If the weather doesn't play nice, NASA has backup launch dates lined up from April 2-6.
Mark Burger, the primary launch weather officer for Artemis II, "Historically, almost half of all rocket launches that end up scrubbed have been a result of unsafe weather," said Burger.
The team is taking no chances: they're tracking everything from lightning (even the kind rockets can trigger) to solar activity and ocean conditions where astronauts might land if needed.
Safety comes first before liftoff.
