EN001 US space object (payload) not registered with the United Nations but recorded in the COSPAR Bulletin and allocated an international designation. Space object reentered prior to first US report to the United Nations. EN002 US space object (payload) not registered with the United Nations but recorded in the COSPAR Bulletin and allocated an international designation. Object launched subsequent to the first US report to the UN. EN003 US space object (non-functional) not registered with the United Nations but recorded in the COSPAR Bulletin and allocated an international designation. Space object reentered prior to first US report to the United Nations. EN004 As EN003, but not in COSPAR Bulletin. Data taken from NASA-GSFC Satellite Situation Report. EN005 United States Space Object 1961 Alpha Lambda 1 was registered as an object of type D (non-functional); other evidence suggests that it was really of type A, and so it has been included in the main list. EN006 US Debris object not registered with the United Nations. EN007 USSR space object not registered with the United Nations EN008 The document swaps inclination and period for two of these objects, the obvious error has been corrected. EN009 Editor's note: A/AC.105/INF.54 gives the apogee as 5620. This is probably a misprint for 562.0. EN010 Editor's note: 1964-04A inclination as given in A/AC.105/INF.63 was 85.50 deg. This was a typo for the correct 81.50 deg. EN011 Editor's note: 1964-07A recorded in A/AC.105/INF.63 as being in heliocentric orbit. It was actually on a lunar impact trajectory. EN012 Editor's note: A/AC.105/INF.104 gave the inclination as 359.86 deg; this is an error for 0.14 deg. EN013 Editor's note: A/AC.105/INF.118 gave inclination as 5 deg; this is an error for 65 deg. EN014 A/AC.105/INF.131: Orbit given is spurious. EN015 A/AC.105/INF.140: 1966-40D is a typo for 1966-40B. EN016 A/AC.105/INF.142: 1965-109C is a typo for 1965-109D. EN017 A/AC.105/INF.155: 1966-104O, recorded as debris with the same details as 1966-104P, is spurious and did not exist. EN018 A/AC.105/INF.174: 1967-26D, registered in a 605 x 623 km x 56.1 deg orbit, is spurious. It is a mistake for 1967-27D which is a USSR debris object not registered with the UN. EN019 A/AC.105/INF.187: 1968-02A registered as category D, but is actually a category B object. EN020 A/AC.105/INF.192: Cosmos 221 perigee was given as 22 km, this is a typo for 220 km. EN021 Orbit given was 163.3 min, 188 x 500 km x 84.6 deg. This orbit is clearly spurious. EN022 A/AC.105/INF.45: 1962 Beta Tau 2 recorded as no longer in orbit on 1963 Jul 15. This should have read 1962 Beta Tau 3. EN023 Object, registered by the United States, is a Canadian payload. EN024 Object is an Apollo Lunar Module. Although registered as category D, should really be category A. EN025 Object, registered by the United Stages, is actually an ESRO payload. EN026 Editor's note: A/AC.105/INF.216 incorrectly reported the decay of 1969-51A in the period ending 1969 May 31. EN027 Object, registered by the United States, was a payload for the Federal Republic of Germany. EN028 Object, registered by the United States, is a United Kingdom payload. EN029 A/AC.105/INF.223: Orbital data given for 1970-21A were 1401.6 min, 40807 x 42164 km x 2.8 deg. The semimajor axis and orbital period are inconsistent with Kepler's third Law. It appears that distances from the center of the Earth instead of heights above the surface were used; a reasonable orbit is obtained by subtracting the Earth radius of 6378 km from apogee and perigee, and I have used that result in the table. EN030 Space object launched by the People's Republic of China and not registered with the United Nations. EN031 The registration document for USSR launches number 439 to 449 appears to have been omitted from the A/AC.105/INF series. The information tabulated has been taken from the COSPAR Bulletin. EN032 1971-00A is actually 1962 B Lambda 2. 00B is 1964-86B. 00C is 1964-86C. EN033 A/AC.105/INF.234: The orbital data for Cosmos 421 and 424 were erroneously repeated for Mars 2 and Mars 3, which should not have been given any orbital data. EN034 1971-91A is debris from the Delta rocket which failed to place its payload in orbit. I have included this category D (non-functional) object in Table 1 since the RAE tables suggest that the object is the Delta rocket itself, and rocket stages for launch vehicle tests (e.g. Saturn and Centaur) have been counted as payloads. Further, this avoids a confusing gap in the table. EN035 A/AC.105/INF.280 registered object "1969-27KH", an error for 1969-82KH. EN036 A/AC.105/INF.291 registered 1973-100D as an object of category C. External evidence strongly suggests that it was actually of category D, and hence is included in Table 2. EN037 A/AC.105/INF.227 registered this object as 1963-38H. It was later redesignated 1963-49K but this was not noted in the UN reports. EN038 A/AC.105/INF.295 registered this object as 1963-384. This was a typo for 