Next week, the Earth will experience a unique event as a defunct Soviet spacecraft descends uncontrollably into our atmosphere. The Kosmos 482 mission, which launched in 1972, was initially designed to reach Venus. However, due to a malfunction during its launch, it never left Earth’s orbit. Astronomers have tracked the spacecraft and predict its re-entry will occur around May 10.
Details on the exact time and location of the spacecraft’s landing remain uncertain, as well as the quantity of debris that might survive the journey through the atmosphere. Nevertheless, experts assert that while there is some minimal risk, the general public should not be overly concerned.
Uncontrolled re-entries pose challenges due to their unpredictability, potentially resulting in debris striking buildings, vehicles, or people. Previous incidents have seen space debris land in various locations, from a yard in Poland to Florida homes and the ocean, even showering metal over Côte d’Ivoire.
China has faced criticism from the U.S. for allowing components of its Long March rockets to re-enter Earth’s atmosphere uncontrollably. NASA emphasizes the importance of responsibly managing space debris and sharing information on the paths of falling objects to ensure safety on the ground.
In the case of the Soviet spacecraft, its initial objective was to reach Venus, making its descent more of an unfortunate accident than a sign of negligence. The probe’s construction, which was intended to withstand the harsh conditions of Venus, suggests that parts of it may survive re-entry and impact the Earth’s surface. It is housed in a spherical titanium pressure vessel, rendering it both heavy and durable.
“This heat shield implies that the half-ton sphere, about one meter in diameter, might very well endure atmospheric entry and strike the ground,” explains orbital expert Jonathan McDowell. “It has a low but existent chance of hitting someone. Though it is dense and inert, it contains no nuclear material, so there’s no significant cause for alarm, but you wouldn’t want it to collide with you.”
This assessment is echoed by Marco Langbroek, a researcher in space situational awareness, who highlighted the spacecraft’s origins and noted that while risks are quite low, they still exist. “Given its mass of just under 500 kg and size of one meter, the risks posed are reminiscent of a meteorite impact,” Langbroek stated.
