The New Shepard spacecraft blasted off at 8:59 a.m. CDT , and the crew capsule separated from the six-story-tall rocket a short time later as it soared to an altitude of 66 miles .
The flight came two days after it was initially scheduled, with poor weather conditions forcing the mission to be postponed on Tuesday. "Saturday Night Live" comic Pete Davidson had been confirmed as a non-paying promotional guest on the latest flight. But he dropped out earlier this month when the planned launch was postponed from its original March 23 date to allow time for additional pre-flight tests.