1963-38H. EN039 A/AC.105/INF.295: Apogee was given erroneously as 4.7 km. EN040 A/AC.105/INF.298: The English version of this document incorrectly transliterated the name as Molniya-1C. EN041 A/AC.105/INF.339 contained the cryptic information: "Supplemental information - DAD-A/B". This was expanded on A/AC.105/INF.342 to "The following object was launched since the previous report but did not achieve orbit - DAD-A/B". This is an allusion to the launch failure of the DAD-A/B satellites, and to be consistent with earlier data on launch failures should have read - Object failed to achieve orbit: 1975 Dec 5, Scout, Category B. EN042 Category given as C; should be category D. 1977-118A, not registered by the US, would have qualified as category C. EN043 Name erroneously given as Soyuz 21. EN044 ST/SG/SER.E/7: Orbit given as 591.75 min, 6560 x 40137 km x 27.8 deg. Inconsistent with Kepler's third law. I have given values which assume that the compilers of the UN submission forgot to subtract off the Earth radius of 6378 km from the perigee and apogee heights; this gives a consistent orbit. EN045 ST/SG/SER.E/7 gives orbit as 720.0 min, 805 x 34272 km x 63.5 deg. This is inconsistent with Kepler's third law. I have been unable to find a simple error which could have generated these parameters from a sensible orbit. The given orbit heights correspond to a period of 613.5 min rather than 720.0 min. If the apogee only were in error, the orbit would be 805 x 39681 km. I have replaced these parameters in Table 1 with the orbit parameters given in SER.E/7 for the rocket body, 1978-21B. EN046 Registered in ST/SG/SER.E/47 as 1965-27C - a typo for 1965-27G. EN047 Category given as D, but carries a payload - should have been designated as category A, B or C. EN048 ST/SG/SER.E/11: Orbit given as 615.5 min, 6528 x 41411 km x 28.4 deg. Inconsistent with Kepler's third law. I have given values which assume that the compilers of the UN submission forgot to subtract off the Earth radius of 6378 km from the perigee and apogee heights; this gives a consistent orbit. EN049 ST/SG/SER.E/16 - Orbit given as 101.3 min, 17 x 146 km, which is impossible. Other sources indicate that a decimal point has slipped in the heights, which should be about 170 x 1460 km. EN050 ST/SG/SER.E/16 - Registered as 1978-78B, should have been 1978-78C. EN051 ST/SG/SER.E/16 - Apogee of 1978-79A was given as 108920 km, but should have read 1089200 km. EN052 ST/SG/SER.E/19 - 1978-93A orbital heights were given as 86 x 10825 km. These values were actually nautical miles (to be consistent with the orbital period) and I have multiplied them by 1.852. EN053 ST/SG/SER.E/40 - 1966-96C orbit given as 597.7 min, 33889 x 35783 km x 17.8 deg. This orbit is impossible. EN054 The four Pioneer Venus Probes, which impacted Venus on 1978 Dec 9, were registered in ST/SG/SER.E/47. The only information given for each was the international designation, the launch date, and the fact that they were no longer in orbit on 31 Dec 1980. EN055 Minor typo corrected in orbital parameters. EN056 First satellite in this group of 8 given in report as Cosmos-1308, an error for Cosmos-1320. EN057 Typo in ST/SG/SER.E/77: registered as 1976-32K instead of 1976-23K. EN058 Registered as category D (non-functional) object, but external sources suggest the object is a payload. EN059 Apogee given as 2.7 km, which is a typo. EN060 Registered under an incorrect international designation (typographical error in document). EN061 Orbital heights given in ST/SG/SER.E document are in error - they conflict with the orbital period. I have subtracted off the Earth radius of 6378 km to give a consistent orbit. EN062 Debris from Zenit rocket test launch. No payload was orbited. Not registered by the USSR. EN063 Orbital period is incorrect - ST/SG/SER.E/141 gives it as 639.8, which was the orbital period in the transfer orbit, while the orbital heights given are for the final orbit. EN064 ST/SG/SER.E/194 gave entirely spurious orbital data for 1988-18A and 1988-26B: the orbits for 1988-06A and 1988-06B were given instead of the correct orbits. EN065 The launch vehicle given is incorrect. EN066 ST/SG/SER.E/208: Orbital period inconsistent with heights. Correct orbital period for quoted heights would be 261 min, not 99.8 min. Correct apogee with 99.8 min period and 151 km perigee would be around 1300 km. EN067 Orbital period given is incorrect; perigee and apogee heights are consistent with external information, and correspond to a larger orbital period. Alternate decay info: Prior to 1994 Jul 31, in ST/SG/SER.E/278. EN068 JCSAT-2 launch vehicle is really Titan III; MUSES-A launch site is really KAG. EN069 ST/SG/SER.E/250: Orbit given for 1990-90D in the registration document really applies to 1990-93B. 1990-90D is in heliocentric orbit. EN070 ST/SG/SER.E/260: Registered as launched from the territory of the United States; launch was actually from French territory, as correctly noted in the later French registration