China is first country to execute robotic docking in lunar orbit

Controllers on Earth had to deal with distance and time lag while precisely maneuvering a clamp into position with almost no room for error. China becomes first country to execute robotic docking in lunar orbit

A Chinese probe was orbiting the moon on Monday in preparation for the returning of samples of the lunar surface to Earth for the first time in almost 45 years. In this video from China’s space agency, the Chang’e 5 sample return mission ascent vehicle — with a crescent Earth behind it — approaches a return craft in orbit around the moon.Chang’e 5 completed the first robotic docking in lunar orbit Saturday.— Spaceflight Now (@SpaceflightNow) December 6, 2020

The orbiter and reentry vehicle will circle the moon for another week awaiting a narrow time window to make the roughly three-day, 238,000-mile journey back to Earth. China is also expected to share some part of them with other countries, as was done with the hundreds of pounds of rocks, sand, dust and other samples obtained by the U.S. Along with being a propaganda coup for the ruling Communist Party, the dual stories illustrate the vast economic and technological advances China has made since it became just the third country in history to launch a person into space in 2003.Chinese foreign ministry spokesperson Hua Chunying praised the “courage to explore, overcome difficulties and pay hard efforts” of those who made the mission possible.”The entirety of the Chinese people are proud of the efforts and wisdom of the Chinese lunar exploration researchers,” Hua told reporters Monday at a daily briefing. It will first “bounce” off the Earth’s atmosphere to slow its speed before the reentry vehicle separates and floats down on parachutes to land on the vast steppes of Inner Mongolia, where China’s Shenzhou crewed spaceships have also made their landings. The accomplishment made China the first country to execute a robotic docking in lunar orbit. opposition has prevented China’s secretive, military-backed program from participating in the International Space Station, although the CNSA has been expanding its ties with other programs, including the European Space Agency, which has helped guide Chang’e 5 on its mission.Last week, Thomas Zurbuchen, NASA’s science director, tweeted a congratulatory message to China after the spacecraft landed on the moon.Chang’e 5 touched down December 1 on the Sea of Storms on the moon’s near side, close to a formation called the Mons Rumker, an area believed to have been the site of ancient volcanic activity.

That marked the first time China had succeeded in lifting off a spacecraft from a celestial body, while no country had previously achieved the tricky feat of executing a robotic docking in lunar orbit. They will be the first fresh samples of the lunar surface obtained by scientists since the Soviet Union’s Luna 24 probe in 1976. The rocks and other debris were obtained both by drilling into the moon’s crust and by scooping directly off the surface. 6, 2020.

If the mission succeeds, it will make China the third country after the United States and former Soviet Union to bring moon rocks to Earth. This graphic simulation image provided by China National Space Administration shows the orbiter and returner combination of China’s Chang’e-5 probe after its separation from the ascender, at the Beijing Aerospace Control Center (BACC) in Beijing Sunday, Dec. The Chang’e 5 ascent stage blasted off from the moon’s surface on Friday, leaving behind the lander module flying the Chinese flag, according to the China National Space Agency.

By way of cautious incremental steps, China is now in the midst of a series of ambitious missions that include a probe en route to Mars and the development of a reusable space plane about which little information has been provided.

Future plans call for returning a human to the moon five decades after American astronauts, along with a possible permanent moon base, although no timeline has been offered. First published on December 7, 2020 / 8:34 AM The ascent module of the Chang’e 5 spacecraft transferred a container with 4.4 pounds of samples after docking with the robot spacecraft on Sunday and was then cut free. The agency also released a photo taken by the orbiter showing it approaching for its rendezvous with the ascender, a sliver of the Earth seen in the background. Chang’e 5 is the first of two planned sample return missions and China’s most ambitious moon mission to date.Bill Harwood contributed to this report.
