New Chinese Lunar Relay Satellite Launches into Space
China’s Next Lunar Relay Satellite Blasts Off: Ensuring Communication Beyond the Moon’s Horizon
Communication between spacecraft relies upon line of site technology, if anything is in the way, communication isn’t possible. Exploration of the far side of the Moon is a great example where future explorers would be unable to communicate directly with Earth. The only way around this is to use relay satellites and the Chinese Space Agency is on the case. The first Queqiao-1 was able to co-ordinate communications with Chang’e-4 landers and now they are sending Queqiao-2 to support the Change’e-6 mission.
If you have ever gazed upon the Moon you might have noticed that it always has the same hemisphere facing the Earth. This phenomenon is known as captured or synchronous rotation. It may look like the Moon isn’t rotating but in reality the time it takes to spin once on its axis is the same as the time it takes to complete one orbit around the Earth, keeping one hemisphere constantly facing us. Explorers on the near side of the Moon have no trouble communicating with transmissions taking just over one second to reach home. Explore the far side of the Moon and you have a problem.
To overcome the problem, China has launched a 1.2-ton communication satellite known as Queqiao-2. Its name originates from the mythological bridge made from magpies. In the Chinese tale, the magpies formed a bridge across the Milky Way to allow the lovers Vega and Altair to be together for one night once a year. Two miniature satellites were also launched, Tiandu-1 and Tiandu-2, from the island of Hainan.
On arrival, Queqiao-2 will orbit the Moon and provide a relay for the Chang’e-6 lander which is slated to launch in May. It will join satellites from the United States, India, and Japan to support the exploration of the far side of the Moon. Chang’e-6 will collect samples from an ancient basin. Not only will it serve the communications for Change-6, but it will also transfer communications for Chang’e-7 and ‘8. Both craft are set to be launched in the years ahead in 2026 and 2028, respectively.
The orbit of Queqiao-2 will take it almost over the south pole in an elliptical orbit. It will reach an altitude of 8,600 km so that communication can be achieved for a little over eight hours. At its closest, it will sweep over the lunar surface at an altitude of 300 km.
The ultimate goal of the Chinese Space Agency is to create a network of satellites, not too dissimilar (but not quite on the same scale) to the growing SpaceX constellation which is building a global internet presence. The purpose of Tiandu-1 and Tiandu-2 is to test the concept of such a constellation.
China’s longer-term aspirations include a research station at the lunar south pole, and for this to be viable, communication relays are essential to establish communication, navigation, and remote sensing.

Is now the right time to invest in gold as prices have cooled?
The price of gold has climbed to record highs recently and has remained strong through much of April. And, that growth continued until the precious metal traded at around $2,390 per ounce on April 19, 2024. But since, growth in the price of the precious metal has cooled, with gold’s price now hovering around $2,300 per ounce.
This lull in gold’s price may represent an investment opportunity.
In general, investing is centered around buying assets when prices are low and selling them when prices are high – generating a profit on the difference between the two. So, considering the declines in gold’s price over the past few days, now may be the time to make your investment. But is buying gold during this lull in prices really a good idea?
Compare your gold investment options among leading brokers now.
Gold prices have cooled. Should you buy in now?
With gold’s price down from recent highs, you may be wondering if now is the right time to buy in. There are several reasons the dip in gold’s price may represent an opportunity to buy. Here are some of the biggest:
Prices may rise again
If looking at a gold price chart shows anything for certain, it shows that changes in the overall growth of the medal come in fits and spurts. Periods of price growth are typically followed by periods of declines and vice versa.
But with inflation rising in recent months – and with gold’s reputation as a safe-haven asset that can hedge against inflation – it only makes sense that the price of the precious metal will eventually start to head up again in the future. While attempting to time that directional change may be tricky, buying the precious metal while the price is down gives you the opportunity to take advantage of any upward movement that may be ahead.
Add gold to your portfolio now before prices have a chance to rise.
You may be able to make a quick profit
Gold isn’t known as an asset in which you can earn a quick return, but in today’s market, that may be the case. Don’t forget that in January, gold was trading at just $2,000 per ounce. And, by mid-April, the commodity’s price had climbed to around $2,400 per ounce. That’s about 20% growth in a matter of months, much of which happened since March 1 – an impressive climb for any investment asset.
Perhaps more importantly, gold’s price growth through the beginning of 2024 shows that the commodity doesn’t have to be a buy and hold style investment that you keep in a safety deposit box or precious metal depository for years to come. There’s also the possibility that the commodity’s price could climb further ahead, making it a compelling way to potentially generate a quick profit.
There are other benefits of investing in gold
There are other benefits of investing in gold that have little to do with the price growth seen thus far in 2024 – or the lull in prices seen over the past couple of days. Those benefits include:
- Inflation protection: Gold has long been considered an inflation hedge, and for good reason. When inflation drives the prices of consumer goods and services up – and the value of the dollar down – gold’s price tends to rise. So, it could be used to maintain the value of your portfolio during inflationary economic conditions. That’s important in today’s economic environment as stubborn inflation continues to weigh on the value of the dollar.
- Portfolio diversification: Gold’s price doesn’t always move in the same pattern that bonds or stocks do. So, mixing a reasonable amount of gold into your portfolio (up to 10% of your portfolio assets) as a diversifier could protect you from losses should one or more of your traditional portfolio assets fall in value. “If you have less than 5% – 10% of your net worth in commodities & FX (forex), you should absolutely consider adding exposure to gold and other precious metals,” says Vijay Marolia, money manager and managing partner at the wealth management firm, Regal Point Capital.
The bottom line
Gold’s price has fallen from recent highs – which may represent an opportunity to tap into growth ahead. However, gold isn’t simply a “buy while it’s low and sell while it’s a high” kind of investment opportunity. The commodity can also protect your portfolio from the stubborn inflation we’ve seen thus far in 2024 while acting as a diversification tool that could increase your risk-adjusted portfolio returns. So, consider adding gold to your portfolio today while it has the potential to grow in value.
