It’s not enough for some Sims to just shoot for the stars inThe Sims 4– they’d actually like togothere, and thanks to the Rocket Science skill and a steadfast commitment to maintaining a rocket ship, now, they can.
You don’t need to be working in the Astronaut career in The Sims 4 to build the Rocket Science career, though. Even those with a curiosity about universe (and the Simoleons to fund a pricy hobby, if the tinkering isn’t for work) are able to build a rocket ship in their back yard and set off into the stars.

Rocket Science Skill Overview
For those luminary Sims in The Sims 4, the sky can’tpossiblybe the limit - they’reoff to spacein their backyard ships with theRocket Scienceskill.
Tobegin building the Rocket Science skillin The Sims 4, you’ve got a couple of options.

You can:
There’s only one ship available to start with, theSteampunk Flyamajig, which costs5,000 Simoleonsto buy and can be found in theActivities and Skillstab.
But when you first buy the Flyamajig, you’ll receive only parts - your Sim needs tobuild the ship from scratch.

The process will take themseveral hoursto complete and will likely need to spana few daysif they’re working alone.
However, once you’ve finished, your Sim unlocks a third option to build their skill: they can now gain the Rocket Science skill bygoing to space themselves.
