The failed Soviet spacecraft Kosmos 482 will conclude its roughly 50 - year excursion through Earth ’s sphere this weekend , with experts augur it could crash back to our planet as before long as tonight ( May 9 ) .
The latest predictionsfrom theEuropean Space Agency(ESA ) reveal that the Kosmos 482 Descent Craft is poised to reenter Earth ’s air at approximately2:26 ante meridiem EDT ( 06:26 GMT ) on Saturday , May 10 . The uncertainty for the prediction is positive or minus 4.35 hours , giving us an estimated reentry window of roughly10 p.m. EDT Friday ( May 9 ) to 7 a.m EDT Saturday , according to ESA .

Kayhan Space , a Colorado - ground distance technology company that ’s also been tracking the trade , predicts an even narrower reentry windowpane . At mechanical press prison term , the company’slatest estimatepredicts a reentry time of 2:28 a.m. ET ( 6:28 GMT ) on May 10 , plus or minus 2.4 hours .
" The atmospheric density in the lower altitudes ( 50 to 300 klick ) [ 30 to 185 miles ] is very uncertain , which can result in large prediction uncertainties , " Derek Woods , senior astrodynamics engine driver at Kayhan Space , tell Live Science in an email .
Where will Kosmos 482 land?
fall like a meteor through the atmosphere , the or so 3 - fundament - wide ( 1 metre ) , 1,091 hammer ( 495 kg ) craftcould hit virtually anywhere on the planet . It could down at any point between52 academic degree north and 52 arcdegree to the south — an tremendous swath of the satellite that includes almost every major populated area — according to ESA .

Luckily , the odds are irresistibly in party favor of the ballistic capsule landing in the ocean , as most uncontrolled space junk reentry do . expert wo n’t be capable to narrow down the landing zone until minute before the reentry happens , due to the somewhat unpredictable effects of atmospheric drag .

The likelihood of the out - of - control spacecraft hitting a soul is " the usual one - in - several - thousand chance " associate with fall space debris , Jonathan McDowell , an astrophysicist at the Harvard - Smithsonian Center for Astrophysics , wrote in ablog post .
What is Kosmos 482?
The Kosmos 482 probe was build and launched in 1972 as part of the Soviet Union ’s Venera mission to explore Venus . The Soviets successfully launched the Venera 7 and 8 probe , which were the first two spacecraft to successfully land on Venus in 1970 and 1972 , respectively .
Kosmos 482 was progress as a sister probe to Venera 8 . However , due to a malfunction with the Soyuz rocket that set in motion it into space , the probe give out to achieve enough speed to reach Venus , alternatively getting stuck in an ovoid , or ellipse - mold , reach around Earth for more than 50 years — until now .
Designed to survive a fiery fall through Venus ' aura , the Kosmos 482 Descent Craft is likely to stay in one piece as it crashes to Earth this weekend , Marco Langbroek , a lecturer in infinite situational awareness at Delft Technical University in the Netherlands who first discovered the lander ’s at hand retort , write in ablog post . It will be traveling at approximately 150 mph ( 242 km / h ) .
Recent satellite images of Kosmos 482 suggest it may have already deployed its parachute in space several years ago. However, this can’t be proven until reentry begins.
Part of a larger problem
While its intriguing history has earned the lander media attention , Kosmos 482 is just one of more than 1.2 million patch of space junk in Earth ’s arena larger than 0.4 inches ( 1 centimeter ) , according to anESA reportpublished in April .

Orbital collisions and uncontrolled reentries are becoming progressively common , with " inviolate satellites or rocket trunk … now re - entering the Earth atmospheric state on average more than three clock time a day , " according to the ESA report .
The bombastic pieces of space rubble hail from a range of a function of spacecraft , rockets and boosters that are big enough to survive reentry and arrive at the ground .
" We ’re seeing a raise in reentry involving bombastic objects that can partially survive and reach the control surface , " Woods said . " Some of these larger objects are defunct space wash - era objects like KOSMOS 428 DESCENT CRAFT . These object were in highly eccentric orbits and are now naturally decaying after decades in space . "
As the number of new orbiter in Earth ’s orbital cavity increases every year , it will become more important than ever for missions to have " controlled end - of - life plans for large objects " and for outer space government agency to invest in debris remotion technology , Woods add up .
