James Webb Space Telescope
In June 2010, Hammel participated in the World Science Festival held in New York City, by the James Webb Space Telescope model in Battery Park. Hammel talked about the discoveries anticipated in 2014 with the launching of the James Webb Space Telescope, which will be the world's most powerful space telescope, being the successor to the Hubble Space Telescope. Other speakers included John C. Mather, a Nobel laureate and the Webb telescope's senior project scientist and Dr. John Grunsfeld, astronaut, physicist and "chief repairman" of the Hubble Telescope.
