Meteorological support team ready for securing Chang'e-6 return mission

The meteorological team from the Jiuquan Satellite Launch Center has been stationed at the Siziwang Banner landing site of north China's Inner Mongolia Autonomous Region a month in advance to prepare for the landing of the Chang'e-6 return capsule and provide meteorological support for the mission.

Siziwang Banner features a north-to-south elevation gradient, contributing to a higher frequency of severe convective weather events during summer. This year, coupled with the presence of cold air systems in the northern regions, conditions are unusually active.

According to meteorological records, the Siziwang Banner landing site has experienced 16 precipitation events and 13 occurrences of strong winds so far this month.

If strong winds or intense rainfall occur during the landing of the return capsule, it is possible that helicopters from the aerial search and rescue team may be unable to take off. Similarly, ground team may face challenges reaching the landing site promptly due to road damage caused by the weather.

To enhance precision in meteorological support, the meteorological team has compiled and analyzed over seven million pieces of meteorological data from the past decade. They are particularly utilizing transit radars to conduct climate background analysis on potential occurrences of severe convective weather.

"The weather radar can monitor severe convective weather within a radius of 150 kilometers, effectively supplementing the absence of weather radar products in surrounding areas. Through continuous 24-hour real-time monitoring, it can detect the occurrence, development, and changes in severe convective weather. This capability allows for effective monitoring of thunderstorms, heavy rain, strong winds, and other weather conditions, providing crucial data and decision-making support to our frontline command centers," said Shi Jianping, a staff member from Jiuquan Satellite Launch Center.

In addition to the impacts of thunderstorms, rainfall, and surface-level winds, the accurate prediction of upper-level wind direction and speed directly affects the ability of search and recovery teams to successfully locate their target.

If the wind speeds are too high, there is a significant risk that the return capsule may deviate from its projected landing point or drift outside the designated landing area, thereby increasing the difficulty of the search operation. "Once the return capsule deploys its parachute, it enters a state of passive descent, susceptible to influence from high-altitude winds that may cause deviation in its landing spot. It is crucial to incorporate high-altitude wind data into our forecasting models to predict the landing location accurately. Precise forecasting of high-altitude winds can assist our ground and air teams in locating the return capsule more efficiently," said Kang Lin, another staff member from Jiuquan Satellite Launch Center.

After the moon-Earth transfer and separation of the orbiter and returner, the returner is expected to land with lunar samples at Siziwang Banner in north China's Inner Mongolia Autonomous Region as planned.

The Chang'e-6 probe, comprising an orbiter, a lander, an ascender and a returner, was launched on May 3. Its lander-ascender combination touched down at the designated landing area in the South Pole-Aitken Basin on the Moon's far side on June 2, and completed sampling in two days.

Japanese seek diversified investment options as yen devalues

2024-07-14 12:04 Last Updated At:12:37

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.
