STS-128 (ISS assembly flight 17A) was a NASA Space Shuttle mission to the International Space Station (ISS) that launched on August 28, 2009. Space Shuttle Discovery carried the Multi-Purpose Logistics Module Leonardo as its primary payload. It was Discovery's 37th flight. Leonardo contained a collection of experiments for studying the physics and chemistry of microgravity. Three spacewalks were carried out during the mission, which removed and replaced a materials processing experiment outside ESA's Columbus module, and returned an empty ammonia tank assembly.[4]
The mission's first launch attempt was delayed due to weather concerns, including multiple weather violations in NASA's launch rules, beginning over two hours before the scheduled launch.[5][6][7] The second launch attempt, scheduled for August 26, 2009, at 01:10:22 EDT, was called off the previous evening due to an anomaly in one of the orbiter's fuel valves.[8][9][10] The launch finally took place on August 28, 2009, at 23:59 EDT. Discovery landed on September 11, 2009, at Edwards Air Force Base, which was the last landing of a shuttle to occur at the California site.
