North Korea and named after a Chinesepoetry byKim Il Sung . It is the first class of satellite built by this country and the program started in the1980 s.First orbital launch
On occasion of the 50th anniversary of the founding of the DPRK, the official
Korean Central News Agency announced onSeptember 1 st,1998 Juche 87, that a satellite called "Kwangmyŏngsŏng-1" had been launched at 3:07UTC onAugust 31 from a launch site inMusudan-ri , Hwadae-gun, North Hamgyong Province by aBaekdusan-1 SLV. This launch made the DPRK the ninth spacefaring nation, after theUSSR ,USA ,France ,Japan ,China ,UK ,India andIsrael .

According to
North Korea Academy of Science 's AcademicianKwon Tong Hwa , the SLV was developed in the1980 s when the late leaderKim Il Sung decided to launch a Korean satellite. At the beginning of the1990 s, the capacity to achieve this goal was already reached.On occasion of
Kim Jong Il 's 50th anniversary, onFebruary 16 th,1992 , his fatherKim Il Sung presented him one of his Chinese calligraphedpoetry . Referring to his son's birth, an event that was reportedly marked by a double rainbow, and a bright star in the sky, the future Korean SLV and satellite would be named after it:cquote|一顆誕生於聖山白頭山正日頂峰的“光明星”, 將成為文武雙全、忠國孝親, 受萬民稱頌擁戴的傑出領袖。
From the eternal snowy summit of our sacred Baekdusan Mountain, A Bright Star shall rise.

South Korea 's first satelliteUribyol 1 akaKitsat 1 onAugust 10 th,1992 and its second satellite,Uribyol 2 akaKitsat 2 , onSeptember 26 th,1993 , both by an EuropeanAriane 4 SLV. In a late-1993 meeting of the Korean Workers’ PartyCentral Committee ,Kim Il Sung expressed his desire to place quickly a satellite into orbit, leading to the expansion of the DPRK’s nascent space program and the requirement for a space launch vehicle.The
Baekdusan-1 SLV (「運輸火箭白頭山一號」)is the civilian version of theTaepodong 1 IRBM (「大浦洞一號」), with an additional spin up solid motor orbital insertion third stage. The first and second stages of the SLV are made up ofNitric acid /UDMH liquid propellant rocket engines and the third spin-up orbital insertion stage of a solid propellant engine. The first stage consisted of a No-Dong 1MRBM and the second stage of a Hwasong-6SRBM , a derivative of the Scud-C. The third stage is derived from the ChineseHQ-2 booster.In designing the "Kwangmyŏngsŏng-1", the DPRK received considerable assistance from the
PRC ’s Academy of Launch Technology. This assistance has continued with development of the "Kwangmyŏngsŏng-2" satellite project. It may also extend to additional satellites, including a crudereconnaissance satellite .Launch campaign
Thus, only five years later, preparations for the first satellite launch began at the Musudan-ri Launch Facility on
August 7 th,1998 . Two weeks later,KPN vessels proceeded to their mission area into theSea of Japan (East Sea of Korea). By that time, South Korea had already placed two other satellites into space with Delta-7925 SLVs,Koreasat 1 akaMugunghwa 1 akaEurope Star B onAugust 5 th,2005 andKoreasat 2 akaMugunghwa 2 onJanuary 14 th,2006 .Liftoff occurred at 12:07 hours local time on
August 31 st. The first stage was separated from the rocket 95 seconds after the launch. The fairing shroud separated at the 144th second, then the second stage separated itself from the rocket at the 266th second. The third stage put the satellite into orbit 27 seconds after the separation of the second stage.Aftermath
Confirmation of the launch and detection of the satellite by the Space Tracking Center in Moscow has quickly been reported by the
Russian Space Agency . [cite web|url=http://bbs.tiexue.net/post2_1391730_1.html|title =朝鲜导弹和卫星的发展概况|publisher=铁血社区 |date=2006-07-07|accessmonthday=September 25|accessyear=2008]This was followed on
September 14 th by a video of the launch, images of the satellite, and an animation of the satellite in orbit. The photographs showed a satellite similar in shape with a 72 faced tetrahedron, to the first Chinese satellite,Dong Fang Hong I , itself very similar toTelstar 1 , though the Kwangmyŏngsŏng-1 was largely outclassed in mass (42㎏ vs 173㎏ for the DFH-1) and size (35㎝×35㎝×35㎝ vs 100㎝ ×100㎝ ×100㎝ for the DFH-1).According to the North Korean media it completed its hundredth orbit on
September 13 ,1998 , and was in an elliptical orbit with a perigee of 218.82 km and apogee of 6,978.2 km with a period of 165 minutes and 6 seconds. It was also reported to be transmitting the melody of "Song of General Kim Il-sung " and "Song of General Kim Jong-il " and the Morse signals "Juche Korea" at 27 MHz, as well as orbital data including temperature, pressure and conditions of power source.Thus, scientific foundations were laid for the development of future telecommunications satellites.
Controversy
NORAD were unable to detect the satellite visually, by
radar , or pick up its radio signals, reporting instead that it continued east, burning up, with a debris trail that apparently extended to approximately 4,000 ㎞. It is thought that the satellite launch appeared to have failed due to underperformance of the solid fueled third stage, placing the satellite into an orbit from which it decayed very quickly. But there is some doubt in adversary nations as to whether the satellite existed at all. Many of their observers arguing the story of a satellite launch was invented to allay the western outrage that followed North Korea's test-firing of a “Taepodong-1 ballistic missile”, which crossed overJapan before crashing into thePacific Ocean . Following the test, Japan’s Self Defense Forces even went to sent three destroyers and patrol aircraft to extensively search the impact areas in the Pacific for wreckage of the alleged “missile and its warhead”. Expectingly, all these efforts have been in vain.econd orbital launch
On its
December 26 th,1998 edition, theRodong Sinmun already announced that North Korea would launch another satellite in the future.In a very controversial series of missile test conducted on the occasion of the American National Day on
July 4 th,2006 , according to the internet edition of theChoson Sinbo (「朝鮮新報」) published onJune 21 st,2006 , the payload of theBaekdusan-2 SLV (「運輸火箭白頭山二號」) civilian version of the Taepodong 2C/3ICBM (「大浦洞二號」) could have been made of the "Gwangmyeongseong-2 " (「光明星二號」)weather satellite , with a mass ranging from 170 ㎏ to 550 ㎏. Launched from theMusudan-ri launch center, the rocket failed after only 42 seconds.Tenth anniversary
On occasion of the 10th anniversary of the
1998 Kwangmyŏngsŏng-1 satellite launch attempt, program conducted by North Korea in close cooperation withIran andPakistan , theIranian Space Agency has proceeded with its own test. According to practice also observed byNorth Korea , Iranian authorities announced to their Chinese allies onAugust 16 th,2008 the incoming imminent launch of a satellite.

