Kosmos 482, a Soviet era spacecraft that decidedly did NOT succeed in its 50+ year-old mission to reach Venus. Now, against the odds, it’s on track for a stunning comeback to Earth. This piece of historic space debris is expected to re-enter the atmosphere around May 10th, plus or minus a few days. Its strange path has drawn international attention, raising questions about what its re-entry could mean. Kosmos 482 had a mass of about 480 kilograms and a size of roughly one meter. It was an instrumental piece of the Venera program, meant to gather valuable information about Venus.
Kosmos 482 still launched in 1972 and would be a risky alternate, as its orbit is in grave peril. Its maximum extent has recently dropped below 400 kilometers, down from almost 10,000 kilometers in the 1970s. The interplanetary space probe has now officially split into four distinct pieces. Specialists do not exclude that the rest of the object is its landing module. Built to endure the harsh conditions of Venus’s carbon-dioxide-rich atmosphere, this module now faces the challenge of re-entry into Earth’s atmosphere.
The Journey of Kosmos 482
Kosmos 482 on-boost to mission on Venera program. Their goal was nothing short of deciphering the mysteries behind Venus, an enigmatic hellish world. While it never accomplished what it was designed to do, the little spacecraft has continued in orbit for three decades. Over the years, its orbit has steadily worsened, raising alarm over a future uncontrolled and dangerous re-entry.
Marco Langbroek, a prominent expert in space debris, reinforces that Kosmos 482 will very likely land in an ocean. In fact, he thinks this outcome is the most likely one. After all, about 71% of our planet’s surface is covered by water! Because of that, the likelihood is very small for it to be close to where people live.
“While not without risk, we should not be too worried,” – Marco Langbroek
The risk posed by Kosmos 482’s re-entry is similar to that of uncontrollable random meteorite falls, which happen multiple times a year. Langbroek emphasizes that individuals face a greater chance of being struck by lightning over their lifetime than being impacted by debris from Kosmos 482.
Potential Risks and Precautions
The re-entry of Kosmos 482 raises issues of safety and the presence of hazardous materials. Dr. J.L. Gorman, a space safety researcher and expert in space sustainability, emphasized the importance of not downplaying debris that could potentially fall to Earth.
“Don’t touch it, because sometimes there are toxic elements,” – Dr. Gorman
If you discover any portion of Kosmos 482 has landed on populated terrain, Dr. Gorman implores you to immediately file a claim. Write to the Australian Space Agency immediately! For example, The U.S. agency will start to directly lobby the Russian government. This is key, as Russia still maintains ownership of de-orbited objects according to international treaties such as the Outer Space Treaty.
“They can’t pretend it’s not theirs this time,” – Dr. Gorman
The worry over space debris has increased as more and more new objects fill Earth’s orbit. Dr. Gorman cautions that space junk will only continue to increase in number moving forward. This increasing threat has led to a demand for better control and mitigation measures.
“There is going to be a lot more [space junk] in the future,” – Dr. Gorman
The Future of Space Debris Management
As humanity ventures further beyond the confines of Earth, the problem of space debris becomes increasingly timely and critical. Kosmos 482 illustrates the impact of missions conducted long ago. Beyond just being a great story of perseverance, it underscores the need for better protocols in space exploration.
Increasingly, experts are emphasizing the need for international cooperation and clear, enforceable guidelines to reduce the risks posed by space debris even further. Kosmos 482’s reentry could be dangerous in several ways. It presents us with an opportunity to really think about and re-shape our existing practices for missions to space.
