Launch News North Korea comes again for third attempt to send satellite into space in April

[Cosmic Penguin]

Hmmm......... North Korea is now 0 for 3 attempts to launch a satellite, and 0 for 2 since early 2009. At the same time, the Iranians (using technology they got from the North Koreans) did 3 out of 3 attempts. Wonder where the difference is......

Then again, the Koreans in the south is currently at 0 for 2 since August 2009, and SpaceX was at 0 for 3 in mid-2008......

:shrug:

I wonder if it's all a show, a failed attempt at trying to impress people (the satellite could have been a cardboard box with bits of glass stuck to it for all we know)

So NASA was lying about the Space ocean that the Apollo missions really went to.:lol:

The North Koreans has declared defeat. The launch was at 22:38:55 UTC. http://forum.nasaspaceflight.com/index.php?topic=28357.msg883744#msg883744

Looks like NK's new kid, Kim Jong-un, has already be trained to observe a falling rocket/missile...... :rofl:

Seriously, the rocket apparently failed at around first stage separation, and the remains of it splash down in an area roughly 30 km / 20 miles west of the Korean coast near Seoul.

South Korea claims the failed rocket violated its EEZ (but not its territorial waters).

Something is quite odd with that graphic. Apogee at 150kms while on first stage? :rofl:

Failure at stage separation. Probably contact between stages.
If it occurred at 15km it makes sense, the atmosphere is still very dense.

That's why multistage space launchers are not very good as weapons...

The EEZ stretches 200 nautical miles from your coast, of course the rocket is in that distance, 200 nautical miles from South Korea would be China.

Check the image again--it's NOT 15, they placed 151. :lol:

I wonder who will win the Korean space race? The RoK and the DPRK are both having terrible luck with launches.

Kerbal, hands down! :lol:

But seriously, how far did the US get on their 3'rd launch?

IIRC, their third attempted orbital launch was successful, placing Explorer-1 in an LEO.

 

[Gumok]

I know the reason for North Korea's launch failure - they don't have Orbiter on their computers. :lol:

Note for next time: Use a bigger rubber band. :lol:

I know, and I interpreted it as a typo error. But i've seen similar high altitude values for stage separation on other small rockets. It actually makes sense if you don't want to fly low over your neighbors.

Do we have a source for the altitude data ?
Does stage separation occur after burnout or is there some ballistic coast involved?

OK, I answer myself!

The first stage burnout is indeed 100~120km. So the indicated figure is consistent.

My Unha-3 addon does that at around 90-100km. In fact, right after the sep, the MP3 music kicks in (which is indicative of reaching "space" in Orbiter...btw I changed Bach's "Air" to the NOKOR national anthem just for kicks LOL).

Well, is KSP:
A. The Kerbal Space Program?
Or B. The Korean Space Program?
