After scrub, SpaceX targets early Saturday for NASA cargo launch

Early on Friday morning, within minutes of the opening—and closing—of an instantaneous launch window, SpaceX scrubbed the launch of its Falcon 9 rocket and Cargo Dragon supply mission to the International Space Station.

The company said it made the decision to stand down due to an "electrical issue" on its Of Course I Still Love You droneship, positioned just offshore for the Falcon 9 rocket's first stage to land on. This is the first time SpaceX has stood down a launch attempt due to a problem related to recovering a first-stage booster. The company can probably thank NASA for being an understanding customer.

After the scrub, SpaceX also said there was a ground-based helium leak it wanted to check out before the rocket's next launch attempt. This leak was located in a "quick-disconnect" interface on the rocket's second stage, where helium is used to pressurize fuel tanks.
