A SpaceX Dragon supply ship arrived at the International Space Station Saturday carrying a new docking mechanism, a spacesuit for future spacewalks, and a 3D bioprinter to test the feasibility of manufacturing human tissue in microgravity, according to Spaceflight Now report.

The Dragon spacecraft delivered 2,312 kilograms of supplies, equipment and research investigations for the station’s six-person Expedition 60 crew, the report said.

“I want to congratulate the team across the globe that makes delivering a vehicle like this — it’s pretty looking at it out the window — to the station with science and cargo and things to keep us busy, so the mission continues,” Hague said in a transmission to mission control.

Ground controllers took command of the robotic arm later Saturday to maneuver the Dragon spacecraft to a berthing port on the space station’s Harmony module, where 16 bolts drove closed to firmly connect the cargo ship to the orbiting research outpost.

The station planned to open hatches Sunday leading into the newly-arrived cargo freighter to begin unpacking the ship’s pressurized compartment.

The Dragon spacecraft arrived at its destination Saturday is on its third mission to the space station, following previous trips into orbit in 2015 and 2017.

It’s the first time SpaceX has flown a Dragon capsule three times.
