The SpaceX Dragon ship arrived on December 17 to the ISS, delivering food and experiments for astronauts in orbit. Management reported a successful docking after the sealing process was completed for all 16 bolts. At that time, the crew flew at a height of 250 miles above the North Atlantic. Docking produced with the help of a robotic arm.
The re-launch ship was launched on Friday. With his help, 2200 kg of food, supplies and experiments were delivered, among which one is devoted to the study of thyroid cancer, and the second is the cultivation of barley in space.
In the picture, the robotic arm pulls and captures the Dragon spacecraft to dock with the ISS on December 17. SpaceX sent the ship from Cape Canaveral (Florida) on December 15, using the Falcon re-launch rocket. It was the first launch of a reusable rocket with a reusable capsule. For the first time, SpaceX successfully launched a rocket and a cargo ship, both of which belong to the reusable program. The company, led by Ilon Mask, aims to reduce the cost of a space flight by reusing expensive rocket units.
It was the 14th successful return this year. Earlier, Dragon flew to the ISS in 2015. NASA is the most important client for SpaceX.
