It was perhaps the most unique artifact found by earthlings who finally entered space. A transfer station abandoned near Venus, long forgotten by the owners - Aliens. A station where people discovered a lot. But first of all - SHIPS Alien ships created according to unknown to us, "alien" technologies. Ships that could fly VERY FAR. And if you accidentally "press the right button" - you can even return... And people obsessed with the call of distant stars began to learn to fly. And - flew away.
