SpaceX completed Friday the last drop test of the Dragon crew capsule’s parachutes before the first launch of astronauts on the human-rated ship May 27, while technicians at Cape Canaveral have mated the spacecraft’s crew module with its unpressurized trunk section.

The launch of the first batch of new-generation Iridium communications satellites Saturday marked the beginning of the end for the predictable, spectacular flares of reflected sunlight produced by the old-design craft, a favorite of amateur skywatchers for nearly two decades.

Nearly a decade in the making, NASA and SpaceX have set May 27 as the target launch date for the first crewed space mission to launch into orbit from U.S. soil since the retirement of the space shuttle in 2011.
