Sure, Matt Damon gets marooned on Mars in his new sci-fi drama The Martian and George Clooney has no easy space-ride in Gravity, but which of Damon’s movie astronaut brethren is most deserving of NASA’s top prize?

According to the 45-year-old actor, that honor would go to Matthew McConaughey, who bravely raced to save all of humanity in last year’s extraterrestrial thriller, Interstellar.

“It’s a tough one but I feel that Matthew gets the blue ribbon,” Damon tells PEOPLE in this week’s issue.

“George just got himself killed off so quickly – even though it was a noble death, he was still out of there in the first act – but Matthew hung in there and showed a lot more fortitude, so I’d have to vote for him.”

To tap into his own inner fortitude and make it in space, Damon says he’d need a few key belongings, including a playlist loaded with U2 and The Beatles, the Complete Works of William Shakespeare (“a lot of bang for your buck”) and a stockpile of pasta with meatballs.

Most important, he adds: “I’d need to have a picture of my wife and four daughters.”
