[MCU] Why didn't Thor use the Bifrost?

At the beginning of End Game when Rocket determined Thanos was on Titan why didn't Thor use Stormbreaker to bifrost everyone to Titan?  He could have teleported everyone there in the blink of an eye rather than 1+ months to fly a spaceship there instead.

It's possible that Titan II was outside of the Nine Realms which means Yggdrasil and therefore the Bifrost wasn't connected to it.

Regardless, the ship was plenty fast, it definitely wasn't a month (that's closer to how long Tony and Nebula were stranded in space).
