Soviet-era spacecraft plunges to Earth after 53 years stuck in orbit

Soviet-era spacecraft plunges to Earth after 53 years stuck in orbit

A Soviet-era spacecraft plunged to Earth on Saturday, more than half a century after its failed launch to Venus.
Its uncontrolled entry was confirmed by the Russian space agency Roscosmos and European Union Space Surveillance and Tracking. The Russians indicated it came down over the Indian Ocean, but other experts were uncertain of its location. The European Space Agency's space debris office tracked the spacecraft's doom after it failed to appear over a German radar station.
It was not immediately known how much, if any, of the half-ton spacecraft survived the fiery descent from orbit. Experts said ahead of time that some if not all of it might crash to Earth, given that it was built to withstand a landing on Venus, the solar system's hottest planet.
The chances of anyone getting hit by spacecraft debris were exceedingly low, scientists said.
Launched in 1972 by the Soviet Union, the spacecraft known as Kosmos 482 was part of a series of missions bound for Venus. This one never made it beyond orbit around Earth, stranded there by a rocket malfunction.
Much of the spacecraft came tumbling back to Earth within a decade of the failed launch. No longer able to resist gravity's tug as its orbit dwindled, the spherical lander — an estimated 3 feet across — was the last part of the spacecraft to come down. The lander was encased in titanium, according to experts, and weighed more than 1,000 pounds.
Any surviving wreckage will belong to Russia under a United Nations treaty.
After the spacecraft's downward spiral, scientists, military experts and others could not pinpoint in advance when or where the spacecraft might come down. Solar activity added to the uncertainty, as did the spacecraft's deteriorating condition after so long in space.
After so much anticipation, some observers were disappointed by the lingering uncertainty over the exact whereabouts of the spacecraft's grave.
'If it was over the Indian Ocean, only the whales saw it,' Dutch scientist Marco Langbroek said via X.
As of Saturday afternoon, the U.S. Space Command had yet to confirm the spacecraft's demise as it collected and analyzed data from orbit.
Space Command routinely monitors dozens of reentries each month. What set Kosmos 482 apart — and earned it extra attention from government and private space trackers — was that it was more likely to survive reentry, according to officials.
It was also coming in uncontrolled, without any intervention by flight controllers who normally target the Pacific and other vast expanses of water for old satellites and other space debris.

What to know: Second SpaceX launch of doubleheader in Florida set for overnight hours

SpaceX is ready for its second Florida launch in less than 24 hours − as a Starlink mission is set to lift off during the overnight hours. The liftoff is set for no earlier than 1:29 a.m. July 2 from Launch Complex 40 at Cape Canaveral Space Force Station. Backup opportunities exist until 5:28 a.m. This mission comes just after SpaceX successfully launched the MGT-S1 weather satellite for the European Space Agency at 5:04 p.m. on July 1. With this launch, SpaceX is going for another record-breaking booster landing, as it continues to push reusability of its fleet of first stage boosters. The Falcon 9 booster flying this mission will be seeing its 29th flight. It remains to be seen how many flights SpaceX can get out of a single Falcon 9 booster. The mission, known as Starlink 10-25, is the latest batch of SpaceX's Starlink internet satellites. The Falcon 9 rocket will launch 27 satellites, which will join more than 7,000 Starlink satellites already in orbit. Starlink delivers internet in some of the most remote areas on Earth. Upon liftoff, the rocket will travel on a northeast trajectory. When is the next Florida launch? Is there a launch today? Upcoming SpaceX, Axiom, ULA rocket launch schedule at Cape Canaveral The launch will not sound any Space Coast sonic booms, as just over eight minutes past lift off, the booster will land out on a SpaceX drone ship stationed in the Atlantic Ocean. Check back for live updates beginning 90 minutes prior to liftoff on this page. Countdown Timer Brooke Edwards is a Space Reporter for Florida Today. Contact her at bedwards@ or on X: @brookeofstars.

This supermassive black hole is eating way too quickly — and 'burping' at near-light speeds

When you buy through links on our articles, Future and its syndication partners may earn a commission. Astronomers have witnessed a distant supermassive black hole devouring its surrounding matter so rapidly that it is "burping" out excess mass at nearly a third of the speed of light. The discovery was made when researchers studied the supermassive-black-hole-powered Active Galactic Nucleus (AGN) of a Seyfert galaxy located about 1.2 billion light-years away. The black hole, designated PG1211+143, has a mass around 40 million times that of the sun and powers a bright quasar. This made it a prime target for astronomers seeking to understand how supermassive black holes grow by feeding on, or "accreting," matter. The team examined the black hole using the European Space Agency (ESA) X-ray spacecraft XMM-Newton, finding an influx of matter equivalent to the mass of 10 Earths flowing to the object over a period of just five weeks. The matter falling around the black hole settles into a flattened cloud of gas and dust called an accretion disk, from which material is fed to the central black hole. But even this monstrous black hole can't stomach so much matter, leading to some serious indigestion in the form of outflows travelling at around 0.27 times the speed of light. That's about 181 million miles per hour, or 100,000 times the top speed of a Lockheed Martin F-16 jet fighter. These outflows followed the black hole's inflow of matter with a delay of a few days, heating matter around the AGN to temperatures of several million degrees. This generated radiation pressure that pushed excess matter away from the central region of PG1211+143. Because stars form in galaxies from excesses of cold, dense gas, these high-speed outflows could be starving PG1211+143's surrounding space of the building blocks for new stars, both by heating gas and dust and by pushing that material away. That means studying these high-speed outflows from this black hole could help scientists to discover how black hole eruptions transform galaxies from hubs of star birth to a more quiescent existence.

