It carried approximately 4,100 pounds of NASA cargo, science and technology demonstration samples from the ISS. The spacecraft departed from the ISS at 4.58 a.m., after they used the robotic Canadarm2 to detach Dragon from the Harmony module of the orbiting lab.
After Dragon was released from ISS and its thrusters transported it a safe distance away from the station, SpaceX’s flight controllers in Hawthorne, California, executed a deorbit burn command, blasting Dragon back into Earth’s atmosphere.
The Dragon spacecraft will be taken by ship to Long Beach, California, where some cargo will be removed immediately for return to NASA, and then it will be prepared for a return trip to SpaceX’s test facility in McGregor, Texas, for final processing, according to NASA. NASA said a variety of technological and biological studies had returned with Dragon.
Hardware from the Made in Space Fiber Optics payload, which demonstrated manufacturing fiber optic filaments in a micro-gravity environment.
The investigation pulled fiber optic wire from a heavy metal fluoride glass commonly used to make fiber optic glass.
Research indicates that the fiber pulled in micro-gravity may not crystallize as much, giving it better optical qualities than the silica used in most fiber optic wire.
Results from this investigation could lead to the production of higher-quality fiber optic products both in space and on Earth. Some payload samples were used to study a stress reaction in plants when experiencing reduced oxygen or hypoxia, which occurs for example, during times of soil flooding.
