Update here:

now says nominal 2nd stage burn and sep complete. Not sure who it is, though.

Is the satellite alive?

This is way too tinpot for my liking. I'd want to see official confirmation.

I'm with you Chris... I hate.."but I read it on twitter"...
but I'm still hoping its true.

edit..pics look like a party at Hawthorn? (sp?) so maybe Elon gave them the good news

Chris Bergin · « **Reply #723 on:** 07/14/2009 04:46 am »

Ok, it's confirmed (a top NASA guy who deals with them confirmed it to me, and he's one of my sources, so it's as confirmed as it gets bar a press release

Congrats SpaceX!

And thanks for everyone's patience with the coverage on this thread. It was getting a bit out of control, so there was some housekeeping required, but everyone got with the program when we most needed it, so you all have my thanks, especially those that contributed to the coverage.

Surprised there isn't an "official" news release yet.. probably just crossing the "t"s and dotting the "i"s...

EDIT: just saw Chris' post... that's good enough for me!!!

jabe · « **Reply #725 on:** 07/14/2009 04:47 am »

WELL DONE..
Now to bed and have my kids wake me in 5 hours lol

edit:Can't wait to read what Spacex has to say about it...

and lets hope some HD clips are out on the web somewhere so I have some morning Videos to watch with my son...

Agreed. Congratulations SpaceX!

F1 finally put a paying payload into orbit.

Lets hope the payload is alive and healthy.

Are correct orbital parameters implied by the SpaceX announcement?

Antares · « **Reply #729 on:** 07/14/2009 04:51 am »

Chris, does that include healthy spacecraft?

ugordan · « **Reply #730 on:** 07/14/2009 04:53 am »

Spaceflightnow also has confirmation by a "SpaceX spokesperson".

Congratulations to all involved on what looked like a near-flawless launch. With little fanfare on this (almost to the point of looking like they're hiding something) and mostly in the shadow of STS-127 launch campain, they finally got this one done.

If I were to comment on the lack of any public and press info, I'd say it might have had something to do with certain accusations that tended to float around about them being all-hype and that they should "put their money where their mouth is". Hopefully, this success is just the beginning of a long succesful streak.

No doubt a confidence builder for the F9 campain.

No. Just a good second burn and good s/c sep, that's all I got.

Congrats to SpaceX! Another great omen for their future.

here is a youtube clip

not sure quality or how to just post the link

Do the shuttle engines glow red like that on the way up. Or do they have a better cooling system? I know this is a one time use and throw away engine.

ApolloLee · « **Reply #735 on:** 07/14/2009 05:02 am »

As they would say in sports.... Space X is on the board! Many congrats.

The future is just beginning.

Shuttle engines HAVE a cooling system. This one, like the RL10 and AJ10 for instance, has NO cooling system. It just gets hot and radiates.

This engine is radiatively cooled and the glow is normal for that kind of design.

I just checked the leading Malaysian newspapers and theres no news there yet.

There are three main types of cooling systems, regenerative (fuel passed through tubes making up chamber and nozzle walls to absorb heat, resulting in a low temperature nozzle), ablative (heat is absorbed by sacrificial material in the chamber/nozzle melting/vaporizing away), and radiative (heat is radiated from a glowing hot nozzle). The SpaceX kestrel has a radiatively cooled nozzle, which is why it glows. It basically heats up until the rate of heat loss to radiation is equal to the rate of heat addition from the combustion products. The shuttle main engines (as well as the SpaceX Merlin C and later versions which power the first stage of Falcon use regenerative cooling and so stay at low temperature and do not glow. The choice of radiatively cooled nozzle is not so much because it is throw away but because more complex systems are not not needed on the upper stage engines, so eliminating them reduces weight, increases performance, and lowers chance of malfunction.
