Space Calc
Doing the math, so you don't have to.


Space Calculators is primarily developed by Ian Mallett, a Computer Science Ph.D student with an additional background in Physics and Math.

All calculators are validated against real-world data when available, sanity-checked when not. However, radiation burns, rocket crashes, etc. stemming from e.g. misuse of (or errors in) these resources are not my responsibility. In-particular, these calculators are for non-safety-critical use (and you are reminded of this on particularly dangerous calculators).

Some calculators are adapted/improved from third-party sources. These are credited on those pages.

Feel free to contact me with suggestions for new calculators, or if you'd like to help! You can also
