Q&A
summary
Answers report no alien sightings and describe a visceral perspective shift on Earth while spacewalking, plus a concrete perseverance story: rejected three times and medically disqualified for eyesight, then vision training fixed eyesight and led to selection. Current work focuses on student-led NASA projects and robotics and on hard problems — radiation protection, partial-gravity habitats, in‑situ food production — and notes astronaut applications jump from about 6,000 to 18,000.
