After a decade-long quest spanning six billion kilometres (3.75 billion miles), a European probe will come face to face Wednesday with a comet, one of the Solar System's enigmatic wanderers.
The European Space Agency (ESA) will on September 15 announce which of five possible sites it has chosen for the first-ever landing of a probe from Earth on a comet, it said Thursday.
On October 19, 2014, Comet Siding Spring will pass by Mars only 132,000 km away—which would be like a comet passing about 1/3 of the distance between Earth and the Moon.
Hundreds of millions of miles from Earth, a speeding European spacecraft released a lander toward the icy, dusty surface of a comet on Wednesday, setting off a seven-hour countdown to an audacious attempt to answer some of ...
NASA is taking steps to protect its Mars orbiters, while preserving opportunities to gather valuable scientific data, as Comet C/2013 A1 Siding Spring heads toward a close flyby of Mars on Oct. 19.
Robot probe Philae uploaded a slew of data to Earth Friday from a deep-space comet that it drilled into long after its onboard battery was feared to have died.
Feeling lucky? Events such as the Comet Siding Spring approach by Mars in October only happen about once every eight million years, according to NASA.
(Phys.org) —Less than a week before Rosetta's rendezvous with comet 67P/Churyumov-Gerasimenko, images obtained by OSIRIS, the spacecraft's onboard scientific imaging system, show clear signs of a coma surrounding the comet's ...
In new images of comet 67P/Churyumov-Gerasimenko taken by Rosetta's onboard scientific imaging system OSIRIS, surface structures are becoming visible. The resolution of these images is now 100 meters per pixel. One of the ...
(Phys.org) —A new analysis of data from the ESA/NASA Solar and Heliospheric Observatory (SOHO) spacecraft has revealed that comet 2012/S1 (ISON) stopped producing dust and gas shortly before it raced past the Sun and disintegrated.
