Russia and the PRC can start war in space. What happens if they knock down satellites
If satellites are attacked, it can lead to a failure of land systems GPS, banking systems, power grids, communication of rapid response services, armed forces, etc. According to Lieutenant General, the Chief of Staff of US Space Forces Nina Armmano, the war, resolved in space, will be very noticeable on Earth.
She believes that satellite attacks will be able to disable the communication network in two ways: with a direct attack or through collisions with debris formed from the destroyed satellites. Armano explained that the US military was tracking 600 debris that arose in 2007, when the PRC was failed by one of its own satellites. It takes very little to damage spacecraft like an international space station or satellite. Even the smallest space debris can help.
Armano said the US and allies, including Australia, should cooperate to make space more resistant to any possible attacks. For example, she suggested that you can develop smaller satellites that can move faster than available devices. In addition, the new generation companions will have to avoid not only debris but also attacks. Australia Air Aviation Commander Nicolas Gogan added that Australia, the USA and Canada will work together in this direction.
