The story before this Friday: :ahem:


Rockin' Naro Style

Rockin' Naro Style......Naro Style.....

We Koreans have great things for the world
Of kimchis, Samsungs, Hyundais and LGs
Then we look for something harder to do
How about a rockin' rocket?

Then all things go wrong
Then Uncle Sam says no more playing with dangerous things
Then Kim Jong Il shoots bright stars into space and damned the capitalists
But all three stars met only one same ugly fate
Felling over our heads

So we say this
Why not shoot a rocket into space and say Hey!
And do it twice! Hey!
But we can't build a whole rocket by our hands alone
So what can we do?
So what shouldn we do?

We wanna wanna wanna wanna naaaaaaaaaaaaaaaaaaa our
Rockin' Naro Style! Oh!......Naro Style.....Rock rock rock rockin' Naro Style! Oh!......Naro Style......Rock rock rock rockin' Naro Style!

Heyyyyyyyy! Rocket engineers!.....Rock rock rock rockin' Naro Style!
Heyyyyyyyyyyyyy! Rocket engineers!.....Rock rock rockin' hey hey hey hey hey hey!

We Russians at Khrunichev had not much money left
Trying to build that much better rocket named Angara
Did that for dozen years and we got not much done but .ppt
What should we do next?

Then the Koreans call us
Asking us to build the first stage to orbit for their rocket
We think this is a really good idea for rubles
So we signed the papers and got to do some work on the ground
Or so we say

We made a large two stage rocket in record time
Put it on a platform (hey!) on Naro-on-the-seaside (hey!)
One August afternoon we lighted the candle
And watched the white arrow flying in the blue sky (hey!)
But then the bad news came (hey!)
That the fairing went on strike above the airrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr darn it!

Rockin' Naro Style! Oh!......Naro Style.....Rock rock rock rockin' Naro Style! Oh!......Naro Style......Rock rock rock rockin' Naro Style!

Heyyyyyyyyyy! What happened with our satellite? Rock rock rock rockin' Naro Style!
Heyyyyyyyyyy! What happened with our satellite? Rock rock rockin' hey hey hey hey hey hey!

We tried again
In Twenty and Ten
Babe babe we launched again into the June blue sky
And watched it disappear
As the computer system went Kaputnik
Babe babe it made our rocket go kaboom!
And made us really upset on how it goes

Rockin' Naro Style!

Heyyyyyyyyyy! You pay your bunch of rubles! Rock rock rock rockin' Naro Style!
Heyyyyyyyyyy! Why should we give you our Won paper bills! Rock rock rockin' hey hey hey hey hey hey!

Rockin' Naro Style!

Oh!

....

Rockin' Naro Style!


To be continued...... this Friday!

:rofl:



Note: For those who are serious when looking at this post, it is just a joke that I hope it can record how difficult the project for a South Korean rocket launcher and the Angara project has reached the state today. Hopefully this will also be the celebration song for success on Friday! :cheers:

For those who are not familiar with the story of South Korea's attempts to become the tenth country to have the organization ability to launch payloads into orbit (although this "membership" isn't worth as much as the other nine, as quite a lot of rocket parts are imported from elsewhere), here's the story:

In 1998, the "neighbors" from the North made their first "satellite launch" (:shifty:), and of course it did not reach orbit. But it seems to have exerted pressure on the South Koreans, for their aerospace research institute responded with a small orbital launcher of their own in a year or so.

The problem is, while the Koreans have a decent ability to build satellites, their experience with rocket propulsion and guidance is rather limited (one reason is because the US limited their attempts to build short range missiles). So they were forced to give up on it being a completely made-in-Korea product, and look for help elsewhere for the first part towards orbit.

They find assistance in Khrunichev, one of Russia's largest space industry firms. Khrunichev was at that time lacking enough rubles to continue Russia's next generation launcher family, the Angara, past the .ppt stage. The money from the Koreans was a great help, as it would also provide chances of proving in flight the Angara's Universal Rocket Module I (URM-I), which would serve as the standard first stage and boosters for the whole rocket family. The two sides (KARI and Khrunichev) eventually signed a contract for building the rocket's first stage and launch facilities in October 2004.

The resulting rocket is a really strange one: while the first stage is a prototype for the Angara's first stages, powered by the 167 tonne thrust RD-151 kerosene engine, a scaled-down version of Angara's RD-191 and a distant relative to Atlas' RD-180 and Zenit/Energia's RD-170. After burning for about 4 minutes, it separates and the upper stage coasts for about 2 minutes before it kicks into action. The tiny solid upper stage (thrust level only at 8 tonnes!) is build by the Koreans, and unlike most other solid upper stages, it has a full-blown thruster system for attitude control. It burns for about 2 minutes to push the satellite into orbit. Maximum payload is estimated at around 800 kg to a polar low Earth orbit.

