Do you think all astronauts are smart? It is definitely not about these guys, because they are sure visiting a black hole is quite a funny idea. Your mission is to save them!

Though, even worse is to catch them with portals of inappropriate color - energy fields overload will destroy portals and the last hope of the astronauts.
