Voyaging, for Almost Four Decades

This beautiful image was produced by NASA to commemorate the anniversary of the Voyager spacecraft, which were launched in August and September of 1977. 

We'll soon be closing on 40 years since the launch of Voyagers 1 and 2. These missions have done so much for planetary science and are still alive, continuing to send data back to us about the space environment along their travels. They may last as much as another 5 or 10 years before they run so low on power that all of their instruments shut down. 

Even after the Voyagers have shut down their instruments and died, they will still travel; out there amongst the stars, the furthest reach of humanity, they will continue on.
