China scored a stunning, history making success with the successful touchdown of the ambitious Chang’e-3 probe with the ‘Yutu’ rover on the surface of the Moon today, Dec. 14, on the country’s first ever attempt to conduct a landing on an extraterrestrial body.

The dramatic Chang’e-3 soft landing on the lava filled plains of the Bay of Rainbows occurred at about 8:11 am EST, 9:11 p.m. Beijing local time, 1311 GMT today.

The monumental feat is the first landing on the Moon by any entity in nearly four decades. It was broadcast live on CCTV, China’s state run television network.

This maiden Chinese moon landing marks a milestone achievement for China and clearly demonstrates the country’s technological prowess.

A tidal wave of high fives was unleashed by the huge teams of Chinese space engineers teams controlling the flight from the Beijing Aerospace Control Center (BACC).

There was also a huge sense of relief from the nail biting tension upon confirmation of the successful soft landing following many years of hard work and intense planning.

The Chang’e-3 mission entails the first soft landing on the Moon by anyone since the Soviet Union’s unmanned Luna 24 sample return vehicle touched down back in 1976.

China now joins an elite club of three, including the United States, who have mastered the critical technology required to successfully touch down on Earth’s nearest neighbor.

China’s space vision also stands in total contrast to the utter lack of vision emanating from so called political leaders in Washington, DC who stymie NASA and US science at every opportunity!

‘Yutu’ could very well serve as a forerunner for testing the key technologies required for a Chinese manned lunar landing in the next decade.

In one of its first acts from the surface, the landers life giving solar panels were deployed as planned within minutes of touchdown

The Chang’e-3 mission is comprised of China’s ‘Yutu’ lunar lander riding piggyback atop a much larger four legged landing vehicle.

The Chang’e-3 lander transmitted its first images of the moon in real time during its approach to the lunar surface during the final stages of the ongoing landing operation carried live by CCTV.

A total of 59 images were received instead of the 10 expected, said a CCTV commentator.

The voyage from the Earth to the Moon began 12 days ago with the flawless launch of Chang’e-3 atop China’s Long March 3-B booster at 1:30 a.m. Beijing local time, Dec. 2, 2013 (12:30 p.m. EST, Dec. 1) from the Xichang Satellite Launch Center, in southwest China.

Chang’e-3 made a rocket powered descent to the Moon’s surface today by firing the landing thrusters starting at the altitude of 15 km (9 mi) for a soft landing targeted to a preselected area on the Bay of Rainbows.

The powered descent was autonomous and took about 12 minutes.

The variable thrust engine can continuously vary its thrust power between 1,500 to 7,500 newtons. It was the biggest ever used by China in space said a commentator on CCTV.

The variable thrust engine enabled Chang’e-3 to reduce its deceleration as it approached the moon.

The descent was preprogrammed and controlled by the probe itself, not from the ground.

A descent camera was mounted on the lander’s belly

The 1200 kg lander is equipped with unprecedented terrain recognition equipment and software to hover above the landing site and confirm it was safe. This enabled the craft to avoid rock and boulder fields that could spell catastrophe even in the final seconds before touchdown if the vehicle were to land directly on top of them.

The descent engine fired until the lander was about hovering 100 meters above the lunar surface.

After determining it was safe to proceed, the lander descended further to about 3 meters. The engine then cut off and the lander free fell the remaining distance. The impact was cushioned by shock absorbers.

The solar panels soon unfurled. They are the most efficient Chinese solar panels available, said a CCTV commentator.

The Bay of Rainbows, or Sinus Iridum region, is located in the upper left portion of the moon as seen from Earth. You can see the landing site with your own eyes.

It was imaged in high resolution by China’s prior lunar mission – the Chang’e-2 lunar orbiter – and is shown in graphics herein.

The Yutu rover is also unfurling its solar panels and mast today.

Yutu, which translates as Jade Rabbit, stands 150 centimeters high, or nearly 5 feet – human height.

