I would post my radar question there but it seems blind people are not
allowed to do so as there is a verification image on the response page.

So your question was How does the ISS program detect and avoid
collision with larger chunks of space debris such as the Chelyabinsk meteor?

As an aside: I assume from your posting that you are blind. If so may I
ask how your are reading these postings? Are you using a Braille touch
interface or text-to-voice? If the latter, does it translate things like
smileys?

I now realize I might need to change the way I use smileys to denote
sarcastic or humorous commentary...
