(20 Dec. 1985) --- Members of the STS-51L crew designed this patch which will represent their participation on NASA's late January 1986 mission aboard the space shuttle Challenger, depicted launching from Florida and soaring into space to carry out a variety of goals. Among the prescribed duties of the five astronauts and two payload specialists will be observation and photography of Halley's Comet, backdropped against the United States flag in the insignia. Surnames of the crew members encircle the scene, with the payload specialists being recognized below. Surname of the first teacher in space, Sharon Christa McAuliffe, is followed by a symbolic apple. Gregory Jarvis, representing Hughes, is the industrial payload specialist for the flight. NASA's crew members are astronauts Francis R. (Dick) Scobee, commander; Michael J. Smith, pilot; and Ronald E. McNair, Ellison S. Onizuka and Judith A. Resnik - all mission specialists.     The NASA insignia design for space shuttle flights is reserved for use by the astronauts and for other official use as the NASA Administrator may authorize. Public availability has been approved only in the forms of illustrations by the various news media. When and if there is any change in this policy, which is not anticipated, the change will be publicly announced.