It weighs approximately 120 kilograms and sports a robotic arm equipped with advanced science instruments.

On Sunday, the six-wheeled ‘Yutu’ rover with a rocker bogie suspension similar to NASA’s Mars rovers will be lowered in stages to the moon’s surface in a complex operation and then drive off a pair of landing ramps to explore the moon’s terrain for at least three months.

In what promises to be a space spectacular, the lander and rover are expected to photograph one another soon after Yutu rolls onto the Bay of Rainbows.

They will work independently.

The rover and lander are equipped with multiple cameras, spectrometers, an optical telescope, ground penetrating radar and other sensors to investigate the lunar surface and composition.

The radar instrument installed at the bottom of the rover can penetrate 100 meters deep below the surface to study the Moon’s structure and composition in unprecedented detail, according to Ouyang Ziyuan, senior advisor of China’s lunar probe project, in an interview on CCTV.

The Chang’e-3 lander is powered by a combination of solar arrays and a nuclear battery said CCTV, in order to survive the two week long lunar nights.

Chinese space officials expect the lander will function a minimum of 1 year.

ESA’s network of tracking stations are providing crucial support to China for Chang’e-3 from launch to landing.

China’s Chang’e-3 probe joins NASA’s newly arrived LADEE lunar probe which entered lunar orbit on Oct. 6 following a spectacular night time blastoff from NASA’s Wallops Flight Facility in Virginia.

China’s Chang’e-3 Moon Rover Descends to Lower Orbit Sets Up Historic Soft Landing

All systems appear to be “GO” for the world’s first attempt to soft land a space probe on the Moon in nearly four decades.

China’s maiden moon landing probe – Chang’e-3 – is slated to attempt the history making landing this weekend on a lava plain in the Bay of Rainbows, or Sinus Iridum region.

Chinese space engineers at the Beijing Aerospace Control Center (BACC) paved the way for the historic touchdown by successfully commanding Chang’e-3 to descend from the 100 km-high lunar circular orbit it reached just one week ago on Dec. 6, to “an elliptical orbit with its nearest point about 15 km away from the moon’s surface”, according to a statement from China’s State Administration of Science, Technology and Industry for National Defense (SASTIND).

UPDATE: CCTV is providing live landing coverage

The first pictures taken from the alien lunar surface in some 37 years are expected to be transmitted within days or hours of touchdown planned as early as Saturday, Dec. 14, at 9:40 p.m. Beijing local time, 8:40 a.m. EST.

CCTV, China’s state run network, carried the launch live. It remains to be seen whether they will have live coverage of the landing since there have been no programming announcements.

SASTIND said the orbit lowering thruster firing was “conducted above the dark side of the moon at 9:20 p.m.” on Dec. 10, Beijing local time.

Confirmation of the Chang’e-3 probes new, lower orbit was received four minutes later.

China’s Maiden Moon Rover Mission Chang’e 3 Achieves Lunar Orbit

China’s maiden moon landing probe successfully entered lunar orbit on Friday, Dec. 6, following Sunday’s (Dec. 1) spectacular blastoff – setting the stage for the historic touchdown attempt in mid December.

Engineer’s at the Beijing Aerospace Control Center (BACC) commanded the Chang’e 3 lunar probe to fire its braking thrusters for 361 seconds, according to China’s Xinhua news agency.

The do or die orbital insertion maneuver proceeded precisely as planned at the conclusion of a four and a half day voyage to Earth’s nearest neighbor.

China’s ‘Yutu’ lunar lander is riding piggyback atop the four legged landing probe during the history making journey from the Earth to the Moon.

The critical engine burn placed Chang’e 3 into its desired 100 kilometer (60 mi.) high circular orbit above the Moon’s surface at 5:53 p.m. Friday, Beijing Time (4:53 a.m. EST).

An engine failure would have doomed the mission.

