The first amazing news (http://www.space.com/news/090211-satellite-collision.html) is that the Iridium-33 satellite was obliterated by a highly improbable collision with long-dead Soviet Cosmos-2251 satellite ~800 km over Siberia.

Totally unrelated, except for the news appearing on Space.com: one of our old-time AMSATers is also in the news on Space.com. The Feb. 5th edition carried a very interesting article on a long-time AMSAT supporter, Greg Roberts, ZS1BI. For those of you who don't know Greg, an interesting Hearsat "Ask The Expert" autobiographical (& how-to) article can be found at http://www.hearsat.org/content/ask-expert-greg-roberts.
For many years Greg was a well-known Variable Star Observer http://books.google.com/books?id=NoHxiPAkptYC&pg=PA367&lpg=PA367&dq=%22greg+roberts%22+SAAO&source=bl&ots=W9Z8CWnl2C&sig=1YIcgl5kNbe3LCN9v6hCtj6_ZY4&hl=en&ei=6dWTSf3rC8e_tgfIhKCgCw&sa=X&oi=book_result&resnum=9&ct=result affiliated with the South African Astronomical Observatory (SAAO) in Capetown and has been a very active amateur astronomer, well known for his visual tracking of satellites. See here http://www.saao.ac.za/%7Ewgssa/as3/roberts.html and also here http://www.saao.ac.za/%7Ewgssa/as4/greg.html to see Greg's very interesting notes about visual observing of satellites. A photo of Greg can be seen here http://www.space.com/php/multimedia/imagedisplay/img_display.php?pic=090204-greg-roberts-02.jpg&cap=Master+satellite+spotter%2C+Greg+Roberts+of+Cape+Town%2C+South+Africa..
Greg's most recent visual satellite observing activities are reported on Space.com at http://www.space.com/businesstechnology/090204-tw-satellite-sleuthing.html. But first, some background -- recent news reports (like this report http://www.satnews.com/cgi-bin/story.cgi?number=252590162) tell of the DoD's secret satellite DSP-F23 wandering out of control in Geostationary orbit . The Feb.5 issue of Space.com tells of Greg's optical tracking of DSP-F23 as it flew near the European Astrium-1 constellation. Click here to see this spectacular video clip of the F23 "flyby" produced thru Greg's efforts. http://www.space.com/common/media/video/player.php?videoRef=SP090203_gRoberts&mode= 73 de Tom, K3IO
