The first operational flight of SpaceX’s Crew Dragon spacecraft with four astronauts aboard is set to launch from the Kennedy Space Center in Florida no earlier than Oct. 23, following a formal certification review to assess data from the Crew Dragon’s two-man test flight that concluded earlier this month, NASA said Friday.

NASA astronaut Mark Vande Hei and two Russian cosmonauts will ride a Soyuz ferry ship to the International Space Station early Friday, the first step in a record crew rotation requiring two launches and two landings with four different spacecraft in just three weeks.

NASA’s OSIRIS-REx spacecraft made a touch and go landing on asteroid Bennu at 6:12 p.m. EDT (2212 GMT) Tuesday. The craft aimed to collect samples from the asteroid’s gravely surface for return to Earth in 2023 for scientists to search for clues about the origins and evolution of the solar system.
