Rosetta's comet target, 67P/Churyumov-Gerasimenko, has emerged from behind the Sun as seen from Earth, and the Very Large Telescope has photographed it. The new images show that cometary activity has already begun as Rosetta approaches for its August rendezvous.
Here's the next installment in the continuing story of how the Mars Express team is preparing for Comet Siding Spring flyby, 19 October 2014. This week: introducing the spacecraft's subsystems and structure – and wondering how we can absorb impacts.
Today's post continues where we started last week with an update from the Mars Express Flight Control Team at ESOC on their preparations for the 19 October Comet Siding Springs flyby. Today: defining the challenge!
On Sunday, 19 October 2014, at around 18:30 UTC, comet C/2013 A1 – known widely as 'Siding Spring' after the Australian observatory where it was discovered in January 2013 – will make a close fly-by of Mars.
You thought you were rid of us...but we're back! Following the spectacular and, quite frankly unprecedented, success of the Comet ISON Observing Campaign, we are launching a similar venture for another unique cometary encounter that's happening this year. In October 2014, comet C/2013 A1 (Siding Spring) will pass extremely close to Mars.
Comet ISON captivated our world, and many of our world’s robotic emissaries for many months. But, alas, poor ISON is dead -- again. Here I wrap up our enthusiastic coverage of this multi-morphing zombie comet that tried to survive and re-survive as it came within one solar diameter of the Sun.
