June 1: A United Launch Alliance Atlas V rocket will launch Boeing's CST-100 Starliner spacecraft on its first crewed flight, with NASA astronauts and former Navy test pilots commander Barry "Butch" Wilmore and pilot Suni Williams. The Crew Test Flight (CFT) to the International Space Station will lift off from Cape Canaveral Space Force Station, Florida. Starliner is still set to fly on its historic first flight with astronauts on June 1, but that could change as the team works through "complicated" issues following a small helium leak.
