Siding Springs and Mars

It is all happening - Siding Springs, or comet C/2013 A1, will miss Mars on Oct 19, by only 132,000km, about 1/3 of the distance from Earth to Moon. There are several satellites currently orbiting Mars that will be able to observe this event.

Michael Khan has been busy again:

One needs good weather, and then the time and energy, the idea, and ability!
Well done Michael.

His blog is also an inspiration for me. Michael and I first met in Feb 2004
before the launch of Rosetta.
