China plans first commercial rocket company

9:13 am

The competition heats up: A Chinese company has announced plans to start a new commercial rocket company to compete for the burgeoning space launch market.

China Sanjiang Space Group Co. is preparing to enter the commercial-rocket business with a launch slated for 2017, Xinhua reported Tuesday, citing the company’s chief engineer Hu Shengyun. Some Internet companies have expressed interest in collaborating on commercial launches, Hu said.

The Kuaizhou-11, translated as “fast vessel,” rocket is being developed by the Fourth Academy of China Aerospace Science & Industry Corp., a major missile supplier to the People’s Liberation Army, according to China Daily.

There is not much information at the link. The rocket was first launched in 2013, but not much has been revealed about it since.

More details about China’s space station, planned for launch in 2020

10:00 am

The competition heats up: The chief designer of China’s human space program revealed more details today about their planned space station in talking with reporters at China’s on-going parliamentary sessions.

Zhou Jianping, speaking to state media on the sidelines of China’s ongoing parliamentary sessions, explained that the project will include three modules, two 30m solar panel ‘wings’, two robotic arms and a telescope dubbed ‘China’s Hubble’. Zhou, who is a member of China’s top consultative body currently in session in Beijing, said the space station will comprise of a core module and two labs forming a T-shape, each weighing about 20 tons.

The core module is scheduled to be launched in 2018, by the new heavy lift Long March 5 rocket, which will make its maiden flight in September and be capable of lifting 25 tonnes to low Earth orbit.

“China’s Hubble” will be a module flying near the station so that if it needs maintenance the station astronauts will be able to do the work.

China’s next manned mission

9:55 am

The competition heats up: The next Chinese manned mission will occur in the fall of 2016 and will have the astronauts remain in space for 30 days on a new space station launched during the summer.

After the astronauts have completed their flight, China will then launch their first unmanned cargo craft, dubbed Tianzhou-1, to dock with the station, using a new medium-lift rocket, Long March 7, which will get its first test flight this coming June.

China releases images from lunar rover and lander

10:33 am

Yutu on the Moon

China has made available a new batch of very cool images taken by its Chang’e 3 lander and Yutu rover, and Emily Lakdawalla at the Planetary Society has figured out how to view them.

In a recent guest blog post, Quanzhi Ye pointed to the Chinese version of the Planetary Data System, and shared the great news that Chang’e 3 lander data are now public. The website is a little bit difficult to use, but last week I managed to download all of the data from two of the cameras — a total of 35 Gigabytes of data! — and I’ve spent the subsequent week figuring out what’s there and how to handle it.

So, space fans, without further ado, here, for the first time in a format easily accessible to the public, are hundreds and hundreds of science-quality images from the Chang’e 3 lander and Yutu rover. I don’t usually host entire data sets (PDS-formatted and all) but I made an exception in this case because the Chinese website is a bit challenging to use.

The image above is a cropped version of Yutu, taken by the lander. Be sure and go to the link to see the full image as well as others.

New China manned vehicle under development

7:42 pm

The competition heats up: China has begun development of two versions of a second generation manned capsule.

Instead of the three-module arrangement of the current Shenzhou vehicle, the future Chinese crew vehicle will adopt a two-module arrangement, with a large inhabitable crew module at the front, and an uninhabitable cylindrical-shaped service module at back. The size of the re-entry vehicle will be twice of Shenzhou’s, capable of accommodating up to six crew members. A docking port and its associated docking sensors are fitted to the front-end of the crew module. The spacecraft can be fitted with two different service modules, with different propulsion systems and propellant capacities.

In other words, rather than copy and upgrade the design of the Russian Soyuz, as they did with their Shenzhou capsule, they will copy and upgrade the American Apollo capsule.

China unveils model of planned 2020 Martian probe

7:58 am

The competition heats up: China today unveiled a one-third scale model of its planned Martian lander/rover, scheduled for launch in 2020.

