China’s National Space Science Center (CAS) has unveiled a newly developed helicopter which could be used in the country’s exploration of the Red Planet. The new tool comes months after China landed a robotic rover on Mars.

On Wednesday, CAS reported that China had developed the miniature helicopter, and Chinese media released images online of the astronomical equipment.

China’s state-affiliated media channel, the Global Times, said that researchers from CAS recently approved the Beijing Science & Technology Commission’s examination of their Mars drone prototype, “which will enable Chinese scientists to further explore Mars.”

In May, China historically landed a rover on Mars in its inaugural mission to the planet, as part of the country’s ambitious future space exploration plans.

Last week, the rover, named Zhurong, marked its 100th day working on Mars’ surface and clocked the 1,000-meter milestone of land covered driving south from its landing point.

Earlier this year, Wang Xiaojun, head of the state-owned China Academy of Launch Vehicle Technology, said that Beijing envisages building a permanent presence on Mars and large-scale development of its resources, with a fleet of vessels running between the Red Planet and Earth.
While the Mars helicopter is no more than what the US has already done, the building of a Chinese permanent base on Mars may come sooner than anybody else's.

China eyes manned lunar landing by 2030
By Deng Xiaoci - Published: Aug 30, 2021 08:58 PM

https://www.globaltimes.cn/page/202108/1232862.shtml

Leading Chinese rocket scientist Long Lehao has recently unveiled the country's ambitious manned lunar landing plan, which is expected to be carried out with two rocket launches by sending two taikonauts to the moon by around 2030. Long's comment offers a more detailed picture of the country's major breakthrough in space exploration.

Image

Long, an academician of the Chinese Academy of Engineering and chief designer of Long March rockets, made the remarks at the 35th China Adolescents Science and Technology Innovation Contest, and a video of his speech went viral on social media late on Sunday night.

China is planning to use new variants of the Long March-5 launch vehicle - the strongest member of the Long March rocket family - to carry out the manned space launch missions, according to a slide Long used during his speech.

The 57-meter-long Long March-5 launch vehicle weighs 870 tons at launch and has a thrust of 1,000 tons. It is a large, two-stage rocket, capable of carrying a payload of 25 tons, equivalent to the weight of 16 cars, to low Earth orbit. It can carry a payload of 14 tons to geostationary transfer orbit, eight tons to Earth-moon transfer orbit, or five tons to Earth-Mars transfer orbit - more than twice the capacity of the current main Long March series rockets.

Long referred the new variant as Long March-5 DY, which is initials for the Chinese term of dengyue, the lunar landing.

Two rockets carrying a lunar lander and a next-generation manned spaceship will be launched for the mission, and the two parts of the spacecraft will rendezvous and dock in near-lunar orbit, before executing the landing process.

The two taikonauts are expected to work on the moon's surface for some six hours, according to Long's slide. However, there is no mention of a specific landing site.

Then, the new manned spaceship will take off from the moon and carry out another docking with the orbiting module before heading back to Earth.

When asked to confirm such new clues on China's manned lunar landing, sources with the China Academy of Launch Vehicle Technology, the major contractor of China's space projects and rocket manufacturer, said the project has yet to obtain state approval. But the sources did reveal that there will be a special press release on the matter during the China International Aviation and Aerospace exhibition, which is to be held in Zhuhai, South China's Guangdong Province in late September and early October.

Chinese space analysts reached by the Global Times on Monday said that such clues were very credible, as the two-rocket moon landing plan with Long March-5 variants, which they said would be immensely reliable and safe, is in line with the Chinese space sector's tradition of "standing firmly and fighting steadily."

Compared with the much-anticipated new heavy-lift launch vehicle, or the Long March-9, rumor has it that the variant of the Long March-5 is more likely to meet the timetable of 2030. Testing of the new rocket would normally take a long time and even longer when it comes to manned missions, where the safety of astronauts is paramount, Wang Ya'nan, chief editor of Beijing-based Aerospace Knowledge magazine, told the Global Times on Monday.

Space analysts saw similarities between China's plan and the one for US Blue Origin's initial Human Landing System mission, which requires three commercial launches for the manned lunar landing. And according to the US firm, it is a way to lower the risk of mission failure due to launch anomalies.

