Many individuals gazing on the moon shining brightly within the night time sky marvel what secrets and techniques the Earth’s satellite tv for pc holds.

Nonetheless, few of them have the possibility to entry lunar soil and research it to unlock such mysteries, in contrast to Qian Yuqi.

At first of this yr, Qian, a postdoctoral fellow from the Division of Earth Sciences on the College of Hong Kong, or HKU, utilized to entry lunar soil samples from the China Nationwide House Administration. His utility was authorised in June.

It was the primary time Hong Kong had secured lunar soil samples for research.

Though he’s solely 28, Qian, a geologist who wears darkish glasses and sports activities a flat haircut, has been learning the moon for almost a decade.

His enthusiasm for all issues lunar runs deep. His laptop desktop boasts a display saver displaying the moon. He carries a backpack displaying the Chinese language characters for “moon exploration”, and a mannequin of the moon sits on his workplace desk. Qian additionally repeatedly emphasizes simply how attention-grabbing his lunar research are.

Qian’s curiosity in area dates to his childhood. Whereas immersing himself in science fiction movies and novels, he observed that these tales have been at all times set in area, with geologists taking part in vital roles.

After passing the faculty entrance examination in 2013, Qian pursued a level in geology at China College of Geosciences (Wuhan) in Hubei province. He might solely select a significant centered on the Earth’s geology, as no undergraduate applications on the mainland at the moment have been particularly targeted on planetary science or deep area exploration, he mentioned.

Qian labored arduous, as he knew that learning the Earth’s geology might lay a stable basis for exploring different planets. His alternative quickly arrived, with China’s lunar exploration program gaining vital momentum.

In 2004, China formally launched the Chang’e undertaking to discover the moon in three phases to satisfy three goals: unmanned lunar exploration, a manned lunar touchdown, and establishing a lunar base.

The unmanned lunar exploration, or the Chinese language Lunar Exploration Program, additionally consists of three phases: orbiting, touchdown and returning.

The orbiting part, which started in 2004, concerned Chang’e 1 in 2007 and Chang’e 2 in 2010 exploring the lunar floor from orbit. The touchdown part concerned Chang’e 3 in 2013 and Chang’e 4 in 2018 touchdown on the moon’s floor for detailed exploration. The returning part included the Chang’e 5 mission in 2020, which collected lunar samples for a return to Earth.

When the Chang’e undertaking began, many mainland college researchers switched their analysis focus to the moon and have become concerned in these missions.

Analysis position

In Could 2011, Qian’s college established the Planetary Science Institute, with the goal of spearheading analysis in lunar and planetary science.

The institute organized a lecture on the college to current its analysis findings. Qian attended the lecture, discovering it deeply attention-grabbing. That night time, he wrote a letter to a senior professor on the institute, stating that he wished to contribute to furthering China’s area endeavors.

Impressed by Qian’s means and enthusiasm, the professor accepted him as his analysis pupil – giving Qian entry to nationwide lunar analysis.

Beneath his mentor’s steerage, Qian carried out a whole lot of analysis based mostly on knowledge collected by Chang’e 3 and Chang’e 4. He additionally supported a prelaunch research for Chang’e 5.

The Chang’e 5 mission group aimed to pick the most effective touchdown website from a 50,000-square-kilometer preselected zone.

Qian remained in his laboratory for a lot of days, extensively reviewing distant sensing archives of the moon’s floor captured by satellites. He found the jap area of the preselected zone might include basalts which are about 2 billion years outdated – doubtlessly making subsequent soil collections youthful than any earlier samples secured by different nations, similar to america and the previous Soviet Union.

Such samples might present insights into the moon’s formative historical past. Given the similarities between early lunar and Earth environments, this might additionally assist scientists unravel the secrets and techniques of the Earth’s early historical past.

Qian launched a paper suggesting the touchdown website for Chang’e 5, stimulating in depth dialogue amongst scientists and the mission group.

Chang’e 5 was resulting from launch in 2017. Nonetheless, in July that yr, the undertaking skilled a big setback when the Lengthy March 5 giant provider rocket, which is the principle booster of Chang’e 5, didn’t raise off.

