To one extent or the next, we've already been doing this.
The notion that we are 'sterilizing' our robots before we send them to places like the Moon, Mars and Titan is something of a misconception. The act
of completely sterilizing is one thing... but then to keep it sterile? That's quite another. These spacecraft and their landers may be exceptionally
'clean', but sterile they are certainly not.
There is a kind of 'space kills' theory that says that between the dense cold, lack of oxygen (or any other gas) and naked solar radiation, most
bugs hitching a ride on our spaceships will be dead by the time they reach their destinations. But in the lab, some bacteria have shown they can
hybernate in the cold, airless vacuum of space and with a dose of cosmic radiation, they actually grow some in the process.
What happens when they get to... wherever? Who knows? Maybe one day, we will meet a Martian coming home to find his relatives on the bathroom sink.