The launch site is the Naro Space Center on Naro island, on the southern Korean coast 450 km south of Seoul. The site, with the help of the Russians for the construction, looks rather similar to other Russian launch sites.

As for what happened during the first two launch attempts in August 2009 and June 2010? Well you will know after clicking into the links above. ;) Put it simply, the project has been suffering from co-ordination issues between the Koreans and the Russians. :facepalm:

Photos and reports about this third (and possibly the final) attempt for the project will come later, after I find time to write a bit while dealing with multiple homework assignments and tests. :) In the meantime, here are good places to look for details:

The rocket was rolled out of the integration building and erected on the launch pad on Wednesday. Today a launch rehearsal was held that cleared the way for tomorrow's launch. Liftoff remain on schedule at 06:30 UTC (3:30 pm local time), at the start of a 3.5 hour long launch window.

The payload is STSAT-2C, a 100 kg satellite that carries several experiments for testing in orbit:

  • the Laser Retro-reflector Array (LRA) allows the spacecraft to be tracked with centimeter accuracy by satellite laser ranging (SLR) stations which make up the International Laser Ranging Service (ILRS).
  • a Langmuir probe will be used to determine the electron temperature, electron density, and electric potential of plasma.
  • the Space Radiation Effects Monitor (SREM) will be used for measurements and monitoring of the near-earth space environment.
  • in addition, the Reaction Wheel Assembly (RWA), IR Sensor (IRS), and Femto second Laser Oscillator (FSO) are carried for the verification of new space technologies

I'll post the Orbiter scenario for the launch in the next few hours....
 
Launch delayed by at least three days due to gas leakage on the first stage. Hopefully it won't when it flies..... :shifty:

(rocket launch) S. Korea moves to launch Naro-1 space rocket

By Byun Duk-kun
NARO SPACE CENTER, South Korea, Oct. 26 (Yonhap) -- South Korea began making final preparations Friday as it remained just hours away from its planned launch of a space rocket in its third attempt to send an indigenous satellite from its own soil.

The Korea Space Launch Vehicle-1 (KSLV-1) was expected to be launched between 3:30 p.m. and 7 p.m., with the exact time to be announced at 1:30 p.m. after final inspections and weather checks, according to the Korea Aerospace Research Institute (KARI), the main South Korean developer in the ongoing space program.

Friday's launch, if it takes place, will be the country's third attempt to send the KSLV-1, also known as Naro-1, into space after its two earlier tries in August 2009 and June 2010 ended in failures.

The rocket development program began in 2002 when the country decided to develop its own means to transport satellites into space. The country has so far sent up 10 satellites into space, but all using foreign rockets.

A lack of relevant technology, however, forced the country to seek help from Russia, which launched over 3,100 space rockets from 1950 to 2011 and has a success rate of 93.6 percent.

The space program has so far cost some 520 billion won (US$471 million).

The first-stage rocket of the Naro-1, built by Russia's Khrunichev State Research and Production Space Center, can generate a 170-ton thrust to carry the South Korea's indigenous Science and Technology Satellite-2C (STSAT-2C) to an altitude of 193 kilometers in just 232 seconds after liftoff.

The second-stage rocket of the KSLV-1, jointly developed and built by KARI and some 150 other South Korean institutes and companies, will further take the STSAT-2C to an altitude of 305 kilometers.

From there, the satellite will move into the proper orbit on its own, using solar panels as its energy source and moving at a speed of 8 kilometers per second.

The time from the launch to the actual deployment of the satellite is only 9 minutes, but much depends on the success of Seoul's third and last attempt with the KSLV-1.

Regardless of the success or failure of the Naro-1 program, Seoul is moving to develop a 10-ton thrust engine by 2016 and a 75-ton thrust engine by 2018.

Still, the success in the Naro program will ensure more confidence in developing and building the country's first indigenous space rocket, KARI officials said.

"The success of the Naro-1 that can put a 100-kilogram satellite into orbit is important in that it will offer confidence in our rocket design and technology, but more importantly, it will have a significant meaning as a stepping stone for the development of an indigenous launch vehicle," Kim Seung-jo, president of KARI, said earlier.

Whether or not the ongoing Naro space program is successful will become clear when the satellite, STSAT-2C, makes contact with a ground station at the Korea Advanced Institute of Science and Technology about 13 hours after the launch.

Space Travel: S. Korea rocket launch set for Nov 29:
South Korea plans to go ahead with a delayed rocket launch on Thursday next week in its third bid in four years to put a satellite into orbit, officials said.

If all goes as scheduled, the 140-tonne rocket will lift off between 4:00-6:55pm (0700-0955 GMT) from the Naro Space Centre on the south coast, the Ministry of Education, Science and Technology said.

OK nothing on their English channels, so it's down to screenshots of the Korean TV channels.....

T-15 minutes and counting.

Edit: Launch on hold right now....

Apparently the launch is on hold for at least 30 minutes due to telemetry signal issues....