If they succeed in putting a lander and rover on Mars, China will have clearly demonstrated the capability to do almost anything in space that the United States can do. The competition in the coming decades should thus be most interesting.

Yutu still operational after two years

8:15 am

Despite an inability to move, China’s rover Yutu has now set the longevity operational record for rover on the Moon.

Yutu was deployed and landed on the moon via China’s Chang’e-3 lunar probe in 2013, staying longer than the Soviet Union’s 1970 moon rover Lunokhod 1, which spent 11 months on the moon. Its operations have streamed live through Sina Weibo, a Chinese microblogging site, and its Weibo account has nearly 600,000 followers.

Yutu experienced a mechanical control abnormality in 2014, but it was revived within a month and, though it is unable to move, it continues to collect data, send and receive signals, and record images and video.

Two NASA employees indicted for allowing Chinese scientist access

8:37 am

Two NASA supervisors from the Langley Research Center in Virginia have been indicted for allowing a Chinese scientist unrestricted access to the facilities there for two years, including allowing the scientist to return to China with a NASA-issued laptop.

What I find amazing about this indictment is that a U.S. attorney in the Obama Justice Department has issued it. The Obama administration and NASA administrator Charles Bolden want unrestricted cooperation with China, and have even done some things that could also violate the same laws against providing U.S. technology to China. Under these conditions, I would have thought the attorney would have been ordered to drop the case, just as the Obama administration has done with numerous other examples where someone in that administration did something illegal and got away with it.

China launches first commercial Earth-observation satellite

9:21 am

The competition heats up: China today successfully launched its first Earth-observation satellite for providing commercial images to the public.

A Long March 2C rocket launched the Jilin 1 satellite constellation, which consists of a primary high definition optical satellite, as well as two Lingqiao video satellites and a fourth, LQSat, to test space technology. Xuan Ming, from the Chang Guang Satellite Technology Co., Ltd, earlier told Xinhua the satellites will focus on providing images to commercial clients, while helping with harvest assessment, geological disaster prevention and resource surveys. Jilin-1 is reported to be capable of very high definition images, boasting a resolution of 0.72m with a pan-chromatic camera and a 4m resolution multi-spectral camera.

The article also provides a short but nice summary of China’s space plans for 2016, including its first manned mission since 2013.

Long March 6 launch a success

9:12 pm

The competition heats up: The first launch of China’s smallsat rocket Long March 6 was a success on Saturday, putting 20 satellites into orbit.

This rocket is part of a new family of Chinese rockets, modularly designed so that can be reconfigured depending on payload or mission. The big launch however will be next year, when they attempt the first test flight of the largest member of this family.

China to launch new rocket today

7:54 am

The competition heats up: With the expected first launch of China’s new Long March 6 rocket today, this report nicely outlines the status of the country’s rocket program.

Like Russia’s Angara and SpaceX’s Falcon, the new generation of Long March rockets are modular and use the same rocket engine. This has reduced cost and allows for faster assembly. The launch today is the maiden flight of the smaller member of this family. The key launch will be that of the larger Long March 5, scheduled for next year. Capable of putting 25 tons in orbit (five more than Proton), this is the rocket they plan to use to launch the modules for their full-sized space station.

Chinese scientists do genetic experiments with human embryos

11:22 pm

What could possibly go wrong? A Chinese team of scientists have been experimenting with genetically manipulating the human embryo to see if they can prevent a genetic blood disorder.

The team attempted to modify the gene responsible for β-thalassaemia, a potentially fatal blood disorder, using a gene-editing technique known as CRISPR/Cas9. The researchers say that their results reveal serious obstacles to using the method in medical applications. “I believe this is the first report of CRISPR/Cas9 applied to human pre-implantation embryos and as such the study is a landmark, as well as a cautionary tale,” says George Daley, a stem-cell biologist at Harvard Medical School in Boston. “Their study should be a stern warning to any practitioner who thinks the technology is ready for testing to eradicate disease genes.”

They not only found the technique unreliable in curing the genetic disease, it also produced many more unpredicted mutations.
