53 Years Later: The Long-Awaited Crash of a Soviet Venus Spacecraft Back to Earth!

A 53-year-old Venus probe, which never quite made it to its intended destination, is set for an uncontrolled reentry into Earth’s atmosphere in the coming weeks. This spacecraft, built to endure extreme heat, might survive the descent and crash back on Earth.

Marco Langbroek, a satellite tracker in Leiden, Netherlands, predicts that the lander module from a Soviet mission will reenter during the second week of May. “Since this lander was designed for Venus’ harsh environment, there’s a chance it could hit Earth intact,” he noted in a recent blog update. He also added that while the risks aren’t high, they’re not nonexistent.

The spacecraft, called Kosmos 482, launched on March 31, 1972, from Kazakhstan’s Baikonur Cosmodrome. The mission sought to reach Venus but fell short, lacking enough velocity to break free of Earth’s orbit due to an engine malfunction. NASA notes that the craft broke apart into four pieces shortly after launch, with some fragments reentering over New Zealand just two days later. The remaining parts now orbit the Earth at a distance of about 130 by 6,089 miles (210 by 9,800 kilometers).

In total, the mission included a carrier bus and a lander probe, weighing over 1,000 pounds (495 kilograms). Langbroek compared the risks of its reentry to that of a meteorite impact, emphasizing that while concern exists, it’s manageable.

As for the exact timing of the reentry, Langbroek estimates it around May 10. However, it’s hard to be certain. The Sun’s current active phase is warming up Earth’s atmosphere, increasing drag on orbiting objects and potentially speeding up their descent.

The landing site of the spacecraft’s debris remains uncertain, influenced by the timing of its reentry. While it’s unlikely to fall over populated areas, the unpredictable nature of uncontrolled reentries can be concerning. In fact, past events show that most debris usually lands in remote areas or oceans, but public awareness of such incidents is crucial.

In recent years, the topic of space debris has gained attention, especially as the number of satellites in orbit rises. According to a 2022 report from the European Space Agency, there are over 36,500 pieces of space junk currently in orbit around Earth. This adds to the ongoing discussions about space sustainability and safety.

As we observe Kosmos 482’s reentry, it reminds us of the historical challenges and risks involved in space exploration, while also highlighting the advancements in technology that allow us to track and predict such events. Keeping a close eye on these developments not only engages public interest but also reinforces the need for responsible practices in our increasingly crowded orbital environment.
