All systems are go for a close encounter with one of the smallest yet
most active comets known. And it will be happening coincident with Dr.
James L. Green's presentation. He is director of the Planetary Science
Division at NASA Headquarters in Washington D.C. NASA's Deep
Impact spacecraft is hurtling toward Comet Hartley 2 for a breathtaking
700-kilometer flyby Nov. 4. This will be only the fifth time a spacecraft
has flown close enough to a comet to snap pictures of its nucleus. Dr.
Green will explain how significant this flyby is. He started his NASA
career at Marshall Space Flight Center in Huntsville, Ala. Thereafter he
was named to positions of escalating responsibility as he led NASA's
National Space Science Data Center, Space Science Data Operations
Office, Science Proposal Support Office and, in 2006, assumed his
current role.

About TEDx, x = independently organized event
In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
