Along with the joint team that will launch the United Launch Alliance (ULA) Atlas V rocket and Boeing’s CST-100 Starliner in Boeing’s Orbital Flight Test, NASA astronaut Michael Fincke participated in a successful Integrated Crew Exercise on Feb. 12. NASA, ULA, Boeing and Department of Defense personnel executed a mock countdown that practiced fueling the rocket and operating on the unique launch day timeline that features a four-hour built-in hold at the T-minus 4 minute mark. Fincke will fly on Boeing’s Crew Flight Test (CFT), scheduled to launch no earlier than August 2019. OFT and CFT are Boeing’s uncrewed and crewed flight tests of Starliner and part of NASA’s Commercial Crew Program, which will return human spaceflight launches into low-Earth orbit from U.S. soil.
