"Endeavour" also received several systems that the other orbiters had already been equipped with, such as a glass cockpit, improved wing leading-edge sensors and the OBSS. STS-118 included mission specialist Barbara Morgan, the first Mission Specialist Educator. Morgan trained as the backup to Christa McAuliffe, NASA's Teacher in Space candidate from 1985 to 1986.

Christa McAuliffe (NASA paid both their salaries.) While not a member of the NASA Astronaut Corps, McAuliffe was to be part of the STS-51-L crew, and would conduct experiments and teach lessons from space. Her planned duties included basic science experiments in the fields of chromatography, hydroponics, magnetism, and Newton's laws. She was also planning to conduct two 15-minute classes from space, including a tour of the spacecraft, called "The Ultimate Field Trip", and a lesson about the benefits of space travel, called "Where We've Been, Where We're Going, Why." The lessons were to be broadcast to millions of schoolchildren via closed-circuit
