China had a highly successful year in space in 2013, sending a second crew to live aboard the Tiangong-1 space station in June and becoming only the third nation to successfully soft land a spacecraft on the moon in December. As the year ended, the Yutu rover had completed its first exploration of the lunar surface and had entered a hibernation period for a long lunar night.

With increasingly sophisticated spacecraft, a reliable stable of Long March launch vehicles, and ambitious plans for the future, China has made itself a major player in the international space arena as space agencies in the United States and Europe face budgetary pressures and Russia struggles to revive a once formidable space program.

2013 Launch Record

The nation made 15 launches in 2013, down from the 19 it accomplished in 2012. That total placed the nation’s space program in third place behind Russia and the United States, respectively.

The successful year was marred by the rare failure of a Long March 4B on Dec. 9 that destroyed the $250 million Chinese-Brazilian CBERS 3 environmental satellite. Chinese officials say one of two upper stage engines did not fire as planned, causing the spacecraft to fall back into the atmosphere.

China debuted a new launch vehicle in 2013. The Kuaizhou rocket made a successful flight from Jiuquan on Sept. 25, orbiting the Kuaizhou 1 satellite. The small satellite launch vehicle is believed to be designed to allow China to quickly orbit military satellites.

Human Spaceflight: Steady as She Goes

On June 11, the Shenzhou 10 spacecraft bound for the Tiangong-1 space station blasted off from the Jiuquan spaceport aboard a Long March 2F rocket. Nie Haisheng, Zhang Xiaoguang and Wang Yaping spent 15 days in space conducting experiments and testing technologies before touching down safely on June 26 in Inner Mongolia.

Shenzhou 10 was the second and final human mission to China’s first space station, which at 10.4 meters (34 feet) in length is approximately half the size of the Salyut stations flown by the Soviet Union in the early 1970’s. The flight came one year after the crew of Shenzhou 9 visited the station during a 13-day space mission.

China’s human spaceflight program has been slow and steady. Shenzhou 10 was only the fifth human mission in nearly 10 years. It’s unclear when the next flights will occur, but given the pattern they will likely follow the launch of the Tiangong-2 space station now scheduled for 2015.

Tiangong-2 will resemble the Soviet Union’s second-generation Salyut 6 space station in size, form and function. The advanced station will be lengthened to 14.4 meters (47 feet) and boast two docking ports. The additional docking port will allow automated freighters to resupply the station.

The Tiangong stations are precursors to a permanent, multi-module facility that China plans to have operational around 2020. The first module of the station is set for launch in 2018, followed by other elements in future years.

China has begun marketing the multi-module station as a place for international cooperation with the expectation that the U.S.-led International Space Station will be de-orbited in 2020. NASA wants to extend ISS operation to 2028, but it is not clear whether the space agency’s international partners – Canada, Japan, Europe and Russia – will agree to the extension.

European and Russian officials seem eager to cooperate with the Chinese space agency. However, NASA has been barred from any significant cooperation by Congressional action.

A Giant Leap in Lunar Exploration

On Dec. 1, a Long March 3B rocket lifted off from Xichange with China’s third lunar probe, Chang’e-3. The spacecraft touched down on the moon’s Bay of Rainbows on Dec. 14, achieving the first soft landing on the lunar surface in 37 years. Within hours of the landing, the Yutu (Jade Rabbit) rover rolled off the landing vehicle and began driving around the surface.

Yutu — which measures 1.5 m (4.9 feet) high and weighs 120 kg (260 lb) — is designed to explore a 3-square kilometer area of Sinus Iridum during a three-month mission. The vehicle is equipped with a camera, X-ray spectrometer, infrared spectrometer, and a radar unit that will measure the structure of the lunar soil down to a depth of 30 m (98 feet) and the lunar crust down to several hundred meters.

Yutu also has the capability to dig into the lunar soil and perform basic analyses of samples. Chinese scientists have equipped the rover with sensors for avoiding objects and the ability to to navigate inclines.

The landing vehicle is equipped with seven instruments and cameras that will study the moon and its environment separately.  The payload includes an astronomical telescope with an extreme ultraviolet camera that will be able to observe celestial bodies and study how solar activity affects the ion layer near Earth.

China is planning a sample return mission in 2017. It is possible that the country will land astronauts on the moon sometime in the 2020s, although there appears to be no firm schedule or funding for such missions as yet.

An ASAT Test?

On July 19, a Chinese Long March 4C blasted off from Jiuquan with the Shijian 15 military satellite, the Shiyan 7 technology demonstration satellite, and the Chuangxin 3 secondary payload. It’s what these spacecraft did once they were in orbit that has intrigued Western observers.

According to one report, one of the spacecraft captured another one in “what Pentagon officials say was a significant step forward for Beijing’s space warfare program. The satellite capture took place last week and involved one of three small satellites fitted with a mechanical arm that were launched July 20 as part of a covert anti-satellite weapons development program, said U.S. officials familiar with reports of the test.”

American officials are concerned such technology could be used to capture, disable or disassemble U.S. satellites in orbit, according to the report.

Ahead in 2014: A Blue Water Spaceport

Later this year, China will open its fourth and most modern spaceport on the northeast coast of Hainan Island. The Wenchang Satellite Launch Center (WSLC) is a former suborbital test center that is being upgraded with multiple orbital launch pads.

The new launch center is in a tropical location only 19 degrees from the equator, making it better for equatorial communications satellite launches and other missions than China’s three existing spaceports. Spent rocket stages will also drop over the ocean instead of over land as now occurs.

WSLC will be served by wide gauge railroad lines that are capable of handling the larger heavy-lift Long March 5 launch vehicle now under development. Scheduled for its initial test launch in 2015, Long March 5 will be capable of lifting up to 25 metric tons (27.5 tons) to low Earth orbit and 14 metric tons (15.4 tons) to geosynchronous transfer orbit.

    Just wondering… what would have to happen for the USA to say it had a stellar year… warp drive developed?

  • Douglas Messier

    I just said that the other day:

    “Coming off a stellar year, each of America’s three launch providers —
    Orbital Sciences Corporation, SpaceX and United Launch Alliance (ULA) —
    finds itself in a distinctly different place and facing unique
    challenges. The coming year could begin to significantly remake the
    global launch market, with significant consequences for all three
    players and rival providers overseas.”

    I wrote two stories focused on the success of U.S. launch providers in 2013 and looking at the challenges they face in the future:

    There was some refinement of the Alcubierre drive this year… at least on the theoretical physics side of things that suggest a human scale sized device might at least be possible (even if you may need a metric ton of anti-matter… but who is counting on such trivialities). Who knows? Anything is possible like that.

    I’d agree that to make a splash, the USA must not just send and return a crew to Mars, but likely to Alpha Centauri within a decade.

    Lifting 53mT to orbit on a reusable launcher would defiantly make it, in my book. Flying a commercial crew to orbit will make it as well

  • Stuart

    Hi Doug, I wasn’t making a personal dig at you or your good work. I am deeply worried though that excellent progress made in 2013 by the “commercial revolution” is I fear so little understood by the general public let alone dare I say US politicians. In many respects that role, I suppose, is our responsibility.

  • Douglas Messier

    Ah, OK. No problem. I seem to have misunderstood the remark.

  • Tonya

    It should be noted of course, that 53MT is the forecast payload for a disposable falcon heavy. The reusable payload is obviously reduced, but by how much is unknown and likely still TBD by SpaceX themselves.
