Sir Isaac Newton's birthday. Without his work on gravity, we might not have satellites. 73s Bernhard VA6BMJ @ DO33FL

Apollo 8 reaches the moon and makes 10 orbits, demonstrating that a lunar landing might be feasible. It was the first time that a crew flew further than LEO and entered the gravitational field of another celestial body. 73s Bernhard VA6BMJ @ DO33FL

PCSAT recovery attempt
by Bob Bruninga 24 Dec '11

24 Dec '11

Starting Monday Morning, I will be trying to recover PCSAT. We need everyone to not use it until we give up. Just one single packet from a user during a pass will easily kill that pass's chance of recovery.. We only get one single packet chance per pass for recovery. So everyone. Turn off those automatic beacons via PCSAT until further notice. Thanks Bob, WB4APR

RS-15 launch cover for anti-satellite test?
by Armando Mercado 24 Dec '11

24 Dec '11

Greetings, This may be old news to some, but I came across an interesting article about a Soviet era anti-satellite test program called Naryad. It made a couple of sub-orbital test flights, and then supposedly was launched into a high orbit along with RS-15 on December 26, 1994. RS-15 was deployed and a short time later the booster stage turned into many objects. (Object 94 085 B-V.) http://www.russianspaceweb.com/naryad.html Interesting story atleast. 73, Armando N8IGJ
