SpaceX installed time-sensitive cargo into the pressurized cabin of a Dragon resupply capsule Sunday in the final hours before liftoff with nearly 2.5 tons of experiments and a critical docking system to welcome piloted commercial spaceships to the International Space Station.
Using a pristine, climate-controlled access port, SpaceX technicians added the “late load” cargo into the Dragon spacecraft while the Falcon 9 rocket sat horizontally at Cape Canaveral’s Complex 40 launch pad.
The ground crew then erected the 213-foot-tall (65-meter) Falcon 9 rocket vertical at Cape Canaveral’s Complex 40 launch pad just after 6 p.m. EDT (2200 GMT) for final preflight checks and fueling.
The Dragon spacecraft perched on top of the slender, two-stage rocket is crammed with nearly 5,000 pounds of supplies. The spaceship will take a two-day trip to the space station, and the research lab’s robotic arm will grapple the approaching Dragon capsule around 7 a.m. EDT (1100 GMT) Wednesday.
The equipment loaded inside the Dragon’s internal compartment includes experiments aimed at demonstrating the feasibility of DNA sequencing in orbit, studying the heart’s response to microgravity, and investigating how to better protect computers from radiation in space.
