The US and China now have a 'space hotline' to avoid satellite warfare

Washington and Beijing are making efforts to avoid a crisis in space before it happens. The US and China have set up a direct link — or "hotline" — allowing both nations to easily share information about activities in space. Specifically, the so-called space hotline is designed to help the space and military agencies of both countries to discuss "potential collisions, approaches, or tests," according to the Financial Times.
Like the well-known "red telephone," set up between Moscow and Washington in the aftermath of the Cuban Missile Crisis, the idea is to keep a misunderstanding or other miscommunication from escalating to a dangerous situation in space and here on Earth.
