When rocket launches are scrubbed at the last minute, what happens to the fuel? Is it offloaded into the storage tanks or vented into surrounding air?

Answer 1

It’s *never* released into the environment intentionally. It’s pretty much always pumped back into tanks that initially fueled the rocket unless the launch scrub was some non-mechanical reason (like weather) and another attempt will be made soon.
