In November, we reported how an impact on the Moon from a Chinese Long March rocket booster created an unusual double crater. For a single booster to create a double crater, some researchers thought there must have been an additional – perhaps secret – payload on the forward end of the booster, opposite from the rocket engines. But that may not necessarily be the case.
Other researchers feel the extra mass wasn’t anything secretive, but possibly an inert structure such as a payload adapter added to the rocket to support the primary mission payload.

Last year, astronomers warned that a large piece of debris was on a collision course with the Moon. Initially, they speculated that it was a SpaceX booster but later zeroed in on a Chinese Long March 3C rocket booster that launched the Chang’e 5 mission. When it did impact on March 4, 2022, astronomers noted a strange double crater.
A new paper suggests that it couldn’t have been a single object breaking up since there’s no atmosphere on the Moon. Instead, the booster must have been carrying an additional, undisclosed payload.

A Chinese Long March 5B rocket first stage made an uncontrolled, fiery reentry through Earth’s atmosphere over Southeast Asia today (Saturday), six days it launched a new science module to China’s Tiangong space station. While the eventual return of the booster was known, China made the decision to let it fall uncontrolled. They also did not share any tracking data, and the large size of the rocket stage drew concern about fragments possibly causing damage or casualties.
The US Space Command confirmed reentry of the debris from the roughly 30-meter-long core (100 ft.) stage of the Long March 5B occurred at 12:45 p.m. Eastern time (1645 UTC) on July 30, 2022 over the Indian Ocean.

Two Lego designers with a history of space-themed projects have teamed up for a new proposed set: China’s Long March CZ-5 and Tianwen-1 Mission. The set is currently gathering supporters on the LEGO Ideas website. If it gets enough support, LEGO will review it and possibly create it.
Early on Thursday, a Long March 5B rocket – currently the most powerful of China’s space launch vehicles – blasted off from Wenchang, carrying the first major component of an ambitious new modular space station.
The station module, dubbed Tianhe (Harmony of the Heavens), marks the next big step in China’s human spaceflight program in Low Earth Orbit (LEO). Barred from participating in the International Space Station (ISS) by US law, which forbids cooperation in space between the two countries, China has been developing its own LEO capabilities for over a decade now.

China’s proposed next-generation rocket reached the final stage of feasibility studies this month. The planned launch vehicle, known as the Long March-9, will be capable of sending 100 tons to the Moon, and could see its first launch as early as 2030.
Announced in 2018, the Long March-9 will play a key role in China’s long-term space ambitions. If all goes as planned, its first payload is likely to be a Martian sample return mission, and it would support China’s Lunar ambitions as well. Another proposed use for the super-heavy lift vehicle is to build an experimental space-based solar power station, although plans for that project are still very tentative.

In July there’s another launch window to Mars. It looks like China is ready to take advantage of it, by launching their first rover to the planet. It’s called Tianwen-1, meaning “Heavenly Questions”, or “Questions to Heaven.” The complete mission consists of a lander, an orbiter, and a rover.

China’s historic first docking mission in space ended in a complete success today (Nov. 17) following the safe landing of the unmanned Shenzhou-8 in Inner Mongolia. Today’s landing will robustly propel China’s space program forward and sets the stage for an ambitious agenda of human spaceflight missions in 2012 to the Tiangong-1 Space Lab and eventually to a hefty 100 ton Earth orbiting Space Station to be assembled by 2020.
Shenzhou-8 was launched to low Earth orbit on Nov. 1 atop a Long March 2F booster from the Jiuquan Satellite Launch Center in the Gobi Desert and successfully conducted China’s first ever rendezvous and docking mission in space with the nation’s Tiangong-1 Space Lab module on Nov. 3 while orbiting some 343 kilometers in altitude above Earth.
Gen. Chang Wanquan, the Commander in Chief of China’s human spaceflight program said, “The Shenzhou-8 capsule has safely returned to the main landing site at Inner Mongolia and the Tiangong-1/Shenzhou-8 rendezvous and docking mission has achieved full success!”

