According to him, this mission will take more than eight months.

"It's going to be more than eight months of flying to Mars, then you have to stay there and come back later," Duffy said.

At the same time, he called these plans critically important and added that the experience of flying to the moon would be crucial to ensure that astronauts could live during the mission.

Earlier, Duffy said that the United States plans to land on the moon before the end of the term of American President Donald Trump. russian.rt.com.
