Answering Key Questions About Lunar & Martian Crop Growth

Q: What’s the math behind the lettuce growth?
The lettuce doubles steadily—each week, biomass increases by 20%, meaning it multiplies by 1.2. Starting at 2.5 kg, after 5 weeks:
2.5 × (1.2)^5 = 2.5 × 2.48832 ≈ 6.2 kg

Q: Why round to the nearest tenth?
Rounding ensures clarity and focuses on meaningful precision, balancing scientific rigor with accessible communication—critical for Discover audiences scanning info quickly.

Q: Can this process scale?
Modern data supports scalability; controlled environments significantly boost yield efficiency, especially in resource-limited settings. Long-duration missions and climate-vulnerable farms show promise for tactical crop expansion.
