Planetary Defense Conference

One thing that could a stop the Singularity (and most life on the planet) would be a large asteroid impact (and Apophis will be passing closer than the orbit of weather satellites in 2029 - with a possible impact in 2036). However, Spacedaily reports on the agenda for an upcoming Planetary Defence Conference. From the article:

A session on "Deflection Techniques," chaired by Dr. David K. Lynch of The Aerospace Corporation, and a session on "Deflection Missions and Technology," chaired by Dr. Gianmarco Radice of the University of Glasgow, will be held on March 6. These two sessions will explore explosive and non-explosive techniques for deflecting a threatening object and issues associated with executing a mission, including the central question: "Can we get there with today's technology?"
