Landing of Chang'e-6 lunar probe assisted by advanced optical systems

The successful return to Earth of China's Chang'e-6 lunar probe on Tuesday was made possible by advanced optical equipment deployed and monitored by scientists from the Jiuquan Satellite Launch CenterEquipped.

The Chang'e-6 probe successfully returned to its predesignated landing spot in Siziwang Banner, north China's Inner Mongolia Autonomous Region, bringing back the first ever lunar samples from the little-explored far side of the moon. The probe was launched on May 3 for a 53-day mission.

High-definition cameras and sensors installed at the landing site enabled scientists to monitor the probe's return, capturing images of every critical moment and transmitting them back to the command center in real time.

"We have deployed seven optical devices around a five to seven kilometer radius from the landing site, which can achieve point measurement within a 7-kilometer range centered on the aiming point and scene measurement within a 20-kilometer range. After the measurement equipment is installed, back-end operators remotely control the equipment and obtain the entire scene from the launch of the parachute to the landing of the returner 10 kilometers away," said An Xueguang, part of the team operating the optical devices.

The team has successfully helped track return capsules from previous Shenzhou manned space missions but had not operated in Siziwang Banner, which is affected by fast changing weather and wind patterns, for four years.

"The Chang'e-6 return capsule is one-eighth the size of the manned capsule, which is a great challenge for our target acquisition mission. Secondly, the Chang'e-6 return capsule, an unmanned capsule, descends two to three times faster than the manned capsule. So, it is a big challenge to provide stable visual tracking of the capsule during our mission," said Jia Peng, another member of the team at the landing point.

Since it started operations at the landing site, the team has been refining its plans, simulating the most complex possible environments for training, and coordinating the construction of radar, optical, communication and other equipment to ensure that the landing was monitored in real time.

Japanese seek diversified investment options as yen devalues

The Japanese people are eyeing diversified investment options at a three-day wealth management exhibition which started on Friday in Tokyo, as the depreciation of their fiat currency yen goes on.

Since July, the retail price of gold in Japan has repeatedly hit new highs, and the price per gram rose to 13,612 yen (about 86 U.S. dollars) on Thursday.

As inflation continues in Japan, precious metals are increasingly popular as a way to beat it.

In addition to paper gold, rare precious metal coins have gradually become one of the new financial investment favorites in Japan in recent years.

"The gold content of coins determines their value as precious metals. But as collectibles, their price on the auction market will go up," said Mitsuru Hayama, an exhibitor.

In addition to traditional financial products which include real estate, there is a trend of diversification at this exhibition.

For example, for investment products such as agricultural blueberry gardens and mushroom farms, investors can choose to make investment only, or they can participate in specific business operations.

Investable wines and whiskies are also a big draw at the expo. Among them, wine investment has an online trading model, where investors can view the latest prices of wines on their mobile phones in real time and conduct transactions .

"You buy it when it's cheap and drink it whenever you want. This is the prime pleasure of investing in the wine. Even if you don't drink it yourself, you'll be happy if its price rallies," said Eiji Odawara, an exhibitor.

According to the latest data released by the Bank of Japan in June, as of the end of March this year, the scale of Japanese household financial assets inched up 7.1 percent compared with the same period last year, reaching 2,199 trillion yen (about 13.9 trillion U.S. dollars), hitting record highs for five consecutive quarters.

Among them, cash and deposits accounted for 50.9 percent, much higher than other advanced economies such as the United States and some European countries.