Chang’e 3 is due to make a powered descent to the Moon’s surface on Dec. 14, firing the landing thrusters at an altitude of 15 km (9 mi) for a soft landing in a preselected area called the Bay of Rainbows or Sinus Iridum region.

The Bay of Rainbows is a lava filled crater located in the upper left portion of the moon as seen from Earth. It is 249 km in diameter.

The variable thrust engine can continuously vary its thrust power between 1,500 to 7,500 newtons, according to Xinhua.

The lander is equipped with terrain recognition equipment and software to avoid rock and boulder fields that could spell catastrophe in the final seconds before touchdown if vehicle were to land directly on top of them.

The voyage began with the flawless launch of Chang’e 3 atop China’s Long March 3-B booster at 1:30 a.m. Beijing local time, Dec. 2, 2013 (12:30 p.m. EST, Dec. 1) from the Xichang Satellite Launch Center, in southwest China.

If successful, the Chang’e 3 mission will mark the first soft landing on the Moon since the Soviet Union’s unmanned Luna 24 sample return vehicle landed nearly four decades ago back in 1976.

Chang’e 3 targeted lunar landing site in the Bay of Rainbows or Sinus Iridum

The name for the ‘Yutu’ rover – which means ‘Jade Rabbit’ – was chosen after a special naming contest involving a worldwide poll and voting to select the best name.

‘Yutu’ stems from a Chinese fairy tale, in which the goddess Chang’e flew off to the moon taking her little pet Jade rabbit with her.

The six-wheeled ‘Yutu’ rover will be lowered in stages to the moon’s surface in a complex operation and then drive off a pair of landing ramps to explore the moon’s terrain.

Yutu measures 150 centimeters high and weighs approximately 120 kilograms.

The rover and lander are equipped with multiple cameras, spectrometers, an optical telescope, radar and other sensors to investigate the lunar surface and composition.

Chang’e 3 marks the beginning of the second phase of China’s lunar robotic exploration program.

The lander follows a pair of highly successful lunar orbiters named Chang’e 1 and 2 which launched in 2007 and 2010.

The next step will be an unmanned lunar sample return mission, perhaps by 2020.

China’s Chang’e 3 probe joins NASA’s newly arrived LADEE lunar probe which entered lunar orbit on Oct. 6 following a similarly spectacular night time blastoff from NASA’s Wallops Flight Facility in Virginia.

The entire flight sequence proceeded flawlessly and placed the combined Chang’e 3 lunar landing vehicle and ‘Yutu’ rover on the desired earth-moon transfer orbit following spacecraft separation and unfurling of the life giving solar panels and landing legs, announced Zhang Zhenzhong, director of the Xichang center.

“The Chang’e probe is on its way to the moon, of course, is a symbol of China’s national prowess,” said Zhang Zhenzhong through a translator during the live CCTV broadcast. “Of course, it’s a symbol of China’s national power and prowess.”

The three stage 55 meter (185 foot) tall Long March-3B carrier rocket was uniquely equipped with a quartet of strap on liquid fueled boosters to provide the additional liftoff thrust required for the four day journey to Earth’s Moon.

The name for the ‘Yutu’ rover – which translates as ‘Jade Rabbit’ – was chosen after a special naming contest involving a worldwide poll and voting to select the best name.

‘Yutu’ stems from a Chinese fairy tale, in which the goddess Chang’e flew off to the moon taking her little pet Jade rabbit with her.

The Chang’e 3 lander will fire thrusters to enter lunar orbit on Dec. 6.

It is due to make a powered descent to the lunar surface on Dec. 14, firing thrusters at an altitude of 15 km (9 mi) for touchdown in a preselected area called the Bay of Rainbows or Sinus Iridum region.

If successful, the Chang’e 3 mission will mark the first soft landing on the Moon since the Soviet Union’s unmanned Luna 24 sample return vehicle landed nearly four decades ago back in 1976.

