“I told them, ‘Here’s where the will is, here’s where the trust documents are, and if anything happens to me, here’s what’s going to happen to you,’” the NASA astronaut said. “I actually wish more people in everyday life talked to their families in that way because you never know what the next day is going to bring.”

 is now parenting two teenage daughters.

“On behalf of myself, Victor, Christina and Jeremy, we are really pumped to do this.”

Wiseman’s daughters traveled to Florida to watch their father take part in the historic return to lunar flight. While he has kept details about Ellie and Katherine mostly private—only noting that one is in high school and the other in college—he has spoken candidly about their feelings.

He shared that both initially had “zero interest” in seeing him go back to space. “We talked about it, and I said, ‘Look, of all the people on planet Earth right now, there are four people that are in a position to go fly around the moon,’” Wiseman explained. “I cannot say no to that opportunity.” By the next day, however, their perspective shifted. He woke up to homemade moon-themed cupcakes and their support, according to 10 News.

Reid Wiseman shared how difficult is it to leave his daughters behind, noting the intense emotional toll takes on them. “The toughest part is the stress that I’m putting on them,” the NASA astronaut added.

He acknowledged that his mission comes with personal sacrifice. “There’s a very real reason that we still live in Houston,” he told Baltimore Magazine, recalling how his late wife encouraged him to continue pursuing his career even during her illness. “When my wife started getting sick, I wanted to move towards family. But she said, ‘No, this is where you work, and you love your job. And we should not give that up for this.’”

The NASA astronaut added that he wants his daughters to see resilience firsthand. “Also, I want my kids to know that you can still achieve and go on and pick yourself up. I think when I said, ‘This is something that I want to go do, it’s important to me, and I think I can do a good job at this,’ they were aligned very quickly.”

As a personal touch, Reid Wiseman plans to carry letters from his daughters with him on the journey around the moon.
