STS-118 to regulate, monitor, and shut them down in case of trouble; the new system extends and improves the monitoring capability for increased safety.) "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. McAuliffe was killed in the space shuttle "Challenger" accident on 28 January 1986. While McAuliffe and Morgan were classified as spaceflight participants and

The "Collaborative Asteroid Lightcurve Link" assumes an albedo of 0.18 and derives a diameter of 1.99 kilometers, based on an absolute magnitude of 16.068, a figure previously obtained by the Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, and later revised by Czech astronomer Petr Pravec. Between 1998 and 2016, a several rotational lightcurves of "McAuliffe" have been obtained from photometric observations taken by astronomers Petr Pravec at Ondřejov Observatory, Czech Republic, by Andreas Howell at Willowcroft Observatory, Florida, as well
