When the European Space Agency's Rosetta spacecraft discovered abundant molecular oxygen bursting from comet 67P/Churyumov-Gerasimenko (67P) in 2015, it puzzled scientists. They had never seen a ...

UPDATE: 6:23 a.m. EDT — The Rosetta spacecraft is now less than 1 km (0.62 miles) away from the surface of comet 67P/Churyumov-Gerasimenko, where it will slowly crash-land to end its mission.

Rosetta, a European Space Agency mission, orbited and crash landed into Comet 67P from 2014 to 2017. It also sent its companion, the Philae lander, to the surface of the ice ball.

Comet 67P, whose elliptical orbit takes it past Jupiter and then closer the Sun every 6.4 years, was still far from the Sun when Rosetta began its duties.

Images sent back by ESA's Rosetta probe show that it wasn't only thing orbiting comet 67P/Churyumov-Gerasimenko (67P/C-G). A comparison of images taken four years ago when the comet was closest to ...

With its phenomenally successful Rosetta orbiter and Philae lander mission to Comet 67P/Churyumov-Gerasimenko, the European Space Agency (ESA) finally got the kind of well-deserved global ...

Published: March 21, 2017 10:34am EDT It is almost six months since the Rosetta spacecraft completed its operations in a controlled dive onto the surface of comet 67P/Churyumov-Gerasimanko.

Comet 67P/Churyumov-Gerasimenko is a small body visited by two spacecraft in 2014: the Rosetta orbiter and the Philae lander. The European Space Agency mission — usually collectively referred to ...

Rosetta’s travels with 67P began in August 2014, after a convoluted 10-year journey across 4.9 billion miles of space.

Rosetta had already been lying in its lonely resting place 485 million miles away on comet 67P/Churyumov-Gerasimenko for nearly an hour, because of the 40 minutes it took for radio signals travel ...
