Now that SpaceX has completed Crew Dragon’s in-flight launch escape test, when can you expect a mission with humans aboard? At last, the company has a more specific answer than early 2020. Company chief Elon Musk told attendees at a post-test conference that the crewed mission to the International Space Station will likely take place in the second quarter of the year, or sometime between April and June. SpaceX was “highly confident” the hardware would be ready in the first quarter, “most likely” in February.
