China’s Chang’e-5 robotic moon lander is due to spend only two days collecting samples of lunar rock and soil before it sends its shipment on its way back to Earth, but it’s making the most of the time.

Just hours after landing on December 1st, the probe started using its robotic scoop and drill to dig up material at Mons Rümker, a lava dome in a region called Oceanus Procellarum, or the Ocean of Storms.

It’s also been sending back pictures and video, including this stunning view of the final minutes before touchdown. Watch how the camera tips straight down to focus on the target spot for the lander:

For the third time in seven years, a Chinese robotic spacecraft has landed on the Moon — but now things will get really interesting: If the Chang’e-5 mission succeeds, the probe will deliver fresh samples from the Moon to Earth for the first time in 44 years.

Chang’e-5’s paired lander and ascent vehicle touched down in a lunar region known as Oceanus Procellarium, near Mons Rümker, at 1513 UTC (11:13 p.m. Beijing time) December 1st. The landing came eight days after the 9-ton spacecraft was launched from Wenchang Space Launch Center, and three days after the craft settled into lunar orbit.

China aims to land a science probe and research rover on the far side of the Moon by 2020, say Chinese officials.

Chinese scientists plan to carry out the highly complex lunar landing mission using a near identical back up to the nations highly successful Chang’e-3 rover and lander – which touched down in December 2013.

If successful, China would become the first country to accomplish the history making task of a Lunar far side landing.

“The mission will be carried out by Chang’e-4, a backup probe for Chang’e-3, and is slated to be launched before 2020,” said Zou Yongliao from the moon exploration department under the Chinese Academy of Sciences, according to a recent report in China’s government owned Xinhua news agency.

Zou made the remarks at a deep-space exploration forum in China.

“China will be the first to complete the task if it is successful,” said Zou.

Chinese space scientists have been evaluating how best to utilize the Chang’e-4 hardware, built as a backup to Chang’e-3, ever since China’s successful inaugural soft landing on the Moon was accomplished by Chang’e-3 in December 2013 with the mothership lander and piggybacked Yutu lunar rover.

Plans to launch Chang’e-4 in 2016 were eventually abandoned in favor of further evaluation.

After completing an intense 12 month study ordered by China’s government, space officials confirmed that the lunar far side landing was the wisest use of the existing space hardware.

Chang’e-4 will be modified with a larger payload.

“Chang’e-4 is very similar to Chang’e-3 in structure but can handle more payload,” said Zou.

“It will be used to study the geological conditions of the dark side of the moon.”

The moon is tidally locked with the Earth so that only one side is ever visible. But that unique characteristic makes it highly attractive to scientists who have wanted to set up telescopes and other research experiments on the lunar far side for decades.

“The far side of the moon has a clean electromagnetic environment, which provides an ideal field for low frequency radio study. If we can can place a frequency spectrograph on the far side, we can fill a void,” Zou elaborated.

China will also have to launch another lunar orbiter in the next few years to enable the Chang’e-4 lander and rover to transmit signals and science data back to Chinese mission control on Earth.

In the meantime, China already announced its desire to forge ahead with an ambitious mission to return samples from the lunar surface later this decade.

The Chinese National Space Agency (CNSA) plans to launch the Chang’e-5 lunar sample return mission in 2017 as the third step in the nations far reaching lunar exploration program.

“Chang’e-5 will achieve several breakthroughs, including automatic sampling, ascending from the moon without a launch site and an unmanned docking 400,000 kilometers above the lunar surface,” said Li Chunlai, one of the main designers of the lunar probe ground application system, accoding to Xinhua.

The first step involved a pair of highly successful lunar orbiters named Chang’e-1 and Chang’e-2 which launched in 2007 and 2010.

The second step involved the hugely successful Chang’e-3 mothership lander and piggybacked Yutu moon rover which safely touched down on the Moon at Mare Imbrium (Sea of Rains) on Dec. 14, 2013 – marking China’s first successful spacecraft landing on an extraterrestrial body in history, and chronicled extensively in my reporting here at Universe Today.

