There were 3 orbital launches on March 29 2018:

  • Soyuz 2-1v
  • GSLV Mk.2
  • Long March 3B

Is it a record tie for most orbital launches on the same day (as expressed in local time)?

If so, when it was set? If not what is the record and when it happened?

    $\begingroup$ As the beginning and the end of a day is not the same all around the planet, I suggests either you precise wich time to use (UTC is one possible choice) or you slightly modify your question replacing "in one day" by "in 24 hours" $\endgroup$

  • $\begingroup$ @Manu Local date was the same for all listed launches. That is the principal of the question. $\endgroup$ Commented Mar 31, 2018 at 19:03

  • $\begingroup$ en.wikipedia.org/wiki/… Here's a decent timeline on wikipedia. (Says it's unsourced, includes failures, successes and non-orbital flights). Could probably filter that by type and get a rough idea. $\endgroup$ Commented Apr 2, 2018 at 18:14
  • $\begingroup$ @MagicOctopusUrn thanks! Using your link I found that there were 3 orbital lauches on December 21-st 2005! It is a good candidate for the record, I will try confirm if it is indeed the day when the record was set. $\endgroup$ Commented Apr 2, 2018 at 19:09

Thanks to the link provided by Magic Octopus Urn, I found that there were 3 orbital launches on February 14 1989:

  • Molniya-M from Plesetsk
  • Kosmos-3M from Plesetsk
  • Delta II from Cape Canaveral

The record was tied

  • on February 28 1990
  • on August 28 1990
  • on March 25 1993
  • on June 25 1993
  • on March 22 1995
  • on December 21 2005
  • on June 15 2010
  • and recently on March 29 2018

There are currently 5 orbital launches scheduled for the 24 hour period starting at midnight UTC on 4th August 2022 There is also a New Shepard launch with human passengers scheduled for the same day. If all of these occur successfully then the record will be broken.