Shenzhou-8 landed today at 7:30 pm. Beijing time in central Asia after flying nearly 17 days in earth orbit. Recovery crews reached the capsule within a few minutes of the parachute assisted touchdown.
Most of the flight was spent linked up to the Tiangong-1 Space Lab module – China’s first prototype space station.

After 12 days of joint orbital operations, Shenzhou-8 carried out a 2nd docking test to enable Chinese space engineers and mission controllers to gain further practice and experience in mastering the complex techniques involved in rendezvous and docking in space.
Shenzhou-8 disengaged from Tiangong-1 on Nov. 14, backed off to a distance of 140 meters (460 ft) and then carried out a re-docking about 30 minutes later. Controllers at the Beijing Aerospace Control Center monitored systems as Shenzhou-8 automatically re-approached Tiangong-1 for the second link up.
The main purpose of the second docking test was to confirm the performance of the rendezvous and docking procedures and hardware on Shenzhou-8 and Tiangong-1 under conditions of the glare of sunlight which are different compared to nighttime conditions of the first docking attempt.
Although the Shenzhou-8 flew unmanned during this flight, the capsule was fully human rated – even food and water are stored on board to simulate the presence of a human crew.
Today’s success sets the stage for possibly two Chinese manned missions to follow in 2012, namely Shenzhou-9 and Shenzhou-10.
Each Shenzhou can carry two or three astronauts. One of the missions is highly likely to include the first female Chinese astronaut.

Chinese space prowess took another major leap forward today (Nov. 14) when the unmanned Shenzhou-8 capsule successfully re-docked with China’s Tiangong-1 space lab while speeding through space and orbiting some 343 km above Earth. Today’s events pave the way for China to rapidly ramp up their human space program and loft up to two manned flights to the space lab module in 2012.
The re-docking marked only the 2nd time that China had accomplished a successful space docking, a critical technical milestone that opens the door to China’s real ambition of assembling a 100 ton operational Space Station in low Earth orbit by 2020 – about the time when the ISS might be decommissioned.
China made space history on Nov. 3 by becoming only the 3rd country on Earth – after the US and the Russia – to accomplish a space link up when Shenzhou- 8 and Tiangong-1 rendezvoused and docked in earth orbit.

Shenzhou-8 was launched to orbit on Nov. 1 atop a Long March 2F booster rocket from the Jiuquan Satellite Launch Center in the Gobi Desert in northwest China. The two Chinese built spacecraft have been joined together for 12 days.
China’s space re-docking exercise today came just hours after Russia successfully launched their Soyuz capsule with two Russians and one American bound for the ISS.

Today’s goal was to give Chinese engineers more practice and confidence in mastering the complex maneuvers required for rendezvous and docking two vehicles in space. It was carried out in daylight conditions as opposed to the nighttime conditions for the initial docking to expand the testing envelope under different scenarios.
Shenzhou-8 first disengaged from the prototype space station at about 6:37 a.m. EST and then withdrew to a distance of about 140 meters (460 ft). About 30 minutes later, mission controllers at the Beijing Aerospace Control Center monitored Shenzhou-8 as it automatically approached Tiangong-1 and completed the second docking – or “Space Kiss” as the Chinese media fondly say – at about 6:53 a.m. EST.

The combined Shenzhou-8/Tiangong-1 orbiting complex is some 20 meter in length and weighs about 16 tons. Each vehicle weighs some 8 tons. Tiangong-1 is 10.4 m in length and 3.3. m in diameter. Shenzhou-8 is 9.2 m in length
Shenzhou is China’s manned space capsule but flew this flight with no humans aboard because Chinese space officials felt it was safer and prudent and did not want to expose astronauts to excessive risk during the unprecedented docking attempts.
Following today’s complete success, the China Manned Space Engineering (CMSE) Project is pushing ahead with plans to launch up to two manned missions to Tiangong-1 in 2012 – namely Shenzhou-9 and Shenzhou-10 which are already under construction.
Both 2012 missions would be short duration flights of a few days or weeks since the Tiangong-1 module is a prototype space station module and not outfitted for long duration flights.
CMSE is evaluating a pool of Chinese astronauts already in training – including two women – for the two flights. Both women candidates are married and about 30 years of age but have not been publically identified.
It seems highly likely that one of the Shenzhou missions will include the first female Chinese astronaut.
So far China has launched six astronauts on three manned Shenzhou capsules between 2003 and 2008.
The docking mechanism on Shenzhou-8 was developed and manufactured in China, says Wu Ping, spokeswoman for the CMSE.
In two days, Shenzhou-8 is due to undock from Tiangong-1 for the final time and initiate the fiery re-entry to Earth on Nov. 17. The descent capsule will land by parachute.
These historic feats prove that China’s manufacturing and technological capabilities are surging forward and rapidly matching the Western powers and Japan in a broad swath of scientific and technical fields.
Since the forced retirement of NASA’s functioning space shuttle orbiters, only China and Russia can launch people into space.

