KENNEDY SPACE CENTER, Fla. – SpaceX is preparing to launch a Dragon spaceship from Florida this weekend making its last supply run to the International Space Station until next year. Space Force weather officers are predicting a 50% chance of good weather and conditions are risky for a rocket booster landing at sea. This will be the first launch of SpaceX’s new and improved cargo Dragon spacecraft, not to be confused with the Crew Dragon spacecraft that has now launched two sets of humans to the ISS. After launch, Dragon will arrive at the ISS Sunday almost 24 hours after it departs Florida’s Space Coast. For all previous 20 deliveries by SpaceX, an astronaut would grab the spacecraft with the space station’s robotic Canadaarm.
