STS-118 Mission Specialist Barbara R. Morgan is helped with her helmet for launch aboard Space Shuttle Endeavour.

In the Operations and Checkout Building during suitup, STS-118 Mission Specialist Barbara R. Morgan, teacher-turned-astronaut, is helped with her helmet for launch aboard Space Shuttle Endeavour. The STS-118 mission is the 22nd shuttle flight to the International Space Station. It will continue space station construction by delivering a third starboard truss segment, S5, and other payloads such as the SPACEHAB module and the external stowage platform 3. The 11-day mission may be extended to as many as 14 depending on the test of the Station-to-Shuttle Power Transfer System that will allow the docked shuttle to draw electrical power from the station and extend its visits to the orbiting lab.
