Russian cosman Yuri Malenchenko’s wife has suffered a severe respiratory problem while travelling to Japan and has been placed in intensive care, officials said.
Russian cosmonauts have previously suffered a similar complication in recent weeks when they had to return home due to problems in the recovery process.
In November, Russian cosmologist Yuri Malinchenko returned home from a mission in the International Space Station, where he was treated for severe respiratory problems.
Malinchenko, 52, was taken to the hospital for treatment of his breathing problems on Thursday.
He had not yet returned to the Russian space station when the problems began.
