Preparing For Satellite Defense 118

Taco Cowboy sends a report into China's development of anti-satellite technology, and efforts by the U.S. and Japan to build defenses for this new potential battleground. Last year, China launched what they said was a science space mission, but they did so at night and with a truck-based launch system, which are not generally used for science projects. Experts believe this was actually a missile test for targets in geostationary orbit. U.S. and Japanese analysts say China has the most aggressive satellite attack program in the world. It has staged at least six ASAT missile tests over the past nine years, including the destruction of a defunct Chinese weather satellite in 2007. ... Besides testing missiles that can intercept and destroy satellites, the Chinese have developed jamming techniques to disrupt satellite communications. In addition, ... the Chinese have studied ground-based lasers that could take down a satellite's solar panels, and satellites equipped with grappling arms that could co-orbit and then disable expensive U.S. hardware. To defend themselves against China, the U.S. and Japan are in the early stages of integrating their space programs as part of negotiations to update their defense policy guidelines. ... Both countries have sunk billions of dollars into a sophisticated missile defense system that relies in part on data from U.S. spy satellites. That's why strategists working for China's People's Liberation Army have published numerous articles in defense journals about the strategic value of chipping away at U.S. domination in space.

    Most military assets are not in geostationary orbit. You get a better view from closer up, and you move around to cover more area.

    Geostationary orbit is mostly for communications.

    I think the new part here was being able to reach targets in geostationary orbits. We've long had the ability to take out the orbits closer to earth, but geostationary is typically 22,000+ miles out. I'm not sure if our weapons yet have the capability to reach those satellites.

    The route that they are going, is NOT defensive. It is OFFENSIVE. Look, lets say that the west decides to launch against China. By the time that China realizes this, the ICBMs are on their way and have already switched off from sats and are working with intertia systems.

    Where anti-sat systems come into play, from a military pov, is knocking out the enemies eyes and communications PRIOR to your launching first strike.
    China is busy developing a first strike set-up, that is useless for defense.

    In addition, it is now known by the general public that China has active nuclear work going on. They can claim only 300 warheads, but, why hide a nuke facility underground and by a lake then? There was no reason for it, UNLESS you are up to things that get around treaties.
