The B612 Foundation was established in 2002. In our first ten years as a volunteer organization, our focus was on asteroid deflection research and advocacy. The team developed several deflection concepts, ones that are accepted today as standard techniques to prevent an impact. The following blog posts were issued/posted prior to the B612  Foundation’s decision to build, launch and operate the Sentinel Space Telescope, which was announced in June 2012.
