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 Rosetta spacecraft has been orbiting the 67P/Churyumov-Gerasimenko comet for two years. Now scientists have ended the mission, and the spacecraft has lost contact with Earth forever.

At around 10:30 am EST Wednesday morning, a small probe named Philae made history — by becoming the first spacecraft to ever land on a comet. After a seven hour journey down from Rosetta, the ...

Rosetta's historic 12-year mission 30 photos. The European Space Agency’s $1.6 billion Rosetta spacecraft completed a deliberate crash landing on the surface of comet 67P/Churyumov-Gerasimenko ...

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.

Read news, see photos and watch videos about the Rosetta mission's landing on Comet 67P/Churyumov-Gerasimenko scheduled for Nov. 12.

The European Space Agency’s Rosetta spacecraft descended to a gentle mission-ending crash landing on comet 67P/Churyumov-Gerasimenko early Friday, beaming back a final series of increasingly ...

The European Space Agency's Rosetta spacecraft arrived at its target, Comet 67P/Churyumov-Gerasimenko, today (Aug. 6) to end a 10-year journey across the solar system. The spacecraft performed an ...

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.

Rocket scientists at the European Space Agency’s mission control here erupted in cheers, as they received the first signal that the probe that was released from the Rosetta spacecraft had ...
