Photos: Falcon takes flight

The first official launch weather outlook issued Tuesday by U.S. Air Force meteorologists predicts an 80 percent chance of favorable conditions for the predawn liftoff Saturday of SpaceX’s Crew Dragon spacecraft on a test flight to the International Space Station.

SpaceX’s next launch of satellites for the company’s Starlink broadband network — planned in the final days of 2019 — will carry one spacecraft with an experimental coating designed to make it less reflective in orbit, a first step in assuaging concerns from scientists who say the deployment of thousands more Starlink stations would impede some astronomical observations.

Two more roll-out solar arrays will ride a SpaceX cargo ship to the International Space Station this weekend, continuing a years-long mid-life station upgrade as NASA plans procurement of a final set of new solar wings to fully reinforce the lab’s power supply.
