> Get ready for humans to change the orbit of another rock in space for the first time in history

I don't understand. Change the orbit of another rock

and

for the first time in history.

How can changing an orbit of another rock be the first in history?

My english is not a native level.

"Another" here doesn't mean we've done it before. You're supposed to interpret it as "Change the orbit of a rock".

I'm assuming "Another" refers to "A rock that is not earth." Though that does seem rather confusing.
