The moment of chang'e-5 landing: Jade Rabbit grabs the mirror to sample and return successfully

Good news in the morning! At 1:59, the lunar exploration project chang'e-5, carrying lunar samples, landed at Siziwang Banner landing site in central Inner Mongolia, marking the successful completion of China's first mission of sampling and returning extraterrestrial objects.

At about 1:00 a.m., Beijing aerospace flight control center injected high-precision navigation parameters into the chang'e-5 orbiter and reentry vehicle combination through the ground TT & C station. After that, the orbiter and the reentrant are usually unlocked and separated from the South Atlantic sea level at an altitude of about 5000 km, and then the orbiter completes the evasion as planned.

At 1:33 a.m., chang'e-5 entered the earth's atmosphere at a speed close to the second universe speed (about 11.2 kilometers per second), about 120 kilometers above the ground, and performed the first aerodynamic deceleration. After falling to a predetermined height, the retractor jumps out of the atmosphere and begins to slide downward after reaching the highest point. After that, the reentrant enters the atmosphere again and performs a second aerodynamic deceleration. When it descends to a height of about 10 km above the ground, the retractor opens the parachute to complete the final deceleration and maintain a stable attitude, and then lands smoothly in the predetermined area. The technicians who are responsible for the measurement, control and recovery of the search and recovery tasks will find the targets in time and carry out the recovery work in an orderly manner.

On December 3, the lifter ignited and took off and entered the orbit precisely. The rendezvous, docking and sample transfer with the orbiter and the reentrant assembly were completed on December 6. After that, separation and controlled lunar landing were carried out as planned. From December 12 to 16, the combination of the orbiter and the reentry vehicle separated from the orbiter and returned to earth on December 17 after completing two monthly earth transfer incident and two orbit corrections.

According to the plan, the recovered chang'e-5 reentrant will be airlifted to Beijing to open the cabin after completing the necessary ground treatment work, and take out the sample container and cargo. The National Space Administration will hold a handover ceremony at the right time and formally hand over the lunar samples to the ground application system. The first work related to the storage, analysis and research of extraterrestrial objects in China will also be started.
