It's our turn.
The second after the order was issued, the entire command room began to run like a machine. Every researcher and engineer sitting in the room began working, like gears turning a clock.
In the orbit of Mars tens of millions of kilometers away, the black metal ball was driven by a small electric propulsion engine. This controlled the position of the ball in the orbit.
A large hexagonal bulge on the clock was pointed at another Z particle clock, floating in geosynchronous orbit tens of millions of kilometers away.
A piece of the ball shell moved to the side, exposing the complex and delicate optical parts.
A solemn order was heard in the command center.
"Turn on the laser aligner."
The signal transmitted from the ground command center was received by the alpha Z particle clock floating in the geosynchronous orbit.
