Launch means hold-down clamps releasing after engine ignition, regardless of subsequent success or failure.
"Launch" is defined as the vehicle lifting off the pad, however slightly, under thrust from its engines.
Only launches planned to be orbital or near-orbital (intended to come within ~5% of orbital velocity) count.
Relevant timezone, for determining which month a launch is in, is local time at the launch site.
Edit Nov 9th: changed the definition of "launch". It turns out that the launch clamps may be released well in advance of ignition, such that they should not be used as part of the defintion of "launch"

@Eliza Main thing it depends on is how much they want to change before flying another one, I think. The way IFT4 went they don't need a mishap investigation. Otoh if they want to tower-catch then the license might need more scrutiny.
"The FAA's Kelvin Coleman says at the #payloadspacecapitol event this evening that he didn't see any major issues with last week's Starship launch, but SpaceX still needs to carry out a mishap investigation. SpaceX, he says, is aiming for 6-9 more Starship launches this year."

Chris holds No in every month, looks like there will be zero launches this year

@Eliza It's not clear if the next launch will be the same planned trajectory as the previous one or not. We can see regulatory filings that imply a different trajectory, including full orbit and a powered landing in the Indian ocean, as opposed to a slightly suborbital trajectory and an unpowered splashdown near Hawaii. Most think this new trajectory will apply to the third flight, but it might apply to the fourth and I don't think we have official confirmation yet.
Other than that, I think just the usual slew of incremental improvements, including lessons learned from the previous launch, as well as the differences that existed already between the vehicles that launched last and will launch next, since they're all different as SpaceX is improving things anyway. The first launch was fairly old hardware that they had already improved on considerably.
I'm not sure about specific improvements though. I think they're still going for the same hot-staging.
There were articles about them potentially demonstrating an internal propellant transfer in orbit:
Which would be practice for something they'll need to do for the upcoming Artemis missions. No confirmation they'll be doing this yet, but you'd imagine it would require full orbit since the vehicle otherwise wouldn't be in space for very long.
Traders, in light of discussion here, I have modified the definition of "launch" that resolution will use. It turns out that the hold-down clamps may release well in advance of engine ignition, making them quite irrelevant to what people are likely betting on. Resolution will instead depend on "actual lift off from the pad".
@Joshua Still bugged? I saw @firstuserhere created a new unlinked multi, does that mean they're OK now?
@chrisjbillington They're fixed now but selling is still restricted. I think you should be ok to open them. @Joshua can you confirm?
