A delicate piece of metal and glass drifts through the expanse.
The probe GILGAMESH is a revolution in space travel technology. Its ion drive thrusters are amplified by the magnetic fields generated by on-board superconductors. As the material gets colder, the field gets strong enough to tear hydrogen molecules to shreds and fuse them together, generating more energy and thrust.
It is a costly method, though. To reduce weight and cost, most of the GILGAMESH's interior is composed of intense radioactive shielding for its hardware, and there is no room for passengers. All it can do is fly straight forward, take pictures, and send them back to Earth.
At this point, it has been traveling for one hundred and forty-eight years, six months, twenty-two days, and nine hours. It has managed to get far in that time- seven light-years into the void. As it passes another frigid planet, it does its daily routine of measuring temperatures and light refractions, taking photos, and sending them back to Earth. It can only go further until it crashes into an uncharted asteroid, and there may not be anybody back at home to receive the data. But still, it goes on, just as it was programmed to do a century and a half ago, searching for something it may never find, and finding what it could never have hoped to see.