‘Yutu’ is sitting atop the 4 legged landing probe during the launch and voyage to the Moon.

A complex maneuver will be used to deploy the six-wheeled ‘Jade Rabbit’ rover. It will be lowered in stages to the moon’s surface and then drive off a pair of landing ramps to explore the moon’s terrain.

Watch this short CCTV news report with a cool animation showing how the ‘Yutu’ rover reaches the lunar surface.

‘Jade Rabbit’ measures 150 centimeters high and weighs approximately 120 kilograms.

The rover and lander are equipped with multiple cameras, spectrometers, an optical telescope, radar and other sensors to investigate the lunar surface and composition.

One highly anticipated highlight will be when the lander and deployed Jade Rabbit rover image each other on the surface.

The rover is expected to continue operating for at least three months.

The Chang’e 3 landing mission marks the beginning of the second phase of China’s lunar robotic exploration program.

It follows a pair of highly successful lunar orbiters named Chang’e 1 and 2 which launched in 2007 and 2010.

Chinese ‘Jade Rabbit’ Rover Aims For The Moon On Sunday

If all goes well, expect another moon robot very soon. The Yutu (“Jade Rabbit”) rover will lift off from China as a part of the Chang’e-3 mission — target launch date Sunday (Nov. 29) — to explore the moon’s Sea of Rainbows after its scheduled landing two weeks later, Dec. 14.

There are other spacecraft orbiting the moon — including the newly launched LADEE from NASA, which is checking out the moon’s tenuous atmosphere — but if this mission succeeds, it would be the first soft landing since Russia’s Luna-24 in 1976. That’s a 37-year drought.

Recent English information on the mission is scarce, but it’s been widely reported that the mission will include a lander in a six-wheeled rover. This Chinese news agency notes that planners expect to put up an astronomical telescope, test remote control between the moon and the Earth, and explore areas around the landing location. You can also read (dated) background information on the mission on the Chinese National Space Administration’s website.

The European Space Agency (ESA), meanwhile, released a press update describing how people from its organization will help track the mission during its journey to the moon. The Europeans will be helping the Chinese track the mission all the way to the time it is expected to reach the surface. After the mission lands, ESA will use two antennas to perform a measurement intended to figure out — “with extreme accuracy”, the agency says — where the lander is located.

And for those who remember, a fun bit of history from 1969 recalled by the Planetary Society: during Apollo 11, the first manned mission to land on the moon, this ground-to-moon exchange actually happened:

Capcom: Roger. Among the large headlines concerning Apollo this morning, there’s one asking that you watch for a lovely girl with a big rabbit. An ancient legend says a beautiful Chinese girl called Chang-o has been living there for 4,000 years. It seems she was banished to the Moon because she stole the pill of immortality from her husband. You might also look for her companion, a large Chinese rabbit, who is easy to spot since he is always standing on his hind feet in the shade of a cinnamon tree. The name of the rabbit is not reported.

Buzz Aldrin, slated to be second man on the moon: Okay. We’ll keep a close eye out for the bunny girl.

Bazinga: Mysterious Earth Orbiting Asteroid Turns Out to be Space Junk

The launch of Chan'ge-2 with 3rd stage (arrowed) now known as 2010 Q (Credit CALT).

Can’t find asteroid 2010 QW1 in the Minor Planet Database? No, the “Men in Black” didn’t secretly remove this Earth-orbiting asteroid from the listing… but recent top-notch detective work by astronomers did.

The mystery of this object all started back on August 23^rd of this year, when the PanSTARRS sky survey based on the summit of Haleakala on the island of Maui in Hawai’i spotted an asteroid that was given the provisional designation of 2013 QW1.

The object was in a wide-ranging orbit around the Earth, leading astronomers to wonder if it was a naturally captured asteroid or perhaps space debris from a previous launch. Either solution to the dilemma would be fascinating. Our large Moon keeps the Earth pretty well swept clear of debris, though a “second Moon,” however small, would be an interesting find. And if 2013 QW1 were to prove artificial, it just might be a piece of history.

