On January 3, 2019, China made history by becoming the first country to land a spacecraft on the far side of the Moon. This incredible achievement showcased the impressive progress of China’s space program. With the most annual launches and the ability to send humans into space, China is now recognized as one of the top space programs in the world. However, there are some safety concerns about how China conducts its space missions.
China often launches rockets over areas where people live, which has led to incidents where pieces of rockets have fallen into towns and villages. In this article, we’ll explore why China launches rockets over these areas and how they are working on making their rockets safer by developing reusable technology.
During the Cold War, the United States and the Soviet Union were in a race to show off their nuclear weapons and missile technology. In 1957, the Soviet Union launched the first satellite into space, which pushed China to start its own space program. Over the next 20 years, China built three main launch sites for missiles and satellites. These sites were located inland to protect them from enemy attacks, but this meant rockets were launched over places where people lived.
When picking a place to launch rockets, several things are considered. Rockets need to gain a lot of horizontal speed to reach space, so launch sites are usually near coastlines where debris can fall safely into the ocean. Sites closer to the equator are also better because the Earth’s rotation helps rockets use less energy to reach orbit. However, during the Cold War, China chose inland sites further north, which led to safety issues.
In the 1960s and 1970s, China became a major player in space exploration, building powerful rockets and successfully launching and recovering satellites. Unfortunately, in their rush to compete with the U.S. and Soviet programs, safety was sometimes overlooked. A tragic event occurred in 1996 when a Long March 3B rocket crashed into a village, causing fatalities. Despite this, China continued launching rockets over populated areas.
In recent years, there have been reports of rocket debris landing on homes. Many launches happen from the XiChang site, where the Long March 3B rocket drops its boosters before the first stage. Although efforts are made to avoid populated areas, some villages are still in the path. Before launches, the government warns residents to evacuate, turn off power, and seek shelter. The Long March 3B uses hypergolic fuel, which is very toxic, so people must stay away from any debris.
China’s approach to space missions has led to a lack of trust from other countries. Despite having an advanced space program, China is not part of the International Space Station due to fears that it might try to gain technology from other nations.
China is working to change its practice of launching over populated areas. A new launch site has been built on Hainan Island, allowing rockets to launch over the sea. Additionally, China is adding grid fins to some rockets, similar to those on the Falcon 9, to better control their descent. This is likely part of China’s efforts to develop reusable rockets, which could greatly improve safety in their space missions.

On January 3, 2019, China became the first nation to successfully land a spacecraft on the far side of the Moon. This remarkable achievement highlighted the advancements of China’s space program. With the highest number of annual launches and the capability of sending humans into orbit, China is now considered one of the leading space programs globally. However, amidst this success, there are concerns regarding safety standards in China’s space operations.
Rockets are often launched over populated areas, which has led to incidents where debris has fallen into towns and villages. In this video, we will explore the reasons behind China’s decision to launch over inhabited areas and examine how their efforts to develop reusable rockets may address these safety issues.
During the Cold War, the United States and the Soviet Union were in a constant race to showcase their advancements in nuclear weapons and missile technology. In 1957, the Soviets launched the first satellite into orbit, prompting China to establish its own space program to keep pace. Over the next two decades, China developed three main launch sites designed for missile and satellite launches. These sites were built inland to minimize vulnerability to enemy attacks, but this decision resulted in rockets being launched over populated regions.
When selecting launch site locations, several factors are considered. As a rocket ascends, it must gain significant horizontal velocity to reach orbit, which is why launch sites are typically situated along coastlines where falling debris can safely land in the ocean. Additionally, launch sites closer to the equator benefit from the Earth’s rotational speed, requiring less energy for the rocket to achieve orbit. However, during the Cold War, China opted for inland sites further north, which led to safety concerns.
Throughout the 1960s and 1970s, China emerged as a major space power, developing heavy-lift rockets and successfully launching and recovering satellites. Unfortunately, in the rush to compete with American and Soviet programs, safety standards were compromised. A notable incident occurred in 1996 when the Long March 3B rocket veered off course shortly after launch and crashed into a nearby village, resulting in fatalities. Although the disaster was attributed to a fault in the rocket, it did not deter China from continuing launches over populated areas.
In recent years, there have been multiple reports of rocket debris landing on homes. Many of China’s launches occur from the XiChang launch site, where the Long March 3B drops its boosters before the first stage. Despite efforts to target unpopulated areas, there are several villages in the launch path. Prior to launches, the government issues evacuation notices to local residents, advising them to turn off power and seek shelter. Compounding the issue, the Long March 3B uses hypergolic fuel, which is highly toxic, necessitating that residents stay clear of any debris.
While every nation has its own approach to space operations, China’s history has led to a lack of trust from other countries. Despite having a sophisticated space program, China has been excluded from participating in the International Space Station due to concerns that it might exploit the opportunity to acquire technology.
However, China is taking steps to move away from its practice of launching over populated areas. A new launch site has been established on Hainan Island, allowing some of China’s largest rockets to launch over the sea. Additionally, China has begun incorporating grid fins into some of its rockets, similar to those used on the Falcon 9, enabling better control of the rocket’s descent. This development is likely a sign of China’s efforts to create reusable rockets, which could significantly enhance safety in their space operations.
