The Sims 4: Aliens and Space Rocks

Completing Rocket Science Collections

The Sims 4 Rocket Science allows you to complete Alien and Space Rock Collections
Alien and Space Rock Collectibles

Rocket Science will reward you with two things for completing Collections. Space Rocks will give you an Orchid for your Garden, which is a plant that is very hard to get otherwise, and completing the Alien Life Collection will give you a plaque for the wall. You will sometimes get these collectibles without anything in particular happening on a mission. Many rewards are random, though completing both of these collections should not be particularly challenging.

Just discovered that if you have multiple dead space aliens and have an alien in your household they can revive the duplicates to help you finish your collection.

Nice! Always fun to discover new things. We have a guide that covers this here. Aliens can also transmute other collectibles so they can be relatively handy to have around.