The European Space Agency’s NEO Coordination Centre decided to take up the challenge. A call went out to track and observe the 2013 QW1, and a team led by Elisabetta Dotto of INAF-Observatorio di Roma & Maria Barucci & Davide Perna of the Observatoire de Paris managed to get time on the Italian Telescopio Nazaionale Galileo based at La Palma to obtain a spectrum of the object.

“It was a bit of a challenge, because the object was moving fast with respect to a typical NEO,” said Dr. Perna in a recent ESA press release.

The team used an instrument known as DOLORES to make the crucial measurements. DOLORES stands for the Device Optimized for LOw RESolution. The spectrum obtained in the early morning hours of August 25^th shows something much brighter than your typical asteroid, but is characteristic of a painted metallic object.

And thus, 2013 QW1 was removed from the ledger of NEO asteroids maintained by the IAU Minor Planet Center (MPEC). And the leading suspect? The third stage booster of a Chinese Long March 3C rocket that launched the Chang’e 2 spacecraft from Xichang, China on October 1^st, 2010.

Chang’e-2 entered lunar orbit 8 days after launch, and departed on June 8^th of the following year after studying and mapping the Moon. Chang’e-2 then went on to become the first spacecraft to directly reach the L2 Lagrange point 1.5 million kilometres beyond Earth from lunar orbit. The spacecraft also made the first flyby of NEO asteroid 4179 Toutatis on December 13^th of last year. The probe is estimated to continue functioning into 2014, and will be used to hone China’s ability to track objects in deep space.

The NORAD tracking identification assigned to the 3^rd stage booster that launched Chan’ge-2 is 2010-50B.

This sort of discovery is not without precedent.

The launch of Apollo 12, with the 2nd stage arrowed. (Credit: NASA). — The launch of Apollo 12, with the 3rd stage (arrowed) would one day be “asteroid Joo2E3”. (Credit: NASA).

On September 3^rd, 2002, amateur astronomer Bill Yeung discovered an asteroid tentatively designated J002E3. Subsequent studies revealed that the asteroid had a spectrum consistent with that of titanium oxide paint, a decidedly unasteroid-like coating for a space rock to sport. This was, however, a common veneer in use during the Apollo era, and it is now known that J002E3 is the S-IVB third stage booster that launched the second mission to land men on the Moon on November 14^th, 1969. Unlike other boosters, such as the one that launched Apollo 14, the Apollo 12 3^rd stage did not impact the Moon as part of seismic experiments. After a brief period as a “pseudo-moon” of the Earth, J002E3 was kicked out into solar orbit in June 2003 and may return to our neighborhood once again in the 2040s.

NASA’s Lunar Reconnaissance Orbiter has documented the lunar crash sites of these historic boosters. It’s of note that the Apollo 10 Lunar Module Snoopy remains discarded out in solar orbit as well, having been used as a dress rehearsal for the historic Apollo 11 landing. Apollo 10 never landed on the Moon. Efforts have been made by UK astronomer Nick Howes to recover it as well.

And there are more relics of the Space Age awaiting discovery. One of the first things we always check in the case of a pass by a newly discovered NEO closer than the Moon to the Earth is its history, to see if it matches up with any launches headed out beyond Earth orbit in the past.

And the upcoming Mars launches of MAVEN and India’s Mars Orbiter Mission in October & November will be the first to depart Earth orbit since 2011. These will give future generations of asteroid hunters new human-made space hardware to ponder.

The B612 Foundation’s asteroid-hunting Sentinel Space Telescope will also “up the game,” scouting for asteroids from a vantage point interior to the Earth’s orbit. Sentinel is slated for launch in 2016 atop a SpaceX Falcon 9 rocket.

And no, the fabled “Black Knight” satellite of UFO conspiracy buffs’ dreams is nowhere to be found.

