Comet Siding Spring Mars encounter: One Mars Express plan becomes two

Posted by ESA Mars Express Team on 2014/09/17 10:44 CDT | 2 comments

The Mars Express Flight Control Team at ESOC have been actively preparing for the flyby of comet C/2013 A1/Siding Spring on October 19. Initial estimates gave the possibility that Mars Express might be hit by 2 or 3 high-speed particles. Happily, additional observations by ground and space telescopes have shown the risk to be much lower – and perhaps even as low as zero. In today's blog post, the team explain how this (happy!) real-life, real-time development is affecting their preparations for fly-by.

So Close and Yet So Far: Why isn't Siding Spring going to sandblast Mars?

Posted by Tony Farnham on 2014/09/09 09:02 CDT | 5 comments

Comet Siding Spring is going to make a very close approach to Mars in October. Any comet dust that reaches Mars has the potential to inflict significant damage on the spacecraft orbiting the planet. As it turns out, however, Mars and its orbiters are likely to see very few, if any, impacts. Why?
