The head of state said this at a joint press conference with Payette in Lviv on Thursday, an Ukrinform correspondent reports.
"I asked Mrs. Governor General if she has ever been to Ukraine. I received a very interesting answer that this is her first visit to Ukrainian land," Poroshenko said.
According to him, Payette said she wanted to present to him a photo of Ukraine, which she took from outer space.
"I am very pleased to see this fantastic photo. This wasn't a technical satellite photo, this was a photo made with love by the Governor General when she was in outer space," he said.
He also added that the photo would be kept in his presidential office.
