A SpaceX Falcon 9 rocket will launch a Cargo Dragon spacecraft with more than 5,000 of pounds of science and supplies to the International Space Station. The Dragon flying this mission will include a new propulsion system within the vehicle’s trunk that will allow it to perform a boost of the space station’s orbit. This is a milestone in SpaceX’s development of the ISS Deorbit Vehicle, which will help slowly lower the orbit of the space station at the end of its functional life around the 2030/2031 timeframe. Delayed from Aug. 21.
