Or worse, you meet the super intelligent giant spider your human ancestor left behind, and you accidentally start a war with them because no one realizes the computer on the ancient satellite is made to behave like the project founder is trying to make first contact.
Tap for spoiler
The project founder accidentally died, the computer AI fails to keep them alive and the spiders start to think the satellite is a god. Then they enslave the native ants.
The big problem is no one remembered to tell the humans on Earth about the experiment. Or the humans on the generation ship that knew died centuries ago.
EDIT: If you haven’t figured it out, I’m describing the novel Children of Time by Adrian Tchaikovsky.
