seasoned Russian cosmonaut Oleg Kononenko has returned to Earth after a phonograph recording - cave in year - long ride out onboard theInternational Space Station(ISS ) . The 60 - yr - old spaceman has now spent 1,111 non - consecutive daylight in celestial orbit , which is longer than any other cosmonaut in history — and will likely remain unconquered for many age .
Kononenko , who twist 60 in June , render to Earth inside Russia ’s Soyuz MS-25 ballistic capsule on Monday ( Sept. 23 ) , alongside fellow astronaut Nikolai Chub andNASAastronaut Tracy Caldwell Dyson , agree to Live Science ’s sister siteSpace.com . The ternary touched down in the steppe of Kazakhstan around 3.5 hours after undock from the ISS .
Oleg Kononenko has just returned from a 374-day stay on the ISS. In this photo, taken Sept. 15 2023, the cosmonaut prepares to launch on this record-breaking mission.
The two astronaut , or Russian astronauts , had spent a record - breaking 374 continuous days onboard the quad station , narrowly beat NASA astronaut Frank Rubio who inadvertentlycompleted a 371 - daylight stay on the ISS last yearafter his yield craftsmanship was damaged . Dyson , meanwhile , returned after spend 184 Clarence Shepard Day Jr. in space .
Kononeko firstbroke the record for most cumulative days in spacein February , when he surpassed the 878 - sidereal day draw of compatriot Gennady Padalka , who place the disc in 2015 . Kononeko has flown on five different delegation to the ISS since 2008 , which is how the spaceflight veteran racked up his impressive total .
" Thanks to all my crewmates for your friendship . It has been a expectant metre and delight to work and expend fourth dimension together here as a large family on card theInternational Space Station , " Kononenko Saida he was leaving the ISS . " in good order now I am get out my 2nd place . "
The Soyuz MS-25 lander carrying Kononenko, Chub and Dyson touched down in the steppe of Kazakhstan on Monday (Sept. 23).

During his cumulative time in space , Kononenko has completed roughly 17,800 trips around Earth and spend more than 44 hours in the emptiness of space across seven unlike spacewalks .
To put these numbers into perspective , Kononeko is single - handedly responsible for around 1.5 % of thetotal clock time spent in space by more than 600 masses , since the first human space flight was accomplished by Kononeko ’s compatriot Yuri Gagarin in 1961 .
The Soyuz spacecraft detached from the ISS around 3.5 hours before the astronauts touched down on Earth.
One disk that Kononenko has not beaten during his stellar career is the longest uninterrupted stay in space , which is held by Valeri Polyakov , who spend 437 days on Russia ’s former Mir space station between 1994 and 1995 .
During Kononeko ’s most recent sojourn , 14 different ballistic capsule go far at the ISS , includingBoeing ’s infamous Starliner rocket , whichrecently returned to Earth without astronautsafter suffering multiple helium escape . NASA astronauts Butch Wilmore and Suni Williamshave been stranded in spaceas a result , and the latter has justtaken over bid of the ISS from Kononenko .
It is unclear whether or not Kononenko will make any more trips into space . He has not yet announced his retirement but has previously admit that spaceflight is " becoming more complicated " and that train for foreign mission " has not become loose " over time .
But even if he does strike out soon , his record will likely stand up for a long sentence as the next 10 astronauts on the list of most cumulative days in space are either inactive or stagnant .
The next participating astronaut on the listing is Russia ’s Sergey Prokopyev , who has spent 567 non - consecutive days in space , but it is improbable that he will break the phonograph record beforeRussia fully withdraws from the ISS by 2025 . However , spaceman will likely visitChina’srecently make out Tiangong infinite stationin the time to come as part of the two countries’joint mission to make a basis on the moon by 2035 .

An American is unlikely to get around Knononeko ’s record before theISS is deorbited and doss down back to Earth in 2030 , largely because NASA does not generally allow its astronauts to stay in space as long as Russian astronaut .
For Kononenko , his phonograph recording is a nice achievement but has not been the prime motivation for his foresightful lasting career . " I wing into space to do my favorite thing , not to set records , " he suppose in February after breaking the cumulative spaceflight platter .
