Since launch, Dragon has been traveling toward the ISS, carrying 6,500 pounds of cargo, science and supplies to help researchers study how the human body changes in space.

On Sunday, at 6:37 a.m. EDT, the SpaceX Dragon spacecraft docked to the forward port of the International Space Station’s Harmony module, carrying nearly 6,500 pounds of food, supplies, and equipment ...

The spacecraft will be docked at the ISS for a month before heading for splashdown with time-sensitive research and cargo.

NASA and SpaceX are targeting a May 12 launch to deliver science, supplies and equipment to the International Space Station.

The docking, which happened high above the northwest Pacific, highlights the remarkable routine of modern space travel that once seemed like pure science fiction.
