Russian cosmonaut Oleg Kononenko set a world record on Sunday for total time spent in space, surpassing his compatriot Gennady Padalka who logged more than 878 days in orbit, Russia’s space corporation said.
Mr Kononenko broke the record at 0830 GMT (7:30pm AEDT), Roscosmos said.
He is expected to reach a total of 1,000 days in space on June 5, and by late September he will have clocked 1,110 days.
“I fly into space to do my favourite thing, not to set records,” Mr Kononenko told the TASS news agency in an interview from the International Space Station (ISS), where he is orbiting about 423 kilometres from Earth.
“I am proud of all my achievements, but I am more proud that the record for the total duration of human stay in space is still held by a Russian cosmonaut.”
The 59-year-old took the top spot from Mr Padalka, who had accumulated a total of 878 days, 11 hours, 29 minutes and 48 seconds, Roscosmos said.
The Soviet Union spooked the West in the early years of the space race by being the first to launch a satellite to orbit the Earth — Sputnik 1, in 1957 — and then Soviet cosmonaut Yuri Gagarin became the first man to travel into space in 1961.
But after the 1991 collapse of the Soviet Union, Russia’s space program grappled with massive funding shortages and corruption.
Officials under President Vladimir Putin have repeatedly vowed to turn around the decline of Russia’s space programs, though serious problems still remain, according to officials and space analysts.
Life in space no picnic
Mr Kononenko said he worked out regularly to counter the physical effects of “insidious” weightlessness, but it was only upon returning to Earth that he realised how much life he had missed out on.
“I do not feel deprived or isolated,” he said.
“It is only upon returning home that the realisation comes that for hundreds of days in my absence the children have been growing up without a papa. No one will return this time to me.”
He said cosmonauts could now use video calls and messaging to keep in touch with relatives, but getting ready for each new space flight became more difficult due to technological advances.
“The profession of a cosmonaut is becoming more complicated. The systems and experiments are becoming more complicated. I repeat, the preparation has not become easier,” he said.
Mr Kononenko dreamed of going to space as a child, and enrolled in an engineering institute before undergoing cosmonaut training. His first space flight was in 2008.
His current trip to the ISS launched last year as part of the Soyuz MS-24 mission.
The ISS is one of the few international projects on which the United States and Russia still cooperate closely. In December, Roscosmos said that a cross-flight program with NASA to the ISS had been extended until 2025.
Relations in other areas between the two countries have broken down since Russia’s invasion of Ukraine nearly two years ago, to which Washington responded by sending arms to Kyiv and imposing successive rounds of sanctions on Moscow.
