[SatNews] The system appears to be designed to place a kinetic kill vehicle on a trajectory to deep space that could reach medium Earth orbit (MEO), highly elliptical orbit (HEO), and geostationary Earth orbit (GEO).

On Thursday, April 24, at 11 AM EDT, SWF Technical Advisor Brian Weeden will be giving a webinar on his recent report on China's anti-satellite (ASAT) testing in space. The webinar is part of the Union of Concerned Scientists' Global Security Technical Webinar Series. Entitled Webinar: "An Open Source Analysis of China's Anti-satellite Testing in Outer Space", on Thursday, April 24 , 11 AM  EDT (16:00 UTC).

In this webinar, Brian will discuss the open source analysis he recently published on a May 2013 launch from Xichang Satellite Launch Center. This analysis, which included commercial satellite imagery purchased from DigitalGlobe, strongly suggests that the launch was a test of the rocket component of a new direct ascent ASAT weapons system derived from a road-mobile ballistic missile. The system appears to be designed to place a kinetic kill vehicle on a trajectory to deep space that could reach medium earth orbit (MEO), highly elliptical orbit (HEO), and geostationary Earth orbit (GEO). If true, this would represent a significant development in China’s ASAT capabilities. Brian’s recent paper is located at.
