China reveals its space station plans.

“China Space Station (CSS) will operate in orbit from 2022 to 2032. This period will provide much more opportunities to scientists in China and all of the world after the international space station,” Gu Yidong, president of the China Society of Space Research, said at the American Society for Gravitational and Space Research conference here Nov. 3 – 8. The station’s core module is slated to launch in 2018, followed by two laboratory modules in 2020 and 2022. The outpost will be located in an orbit ranging from 350 kilometers to 450 kilometers above Earth and inclined 42 degrees relative to the planet’s equator.

The article describes in detail their research plans on their station, which sound much the same as the kind of research done on ISS. I suspect this is a bit of misdirection. Their station is clearly designed as a prototype interplanetary station, much like Mir. I believe that any research they do on it will be focused around that fact, which will make that research significantly different that the work done on ISS, which is often not very effective and poorly focused.

Some new details about SpaceX’s new Raptor rocket engine are revealed.

9:19 am

The competition heats up: A key new detail about SpaceX’s new Raptor rocket engine is revealed.

The only detail about the engine in the release noted it will be capable of generating nearly 300 tons of thrust in vacuum, around four times more powerful than the Merlin 1D. However, it is possible a Raptor engine set could become the baseline for a huge future rocket to be used by SpaceX for missions to Mars, along with a potential role with a Mars ascent stage. [emphasis mine]

It appears that the engine might be intended to replace the Merlin engine entirely, thus giving the Falcon 9 (and other future SpaceX rockets) significantly more power, both for putting payload into orbit as well as returning to the ground.

Meanwhile, it also appears the Chinese, who are SpaceX’s biggest competitor in terms of price, are developing their own methane-oxygen engine with likely similar capabilities.

Ain’t competition wonderful?

China complains about the ban of its scientists at a NASA Kepler conference.

China complains about the ban of its scientists at a NASA Kepler conference.

The meeting is a key event for scientists searching for planets beyond the solar system. NASA has rejected applications from Chinese nationals, citing a new security law. In Beijing, foreign ministry spokeswoman Hua Chunying called the move “discriminatory”. The conference is for US and international teams who work on Nasa’s Kepler space telescope program. It will be held at Nasa’s Ames research centre in California next month.

And I say, tough. China does not distinguish between civilian and military research, and in fact has often used its scientists to do espionage, stealing both military and industry secrets in the process.

China today successfully launched a new quick response rocket.

9:57 am

The competition heats up: China today successfully launched a brand new quick response rocket.

Very little is known about the Kuaizhou rocket, other than it was developed by CASIC. No photos or graphics exist in the public domain. It is also known the rocket – likely on its test flight – was carrying a satellite, called Kuaizhou-1. Built by the Harbin Institute of Technology, the new satellite will be used for emergency data monitoring and imaging, under the control of the national remote sensing center at the national Academy of Sciences. The new satellite is probably part of a “quick response satellite system” model that was already announced as in the works by the Chinese.

The rocket appears to be fueled entirely by solid rocket motors. Thus, they could build a bunch and have them in storage, ready to go at any time.

China announced today that it plans to hold the launch cost of its Long March rockets at $70 million per launch.

The competition heats up: China announced today that it plans to hold the launch cost of its Long March rockets at $70 million per launch.

Until Space Exploration Technologies Corp. (SpaceX) of Hawthorne, Calif., arrived on the scene with advertised launch prices that bested even those of the Chinese, the Long March was considered the low-cost option among providers of rockets carrying satellites to geostationary transfer orbit, where most communications satellites are dropped off in orbit. [Chinese] officials point out that SpaceX has yet to prove its ability to maintain its prices – between $58 million and around $65 million for commercial customers – as it inaugurates its new Falcon 9 v1.1 rocket and ramps production to meet the company’s large commercial backlog.

China is gambling that its proven track record will entice customers to pay them the extra money over SpaceX’s unproven Falcon 9.

The competition heats up: China’s first unmanned lunar lander is now scheduled for launch before the end of the year.

This mission is the second stage in their long term plans for unmanned lunar exploration. It began with an orbiter which mapped the surface in high detail, followed now by a lander, which will then be followed by a sample return mission.

The Chinese astronauts have undocked from the Tiengong-1 space station and will return to Earth tomorrow.

9:03 am

The Chinese astronauts have undocked from the Tiengong-1 space station and will return to Earth tomorrow.

Following a separation from the Tiangong-1 at 7:05 a.m. Beijing Time, the manned Shenzhou-10 moved back to a point from where the spacecraft changed its orbit and flew around the target module. Under the command of ground-based professionals, Shenzhou-10 adjusted its flight gesture at a point behind Tiangong-1, and approached and rendezvoused with the target module.

The fly-around and rendezvous was apparently controlled by ground controllers, not the astronauts on board.

A new Defense Department report says that China is aggressively ramping up its space program.

The competition heats up: A new Defense Department report says that China is aggressively ramping up its space program.

China will continue to augment its orbiting assets, with the planned launch of 100 more satellites through 2015. These launches include imaging, remote sensing, navigation, communication and scientific satellites, as well as manned spacecraft.

China is pursuing a variety of air, sea, undersea, space, counterspace and information warfare systems, as well as operational concepts, moving toward an array of overlapping, multilayered offensive capabilities extending from China’s coast into the western Pacific. China’s 2008 Defense White Paper asserts that one of the priorities for the development of China’s armed forces is to “increase the country’s capabilities to maintain maritime, space and electromagnetic space security.”