What other fascinating relics of the Space Age lie are out there in the solar system, waiting to tell their tale?

China’s Shenzhou-10 Crew Returns to Earth

Screenshot showing the Shenzou-10 capsule on the ground following a successful mission for China.

China successfully completed its longest human space mission as the Shenzhou-10 spacecraft and its crew of two men and one woman returned safely to Earth. The return capsule landed via parachute at 8:07 am local time (0007 UTC) Wednesday, June 26, 2013 on the grasslands of north China’s Inner Mongolia region. The 15-day “Divine Vessel” mission is part of the Chinese space program’s objective of building a permanent space station by 2020.

In the video below, enthusiastic applause comes when the parachute deploys and at other milestones of the return. The crew was quickly greeted and a smiling Nie Haisheng, the commander of the mission, emerged from the capsule first, and was followed by female astronaut Wang Yaping, and crewmember Zhang Xiaoguang.

“At this moment what I most want to say is that space is our dream and our motherland is forever our home,” Nie said. “I wish our motherland to thrive even more and our people to become happier and happier. I thank the entire nation for their concern and support for us.”

During the mission, the Shenzou spacecraft docked with China’s orbiting space module Tiangong-1 in tests intended to prepare for the building of the space station. The crew also spoke via video to school children in China, showing how different objects behave in zero-G. The crew conducted several experiments and medical tests while in space. The official mission duration was 14 days 14 hours and 29 minutes.

This was China’s fifth manned space mission since 2003. China plans to launch the Tiangong-2 space lab around 2015, according to the official Chinese Xinhua news agency, quoting Wang Zhaoyao, director of China’s manned space program office. He said there are plans to put an experimental core module of a space station in orbit in 2018, with the manned space station itself being built around 2020.

Besides building a space station, China also hopes to send astronauts to the Moon.

Amazing Shots! Shenzhou-10 Docked to Tiangong-1, Transiting the Sun

As soon as you see these images, you’ll probably guess who the photographer is … yes, Thierry Legault. He had less than half a second to capture these incredible shots of the Shenzhou-10 module docked to Tiangong-1 Chinese station transiting across the Sun, and it he did it not only once, but twice, on two consecutive days. Can you see the tiny spacecraft among the sunspots? And keep in mind, there are three taikonauts in these images as well, as the Shenzou has been docked to the Chinese space station module since June 11!

The Tiangong-1 space station is just 10.4 meters (34.1 ft) in length, while the Shenzou 10 is 9.25 meters (30.35 ft) long. This top image is a crop of a full-face view of the Sun, (see the full-face view on Thierry’s website) taken with white light filters by Thierry from southern France on June 16, just after noon UTC. The transit duration was just 0.46 seconds, and Thierry calculated the distance of the spacecraft to observer was 365 km away, and the spacecraft was traveling at 7.4km/s (26,500 km/h or 16,500 mph).
He used a Takahashi TOA-150 refractor, Baader Herschel prism and Canon 6D (1/4000s, 100 ISO).

Below is another solar transit of the two Chinese spacecraft, also taken from Southern France, but the next day, June 17, 2013 at 12:34:24 UTC. This one, in Hydrogen-alpha shows the Shenzhou-10/Tiangong-1 complex in multiple shots over the 0.46 second transit.

For this image, Thierry used his Takahashi FSQ-106, Coronado SM90 double stack, camera IDS CMOSIS 4Mp sensor at 38 fps.

This isn’t the first time Thierry has trained his cameras on the Tiangong-1 – in May of 2012 he captured the tiny space station alone transiting the Sun, and it was dwarfed by a huge sunspot sported by the Sun at the time.

In a previous interview with Universe Today, Thierry explained how he prepares to take images like these:

For transits I have to calculate the place, and considering the width of the visibility path is usually between 5-10 kilometers, but I have to be close to the center of this path,” Legault explained, “because if I am at the edge, it is just like a solar eclipse where the transit is shorter and shorter. And the edge of visibility line of the transit lasts very short. So the precision of where I have to be is within one kilometer.”

