For a billion miles, the tireless spacecraft called Rosetta has shadowed an icy comet through the solar system, enduring dust storms, fountains of gas and the comet’s mood swings.

The perfect alignment of the sun, Rosetta probe and Comet 67P allowed the spacecraft to snap a shadow selfie that was sent back to Earth.

The Rosetta spacecraft casts some shade on the surface of its comet buddy, creating an otherworldly shadow selfie from orbit.

The spacecraft that conducted previous comet missions blew by their targets at more than half a mile per second or far faster, whereas Rosetta will travel at a leisurely 3 feet or so per second.

On Wednesday morning the Rosetta spacecraft kept a 10 year date with an icy comet the size of a mountain.

The Rosetta mission comes to an end as spacecraft touches down on surface of comet 67P/ Churyumov–Gerasimenko.

The Rosetta mission will reach its climax on Wednesday when scientists attempt to land a spacecraft on a moving comet. Here’s why we should all be excited.

The Rosetta spacecraft hibernated for 31 months while its orbit took it too far away from the sun for its solar arrays to keep it operational. It's ready for a rendezvous with a comet Aug. 6.
