“Last year, China launched a mysterious missile from its southwest region. While Chinese news sources said it was a scientific experiment, there is widespread speculation that the payload was a more advanced anti-satellite test. Satellites are vulnerable to an array of weapons and disruptive technologies like anti-satellite missiles and sophisticated cyber attacks that can have potentially devastating results from degrading capabilities to complete annihilation, experts said. There is strong evidence that the anti-satellite weapon China tested in May 2013 went higher than low-Earth orbit, said Charles Miller, president of NextGen Space LLC, a space and public policy consulting group. If China continues to make strides and develops weapons that reach farther, it could one day threaten key satellites in geosynchronous orbit. “
