Soviet spacecraft launched over 50 years ago is heading to Earth
A piece of a Soviet spacecraft launched in 1972 is expected to crash back down to Earth very soon, experts say. The part, which is from the Cosmos 482 probe, was meant to land on the planet Venus.While it made it into space successfully, the spacecraft wasn't able to complete its journey after something went wrong.Most of the remains of the rocket eventually came back to Earth within the 10 years that followed.But one final section, which experts say is the landing capsule or lander module, ended up stuck in space. It's now been there for 53 years.
What exactly happened?
The part of the spacecraft which was supposed to land on Venus was sent to the super hot planet to carry out scientific measurements, scientist Dr Marco Langbroek from Delft University of Technology (TU Delft) explained to Newsround. "The engine of the rocket that launched it stop working too early, so it was left stranded in an orbit around the Earth," he said."It then broke up, with the lander module that was supposed to land on the surface of Venus detaching from the main spacecraft."The main spacecraft, which was large and heavy, burned up in the (Earth's) atmosphere long ago...but the lander module kept orbiting the earth."
What will happen next?
As the landing capsule has been orbiting Earth in space, it has also been steadily falling towards Earth."...Within a few days, it will be so low that it can no longer do a full round around the Earth," Dr Marco told us. It will eventually enter the Earth's atmosphere, slowing down quickly in the process. "It will briefly become very hot, just like a shooting star. It will then fall down to earth, almost vertically," Dr Marco says. He predicts the spacecraft will enter the Earth's atmosphere around the 10 May and that its final speed will be similar to that of "a high-speed train or very fast race car".
It's not yet known whether the piece of the spacecraft will survive its journey back to Earth, or whether it'll burn up as it crashes through the planet's atmosphere. But the risk of anyone or anything getting in the way of the plunging lander module is very low. It could hit the ground, or will most likely enter the sea. "You have a higher risk of being hit by lightning once in your life, than being hit by this falling spacecraft," Dr Marco told us. Although it's unlikely the lander will remain intact, it would have been full of instruments from over half a century ago, something which some experts are intrigued by. "It's almost a bit as if a time capsule is falling to Earth," Dr Marco said.

Sun hiding ‘invisible asteroid threat' as scientists warn Earth risks ‘collision' with ‘highly chaotic' Venus space rock
Click to share on X/Twitter (Opens in new window) Click to share on Facebook (Opens in new window) A FIELD of at least 20 asteroids has been found lurking near Venus, having previously been hidden by the Sun's glare, experts have revealed. The belt of asteroids is currently co-orbiting Venus, swinging around Earth's closest planetary neighbour with differing proximities to our planet. Sign up for Scottish Sun newsletter Sign up 3 A 3D rendered image of Venus, Earth's closest planetary neighbour Credit: Getty Scientists from Brazil have warned that there could be more asteroids hiding near Venus, and that they may even pose a risk to Earth. "Twenty co-orbital asteroids of Venus are currently known," the authors wrote in their study, published in the journal Astronomy & Astrophysics. "Co-orbital status protects these asteroids from close approaches to Venus, but it does not protect them from encountering Earth." Asteroids are considered potentially hazardous asteroids (PHA) if they have a diameter of at least 140 metres and come within 0.05 astronomical units of Earth's orbit, according to experts. "We aim to assess the possible threat that the yet undetected population of Venus co-orbiters may pose to Earth, and to investigate their detectability from Earth and space observatories," the authors wrote. 3 An artist's impression of the Sun's glare from Earth Credit: Getty - Contributor Only one of the 20 known asteroids has an orbital eccentricity below 0.38 - with 0 being a perfectly circular orbit and 1 meaning an elliptical or oval-shaped orbit. This means some asteroids with wider orbits will be easier to spot, but those with minor orbital eccentricities may be difficult to detect. However, Venus asteroids with an orbital eccentricity higher than 0.38 could "pose a collisional hazard to Earth," the researchers warned. Co-orbital asteroids - ones that share an orbit with their nearby planet - are also known for having unpredictable orbits. This makes it harder to figure out how dangerous they are. Cold War era Soviet spaceship that was meant to reach Venus to FINALLY crash back to Earth at 17,000mph "The co-orbital asteroids of Venus are highly chaotic, with Lyapunov times of the order of 150 years," the authors explained. The Lyapunov time refers to how long an object's orbit takes to become unpredictable because of chaotic dynamics. So scientists have no idea how the orbit of an asteroid will evolve over the next 150 years, and if it could collide with Earth in the future. It's unclear how big the Venus asteroids are. But even a relatively small asteroid of 150 meters in diameter could strike Earth with a force equal to hundreds of megatons of TNT, Universe Today reported. For context, that is thousands of times more potent than the atomic bombs dropped in World War 2. The researchers said that more research is required to determine just how many asteroids are hiding near Venus. But since they are only observable periodically due to the Sun's glare, research from Earth's perspective might be difficult - even with powerful telescopes. The researchers suggest, therefore, that the best way to learn more about these hidden asteroids is to get a closer look. "Observations conducted from Venus' orbit, positioned facing away from the Sun, may enhance the detection of these bodies," the researchers explained.

Exact location failed spacecraft hit as it crashed back to Earth after 53 years
Failed Soviet spacecraft Kosmos 482 came crashing back down to Earth after more than half a century in space - and scientists have now confirmed where it ended up The landing spot of a failed Soviet spacecraft that came crashing down to Earth at the weekend has been revealed. Kosmos 482, was launched by the USSR in 1972 and once bound for Venus, but a badly configured timer onboard the probe meant it never left our planet's orbit. Instead, the lander section of the spacecraft spent decades spiralling back towards Earth, catching the eye of space agencies, the US military and astronomers, who monitored it closely. In the last few weeks, experts announced that the spacecraft was due to enter Earth's atmosphere on May 10, and said it could land anywhere between 52 degrees north and 52 degrees south latitude - sparking frenzied speculation as to where it would end up. In the end, Kosmos 482's re-entry to Earth after more than half a century in space went largely unnoticed, and it was initially unclear where it had landed, reports Manchester Evening News. On Saturday morning, the European Space Agency (ESA) revealed that the Kosmos 482 descent craft was not spotted by radar systems over Germany at the time it was expected to pass. The ESA said "it is most likely that the re-entry has already occurred". But later that day, the Russian Space Agency Roscosmos reported: "The spacecraft entered the dense layers of the atmosphere at 9:24 Moscow time [6.24am UK time], 560 km west of Middle Andaman Island, and fell into the Indian Ocean west of Jakarta." Because the lander was designed to withstand entry into Venus' harsh atmosphere, it is possible it survived re-entry, according to NASA. The space agency said Kosmos 482 landed in the ocean west of Jakarta, Indonesia. No damage or injuries were reported, and the lack of any fireball sightings suggests it landed far out to sea - and far away from any populated areas. This was largely in line with astronomers' expectations, and ESA had stated that the "risk of any satellite re-entry causing injury" is "extremely remote." The space agency added: "The annual risk of an individual human being injured by space debris is under 1 in 100 billion. In comparison, a person is about 65,000 times more likely to be struck by lightning." However, it certainly will not be the last man-made structure that comes crashing back to Earth, and the spacecraft's return highlights the growing risk of potentially hazardous space debris orbiting Earth. Kosmos 482 was just one of more than 1.2 million pieces of space debris measuring larger than centimetre in size, according to a report by the ESA. Satellites or rocket bodies are now re-entering the Earth's atmosphere more than three times a day, with orbital collisions and uncontrolled re-entries happening increasingly often.
