Calculate a user's age and life expectancy on each planet. Feb 2020.
Inspired by the Sci-Fi Trilogy Remembrance of Earth's Past by Cixin Liu, this site allows users to plan for inter-solar system travel with the fictitious space travel organization, The Halo Group. This Halo Group website will allow their customers to enter their age and how many years they plan to be cryogenically frozen to see how many years old they would be and the difference in their age and their estimated life expectancy on different planets that are part of a travel package.
| Behavior | Input | Output |
|---|---|---|
| User inputs age | -- | error |
| "twenty" | error | |
| User inputs age under 80 | 20 | 60 (years until estimated life expectancy) |
| User inputs age over 80 | 90 | 10 (years past estimated life expectancy) |
| User inputs preferred cryogenically frozen years | 20 | est. life expectancy + 20 |
| User over 80 inputs preferred cryogenically frozen years | 20 | error |
| User selects planet | Mercury | Earth age / .24 |
| 20 | Estimated total years left / .24 | |
| 90 | Estimated years over / .24 | |
| User selects planet | Venus | Earth age / .62 |
| 20 | Estimated total years left / .62 | |
| 90 | Estimated years over / .62 | |
| User selects planet | Mars | Earth age / 1.88 |
| 20 | Estimated total years left / 1.88 | |
| 90 | Estimated years over / 1.88 | |
| User selects planet | Jupiter | Earth age / 11.86 |
| 20 | Estimated total years left / 11.86 | |
| 90 | Estimated years over / 11.86 |
