Since its arrival at comet 67P/Churyumov-Gerasimenko, the European Space Agency’s Rosetta spacecraft has been surveying the surface and the environment of this curiously shaped body. But for a long time, a portion of the nucleus — the dark, cold regions around the comet’s south pole — remained inaccessible to almost all instruments on the spacecraft. […]
After more than a decade traveling through space, a robotic lander built by the European Space Agency has made the first-ever soft landing of a spacecraft on a comet. Mission controllers at ESA’s mission operations center in Darmstadt, Germany, received a signal confirming that the Philae lander had touched down on comet 67P/Churyumov-Gerasimenko on Wednesday, […]
This image of comet 67P/Churyumov-Gerasimenko, taken by Rosetta’s Optical, Spectroscopic, and Infrared Remote Imaging System (OSIRIS) on Sept. 20, from a distance of 4.5 miles (7.2 kilometers), shows jets of dust and gas streaming into space from the neck of the comet’s nucleus. Images of the comet nucleus, taken by Rosetta earlier in the summer, […]
After a decade-long journey chasing its target, the European Space Agency’s Rosetta, carrying three NASA instruments, became the first spacecraft to rendezvous with a comet. The last of a series of 10 rendezvous maneuvers that began in May, to adjust Rosetta’s speed and trajectory to gradually match those of comet 67P/Churyumov-Gerasimenko, occurred today (Aug. 6, […]
