A detailed analysis of satellite imagery published Monday provides additional evidence that a Chinese rocket launch in May 2013 billed as a research mission was actually a test of a new anti-satellite weapon based on a road-mobile ballistic missile.

Brian Weeden, a former U.S. Air Force space analyst, published a 47-page analysis on the website of The Space Review, which he said showed that China appears to be testing a kinetic interceptor launched by a new rocket that could reach geostationary orbit about 36,000 km (22,500 miles) above the earth.

"If true, this would represent a significant development in China's anti-satellite (ASAT) capabilities," wrote Weeden, now a technical adviser for Secure World Foundation, a Colorado-based nonprofit focused on secure and peaceful uses of outer space.
