SN: Why is the Perseverance mission important?
DT: Perseverance is the fifth rover to explore Mars. During the last mission, we discovered that Mars once had water on it and had the right mix of chemicals in its atmosphere to support life. But was there ever life on Mars? With Perseverance, I hope we get to actually answer that question. I think that we are very close.
Another thing we’ve done is fly the first helicopter [called Ingenuity] on another planet. It’s just a really cool way of exploring.
SN: What’s the next step in space exploration?
DT: I expect we’ll continue to explore other planets with robotics and also start bringing humans to these planets so we can see for ourselves. There’s only so much you can do with a rover. It’s not the same as being there.
SN: What do you think about people who aren’t trained astronauts visiting space?
DT: Space is for everybody—not for specific people who have specific degrees. My hope is that eventually anybody can say, “I’m going to take the 5 o’clock shuttle to the moon.” It will be amazing if we get to that point. There’s no reason why we couldn’t.
