CAPE CANAVERAL, Fla. -- An education specialist from Kennedy Space Center prepares to demonstrate the principles of a vacuum chamber to the nationwide attendees of the Tom Joyner Family Reunion. The demonstration was held in front of NASA’s Journey to Tomorrow trailer at reunion headquarters at the Gaylord Palms Resort and Convention Center in Kissimmee, Fla. The reunion was hosted by nationally syndicated radio personality Tom Joyner during the extended Labor Day weekend Sept. 1-4. Besides offering attendees the opportunity to visit tourist attractions in the Orlando area, the reunion gave NASA an avenue to tout the benefits of math and scientific learning, as well as the many educational opportunities offered by the space agency.
