The Crew-3 mission is also SpaceX’s fifth manned launch mission in the true sense of the word. Although SpaceX’s manned dragon spacecraft can be reused, this time a brand new dragon spacecraft is used, which is named “Endurance” (Endurance). Prior to this, SpaceX has conducted four manned launches including the “Inspiration 4” mission. The “Endurance” is SpaceX’s fourth manned spacecraft and is dedicated to the third spacecraft of the International Space Station. The Crew Dragon spacecraft used before includes the “Endeavour”, “Toughness”, and the Crew Dragon spacecraft C207 used in the Inspiration 4 mission.
The Falcon 9 rocket used by Crew-3, including the first-stage rocket body and fairing, has been used before. The rocket number is Block5 B1067.2, which is the second flight of this first-stage rocket. It has been launched before. Through the CRS-22 cargo dragon spacecraft.
This launch is also the same as usual. About 10 minutes after launch, the Falcon 9 rocket landed smoothly on the “please read the manual” offshore recovery vessel, and once again completed the recovery of the first-level rocket. The separation time of the first and second stage rockets is 2 minutes and 52 seconds.
Before the launch, the four astronauts bid farewell to their families.
Two hours before the launch, the rainfall at the Kennedy Space Center was not small, but fortunately, the weather gradually improved before the launch.
Flight crew and mission summary
The astronauts aboard the Dragon spacecraft include NASA astronaut, mission commander Raja Chari (Raja Chari); pilot Tom Marshburn (Tom Marshburn); and mission expert Kayla Barron (Kayla Barron) ); and ESA Matthias Maurer (Matthias Maurer), who will serve as mission expert. The four will go to the space station for a six-month space mission. Except for mission commander Raja Charri, the other three are all debuts in space.
In the next six months, the four astronauts will conduct multiple spacewalks to maintain the space station and help scientific research in orbit, including fiber optics, soilless planting, and how astronauts’ eyes change in space Wait for the experiment.
The parachute failure of the Crew-2 Dragon spacecraft does not affect the launch
Previously, the Crew-3 mission experienced two postponements including weather and health problems of an astronaut. On the other end of the day, another Dragon spacecraft that returned on Tuesday had a parachute delaying the opening of the parachute, and it was opened about 75 seconds late. Fortunately, all four parachutes were opened. After a detailed inspection, NASA assessed that the failure was not correct. Affecting the mission of Crew-3, only three parachutes can ensure a safe splash and fall when returning home, so the launch proceeded as scheduled.
However, the Russian Aerospace Corporation said on Wednesday that Russia is concerned about the parachute failure of the Dragon spacecraft on the Crew-2 mission and has submitted an application to NASA to understand the cause of the failure of the Crew-2 parachute. Earlier, the United States and Russia have agreed to a cross-flight plan for manned spacecraft. Russian astronauts will take the SpaceX Dragon spacecraft to the International Space Station as soon as 2022.

Matthias Morel is a German materials scientist who has worked for the European Space Agency for more than ten years. He has studied Chinese for many years. He has a Chinese name called “Ma Tian”. Life-saving training at sea. Chinese astronaut Ye Guangfu is in the same group as him. During the launch of Shenzhou 13 and the spacewalk of Chinese astronauts last Sunday, Morrel congratulated Ye Guangfu and Wang Yaping on social media, and said that he would meet everyone in space soon.

Long spacecraft toilet problem has been fixed
As early as September this year, during SpaceX’s first all-civilian space travel “Inspiration 4” mission, the Dragon spacecraft toilet once failed. After the three-day trip, the technicians inspected the spacecraft and found that the pipes in the toilets in the cabin were not sticky, causing urine to leak into the toilets under the weightless environment of space.fanAnd under the floor. Subsequently, the toilet pipe of another Dragon spacecraft on the International Space Station was also found to have the same problem.
NASA had previously worried that the urine spilled from the spacecraft might cause structural damage to the spacecraft cabin and even endanger the flight safety of astronauts. SpaceX technicians said that the results of experiments on the ground showed that the residual urine in the cabin would corrode the aluminum structure of the spacecraft to a certain extent, but it would not bring flying hazards. It is safe to ride the dragon spacecraft. The previous Crew-2 mission Dragon spacecraft did not use the toilet during its return to Earth. The four astronauts put on space diapers and returned, although this would cause discomfort to the astronauts.
In this regard, SpaceX previously stated that it has re-modified the toilet design of the Crew Dragon spacecraft, and Crew-3 and subsequent missions should no longer have the problem of urine leakage from the spacecraft toilet.
The Endurance Dragon spacecraft is expected to complete its docking with the International Space Station at around 8:10 am on November 12th, Beijing time. Previously, NASA commercial manned flight project manager Steve Stitch said that the launch time of the Crew-4 mission is tentatively scheduled for April 15, 2022. (Guilin)
