Brazil satellite launch

Brazil has successfully launched a satellite earlier this year. Should it be added to the launch-capable countries? ^[1] ^[2]

Arab sat question, and citations for dates

What is the proper country attribution for the Arab Sat satellites? I'm referring to this string of edits, all of which are in good faith (there was a typo earlier that's been corrected), but I'm not sure if the 1985 launch, or the 2000 launch should be listed.

In a related note, there needs to be a lot better attribution with cites for all of these dates. Dates like this are often targets of vandals making subtle changes, and adding in citations is the best way to combat that. Obviously people adding in specific dates have some source they're reading from. Shadowjams (talk) 22:22, 21 February 2013 (UTC)[reply]

Arabsat is a Saudi Arabian company; it does have a multinational element (as do several other similar companies), however it is primarily Saudi Arabian, and its satellites are considered Saudi Arabian. --W. D. Graham 11:27, 22 February 2013 (UTC)[reply]

Contradiction within the first two sentences

"In the context of spaceflight, a satellite is an object that has been intentionally placed into orbit. These objects are called artificial satellites to distinguish them from natural satellites such as Earth's Moon."

These two sentences contradict each other, or at least semantically very much not clear what satellite is, only artificially orbited objects are satellites or what. 91.82.182.182 (talk) 22:05, 19 January 2022 (UTC)[reply]

"In the context of spaceflight" part removes the contradiction. In the context of spaceflight, the term "satellite" is synonymous with "artificial satellite," and need not have the "artificial" qualifier. --OuroborosCobra (talk) 23:06, 19 January 2022 (UTC)[reply]

Then I propose the opening sentence to be a generic definition, not specific use cases. 91.82.182.182 (talk) 13:46, 20 January 2022 (UTC)[reply]

OTOH the Satellite disambiguation starts with "A satellite is an artificial object which has been intentionally placed into orbit, such as:" so I don't even know anymore. It's murky, and needs some rewording for sure, but I don't know how. 91.82.182.182 (talk) 13:47, 20 January 2022 (UTC)[reply]
