"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.

The body's observation arc begins at Heidelberg in February 1924, two days after its official discovery observation. In the Tholen classification, "Christa" is a common C-type asteroid, while in the SMASS classification, it is a Xc-subtype that transitions from the carbonaceous C-type to the X-type asteroids. It has also been characterized as a primitive P-type asteroid by the Wide-field Infrared Survey Explorer (WISE). In April 2005, a first rotational lightcurve of "Christa" was obtained from photometric observations by French
