North Korea reported the launch of its first satellite on the first of September. This announcement was followed on September 14 by the release of a photograph of the satellite and the claim that the satellite had completed its 100th orbit of the earth between 08:24 and 11:17 local time (2017 GMT) on September 13. Video of the launch, the satellite, and an animation of the satellite in orbit around the earth were distributed to foreign news agencies the following weekend. The satellite appeared almost identical to the first Chinese test satellite (which itself appeared almost identical to the US Telstar).

Despite these claims no foreign observer ever detected the satellite visually, by radar, or picked up its radio signals. The Pentagon at first claimed it was an ICBM launch, and that the satellite story was just a cover for the test. However on further analysis of the data collected on the launch they admitted nearly a month later that there had been some a satellite launch attempt. What seems to have happened is that the third stage either failed and fell into the Pacific or misfired and put the satellite into a low orbit where it decayed very quickly before it could be detected by foreign observers.

Third North Korean satellite launch attempt, conducted despite international protests (that attempted to connect it with the country's missile program). Launched from a new site on the west coast of Korea on a southwest trajectory, to achieve a polar orbit and also avoid overflying Japan. Failed at first stage separation. Unusually North Korea provided the western press access to the launch site prior to the attempt, and admitted the launch failure after the fact.

First successful North Korean satellite launch. Amateur observations showed the satellite to be tumbling, and no signals were picked up at the announced 470 MHZ frequency - it was assumed the spacecraft never functioned or failed shortly after orbital insertion.

North Korea's National Aerospace Development Administration (NADA, Kukga uju gaebalkuk) carried out its second successful satellite launch . The satellite, Kwangmyongsong-4, entered a 500 km polar orbit like the KMS-3-2 satellite launched in 2012. It appears both satellite and launch vehicle are very similar to the 2012 mission. The launch vehicle this time carried the name 'Kwangmyongsong' but appeared to be essentially identical to the Unha-3 launched in 2012. As of Feb 17, hobbyist observers had not picked up any radio signals from it. 0840LT SSO.
