Questions & Answers

Q: How did the astronaut feel after his two-week space flight compared to the 200-day mission?

The astronaut felt exhilarated after the two-week flight but craved more challenges, while the 200-day mission left him feeling fulfilled yet ready to move on to new pursuits.

Q: What was the recovery period like after returning from each space mission?

The recovery after the two-week flight was quick, with initial dizziness and heaviness of sensations improving within a day or two. In contrast, the 200-day mission had a more challenging recovery period, with initial discomfort and orthostatic intolerance symptoms.

Q: How did the astronaut maintain bone density and muscle strength in space?

The astronaut followed a strict exercise regimen including weightlifting, treadmill, and bike sessions for two and a half hours each day, focusing on resistive exercises to combat bone density loss in space.

Q: Can you explain how the vacuum resistance exercise machines work in space?

The workout machine, known as RED, uses vacuum instead of air compression for resistance, with tubes and cylinders providing up to 600 pounds of force. The machines are designed to avoid damaging the space station's structure during high-impact exercises.