See Earth's Forests as Never Before in Biomass Satellite's First Images

Just two months after its launch, the European Space Agency (ESA) Biomass satellite is already showing us Earth in a whole new light. On June 23 the ESA released the mission's first images, which showcase its unique capability to peer through dense vegetation to study our planet's forests and other ecosystems as never before. Using cutting-edge radar technologies, the satellite is on a five-year mission to survey forests across sprawling swaths of the globe, looking beneath their canopies to accurately assess their total woody biomass—trunks, limbs, stems, and so on. By measuring all that material and how it's changing over time, scientists can better monitor deforestation trends and track the flow of carbon through ecosystems to enhance our understanding of Earth's rapidly changing climate. The satellite is still in its six-month-long commissioning phase, but now we have a taste of what is to come. The image shown above displays a section of the Amazon rainforest in Bolivia with the Beni River meandering through. Each color represents a different ecosystem feature: black for rivers and lakes, pink for wetlands and floodplains, green for rainforests, and purple for grasslands. The World Resources Institute's Global Forest Review ranks Bolivia among the top 10 countries with the most tree cover loss between 2001 and 2024. During this time, Bolivia lost the equivalent of 15 percent of the total forest cover it had in 2000, in large part to encroaching agricultural plots and cattle ranches. These images and their associated data can help researchers keep careful tabs on deforestation and its impacts on local and global ecosystems. [Sign up for Today in Science, a free daily newsletter] The image below highlights the satellite's power by comparing its observations with those gathered by a Biomass predecessor, ESA's Copernicus Sentinel-2 mission, in the same location. The new pictures represent a significant increase in detail that is primarily owed to Biomass's main instrument: the P-band synthetic aperture radar. P-band radio waves are longer than others more typically used in such radar systems, allowing them to pass through layers of foliage, soil and other materials to create accurate three-dimensional maps of otherwise hidden landscape features. Because of engineering challenges as well as diplomatic ones, this is the first time P-band radar has been used in orbital Earth observations—the P-band radio frequency is typically reserved for American and European missile-detection systems. (In order to ensure it will not interfere with the U.S. Department of Defense's space-object-tracking radar systems, Biomass will not observe North and Central America, Europe, and some Arctic regions.) The next three images below demonstrate just how deep the P-band radar can go. They display topographic features of rainforests in Indonesia, the Sahara Desert in Chad and the Transantarctic Mountains adjacent to the Nimrod Glacier in Antarctica, respectively. Pictured above is Indonesia's mountainous Halmahera rainforest, featuring rugged topography shaped by outpourings from the numerous volcanoes that pockmark the region. One of them, the active volcano Mount Gamalama, can be seen off the coast on the far left. Though the main goal of the Biomass satellite is to catalog forests, it will also study other environments. Above is a portion of the Tibesti Mountains situated in the central Sahara Desert in northern Chad. Able to map features as far as five meters beneath dry sand, the satellite can reveal ancient geologic details, such as dried-up riverbeds and lakes, now buried below the Sahara's ever-shifting dunes. These data can help researchers understand past ecological changes in such regions—and could even help unearth hidden pockets of precious groundwater in arid, remote deserts. Biomass can also penetrate into ice, pictured below, and collect information about ice-sheet structure and movement that could be used to better understand what controls the slide of glaciers into the sea. Below, another image features jungle-covered terrain in Gabon and prominently displays the Ivindo River, which nurtures the surrounding rainforest. The predominantly green color of the image indicates dense vegetal growth—a sign of a healthy rainforest. The final image shown here, below, is the very first one the satellite produced. It displays a portion of the Amazon rainforest in Brazil, highlighting the topography of the region alongside features such as rivers, wetlands and grasslands. Only a small portion of the vast Amazon has been studied in-depth and on the ground. This is largely because of its scale and the associated difficulty of reaching some of its most remote regions. Innovative satellites like Biomass could greatly increase our knowledge of these overlooked places and similar ones around the world, helping researchers better understand—and protect—our changing planet and its myriad beautiful ecosystems.
