did you know Venus and Mars are further away than the Moon?

meanmutton: Honestly, there's something really sci-fi about having private companies like SpaceX and Orbital Sciences launch cargo into space.


Um, who do you think built rockets before? Let me clue you in, private companies like Boeing and Lockheed, for starters...

So if by sci-fi you mean business as usual for the last four or five decades, then yes.

Space gurus, is that 16,000-launch number accurate? That'd be 239 per year, which sounds high to me. KSC/Canaveral is on the order of one or two a month, maybe.

Solids are reasonably easy to make and powerful, but not very efficient and very limited in how they can be controlled (no "off" button). If anything goes wrong with a solid, it's going to go very wrong. Even a loss of vector control could wind up being a more serious problem. There are solid fuel hybrids that address some problems by using a liquid oxidizer.

The Antares uses a liquid fuel first stage and a solid fuel second stage which is probably the opposite of what you'd want if money were no issue. As it is, the first stage is using much of its thrust lifting a heavy inefficient second stage out of the atmosphere. Ultimately all that matters is $ per pound to orbit.

Wallops mostly has launched sounding rockets that are basically big ass Estes rockets. So the high number is not quite the same as if they'd launched a bunch of Atlas or Delta rockets.

This is a typical rocket launched from Wallops prior to Antares:

Orbital has been launching to orbit for awhile (since 1990) now using their air-dropped Pegasus rockets. This is just their largest rocket and ground instead of air-launched. Also, this one is being built and launched on a COTS basis, and not Cost+.

Boeing and Lockheed will happily sell you a commercial launch today through their United Launch Alliance subsidiary on either a Delta IV or Atlas V. The Antares and Falcon rockets are different not because they're commercial, but because of the pricing structure.

I was concerned after the previous test, when the hose came loose prematurely.
"Can't those Kerbals get anything right?!"

Gaseous Fluorine is hypergolic with just about anything.


"[Chlorine Trifluoride] is, of course, extremely toxic, but that's the least of the problem. It is hypergolic with every known fuel, and so rapidly hypergolic that no ignition delay has ever been measured. It is also hypergolic with such things as cloth, wood, and test engineers, not to mention asbestos, sand, and water - with which it reacts explosively." (emphasis mine)

This story is weak compared to the usual nuttery. A firecracker went up and will carry peanut butter and Tang a whole 400kM. A defense contractor no less. But it's allll private! Huzzah! Huzzah for the "free" market (heavily subsidized by the government)!

awesome. hopefully their next test goes just as well. for anyone that doubts that this is significant, we currently have a gaping hole in our ability to transport supplies to the ISS, which is no trivial task. we all want to see that gap filled so we can continue our presence in space as a nation and now we have a greater chance of meeting the goal of having two vehicles capable of the feat. Yes, other launch vehicles exist, but whether we're inventing new ones or re-purposing old ones rendezvousing with the ISS is a specific task the requires specific hardware, software, and substantial investment to achieve. to trivialize this is to underscore ones own ignorance