in ST/SG/SER.E/287. EN071 Satellite not registered with the UN; belongs to INMARSAT, an international organization with headquarters in the UK. In ST/SG/SER.E/417/Rev.1, the UK provided details of these satellites and acknowledged that INMARSAT was headquarted in the UK, but explicitly denied that it was the state of registry for these satellites under Res. 2777 (XXVI), Res 3235 (XXIX), etc. Nevertheless it is hard to see what the state of registry for these satellites should be, if not the UK; I have assigned responsiblity to the state providing launch services. EN072 Orbit is spurious. EN073 Inclination is spurious. EN074 1975-52B exploded into many fragments (1975-52D onwards). Many of the orbits tabulated for these fragments in ST/SG/SER.E/258 are clearly corrupted, but are presented here anyway. EN075 Registered as category B, but really category D. Orbital period for 1991-54E is incorrect. EN076 ST/SG/SER.E/258 quotes an orbit of 113.9 min, 1399 x 1427 km x 82.6 deg for the US military satellite 1991-76C. This orbit actually belongs to the USSR satellite Cosmos-2165 (1991-77A). EN077 This satellite was re-registered in ST/SG/SER.E/258 with the erroneous designation 1992-15B and orbital data 93.9 min, 450 x 483 km x 43.1 deg. EN078 Orbital period calculated from orbit heights. Period tabulated was 133.6 min, a factor of 100 too low. EN079 ST/SG/SER.E/262 gives the name of the satellite as Resurs-300, but this is an obvious typographical error. EN080 Orbital period is spurious. EN081 ST/SG/SER.E/275 gives the name of the satellite as Cosmos-TM-17, but this is an error for Soyuz TM-17. EN082 Orbital heights are spurious and probably refer to 1995-01A which was omitted from the registry. Orbital period and inclination, however, are correct. EN083 The German/Japanese EXPRESS satellite is believed to have completed several orbits before reentry, but was not allocated an international designation or a US Space Command catalog number. EN084 ST/SG/SER.E/287 gives name as SPOT. This is incorrect; name is S80/T. EN085 ST/SG/SER.E/300 gives international designation as 1994-056A, which is incorrect. State of registry changed from UK to China with effect from 1 Jul 1997. EN086 ST/SG/SER.E/301 gives 'general function' as 'Spent boosters, ... non-functional objects'. This is incorrect, the object is a communications satellite payload. EN087 State of registry changed from UK to China with effect from 1 Jul 1997. EN088 Orbital data for 1995-060A and B are spurious - period and height disagree. Period and inclination refer to the transfer orbit, while apogee and perigee refer to operational orbit which has a period about 1436 min and inclination close to zero. EN089 SAC-B (Argentina), HETE (USA) and the final rocket stage remained attached. Argentina cataloged SAC-B; USA cataloged the object as a debris object, but should have cataloged HETE, so it is included in the main table. EN090 ACE, in solar orbit. No orbit or description given in registration data. Description added in ST/SG/SER.E/339. EN091 Orbital data are for lunar orbit. EN092 Originally registered as category D (non-functional) object, but external sources suggest the object is a payload. Registration corrected in ST/SG/SER.E/353. EN093 Zarya is an American-owned space station module built and launched by Russia. In Russia's registration data in ST/SG/SER.E/354, Zarya is noted as 'American registration'. However, the United States erroneously omitted Zarya from its registration submission. EN094 Spurious orbital data registered for 1999-03A. EN095 Incorrectly registered with launch date 9 Aug 2000 in ST/SG/SER.E/375. EN096 Also incorrectly registered by US in ST/SG/SER.E/385; really a Swedish satellite. EN097 Registered by USA in ST/SG/SER.E/385. First registered by UK in ST/SG/SER.E/378 but retracted in ST/SG/SER.E/389 since the launch was procured by GE Americom in the USA. EN098 Perigee is spurious, probably a typo for 36432 km. (ST/SG/SER.E/384). EN099 Also registered by the US in ST/SG/SER.E/400. EN100 Also registered by the US in ST/SG/SER.E/412. EN101 Also registered by ESA in ST/SG/SER.E/432 EN102 Orbital data for 2007-41A and 2007-41B were swapped. Data for 41A should read 94.4 min 482 x 496 km x 97.5. EN103 Spurious orbital data; spacecraft was on Earth escape trajectory. EN104 Orbital data given in registration document is erroneously measured from Earth center. EN105 Registered by the UK in ST/SG/SER.E/554 and the US in ST/SG/SER.E/514. EN106 Orbit module mentioned but not designated separately in registration document. EN107 Originally registered by the US in ST/SG/SER.E/412. Satellite was jointly owned by US and France. EN108 FASAT-A registered by Chile in ST/SG/SER.E/660. Satellite remained attached to Sich-1 in orbit. EN109 Apogee/perigee given in registration document are erroneously measured from Earth center rather than surface. EN110 China registration of this satellite in SER.E/649 noted that Nigeria is also a launching state for it.
