The space exploration technology company spacecraft came back with "specialties". What are the "specialties"?

At the beginning of April this year, materials and equipment were sent to the International Space Station. A space exploration technology company dragon spacecraft has just bid farewell to the International Space Station and returned to Earth, bringing back nearly 2 tons of experimental samples for NASA.

So, what "specialties" did the "Dragon" spacecraft bring back this time?

1. A mouse that has lived on the International Space Station for some time. For human beings, this mouse that has lived in the International Space Station for a period of time has extremely high research value. Scientists hope to study how the bones of mice change under weightlessness. It can also be used to study the health effects of space flight. 2. Robonaut 2 robot of NASA. At that time, the goal of astronaut robot design was to help astronauts in space deal with daily chores. 20 14 is out of order, and NASA will analyze and repair it. Ricky Arnold, a NASA astronaut, put a mask on Robonaut 2' s head and sent some interesting Twitter photos.

3. Other scientific experimental samples include plants, insects and human organs.

These "specialties" brought back include specific scientific samples, which means that human beings have more research materials in the process of exploring space. In addition, there is a very important significance worthy of our attention.

Yes, in the government-led aviation field, Space Exploration Technology Company is an American private space transportation company, which was founded by Tesla founder elon musk in June 2002. In February this year, when the space exploration technology company went to heaven, Musk also attracted the attention of the whole world. His hero said that he didn't know anything about rockets because the company was on the verge of bankruptcy because it couldn't get financing, but he never thought about giving up. He said, "Either die safely or live wonderfully."

These special products brought back by "Dragon Spacecraft" have witnessed the new height of commercial aerospace.
