Comet C/2013 A1, also known as comet Siding Spring, will graze the planet Mars on Sunday within about 139,500 km, less than half the earth-moon distance. Spacecraft orbiting around mars are getting prepped for the encounter.
Launched in 2004, the Rosetta spacecraft has finally arrived at comet 67P/Churyumov-Gerasimenko. It will be the “first mission in history to rendezvous with a comet, escort it as it orbits the Sun, and deploy a lander to its surface”. Follow the event live at: More
As the ESA’s Rosetta spacecraft closes to within 1000 km of Comet 67P/Churyumov-Gerasimenko, the Rosetta science team has released a new image and made the first temperature measurements of the comet’s core.
