A few hours ago, Boeing’s CST-100 Starliner Calypso spacecraft docked with the International Space Station’s Harmony module, completing the first leg of its Boe-CFT (Boeing Crewed Flight Test) mission which began with the launch just over 24 hours earlier. After checking that the pressure was correctly balanced, the hatch was opened to allow Butch Wilmore and Suni Williams to enter the Station and begin their mission, which will last about a week.
