Quite some time ago, these were in the news, but I noticed this morning that
these are being blamed for small shorts on Cassini now. With the ISS being life extended etc, i wonder how long it will be before we hear about hese here. I find it odd that according to the Cassini story, they are still not really sure why these occur. Its definitely something one will need to stop if we want to live on other planets I'd suggest. Do they only occur in microgravity, or is it some interaction due to radiation and free radicals or maybe ionised gas.

Brian back when I was still working, we were having a real issue with Silver Migration in the touch pad control panel membranes takes a while for some issues to come to the forefront. |

They are a natural property of some low-melting-point metals, well-known on Earth. Consult http://en.wikipedia.org/wiki/Whisker_%28metallurgy%29. They are not to be confused, of course, with Electric Whiskers : http://en.wikipedia.org/wiki/Annibale_Bergonzoli. -- (c) John Stockton, near London.
