April 12 has Yuri's Night to commemorate Yuri Gagarin's first orbital flight by a human.

The launch of Sputnik 1, the first satellite humanity put into orbit, on 4 October 1957 at 10:58pm Moscow time is at least as important event, but I'm unaware of any organized events to commemorate the occasion.

In any case, Happy Sputnik Day! (It’s a national holiday for those of us who are citizens of the #L5Nation, celebrate it appropriately!)

This is picture of the day # 4727 on PhotoByFred.com:

  • I hear there was supposed to be a question about it on SpaceExploration SE @FKEinternet, keep an eye out for it. – GdD Oct 4 '17 at 20:01

There were a few things that were done, namely:

  1. A number of news articles.
  2. Events at planetariums
  3. Events at the Smithsonian/ other museums

I'm sure there were other events too, but I can't find references. I can't find any in Russia itself, interestingly enough.
