On the 4.6-million-mile, nearly 12-day STS-88 mission, Endeavour carried the U.S.-built Unity connecting module to begin construction of the International Space Station. The crew successfully mated Unity with the Russian-built Zarya control module during three space walks. With this mission, Ross completed seven space walks totaling 44 hours and 9 minutes, more than any other American space walker. Newman moved into third place for U.S. space walks with a total of 28 hours and 27 minutes on four excursions
