Talk:Soyuz-U

Citing sources
Can someone (perhaps the anon. IP editor who made the edit) explain why the source citation I had added regarding the launch of Progress M-62 was removed? I'm bewildered, trying to imagine why someone could possibly choose to remove a source citation without even commenting on doing so. I suppose of course the right thing is to think it was an oversight. Thus I have restored the source citation. (sdsds - talk) 02:09, 24 December 2007 (UTC)

Soyuz-U launch statistics
The launch statistics (714 launches / 19 failures as of Feb 2008) looks incorrect or/and obsolete. The manufacturer web-site states 756 launches / 20 failures as October 20, 2009. If the manefacturer's numbers are correct then it must be at least 761 launches / 20 failures as October 2010. Does anybody have more accurate data? 65.200.157.178 (talk) 21:36, 19 October 2010 (UTC) Andriy Andreyev October 19, 2010

Shuttle for safety/reliability comparison

 * I added STS (Space Shuttle) launch stats for comparison, but I don't believe it's possible to say one or the other is safer; the STS has a better launch rate, but the smaller sample group may make the difference not statistically significant (depending on how you define the confidence interval). Also, I suspect a majority of the Soyuz failures were early on, and revisions and experience since then has likely made it safer.  So that's why I list the data without making conclusions.  —Preceding unsigned comment added by 69.98.164.95 (talk) 04:50, 31 January 2011 (UTC)

Last Flight
Was yesterdays flight (1 October 2015) the last one? — Preceding unsigned comment added by 87.164.248.115 (talk) 08:15, 2 October 2015 (UTC)


 * I think there are at least 2-3 more flights left, all with future Progress flights (MS-3/4/5 in 2016/7, with MS-1/2 flying on the Soyuz-2.1a). Meanwhile, the plan to switch future Soyuz HSF flights to the Soyuz-2 rocket series seems to have been halted. Galactic Penguin SST (talk) 14:09, 2 October 2015 (UTC)

The script for getting this data is here - User talk:Barecode/Space Statistics - replace Voskhod with Soyuz-U and delete lines containing Soyuz-U2. -- Barecode (talk) 23:12, 21 December 2021 (UTC)
