North Korea's Military Reconnaissance Satellite "Malligyong-1"

Deleted posts relating to a BBC article on food shortages in North Korea. It it is a political discussion better off elsewhere, or every topic on development of any government funded project or system could be filled with similar arguments about better uses for the money.
 
NHK:North Korea informed Japan that it would launch a satellite from 24th to 31st this month.

The splash zone of this launch seems to be the same as the last launch.

North Korea's second spy satellite launch fails

It appears the rocket carrying the satellite flew further than during the previous attempt.
www.bbc.com www.bbc.com
A news report in state-run KCNA blamed the failure on "an error in the emergency blasting system during the third-stage flight", and said the problem was "not a big issue".
It seems the rocket carrying the satellite flew further than during the previous attempt. Officials in Pyongyang had described the botched attempt in May as their "gravest failure" while vowing to try again.

Chilling details of Vlad & Kim’s talks as tyrants hail ‘sacred war on West’

VLADIMIR Putin and Kim Jong-un vowed to fight a “sacred” battle against the West after having talks and a lunch in Kim Jong-Un’s honour. The North Korean leader told Putin that he…

Asked if Russia would help Kim build satellites, Putin replied: "That's why we came here. The leader of the DPRK shows great interest in rocket engineering, they are also trying to develop space."


North Korea experienced failures in recent months as it tried to place a spy satellite into orbit - but has vowed to try for a third time in October.

I didn't know it has one. On the other hand, now I know what Kim and Putin had for grub.
 
Well, one can supose that if a member takes the time to post a source here (a moderator, no less), he/she has estimated that it was a worthwhile addition, not just anything-to-up-my-post, count even at the cost of lowering the signal-to-noise ratio, like too many newbies do.

As a personal opinion, if a source is known to have zero value, then it has no place on spf.
Maybe in the Bar if it was somehow entertaining.

The signal-to-noise ratio is the most valuable asset of this forum, and it is better nurtured ex ante than after the fact. And frankly, --as a general observation unrelated to the OP--, it is not going up at the moment. I'd plead that we try to watch it and refrain from posting anything less than professional and constructive, at least in the Projects and General sections. The Bar and the Speculation sections are the outlet for the rest, if it needs one.
 
Do these better satisfy your sensibilities?

Kim Jong Un’s Trip to Russia May Help Him Put Spy Satellites in Orbit

North Korean leader Kim Jong Un is returning from Russia with pledges to help with his space program that could finally allow his country to reach its long-held goal of placing multiple satellites in orbit.

How could Russia help North Korea build a satellite?

North Korean leader Kim Jong Un on Wednesday toured Russia's most modern space launch centre, where President Vladimir Putin promised to help Pyongyang build satellites.
www.reuters.com www.reuters.com


the entire point was that there has reportedly been discussions about Russia assisting Nth Korea in terms of satellites.
 
KCNA:
The NATA of the DPRK reported to Kim Jong Un that the reconnaissance satellite "Malligyong-1" would formally start its reconnaissance mission from December 1 after finishing 7 to 10 days' fine-tuning process.

Anderson has a lot of cloudy days.
 
Any news on possible 2nd Satellite ? Can't really have just 1. They would need some more for either wider coverage or more frequent update.

Yes, they announced more launches next year.
And also this one was their 3rd consecutive attempt within a year, after all - with apparent improvements b/n launches.

North Korean agile development.

May I ask what the speculation is based on? :oops:

Kerolox is the most volumetrically efficient first stage liquid rocket available. I mean, it's what the US used to get to the Moon!

Methalox is cheaper but requires a larger fuel tank.
 
Three more reconnaissance satellites will be launched in 2024.

Report on 9th Enlarged Plenum of 8th WPK Central Committee

The conclusion clarified the task for the field of space development to launch in addition three reconnaissance satellites in 2024 on the basis of the experience gained in the successful launch and operation of the first reconnaissance satellite in 2023 and referred to the nationwide full-scale measures for dynamically accelerating the development of space science and technology.

KCNA Report on Accident in Launch of Military Reconnaissance Satellite
kcna.kp kcna.kp

English version of the official report
note the use of "The launch failed due to the air blast of the new-type satellite carrier rocket during the first-stage flight" and "a preliminary conclusion that the cause of the accident is attributable to the reliability of operation of the newly developed liquid oxygen + petroleum engine".

Chollima-1 used Hypergolic engines (presumably russian-derived) on its first stage, this may be an upgraded, or different, launcher.
 
The launch used a new type liquid oxygen+kerosene engine(액체산소+석유발동기)
석유 means petroleum, But sometimes it also can be means kerosene

It seems that south korean experts and analysts are taking this announcement of North Korean "Kerolox" engine development seriously.

North Korean launch systems continue to be progressively separated from their missile systems.

Probably, if they're reverse engineered/inspired from russian engines.
We don't know which grade of kerozene they're using.

Or developed out of open literature on the Saturn V 1st stage engines. Kerolox is pretty simple and really good for a first stage engine. Lots of mass going out the nozzle makes lots of thrust.

The North Koreans aren't stupid, despite some of the dogma that comes out of their political apparatus. (Then again, see also the dogma that comes out of any other nation's political class...)

A rather [inadvertently] funny article from the wsj,whoever wrote it apparently doesnt seem to know theres a difference between hydrogen and hydrazine,or maybe they were getting it mixed up with hydrogen peroxde or hypergolic,who knows?.:rolleyes:

North Korea’s Fiery Spy-Satellite Test Shows More Than Failure

"In the past, North Korea appeared to have relied on hydrogen as fuel and so-called “red fuming nitric acid” as the oxidizer necessary for rocket combustion"

"Nations with advanced space programs have also moved away from using hydrogen, due to the toxic substances released as fuel burns, the lengthy fueling time and the higher rates of explosion, said Hong Min, head of North Korean research at the Korea Institute for National Unification, a state-funded think tank in Seoul."

Well,that clearly explains it all then.The articles author was talking to an "expert" from a "think tank".
Mystery solved.;)

Sorry to break it for you, but KINU is a state-run national policy research institute, not just some random "think tank", along the likes of Heritage Foundation and Co.. It's just the author of the WSJ article being an idiot who doesn't know Hypergolics are not Hydrogen.
