Too fast, Too factory

There are a few ways to achieve this (e.g. building a hyperloop cannon) - but one easy way as soon as you've unlocked the Jetpack is in the HUB building; once you reach a milestorne and hit the big red button, immediately go outside and jetpack up to sit on top of the drone on the roof. There's enough time to get there before it takes off. You can then ride it almost to space - which will unlock this achievement.

You'll also die. So save first and reload after.