Reza Taghizadeh, head of the Iranian Aerospace Organization, told state television "The Safir (Ambassador) satellite carrier was launched today and for the first time we successfully launched a dummy satellite into orbit". [citeweb|title=Iran says it has put first dummy satellite in orbit |url=http://news.yahoo.com/s/nm/20080817/wl_nm/iran_satellite_dc_4|publisher="Reuters "|accessdate=2008-08-18]On occasion of the 10th anniversary official celebrations,
Radio Pyongyang broadcasted onAugust 31 st,2008 and received inChina , pledged not only for further satellite launches of the Kwangmyongsong series but also for the resumption of its nuclear program starting with the reactivation of theplutonium -producing Yongbyon nuclear plant shut down only a year early.

September 11 th,2008 , supporting previous claims to launch more satellites into space, the existence of a totally new launch facility exceeding both in size and sophistication the Musudan-ri test base on North Korea's east coast has been revealed. Known asTongch'ang-dong Space Launch Center (平安北道鐵山郡同昌里同昌洞發射基地)and located in theNorth Pyongan province at coord |39.660|N|124.706 |E|, it is built on the former site of a small village calledPongdong-ri . Thus, the first stage of aBaekdusan-1 SLV would land in the Sea of Japan at about coord |39.433290|N|129.472213|E|. Indeed, the old Musudan-ri test center was not designed for winter time operations but only for the occasional space satellite launch campaign in the spring, summer or fall seasons, the SLVs being not easily prepared for launch.The new space center includes a movable launch pad and a ten storeys tall tower capable of supporting the DPRK's largest SLVs, including a rocket motor test pad similar in size and design to the IranianShahid Hemmat rocket test facility built east ofTehran . There are also support buildings, a vertical assembly building and an engine test stand among other structures. Following the relocation of scores of new aerospace factories far away from theDemilitarized Zone , it is specially built in the mountainous North West part of the country, closer to the Chinese allied border, at only 50 km of it and therefore benefiting from the Chinese airspace protection, the site is consequently meant to be safer.

Baekdusan-2 SLV engine ignition test have already started.

The satellite has since featured prominently in North Korean festivities and celebrations such as the
mass gymnastics . Commemorative stamps showing the real shape of the satellite still attached to the spin up solid motor orbital insertion third stage and more than two orbits have also been printed on several occasions.
