BEIJING (CNSA PR) — On the morning of December 19, the National Space Administration held a lunar sample handover ceremony for the lunar exploration project Chang’e 5 mission in Beijing. Together with some participating units, they witnessed the handover of the samples to the mission ground application system, marking that the Chang’e 5 mission was completed The implementation phase has officially shifted to a new stage of scientific research, which kicked off our country’s first extraterrestrial celestial body sample storage, analysis and research work.
BEIJING (CNSA PR) — At 1:59 on December 17, Beijing time, the lunar exploration project Chang’e-5 returner successfully landed in the planned area of Siziwang Banner, Inner Mongolia, marking the successful completion of our country’s first extraterrestrial celestial body sampling and return mission.
HONG KONG, 8 December 2020 (PolyU PR) — In support of the Nation’s first lunar sample return mission, a research team at The Hong Kong Polytechnic University (PolyU) developed and manufactured one of the key systems for this historic undertaking, namely the “Surface Sampling and Packing System”, in collaboration with the China Academy of Space Technology.
The PolyU-developed system accomplished the tasks of automatic sample collection and packaging on the lunar surface following the soft landing of the Chang’e 5 probe on 1 December 2020. The vehicle carrying the samples is currently on course back to Earth, and is expected to touch down in China’s Inner Mongolia region next week.

According to Gao Lei(CNSA official), the orbiter-returner will orbit the Moon for about six to seven days, then enter the Earth-Moon transfer orbit, and experience another three to four days of flight before returning to Earth”. For the rendezvous and docking operations Chang’e-5 used a microwave radar. After docking, the lunar samples were transferred from the ascender to the sample return vehicle.

Chang’e-5’s ascender has lifted off from the moon on its way to an rendezvous with an orbital vehicle that will transport its lunar soil samples back to Earth.
Chinese media are reporting the ascender successfully reached orbit after lifting off from the Ocean of Storms. It is expected to rendezvous and dock with the orbiter-return vehicle on Saturday.
The ascender will transfer its samples to the return vehicle, which is scheduled to land under parachute in China’s Inner Mongolia on Dec. 16.
Chang’e-5’s lander collected soil from the surface using a drill and a robotic arm with a scoop. The goal was to collect at least 2 kg (4.4 lb) of soil.
If successful, China will become only the third nation to return samples from the moon after the United States and the Soviet Union.
Chang’e-5’s liftoff was the first from the lunar surface since the Soviet Union’s Luna 24 mission in 1976. And it was the first vehicle to enter lunar orbit after lifting off from the surface since the U.S. Apollo 17 manned mission in December 1972.
After landing on the moon’s Ocean of Storms on Tuesday, China’s Chang’e-5 lander got right to work collecting soil samples that will be returned to Earth.
The China National Space Administration (CNSA) reports that lander drilled into the lunar surface, extracted a sample, and sealed it up in a container. Chinese media report the hole was 2 meters (6.5 ft) deep.
Chang’e-5 will also collect samples using a robotic arm and scoop. The lander is expected to collect 2 kg (4.4 lb) of soil.
Once sample collection is completed, an ascender will lift off from the moon for a rendezvous and docking with the Chang’e-5 spacecraft in lunar orbit. Launch from the lunar surface could come on Thursday.
The soil samples will be transferred to a sample return vehicle which will travel back to Earth for a parachute landing in China some time in mid-December.
If successful, China will become only the third nation after the United States and the Soviet Union to return samples from the lunar surface.
BEIJING (CNSA PR) — At 23:11 on December 1, the Chang’e-5 probe successfully landed on the pre-selected landing area on the nearside of the moon at 51.8 degrees west longitude and 43.1 degrees north latitude, and returned the landing image.
At 22:57 on December 1, the combination of Chang’e-5 lander and ascender began to perform a power drop from about 15 kilometers away from the moon surface. The 7,500 N variable thrust engine was turned on, and the relative speed of the probe relative to the moon was gradually increased from about 1.7 km/sec.
