Going interstellar

Q: What does the future look like for space exploration—where are we heading next?

"In October 2024, NASA will launch the Europa Clipper spacecraft to explore Jupiter's icy moon. Its scientific objectives include assessing Europa's habitability and understanding its composition. We've always been keen to understand our universe, but it's not always about discovering or exploring new bodies; it's often about gaining a deeper or more accurate understanding of something as we develop new theories and better instruments. We've had spacecraft looking at Europa since the 1970s, but this mission will investigate it with a suite of nine groundbreaking instruments."

Q: Imagine the year 2040. What do you predict will be the biggest breakthrough in your field?

"I'm hopeful that by 2040, we will have returned samples from Mars. The Perseverance rover has already collected over a dozen samples of rock, gas and regolith, so once the samples are retrieved and opened in special labs here on Earth, I have no doubt we'll be amazed by what we find. I suppose we're all holding out hope that we'll see signs of ancient microbial life, but any new scientific discovery about Mars would be worth it. Since one of my roles was designing the sample tubes, I'd love to revisit my old hardware in a museum in 2040."

Q: As a member of the Mars 2020 Mission Team, you said you were living your dream by having helped build something that lands on Mars. What is your next big dream project?

"I'm really excited about the upcoming VERITAS mission to Venus, with an expected launch year of around 2030. Venus is a unique planet in that it could have been like Earth at one time, but has curiously become highly geologically active and inhospitable to life. I've been following this mission since it was proposed about nine years ago, which shows how long it takes to get these projects off the ground. Often, planetary scientists spend their whole careers championing a particular project, and it's a crowning achievement to see it operate in space. As an engineer, I'm lucky enough to join in for the last five years, and then jump to the next project!"
