It does but it is generated from the raw infobox extractor that greedily
guesses the datatype
dbpprop:cosparId 1987 (xsd:integer)

You can create a new class on your own or use a similar class
(not a domain expert but the most related are under
the MeanOfTransportation or Device)

You can (should) change the range to xsd:string

the above uri should be http://dbpedia.org/ontology/cosparld
Actually all classes / properties are under the dbpedia-owl (http:
dbpedia.org/ontology/) namespace. classes start with uppercase and
properties all lowercase

We also have the following documents, they are kind of old but the basic
mapping function didn't change
https://github.com/dbpedia/extraction-framework/tree/master/core/doc/mapping_language
For easier mappings you can use the following chrome extension developed by
Andrea Di Menna
https://github.com/dbpedia/mappings_chrome_extension
and there is also this mailing list ;)
We also welcome documentation contributions on the wiki
For this specific case you should create a new mapping for the "infobox
spaceslight"
http://mappings.dbpedia.org/index.php/Mapping_en:Infobox_spaceflight