During this period, the probe made rapid attitude adjustments and gradually approached the moon surface. After that, automatic obstacle detection was carried out. After the landing site was selected, the obstacle avoidance and slow vertical descent began, and the land steadily landed in the area north of the Rumker Mountain in the Ocean of Storms. During the landing, the landing camera equipped with the lander took an image of the landing area.
After the successful landing, the lander under ground control has carried out inspection and setup work, such as the deployment of the solar wing and the directional antenna, and will officially start the lunar surface work lasting about 2 days to collect lunar samples.
BEIJING (CNSA PR) — On November 30, the flight control team of the Chang’e-5 mission of the lunar exploration project implemented the separation of the lander and ascender assembly of the Chang’e-5 probe from the orbiter and returner assembly as planned. At 4:40 in the morning, under the precise control of scientific and technical personnel, the Chang’e-5 detector assembly separated smoothly.
Up to now, the detector systems are in good condition, and the ground measurement and control communication is normal. The orbiter and returner assembly will continue to fly on the lunar orbit with an average altitude of about 200 kilometers and wait for the ascender to rendezvous and dock, and the lander and ascender assembly.
The opportunity will be chosen to implement a soft landing on the lunar surface, and follow-up work such as automatic sampling.
BEIJING (CNSA PR) — At 20:58 on November 28, Beijing time, the Chang’e-5 probe flew to the moon for about 112 hours and successfully ignited a 3000 N engine at a distance of about 400 kilometers from the lunar surface. About 17 minutes later, the engine shut down normally. According to real-time telemetry data monitoring and judgment, the Chang’e-5 probe braked normally in the recent month and entered the orbit around the moon smoothly.
Near-moon braking is one of the key orbital controls during the flight of the lunar probe. When the high-speed probe approaches the moon, it will apply “brake” braking, in order to make its relative speed lower than the moon’s escape speed, and thus be captured by the moon’s gravity.
The Chang’e-5 probe underwent two orbit corrections during the Earth-Moon transfer process and achieved the expected goal. In the future, the Chang’e-5 probe will adjust the height and inclination of the orbit around the moon, the lander and ascender assembly will be separated from the orbiter and returner assembly, implement the lunar frontal soft landing, and carry out the lunar surface automatic sampling as planned. .
WASHINGTON (Frank Lucas PR) — Today, House Science, Space, and Technology Committee Ranking Member Frank Lucas emphasized the risk the Chinese Communist Party (CCP) poses to American international leadership in science and technology following the launch of the CCP’s Chang’e-5 mission to the Moon.
“The launch of Chang’e-5 is a significant step by China towards their goal of establishing a long-term presence on the Moon. The nation that leads in space will dictate the rules of the road for future technological development and exploration, and the influence of the People’s Liberation Army (PLA) in the CCP’s space program makes China a particularly irresponsible and dangerous candidate. Advancements by the CCP also jeopardize American international competitiveness in science and technology. We can no longer take America’s leadership in space for granted and must continue supporting the men and women of the American space program aspiring to launch crewed missions to the Moon, Mars, and beyond.”
BEIJING (CNSA PR) — At 4:30 on November 24th, China used the Long March 5 carrier rocket to successfully launch the lunar exploration project Chang’e-5 probe at the Wenchang Space Launch Site in China.
After the rocket flew for about 2,200 seconds, the probe was successfully sent into the scheduled trajectory, starting China’s first return journey from sampling of extraterrestrial objects.
In a crucial step forward for China’s human and robotic spaceflight programs, a Long March 5B booster conducted its maiden flight on Tuesday carrying a prototype of the nation’s next-generation crewed spacecraft.
China’s most powerful rocket lifted off at 1000 GMT (6 p.m. local time) from the Wenchang Satellite Launch Center on Hainan Island. Chinese media have reported the launch from the nation’s southern spaceport was successful.
BEIJING, February 7, 2020 (CASC PR) — Only one month after the successful launch of the Long March 5 and Long March 3 rockets, another member of the Long March 5 rocket family, developed by China Aerospace Science and Technology Corporation (CASC), started its first journey.
