In case someone wants to run a recent Linux kernel on an FC8 box, I have made an RPM for 18.104.22.168 and you can download it here. Should also install on CentOS 5/RHEL 5 if you use --force.
This breathtaking photo was taken next to a space communication facility near Ussuriysk, Russia. The biggest RT-70 radiotelescope has a 70m diameter antenna with an area of 2500 sq. m! The telescope stands over 100m high, can rotate 360 degrees and weights over 24 thousand tons  . Impressive gadget :) Sadly, not used nowadays, due to lack of financing and deep space missions.
