A deep rumble followed by an orange cloud spreading over rooftops in a Chinese village has become a recurring phenomenon in recent years, according to reports. These events are linked to launches of Long March rockets from inland sites, which use toxic propellants developed during the Cold War. The fuels, known as UDMH and nitrogen tetroxide, are highly poisonous and have led to evacuations in regions like Hunan and Guizhou. Unlike other spacefaring nations that typically use coastal launch sites to direct debris into the ocean, China's inland launch facilities increase the risk of rocket debris falling near populated areas. The Long March 2, 3, and 4 rockets, which have been in use for decades, rely on these storable propellants. UDMH is used as fuel, while nitrogen tetroxide acts as an oxidizer—both substances are highly corrosive and can cause serious health issues if inhaled or touched. In 2023, a Long March 3B rocket booster crashed near a home in Hunan, and in Guizhou, a similar incident saw a rocket stage fall close to a village, with thick orange smoke observed in the air. These incidents highlight the potential dangers posed by the use of these fuels in populated areas. China has been working on more advanced and less toxic rocket launchers since the 2000s. However, the older rocket models remain in service due to cost-effectiveness and the availability of existing infrastructure. While the United States has largely phased out these propellants, Russia continues to use nitrogen tetroxide in its Proton rocket. The ongoing use of these fuels in China, combined with the country’s inland launch sites, has raised concerns about the health risks faced by nearby communities. Despite efforts to modernize its space program, China's transition away from toxic propellants is still in progress. Rural communities near launch sites continue to experience the unintended consequences of the country's space ambitions. While technological advancements may eventually reduce these risks, the current reliance on older, hazardous fuels underscores the complex trade-offs involved in maintaining a robust space program.