Engineers swiftly launched an emergency investigation into the reason for the failure.

This was additionally a distressing time for Qian. “Because the Lengthy March 5 was a essential undertaking, the issue needed to be tackled rapidly. Nonetheless, the timeline was unsure, and I discovered this deeply worrying,” he mentioned.

Whereas intently following information reviews in regards to the Lengthy March 5 and Chang’e 5, Qian continued his doctorate analysis at his college, whereas remaining targeted on lunar research.

The Lengthy March 5 was lastly launched in November 2020, taking Chang’e 5 skyward.

The probe landed exactly the place Qian really helpful, amassing 1,731 grams of samples. As well as, evaluation of the soil confirmed Qian’s analysis. The soil is almost 1 billion years youthful than any earlier lunar volcanic deposits returned to Earth.

Rental alternatives

Since July 2021, the China Nationwide House Administration, or CNSA, Lunar Exploration and House Engineering Middle has granted eligible organizations the chance to hire lunar analysis samples for associated analysis.

Requested by his mentor to analysis some soil samples, Qian rapidly wrote a number of papers about them.

In December, Qian accomplished his doctorate with flying colours. In recognition of his exemplary work, he acquired the Li Siguang Excellent Ph. D. Pupil Award early this yr, one of many highest awards for geoscience college students in China.

Qian subsequent determined to additional his lunar analysis by means of a postdoctoral place in HKU’s Division of Earth Sciences.

Deep area missions similar to lunar exploration demand vital monetary and technological capabilities – sometimes the protect of countries similar to China and america, and the European House Company.

“Doing analysis in Hong Kong affords me the chance to stay engaged in a nationwide undertaking, additional contributing to the nation,” Qian mentioned.

Researching lunar geology in Hong Kong can even stimulate improvement of associated native industries, encourage younger folks within the metropolis to participate on this subject, and improve cooperation between Hong Kong and the mainland on deep area exploration, Qian mentioned.

Students in Hong Kong learning the moon’s geography largely depend on distant sensing knowledge, somewhat than direct evaluation of lunar soil. “I can use my talents to fill a spot on this respect,” Qian mentioned.

After becoming a member of HKU in March – turning into the primary on the establishment to interact in lunar analysis – Qian quickly began to use for lunar soil for his work.

Early this yr, the CNSA once more started accepting purposes for lunar samples, and Qian spent a month making ready a proposal, submitting it earlier than the deadline.

A couple of weeks later, the CNSA phoned him to say his proposal had handed the preliminary evaluate and would now require an oral protection.

On the finish of Could, Qian defended his proposal in Beijing, introducing his analysis concepts, group members, gear for experiments, and pattern storage circumstances at his college to the panel of judges.

Throughout the utility course of, Qian discovered that lunar science within the nation is progressing swiftly. Many prime universities now provide undergraduate applications to domesticate experience in deep area and planetary domains. Their school and college students, together with researchers from key establishments, are making use of to review lunar soil for functions past Qian’s volcanology analysis.

Listing authorised

In June, the CNSA issued the ultimate authorised checklist for borrowing lunar analysis samples. A complete of 60 purposes from 23 people at 16 analysis establishments have been endorsed. In all, simply over 12,328 milligrams of samples have been distributed.

Qian was among the many profitable candidates – acquiring 4 lunar samples with a complete weight of 822.6 mg. He can borrow them for one yr.

On the finish of July, Qian traveled to Beijing to gather the samples, however his journey coincided with the arrival of Hurricane Doksuri.

Regardless of heavy rain attributable to the hurricane, the CNSA ready the samples on time for students – stopping any delays in analysis for these all through the nation who traveled to gather them.

As Qian sat on the practice heading again to Hong Kong, rain poured relentlessly, obscuring the view past his window. As he continued his journey, he learn information on his cellphone of the escalating casualties attributable to the extreme downpours.

Nonetheless, he had no time to fret about his security, as his consideration was firmly targeted on the lunar samples. He rigorously secured the container inside his backpack in shock-absorbing foam. He held the backpack tightly to attempt to shield the samples from each vibration and sway of the practice.