China today launched the Shenzhou-8 capsule on a historic mission to accomplish the nation’s first ever docking in space with another vehicle, already in orbit, and pave the way toward’s China’s true ambition – constructing a multi-module space station by 2020.
The unpiloted Shenzhou-8 streaked skywards today in a blinding flash atop a powerful and upgraded Long March 2F/Y8 carrier rocket in the early morning darkness and precisely on time at 5:58 a.m. Beijing time (5:58 p.m. EDT) from the Jiuquan Satellite Launch Center in the Gobi Desert in northwest China. Viewers could watch a live CCTV broadcast from state media broadcast in English.
The Long March first stage is augmented with four liquid fueled strap on boosters. Spectacular TV views show the boosters and payload fairings being jettisoned.
The goal of the mission is for China to master critical and complex rendezvous and docking technologies and link up with China’s 1st orbiting prototype space station module dubbed Tiangong-1, or Heavenly Palace-1.

The historic docking of Shenzhou-8 with Tiangong-1 will be a highly significant achievement and is set to take place after the capsule catches up with the module in two days time. Tiangong-1 has been orbiting Earth since it was launched a month ago from the same launch site.
“The Launch of Shenzhou 8 has been a great success !”, announced Gen. Chang Wanquan, the Commander in Chief of China’s manned space program known as the China Manned Space Engineering (CMSE) Project. Chang, dressed in his military uniform, is Commanding Officer of Tiangong 1/Shenzhou 8 Rendezvous and Docking Mission Headquarters, and director of the PLA (Peoples Liberation Army) General Armaments Department.

“The Shenzhou 8 spaceship has entered at 6:07:53 its operating orbit with a perigee height of 200 km and apogee height of 329 km.”
The unmanned Shenzhou capsule entered orbit 585 seconds after liftoff while flying over the Pacific Ocean and placed the spacecraft into an initial elliptical orbit.
Shenzhou-8 will conduct five orbital maneuvers by firing its on board thrusters to match orbits and close in Tiangong-1 over the next two days and is on course for the linkup. Each vehicle weighs about 8 tons.
The two vehicles will remain docked for 12 days. Shenzhou-8 will then undock and separate and attempt another practice docking.
After several more days of joint operations the Shenzhou-8 capsule will depart and reenter the earth as though it had a crew.
Shenzhou-8 is fully equipped to carry an astronaut crew and even food and water are stored on board.
Today’s success sets the stage for two Chinese manned missions to follow in 2012, namely Shenzhou 9 and Shenzhou 10. They will each carry two or three astronauts.

The Tiangong-1 target module was launched from Jiuquan on September 29 and is functioning perfectly. Its orbit was already lowered and the ship was rotated 180 degrees in anticipation of today’s liftoff.
The Long March 2F booster is the tallest, heaviest and most powerful in China’s rocket arsenal.
China’s state run CCTV carried the launch live and provided excellent and informative commentary that harkened back to the glory days of NASA’s Apollo moon landing project. The Chinese government and people take great pride in the accomplishments of their space program which is vaulting China to the forefront of mastering technologically difficult achievements.
Long range tracking cameras and on board cameras captured exquisite views of Shenzhou-8 maneuver all the way to orbit, including separation of the first stage booster, jettison of the payload fairing, firing of the 2nd stage engines, deployment of the twin solar arrays, live shots inside the capsule and beautiful views of mother Earth some 200 kilometers below.