Legault studies maps, and has a radio synchronized watch to know very accurately when the transit event will happen.

“My camera has a continuous shuttering for 4 seconds, so I begin the sequence 2 seconds before the calculated time,” he said. “I don’t look through the camera – I never see the space station when it appears, I am just looking at my watch!”

He uses CalSky to make his calculations and figure out the timing.

Congrats to Thierry and our thanks to him for sharing his amazing images and skills with Universe Today!

‘Space Class’ Among Aims of Chinese Taikonauts Who Left Earth Today

Riding atop a fiery Long March rocket, three taikonauts blasted off from Earth today (June 11) to kick off an expected 15-day mission in space that will include the first Chinese “space class” from orbit.

Shenzhou 10 departed the Jiuquan Satellite Launch Center at 5:38 a.m. EDT (9:38 a.m. UTC), or 5:38 p.m. local time at the complex’s location in the Gobi desert. Aboard the spacecraft were one woman (Wang Yaping) and two men (Nie Haisheng and Zhang Xiaoguang). Their next destination is the Chinese Tiangong-1 station.

China has a young manned space program. The first spaceflight with people was just a decade ago, in October 2003, and this is the fifth crewed mission since that time.

While China’s government keeps its long-term ambitions fairly private, observers in the United States and China point to its robotic moon missions as evidence that China is considering a manned lunar mission in the coming decades.

Shenzhou 10’s ultimate destination, however, is the Earth-orbiting, nine-ton Tiangong-1. Like the early U.S. and Soviet space stations, the Chinese one is fairly small (a single module) and serves as an experimental testbed for space station work. Taikonauts also visited the space station during Shenzhou 9 in 2012.

The taikonauts have four main ambitions during the Shenzhou 10 mission, the China Manned Space Engineering government office stated:

– Launch crew and cargo aboard Shenzhou 10 and verify rendezvous and docking technology for the meeting with Tiangong-1;

– Further test Tiangong-1’s capabilities to support humans;

– Conduct several experiments (focusing on space adaptability, space operation ergonomics and unspecified space science work), perform maintenance and do a “space class” with students;

– To see how well the CMSE is performing on a systems basis.

“To further improve the safety, reliability and to be suitable for the specific requirements of this mission,” stated spokesperson Wu Ping, “partial technical alterations have been made in [the] Shenzhou 10 spaceship and Long March 2F Y10 rocket.

“During this mission,” she added, “taikonauts will change and repair some of the equipment and facilities in Tiangong-1 through on-orbit operations.”

In the first few hours after launch, the CMSE stated that all systems are performing normally.

“The Shenzhou 10 spaceship has accurately entered its orbit and the crew members [are] in good condition,” stated Zhang Youxia, chief commander of China’s manned space program.

The mission drew praise from China’s president, Xi Jinping, who sent the crew good wishes just before they left Earth.

“You have made Chinese people feel proud of ourselves,” Xi told the crew, according to a BBC report.

“You have trained and prepared yourselves carefully and thoroughly, so I am confident in your completing the mission successfully. I wish you success and look forward to your triumphant return.”

China ultimately plans to launch a larger space station sometime around 2020, which would include several modules.

The European Space Agency is considering working more closely with China around that time, the BBC added, and some astronauts have already starting Chinese language training.

China’s Shenzhou-9 spacecraft and its three-member crew has returned to Earth with a jarring, rolling ground landing in Inner Mongolia at 10:05 local time (02:05 GMT). While in space, the crew successfully carried out their 13-day mission, accomplishing a manual docking with the Tiangong-1 laboratory module and performing a series of experiments. The crew included the first Chinese woman in space, 33-year-old female fighter pilot Liu Yang, along with commander Jing Haipeng, and Liu Wang.
