Here is an update:
http://www.foxnews.com/scitech/2011/06/03/danish-teams-homemade-space-capsule-blasts-off/
Multiple U.S. sources are reporting that it went "two miles" or "three kilometers" high, with a total flight time of about 21 seconds. Danish sources, however, say 15-16 km. I think the U.S. sources are confused: 2 km and 21 seconds was when the rocket shut down its engine. Then it continued to coast far beyond that.
An possible explanation can be that the POWERED flight took it upto
3 kilometers before the rocket burn ended, with 1/3rd of the atmosphere below it, and a terminal velocity somewhere between Mach 1 & 2.
Then it simply coasted upto 15-16 Km, with drag and gravity keeping it
from going higher.
15-16 Km is certainly not outer space, and not quite the boundary region below space, but commendably the rocket flew higher than commercial jets fly.

Correct, and that is about the altitude this rocket was aiming for; it is quite a bit smaller than their eventual manned flight. I guess we'll have to wait a bit untill we get more info from copenhagen suborbitals to be sure to what height they got.
Anyway, I loved watching this, despite low quality. When it launched and the control room bursts into screaming, I was muttering "yes! yes!" under my breath aswell

To clear up any confusion:
1st, there was a submarine involved last year, but not this year.
2nd, the target was 15 km, but it reached 3 km, because a flight control system hasn't been implemented yet - it went off course and automatically aborted. This is also the reason why parachute deployment failed - the speed was too high at the time.

Thank you for the reply!
I wonder, what are the plans for Copenhagen Suborbitals now? Another one of these, with a guidance system?
On the site I saw some experimentation with dual-liquid fueled rockets aswell. Hopefully they have gotten good data / experience from this launch.

Pretty good for a first launch. Anyone who gets their rocket flying is doing a pretty good job.

I don't think it's a first launch.

First launch second attempt at launch.
On the first attempt a LOX valve froze and it didn't leave the pad.
Considering they flew without the flight control system I say it went pretty good.

Good work!
Any word on condition of the recovered rocket?
Btw I assume it is reusable. Is this correct? I couldn't find any statement regarding reusability on their website.

http://www.youtube.com/watch?v=91Qm1GdBQE8&feature=youtu.be"Copenhagen Suborbitals:
First flight of the HEAT1X-Tycho Brahe ended with a splashdown of the Tycho spaceship after 86 seconds, 8 kilometers downrange from launch site.
The video depicts the pilot (dummy) POV throughout the flight. The parachutes did not deploy fully, so the impact was rough enough to dislodge the observation cupola upon splashdown. The spacecraft was otherwise mostly intact with only minor deformation and water damage.

That's some thrust oscillation there, even at half speed.

No kidding. I was wondering how much oscillation those "pulses" in the exhaust you could see in the external view were actually inducing. I guess now I can stop. I wonder if they'll be bad enough that they have to put some sort of damping mechanism in.

(perhaps this should be moved back to the suborbital forum )
They have put up a pretty big press pack for this launch now.
http://www.copenhagensuborbitals.com/campaignjune2011_data.phpincludes multiple video angles, pre -during and after launch pictures, and data. Some pretty nice close ups aswell.
Attached a picture from one of their photo albums.
The spcecraft took a hard landing and suffered quite some damage.

Whoa, that's some thrust oscillation! Sounded like a steam locomotive taking off!

Hi everybody
Here is a video with highlights, it nicely edited.
