Video: When the Soviet Union fired a Space Cannon in Orbit

(005875.811-:E-000062.43:N-AC:R-SU:C-30:V)   

[This gives some interesting background. It never occurred to me that the Soviets has 9 Salyuts, of which 6 made it into orbit. So they were pretty small space stations it seems. The addition of the cannon is interesting. Destroying or damaging satellites in space will be something that can happen in future, important wars. Jan]
