Designed by the mission crew members, the STS-66 emblem depicts the Space Shuttle Atlantis launching into Earth orbit to study global environmental change. The payload for the Atmospheric Laboratory for Applications and Science (ATLAS-3) and complementary experiments were part of a continuing study of the atmosphere and the Sun's influence on it. The Space Shuttle is trailed by gold plumes representing the astronaut symbol and is superimposed over Earth, much of which is visible from the flight's high inclination orbit. Sensitive instruments aboard the ATLAS pallet in the Shuttle payload bay and on the free-flying Cryogenic Infrared Spectrometers and Telescopes for the Atmospheric-Shuttle Pallet Satellite (CHRISTA-SPAS) that gazed down on Earth and toward the Sun, are illustrated by the stylized sunrise and visible spectrum.