He lastly relaxed solely after his 11-hour journey ended and he was again in Hong Kong safely.

“Securing these samples is a dream come true for ourselves and Hong Kong’s area science neighborhood,” Qian mentioned, including that such acquisition additionally displays the central authorities’s dedication to supporting the town.

By granting his request, the central authorities additionally demonstrated their need to see Hong Kong develop capabilities within the subject of area and preserve tempo with advances made on the mainland, Qian added.

Within the coming yr, Qian mentioned he’ll use the lunar samples to unlock mysteries of the moon’s volcanic historical past, attempt to present insights into its geological previous, and its connection to the formation and evolution of planetary our bodies within the photo voltaic system.

Moreover, he hopes his utility will assist set up a complete mechanism at HKU for storing lunar samples and conducting analysis, thus enhancing the town’s capability to participate in future nationwide lunar exploration missions.

First milestone

Qian mentioned the moon is the primary milestone on humankind’s journey to exploring the cosmos, including that China has many lunar exploration plans for the rapid future.

Chang’e 6, scheduled for launch someday subsequent yr, is about to change into the primary probe to retrieve samples from the darkish aspect of the moon.

In 2026, China plans to launch Chang’e 7 to research water sources on the moon’s south pole. After this, the nation envisions establishing small bases on the moon. Moreover, China is aiming for a manned touchdown on the moon earlier than 2030.

Qian, who’s researching the touchdown website for Chang’e 6, plans to proceed acquiring soil samples introduced again by the probe. He mentioned he may even attempt his finest to change into concerned in future nationwide area missions.

Many individuals in Hong Kong and Macao, similar to Qian, are actively contributing to the nation’s area exploration efforts.

For instance, Macau College of Science and Know-how, or MUST, has been concerned in knowledge evaluation and scientific analysis for the Chang’e undertaking since 2005.It’s the first college within the Guangdong-Hong Kong-Macao Better Bay Space, or GBA, to be concerned within the nation’s lunar undertaking.

On the finish of 2019, the CNSA introduced the institution of an area exploration and science middle on the Macao college to enhance the deep degree of cooperation between the GBA and worldwide analysis institutes by utilizing Macao’s benefits. As well as, Macao Science 1, the primary area science satellite tv for pc collectively developed by the mainland and Macao, was launched this yr.

In the meantime, Hong Kong Polytechnic College, or PolyU, has made noteworthy contributions to growing {hardware} to assist nationwide area exploration efforts.

In 2013, PolyU collaborated with consultants from the China Academy of House Know-how to develop the Digital camera Pointing System. Regardless of working in difficult circumstances, this navigation digital camera was landed on the moon by Chang’e 3 to seize photos of the lunar panorama.

The digital camera was later up to date and used once more in the course of the Chang’e 4 mission in 2018.

Moreover, the PolyU group was accountable for growing the system used to pattern lunar soil collected by the Chang’e 5 probe in 2020.

That yr, PolyU additional efficiently developed and manufactured the Mars Touchdown Surveillance Digital camera, one of many key devices aboard the spacecraft participating within the Tianwen 1 mission – the nation’s first to the Pink Planet.

PolyU additionally carried out an in depth evaluation of the geology and topography of the touchdown zones for the Chang’e 3 and Chang’e 4 missions, supporting the 2 probes to seek out appropriate touchdown websites.

No less than three universities in Hong Kong provide undergraduate and grasp’s diploma applications for coaching aerospace personnel, with 100 graduates specializing in aerospace know-how annually.

In 2020, collection of the nation’s fourth batch of astronauts began, with the method open to candidates from Hong Kong and Macao for the primary time. This month, the method reached the ultimate stage, and included a number of candidates from each cities.

Qian mentioned: “Whereas public consideration typically focuses on rapid issues, scientists look farther into the longer term. Occasions similar to wars, pandemics, local weather crises, or outbreaks of superviruses might render Earth inhospitable to life sometime, and right now’s scientific endeavors will contribute to securing humanity’s residence sooner or later.”
