Usage and ambiguity with mission[edit]
I want to make sure I understand the best way to use this. Sometimes the mission can be confused with the spacecraft that is being identified with the COSPAR ID. A case where that is clear and generates an error is Apollo 11 (Q43653), which shares a COSPAR ID with CSM-107 (Q28101301). I think the most accurate/proper way in this case is:
- Apollo 11 (Q43653), no COSPAR ID (P247)
- CSM-107 (Q28101301), COSPAR ID (P247) of 1969-059A
- New instance of S-IVB (Q257161) named Apollo 11 SIVB, COSPAR ID (P247) of 1969-059B
- Eagle (Q28101302), COSPAR ID (P247) of 1969-059C
A less clear case is for Sputnik 1 (Q80811). The satellite and the upper stage of the rocket were both assigned COSPAR IDs. Sputnik 1 (Q80811) refers to both the mission and satellite. So is the following correct?
- space launch vehicle (P375) in Sputnik 1 (Q80811) with property COSPAR ID (P247) defined as 1957-001A (though technically not true as 1957-001A is for only a part of Sputnik (Q1393751)
- Sputnik 1 (Q80811) with statement COSPAR ID (P247) defined as 1957-001B
This same logic would apply for most if not all cases of SCN (P377) and Harvard designation (P5049).
I am new to Wikidata, let know if I did not clarify the ambiguity well or if I misused terminology, or if I need to advertise this question at other venues. Thanks for any assistance. Kees08 (talk) 21:58, 6 April 2020 (UTC)
Confusion with NSSDCA ID[edit]
There seems to be some confusion about how the COSPAR ID is related to the NSSDCA ID. These are two separate catalogs maintained by separate organizations. Most of the time the NSSDCA equals the COSPAR ID for a given object. However, many times the two ID numbers are different for the same object. For example: Lemur-2 https://nssdc.gsfc.nasa.gov/nmc/spacecraft/display.action?id=LEMUR2105, AESP-14 https://nssdc.gsfc.nasa.gov/nmc/spacecraft/display.action?id=1998067FM, Lightsail-2 https://nssdc.gsfc.nasa.gov/nmc/spacecraft/display.action?id=2019036AC
I have received confirmation from a NASA representative about this. The above examples are not errors. Any time the COSPAR ID is longer than 9 characters, the NSSDCA ID will be different due to their internal system limitations.
I would like to propose that a new property be created called NSSDCA ID to account for these differences. Item Q96142561 (Lightsail 2) technically has the wrong COSPAR ID due to this issue.Spacepat o (talk) 19:41, 19 October 2020 (UTC)
