Peter Jenniskens (SETI) poses with a fragment of 2008 TC3 collected in Sudan. His talk was about the coolest at the whole meeting. This was the several-meter 'asteroid' detected to be coming straight toward Earth, about 12 hours before impact. This is the first time such a discovery has ever been made. He headed to Sudan soon after the fall, and with the help of Sudanese students, eventually recovered many many fragments scattered across the desert.
