STS088-703-019 (4-15 DECEMBER 1998) --- The U.S.-built Unity connecting module (bottom) and the Russian-built Zarya module are backdropped against the blackness of space in this 70mm photograph taken from the Space Shuttle Endeavour. After devoting the major portion of its mission time to various tasks to ready the two docked modules for their International Space Station (ISS) roles, the six-member STS-88 crew released the tandem and performed a fly-around survey of the hardware.