A Chinese robotic probe has just successfully completed the first round trip to the Moon and back home in four decades that paves the path for China’s next great space leap forward – an ambitious mission to return samples from the lunar surface later this decade.

On Saturday, Nov. 1, the unmanned Chang’e-5 T1 test capsule nicknamed “Xiaofei” concluded an eight-day test flight around the Moon by safely landing in Siziwang Banner of China’s Inner Mongolia Autonomous Region, according to a report by the official Xinhua News agency.

China thus become only the third nation to demonstrate lunar return technology following the former Soviet Union and the United States. The Soviet Union conducted the last lunar return mission in the 1970s.

Search teams with helicopters recovered the “Xiaofei” orbiter intact at the planned landing zone about 500 kilometers away from Beijing.

The Chang’e-5 T1 test mission is an unequivocally clear demonstration of China’s mounting technological prowess.

Chang’e-5 T1 served as a technology testbed and precursor flight for China’s planned Chang’e-5 probe, a future mission aimed at conducting China’s first lunar sample return mission in 2017.

“Chang’e-5 is expected to collect a 2-kg sample from two meters under the Moon’s surface and bring it home,” according to Wu Weiren, chief designer of China’s lunar exploration program.

The ability to gather and analyze pristine new soil and rocks samples from the Moon’s surface would be a boon for scientists worldwide seeking to unlock the mysteries of the solar system’s origin and evolution.

“Xiaofei” was launched on Oct. 23 EDT/Oct. 24 BJT atop an advanced Long March-3C rocket at 2 AM Beijing local time (BJT), 1800 GMT, from the Xichang Satellite Launch Center in China’s southwestern Sichuan Province.

It was boosted on an 840,000 kilometer, eight-day mission trajectory that swung halfway around the far side of the Moon and back. It did not enter lunar orbit.

During its path finding journey, “Xiaofei” captured incredible imagery of the Moon and Earth, eerie globes hanging together in the ocean of space.

The probe was developed by the China Aerospace Science and Technology Corporation. The service module is based on China’s earlier Chang’e-2 spacecraft.

On its return, the probe hit the Earth’s atmosphere at around 6:13 a.m. Saturday morning at about 11.2 kilometers per second for reentry and a parachute assisted soft landing in north China’s Inner Mongolia Autonomous Region.

The goal was to test and validate guidance, navigation and control, heat shield, and trajectory design technologies required for the sample return capsule’s safe re-entry following a lunar touchdown mission and collection of soil and rock samples from the lunar surface – planned for the Chang’e-5 mission.

“To help it slow down, the craft is designed to ‘bounce’ off the edge of the atmosphere, before re-entering again. The process has been compared to a stone skipping across water, and can shorten the ‘braking distance’ for the orbiter,” according to Zhou Jianliang, chief engineer with the Beijing Aerospace Command and Control Center.

“Really, this is like braking a car,” said Zhou, “The faster you drive, the longer the distance you need to bring the car to a complete stop.”

China hopes to launch the Chang’e-5 mission in 2017 as the third step in the nation’s ambitious lunar exploration program.

The first step involved a pair of highly successful lunar orbiters named Chang’e-1 and Chang’e-2 which launched in 2007 and 2010.

The second step involved the hugely successful Chang’e-3 mothership lander and piggybacked Yutu moon rover which safely touched down on the Moon at Mare Imbrium (Sea of Rains) on Dec. 14, 2013 – marking China’s first successful spacecraft landing on an extraterrestrial body in history, and chronicled extensively in my reporting here.

China’s space officials are currently evaluating whether they will proceed with launching the Chang’e-4 lunar landing mission in 2016, which was a backup probe to Chang’e-3. Although Yutu was initially successful, it encountered difficulties about a month after rolling onto the surface which prevented it from roving across the surface and accomplishing some of its science objectives.

China is pushing forward with plans to start building a manned space station later this decade and considering whether to launch astronauts to the Moon by the mid 2020s or later.

Meanwhile, as American lunar and planetary missions sit still on the drawing board thanks to visionless US politicians, China continues to forge ahead with no end in sight.
