A SpaceX Dragon supply ship arrived Saturday the International Space Station with a new docking mechanism, a space suit for future spacewalks and a 3D bioprinter to test the feasibility of producing human tissue in zero gravity.  Astronaut Nick Hague, who was in control of the Station's robotic arm built in Canada, reached for the Dragon cargo ship on Saturday at 9:11 am (1311 GMT) as the complex spans 429 kilometers over the coast of the South ascended Chile.
The spacecraft Dragon provided 5 097 pounds (2 312 kilograms) of supplies, equipment and research for the Station's six-man Expedition 60 crew.
"I would like to congratulate the team around the world that can deliver a vehicle. This way – it's nice to look out the window – to the station with science and cargo and things to do with the mission continues, "Hague said in a submission to Mission Control.
Ground controllers commanded the robotic arm later on Saturday to maneuver the kite spaceship to a berth on the space station's Harmony module, where 16 bolts were turned to connect the cargo ship tightly to the orbiting research outpost.  The station planned to open the hatches on Sunday, which led to the newly arrived cargo freighter, to begin unpacking the pressurized compartment of the ship.

The Dragon Spaceship has arrived in space on Saturday for its third space mission the first time that SpaceX has flown three times with a Dragon capsule.
The automated cargo carrier took off on a Falcon 9 rocket from Cape Canaveral on Thursday.
This flight included approximately 5,000 pounds of science, key spare parts, food, and other items, including the International Docking Adapter # 3 (external), "said Bill Spetch, NASA's NAS Space Station Integration Manager a preliminary examination. Start press conference. "We are very much looking forward to putting this into practice and it is an important piece of hardware for the future of the ISS as it creates the conditions for how we will operate commercial vehicles and our partners in the future."
The third international Docking Adapter (IDA-3) Will Accommodate SpaceX and Boeing Commercial Crew Ferry Ships Crew Dragon and Starliner.
IDA-3 was built by Boeing to replace a unit used in a spaceX launch error SpaceX successfully delivered IDA-2 to the station in 2015. The new docking mechanism was first deployed in March by SpaceX's Crew Dragon spacecraft on a non-flown test flight before the official astronauts released the vehicle.
NASA issued in 2016, Boeing will pay $ 9 million to build the replacement docking adapter Spare parts left over from the first two units.
The robot arm of the space station pulls IDA-3 from the non-pressurized rear payload bay of the Dragon cargo pod and places it on the space-facing zenith haven of the Harmony module of the space station in mid-August, so that Boeing's Starliner and SpaceX crew Dragon Park capsules simultaneously with two separate docking adapters on the station.
"While we spin the crews through the vehicle, we want them to have the time to hand over face to face, so it's very important to activate these two docked vehicles," Spetch said.
The new docking mechanisms are designed to attach to the station's docking ports during the Space Shuttle era. The spacecraft crew Dragon and Starliner use a different docking system than the shuttle.
Two astronauts will be leaving the station next month to make the connections between IDA-3 and the Harmony module.
A habitat of 40 female mice that was also launched in the spacecraft Dragon by SpaceX. The capsule will return to Earth from its one-month mission with 20 mice, and samples of the mice will be distributed to medical and biological researchers to study how space impacts muscles, bones, the immune system, and the organs of animals.
The other 20 mice remain on the ward to be more exposed to weightlessness.
NASA also placed a space suit in the printing module of the Dragon Cargo Crafts, which can be used by astronauts on spacewalks.
Here is a breakdown of the cargo aboard the Dragon Spaceship:
- Scientific Investigations: 2628 pounds (1192 kilograms)
- Crew Supplies: 233 kilograms (514 pounds)
- Spacewalking Gear: 179 kg (394 lb)
- ] Vehicle hardware: 345 lb (157 kg)
- Computer Resources: 38 lb (17 kg)
- Unprinted Payloads (IDA-3): 1,177 pounds (534 kilograms)

Goodyear Tire and Rubber Co. also has an experiment on the Dragon Supply Ship. The tire manufacturer will study the formation of silica fillers, a material commonly used in consumer tires in the microgravity environment of Earth orbit.
According to Goodyear, engineers can use the experimental findings to assess possible improvements in the silica construction process and rubber formulation.
"Goodyear pioneered tire innovations in space, with the first and only moon on the moon, numerous projects with NASA, and now this," said Eric Mizner, Goodyear's director of global materials science. in a press release. "It underlines our passion for developing new technologies that help us deliver groundbreaking products with real consumer value."
Space station experiment results could lead to improvements in fuel efficiency and other factors According to Goodyear, tire performance factors exist.
Japanese scientists also sent out an experiment to grow moss in space to compare how the plant grows in space with its behavior on Earth. Moose could be used as a food or oxygen source for future space missions, such as moon or Mars base stations.
The mission is the 18th SpaceX flight to recharge the space station as part of a $ 3.04 billion freight transportation contract with NASA. The contract, first signed in 2008, includes 20 replenishment missions.
SpaceX also has separate billion-dollar contracts for additional shipments in the early 2020s and for the development of the Transport-provided Crew Dragon or Dragon 2 capsule, both cargo and astronauts.
The enhanced Dragon 2 vehicle can dock directly with the space station without relying on the robotic arm to capture it. SpaceX plans to use a cargo variant of the Dragon 2, similar in design to the human-rated Crew Dragon, for next year's replacements, which will lead to the discontinuation of the current Dragon design. Saturday will be the international research complex on 27th. Leave August and head to the Pacific Ocean to return home with research items and another space suit that needs refurbishment.
