Is the checklist/programme they are reading through available anywhere?
Is that how they did it with Mercury or were those names announced before the launch?
No. The names were revealed long before launch and were actually painted on the side of the Mercury spacecraft.
Sorry. What is "launchnet" that is constantly referenced as an update source? I cant seem to find it by a quick search. Is it a closed information source?
