Yes, they are aware. Russia wanted to demonstrated that they can blow satellite from the ground - from the military perspective this is important as they can blind to some extent NATO (or Chinese) battle control systems.
This is demonstration of their force, which in reality is not that great, but Russia is a master in the game of pretending that they are immensely powerful. This gives them a lot of political benefits and leverage. This is kind of action as grouping troops on the Ukrainian border or flooding Polish-Belarusian border with migrants, etc.
