On February 4, Oleg Kononenko (59) officially spent 879 days in space cumulatively. This Russian astronaut overtook the record held by Gennady Padalka who spent 878 days, 11 hours, 29 minutes and 48 seconds in space. Kononenko is currently on his fifth mission to the ISS after first visiting it in 2008.
The record held by Kononenko is expected to remain for a long time as he is only scheduled to return to earth on September 23. If no issues occur, he will return to earth after spending 1,110 days in space.
Valeri Polyakov, also a Russian cosmonaut holds the record for the longest continuous stay in space. He spent almost 438 days in the Mir spacecraft in 1995. The mission of staying in space for a long time was carried out by Russia to see its effects on the human body. As we have previously reported, among the detected impacts is the shrinking of the brain's white matter and the destruction of 54% more red blood cells than on earth.
