Successful docking! About 19 hours after SpaceX’s manned spacecraft was launched, at 10:27 p.m. Beijing time on May 31, the spacecraft’s 12 hook-shaped claws grabbed the station’s interface and docked. The two astronauts then made it to the International Space Station. Although expected, but the outside world is still feeling. This historic docking success, created a new page of private commercial space.

Humans have unlocked a new posture for exploring space!
The Dragon spacecraft arrived near the International Space Station at 10:16 p.m. Beijing time on May 31. At this point, about 19 hours before the rocket lifted off.
The Dragon spacecraft took a photo of the International Space Station at a distance of 150 meters from the space station.
A few minutes later, the spacecraft is 60 meters from the space station, and the space station’s perspective is observing the Dragon spacecraft:
Then, a little closer to the space station, the most exciting moment came:
After the successful docking, the two astronauts did a series of routine checks.
About two hours later, at 1:02 a.m. Beijing time on May 31, the astronauts stationed on the International Space Station opened the hatch and two of the Dragon spacecraft entered the International Space Station, shaking hands and hugging the expedition astronauts who welcomed them to The Expedition 63.
The Dragon spacecraft went through five stages before the astronauts entered the International Space Station.
First, the launch and the separation of the second-stage rocket from the spacecraft, the Dragon spacecraft into Earth orbit. The ship has an altitude of 201 kilometers to the ground.
In the second stage, the spacecraft orbits the Earth. During this time, the two astronauts slept in the cabin for about seven hours. At 4:45 p.m. Beijing time on May 31, the astronauts were woken up to perform a docking mission with the International Space Station.
In the third stage, the spacecraft launches the booster to orbit the International Space Station. The International Space Station orbits the Earth at an altitude of about 402 kilometers to earth at a speed of more than 27,000 kilometers per hour.
In the fourth stage, when the spacecraft flies into a straight line with the station,’ it automatically approaches the station at a relative rate of several centimeters per second.
When the spacecraft was about 219 meters from the space station, the astronauts stopped autopilot mode and used manual control stoamish approach to the station. The operation is designed to verify the astronaut’s ability to control the spacecraft. This is one of the most important objectives of this test flight.
Before the spacecraft and the space station are about to dock, the astronauts again turn on automatic flight mode to complete the docking mission.
After docking, the astronauts conducted more than two hours of testing to ensure that the spacecraft’s seams with the space station were fully sealed.
In the fifth stage, Bob and Doug went to the space station. For the first time, the International Space Station has welcomed commercial astronauts in casual clothing to the station.
At docking, the International Space Station was just over China.
Weibo user @CUC photography Tianxuan used a camera and telescope to capture the whole process.
At 20:40 p.m. Beijing time, you can see the clear outline of the International Space Station, and the Dragon spacecraft behind.
By the time the station crossed again at 22:17, the two targets were so close that they could only see the International Space Station.
After docking, the astronauts on the mission will stay on the station for about 30-119 days, during which time they will be able to participate in the station’s ongoing scientific experiments.
NASA and SpaceX said in previous disclosures that they would look at the status of the Dragon spacecraft.
After the return date is set, the Dragon spacecraft will depart from the International Space Station and then fly freely in space for two days to further test the relevant systems and procedures.
The booster is then ignited for 15 minutes, leaving the spacecraft out of orbit and then falling.
After crossing the atmosphere, four parachutes will open at a suitable altitude, slowing down the impact and allowing the Dragon spacecraft to fall about 450 kilometers off the Florida coast at an angle tilted.
After that, the staff, who had been waiting nearby, would help the astronauts get out of the Dragon spacecraft.
The DM-2 mission to make history
This DM-2 mission, if completely successful, also means that SpaceX will achieve all of the following achievements:
1, the dragon spacecraft’s first manned space launch.
2, the first manned space launch on the U.S. mainland since the space shuttle was retired in 2011.
3, the first flight of the new era of global commercial manned spaceflight.
4, the world’s private space companies manned space first flight.
5, the world’s 9th manned spacecraft launched (Soviet Eastern spacecraft, Mercury, The Soviet Union Ascending spacecraft, the United States Gemini spacecraft, the Soviet Soyuz spacecraft, the United States Apollo spacecraft, the United States space shuttle, China’s Shenzhou spacecraft).
6, the United States 5th manned spacecraft launched (Mercury spacecraft, Gemini spacecraft, Apollo spacecraft, space shuttle after).
7, SpaceX’s 94th space launch was successful.
8, the 85th successful space launch of the Falcon 9 rocket.
9, the 52nd successful recovery of rockets.
10, the 33rd successful sea recovery rocket.
The flight was the beginning of SpaceX’s manned spaceflight. NASA plans to use the data collected from the mission, mainly astronauts operating the reliability of the spacecraft manually, and the spacecraft’s life support system, to certify that the manned Dragon spacecraft is eligible for a manned mission to and from the International Space Station on a regular basis.
SpaceX and NASA’s next Dragon mission, Crew-1, are tentatively scheduled for August 30, when the Dragon spacecraft will carry four astronauts to the International Space Station.
Chapter One of Commercial Space
Earlier this year, Musk launched a $55 million tour of the space station, with a $55 million ticket, and someone is said to have booked seats.
This means that the aerospace industry will move further from a pure toG project to a to-C business.
At the same time, China’s commercial space program is moving forward.
On May 27, China’s private rocket company Star Glory’s Focus One (codenamed “JD-1”) successfully completed a second-start 500-second test, the world’s first liquid-oxygen methane engine with secondary start-up capability.
According to official information, “Focus One” (code-named “JD-1”) engine is a 15-ton reusable engine, using clean and environmentally friendly, low-cost, not easy to focus liquid oxygen methane fuel, engine design can be reused 30 times, can save more than 70% of the rocket manufacturing costs.
One more thing
A foreign netizen discovered that Doug Hurley had hit the door of the dragon’s door as it entered the International Space Station through the hatch.
In the video, Hurley can be seen rubbing his hands at the area where he was knocked before greeting others.
Netizens have expressed very distressed, but this should be a slight bump, there will be no major obstacles.
On May 13, SpaceX launched a simulated program for a manned Dragon spacecraft docking to the space station on its official website, allowing you to experience the process of docking a spacecraft to the space station in front of a computer.