One early-stage Soviet Union crewed lunar mission also used two launches and docking, Pang Zhihao, a senior space expert, told the Global Times on Monday, underscoring China's manned lunar landing is of great feasibility.

From the slide with Long's speech, a Long March-5 rocket body is seen with an escape tower atop, which is similar to the one on top of China's current and only manned rocket Long March-2F.

Wang speculated that the development of a Long March-5 DY variant supporting manned flights would be a rather simple task for China's space sector within the time frame.

Well said. And that kilometre long spaceship thing was complete bollocks -- I know that the Chinese are willing to spend ridiculous amounts of money on the appearance of progress, but they just got to LEO a few years ago, and they're not going from the 1960's to the 2060's in one fell swoop.

Without all those American gadgets to copy, the rest of us would still be in the Stone Age... :D

Yet they would have us believe otherwise.

China to debut new manned rocket, heavy-lift launch vehicle for moon landings at Airshow China
By Deng Xiaoci - Published: Sep 23, 2021 08:20 PM
https://www.globaltimes.cn/page/202109/1234962.shtml

Coming amid the country's busy yet smooth execution of missions to build its most ambitious manned space project - the China Space Station - the China Academy of Launch Vehicle Technology (CALT), the nation's largest organization for research, development and production of missiles and carrier rockets, will debut a next-generation manned carrier rocket and a heavy-lift launch vehicle, at this year's Airshow China in Zhuhai, South China's Guangdong Province from September 28 to October 3.

The rocket and launch vehicle are expected to support China's manned lunar probes. The next-generation carrier rocket, freshly developed by the CALT, will be the go-to rocket to launch the country's next-generation manned spacecraft.

Consisting of three core stages and an escape tower as well as a nose cone, the rocket is 90 meters long and weighs about 2,000 tons at launch, the Global Times learned from the CALT on Thursday.

It is capable of sending a payload of 25 tons directly into moon transit orbit or a payload of 70 tons into near-Earth orbit, the CALT said in a press release it sent to the Global Times.

It can also combine with multiple modules to formulate a stream of rocket types that can carry payloads of 40 to 70 tons into low-Earth orbit or 10 to 32 tons into geostationary transfer orbit. It can also achieve the reusability of vertical take-off and vertical landing, when using multiple engines in parallel layout, the CALT said.

The new rocket will be used to conduct China's manned lunar probe missions, the CALT noted. It has completed ignition tests of the new pump rear swing high-pressure supplementary combustion engine, the solid adjustable thrust attitude control engine, and the new non-toxic attitude control engine.

The name of the next-generation manned rocket has not been officially disclosed. But many space observers reached by the Global Times speculated it might be called "921 rocket." The number 921 refers to the time when the manned space project was first approved by the state authority 29 years ago on September 21.

Long Lehao, an academician of the Chinese Academy of Engineering and chief designer of Long March rockets, has previously said that such rocket for manned lunar landings will be called Long March-5 DY, an acronym for the Chinese term dengyue, or lunar landing.

Also set to debut in Zhuhai is the heavy-lift launch vehicle, which is speculated to be named Long March-9.

It is developed to be the strongest member of China's launch vehicle family and is designated to execute manned lunar probes, among other deep-space exploration missions, the CALT said.

The feasibility study of the type started in 2010 by the China National Space Agency. The 9.5-meter-diameter rocket has four 5-meter-diameter boosters, with each carrying two 4,800-kilonewton liquid oxygen methane engines, according to the academy.

With three core stages, it can launch payloads of up to 140 tons into new Earth orbit, 50 tons into lunar transit orbit and 35 tons into Mars transit orbit.

It is scheduled to conduct its maiden flight around 2028, the CALT disclosed.

It also added that it will support deep-space exploration missions as well as the building of a moon base, ensuring the country's launch vehicle technology will advance to world-class level by around 2030.
Are they copies of American rockets? Can only be, seeing that the Chinese are incapable of inventing anything...

Oh, I don't know. This is technology the Americans had in the 1960's, so the Chinese might have come up with it on their own by now.

The article states that these rockets are fully reusable. So these are the same as 1960's rockets. SO basically the XiCP has skipped over making Falcon 9 and gone directly yo Falcon Heavy. *If* their claims are true. Which indicates they did not spend much time learning how to do this on their own.
