Resolves to number of successful launches of all variants of orbital launch vehicles on Nextspaceflight's Manifest Page.
https://nextspaceflight.com/launches/?q=&f=agency_1&tab=
for March 2026, UTC time.
If that page is demonstrably wrong or out of date, then I will either wait for update or a correct source will be decided upon and used as a replacement.
A launch is considered successful if it is outlined in green on the linked manifest page.
Launches outlined with red (failure) or orange (partial failure) will not count as successful.
(Starship is considered an orbital launch vehicle, regardless of true orbit not being demonstrated. Success may well be more of an issue with test flights.)
My understanding of how nextspaceflight colours launches is that the launch ends with payload deployment. Therefore a problem with payload deployment could result in orange or red outlining for partial failure or failure. A failure after this like a deorbit burn failing has been shown outlined in green previously. As long as the outline colour is not clearly wrong resolution will be based on the outline colour.

A satellite launched by a viable organisation like NASA that carries a SpaceX satellite doesn't count.
@AlanTennant Correct but I am not sure if there are any examples of that, SpaceX launch all their own satellites AFAIK.
@AlanTennant Works on nextspaceflight page. If payload is successfully deployed they outline it in green for success. So a failure to deorbit after payload deploy such as Feb 7 2026 launch is shown in green and counts as successful not unsuccessful.