Further, China continues to develop the Long March 5 rocket, which is intended to lift heavy payloads into space. LM-5 will more than double the size of the Low Earth Orbit (LEO) and Geosynchronous Orbit (GEO) payloads China is capable of placing into orbit. To support these rockets, China began constructing the Wenchang Satellite Launch Center in 2008. Located on Hainan Island, this launch facility is expected to be complete sometime this year 2013, with the initial LM-5 launch scheduled for 2014.

The Chinese national who had been arrested at Dulles airport as he left for China with a NASA laptop has been released after pleading guilty to one charge, having porn on the laptop.

The Chinese national who had been arrested at Dulles airport as he left for China with a NASA laptop has been released after pleading guilty to one charge, having porn on the laptop.

Investigators found no classified information on the computer. As part of the release agreement, however, the man must leave the U.S.

Though the man, Bo Jiang, was very careful to bring nothing secret with him when he tried to flee to China in March, the circumstantial evidence suggests that he should not have had access to this information in the first place, and that in the past he might have illegally funneled classified information to China.

A Chinese scientist who worked as a contractor for NASA was arrested yesterday on a plane about to leave for China.

A Chinese scientist who worked as a contractor for NASA was arrested yesterday on a plane about to leave for China.

Agents learned Friday that Jiang was to return to China on a one-way ticket Saturday, the affidavit said. He flew from Norfolk to Dulles International Airport outside Washington, where he boarded a plane bound for Beijing. Federal agents pulled him off the flight and searched his belongings. During what they called a “consensual encounter,” the agents asked Jiang what electronic media he had with him. He told an agent from the Department of Homeland Security that he had a cellphone, a memory stick, an external hard drive and a new computer.

But during the search, according to the affidavit, agents found an additional laptop, an old hard drive and a portable memory chip called a SIM card. He was arrested, and made his initial court appearance Monday.

It appears that the restrictions Congress placed on hiring foreign nationals had some merit. Moreover, it appears that the accusation by one congressman that NASA has been trying to circumvent those restrictions is true.

China’s next manned mission is now set for this summer.

12:47 pm

The competition heats up: China’s next manned mission is now set for this summer.

The Shenzhou 10 spacecraft will take flight sometime between June and August, the program said in a statement. It will deliver its crew to the Tiangong 1, where it will spend two weeks conducting tests of the station’s docking system and its systems for supporting life and carrying out scientific work.

An update on the Chinese manned program.

9:29 am

An update on the Chinese manned program.

The original script called for [the space station] Tiangong 1 to be followed by Tiangong 2, which would have been a module of the same basic design as Tiangong 1. Tiangong 2 was expected to have tested more advanced life-support systems than Tiangong 1, but there would be no major changes to the spacecraft. It was expected that two or three crews would be launched to this module.

Towards the end of the decade, China would then launch Tiangong 3, which was slated to be an entirely different class of spacecraft. It would be larger and more capable. Tiangong 3 was expected by some analysts to be a precursor to the types of modules to be used in China’s future space station, slated for launch around 2020.

According to Yang’s presentation, we can forget about Tiangong 2. Or at least, we can forget about Tiangong 2 as it was originally planned. China still plans to launch a mission with this name, but it would seem that the large laboratory module originally known as “Tiangong 3” has now been designated as the new Tiangong 2.

In other words, China is accelerating the admittedly slow pace of their manned program.

Is the recently discovered Imperial tomb in China too dangerous to enter?

Is the recently discovered Imperial tomb in China too dangerous to enter?

After discovering a secret palace hidden in China’s first emperor massive burial complex, Chinese technicians are nervous. Not because Qin Shi Huang’s tomb is the most important archeological discovery since Tutankhamun, but because they believe his burial place is full of deadly traps that will kill any trespassers. Not to talk about deadly quantities of mercury.

The secret courtyard-style palace tomb is a mind-numbing discovery. Situated in the heart of the Emperor’s 22-square-mile (56-square-kilometer) mortuary compound guarded by more than 6,000 (and counting) full-size statues of warriors, musicians and acrobats, the buried palace is 2,263 by 820 feet (690 by 250 meters). It includes 18 courtyard houses overlooked by one main building, where the emperor is supposed to be. The palace—which has already been partially mapped in 3D using volumetric scanners—occupied a space of 6,003,490 cubic feet (170,000 cubic meters). That’s one fourth the size of the Forbidden City in Beijing—for just one tomb.

Experts believe that the 249-foot-high (76-meter) structure covered with soil and kept dry thanks to a complex draining system, hides the body of the emperor and his courtiers. Nobody knows what’s the state of their bodies, but one of the leading archeologists believes that they are most likely destroyed by now.

China’s Chang’e 2 lunar probe, now out of lunar orbit, did a fly-by of the 3 mile wide asteroid Toutatis as it zipped past the Earth last week, resulting in some spectacular images.

China’s Chang’e 2 lunar probe, now out of lunar orbit, did a fly-by of the 3 mile wide asteroid Toutatis as it zipped past the Earth last week, resulting in some spectacular images.

Launched on October 1, 2010, Chang’e 2 orbited the Moon for 8 months before being redirected last year to the L2 Lagrange point, roughly a million miles on the side of Earth opposite the Sun. But when it left L2 last April, Western observers suspected the spacecraft was heading deeper interplanetary space. It didn’t take long to realize that Chang’e 2 was bound for Toutatis.

This is an example of a very smart re-use of a space probe.

By the way, the first fly-by of another planet took place fifty years ago this week.
