On a October 3, 2020{{Cite web|last=Burghardt|first=Thomas|date=2020-10-02|title=SpaceX scrubs fourth GPS III satellite launch|url=https://www.nasaspaceflight.com/2020/10/spacex-line-launch-fourth-gps/|access-date=2020-11-01|website=NASASpaceFlight.com|language=en-US}} launch attempt of a GPS III-04 was aborted two seconds prior to liftoff due to, two engines on the 1st stage starting up earlier then expected. Following the abort the engines were sent to SpaceX's engine testing facility in Texas. In response to the issue SpaceX and NASA delayed the launch of Crew-1 that was expected to occur on October 31, 2020 to allow time for data review.

An investigation found that a relief valve in the Merlin's gas generator was blocked with redish masking lacquer, used to protect it while other parts of the generator are anodized. The clog caused pressure in the gas generator to rise faster then expected, causing the engines to automatically shutdown. Though unlikely, had the engines not been shutdown shaking could have caused damage. SpaceX stated that an outside vendor who was responsible for anodizing had not removed the protective lacquer properly after the process. The failure of the cleaning process had been speculated to be possibly due to using less cleaning fluid. In addition, SpaceX stated that the clog was overlooked due to the narrowness of the valve. Following the discovery SpaceX inspected other engines to find similar issues and took corrective actions to prevent similar problems in new engines.

Starting with List of Electron launches (Which I split away from Electron (rocket) pages) there seems to be increase in articles which split the list of launches from their respective launch vehicle pages. What should (or should there be) a criteria when a split becomes necessary?

When I split the List of Electron launches my intent in was because of Rocket Lab's claim that they will have frequent launches and that would cause the article to become too long. In hindsight this is probably WP:CRYSTAL.

Recently I noticed that there are similar pages or drafts being created:

• Draft:List of Delta 4 Medium launches (currently part of Delta IV, List of Thor and Delta launches (2000–2009), and List of Thor and Delta launches (2010–2019))
• Draft:List of Delta 4 Heavy launches (currently part of Delta IV Heavy)
• Draft:List of Antares launches (currently part of Antares (rocket))
• Draft:List of Atlas LV3A launches
• Draft:List of Minotaur launches (currently part of Minotaur (rocket family))

• List of Vega launches (originally in Vega (rocket)
• List of Delta 4-M launches (originally in not sure)

{{Excerpt|Lists of rocket launches|Lists of rocket launches by rocket}}

The new pages do add new info in some cases (I like some of the new graphs in particular like "orbit"! - maybe other list of pages can add them too). But also some of the lists have the formatting changed from the original which I found confusing. OkayKenji ^{(talk • contribs)} 00:49, 1 March 2021 (UTC)
