Beijing time April 11 morning news, SpaceX Friday afternoon successfully launched the planned flight to the International Space Station "Falcon 9" rocket. At 7:23 a.m. ET on Sunday (19:23 GMT), the International Astronaut Station received supplies from Falcon 9. This is the first time SpaceX has successfully completed its mission to the International Space Station after the failure of the last supply mission in June last year. The Falcon 9 rocket carried a Dragon spacecraft and delivered about 7,000 pounds (3175 kg) of supplies. Of these, about 3,000 pounds (about 1361 kg) are "Bigelow Extensible Activity Modules" (BEAM), which will provide 565 cubic feet of space for the International Space Station. Upon arrival at the ISS, BEAM will connect to the ISS Tranquility node and install it within the next 4 months. BEAM plans to spend 2 years at the ISS to help engineers gather data on the use of this module in space environments. "Dragon" spacecraft also carry a series of other scientific experimental materials, such as a pile of cabbage. The space station astronauts will grow and consume these cabbages. The crew cabin also carried 20 live mice from the pharmaceutical company Eli Lilly. This will help researchers better understand the mechanism of muscle wasting. In space environment, muscles shrink more rapidly than normal. In addition, a student-designed trial will test a way to identify the genetic damage that astronauts may encounter in space. The "Dragon" spacecraft is now connected to the ISS and will remain there for the next month, eventually returning to Earth on 11 May. At the appointed time, the "Dragon" spacecraft will carry important materials back to the ground, including the astronaut Scott Kelly's body sample in space. Kelly has been on the ISS for 340 days, helping NASA see how the human body can make changes to the micro-gravity environment over a longer period of time, and these samples will reflect the change. The "Dragon" spacecraft will then land on the Pacific Ocean outside California. In the next eight years, SpaceX will also perform several ISS replenishment tasks. The contract between SpaceX and NASA extends into 2024. Earlier, SpaceX successfully completed 6 replenishment missions, but its seventh mission in June last year failed and the Falcon 9 rockets exploded. In the next six months, SpaceX suspended the rocket launch and started the investigation. The end result showed that the reason for the failure was a problem with one support rod of the higher-level bunker. SpaceX resumed its rocket launch in December last year. Hans Koenigsmann, vice president of mission security at SpaceX, said at the time that the company had upgraded its rocket and adjusted its support system. After the launch of the rocket on Friday, SpaceX also successfully recovered a portion of the Falcon 9 rocket off the offshore platform.
