Gee Plus

Adapting to a High RPM Environment

The Experiment

A 9 meter radius, rotating long-duration space habitat simulation on Earth, simulating 1.4 gees at 10 RPM. 1.4 gees is the vector sum of 1 gee horizontal and 1 gee vertical. Experimental subjects with BMI < 20, having a "gravitational BMI" < 28 but the same "metabolic BMI".

Postulates

(1) Humans evolved to run, hence may be optimized for > 1 gee
- see work by Joan Vernikos, NASA Ames (retired)
- zero gee causes rapid "aging"
(2) The human vestibular system can adapt to high RPMS
- Experiments with rotating rooms show 6 RPM adaptation in 3 days, 10 RPM in 5 days
- Experiments with rotating tube beds suggest 30 RPM ( ! ) adaptation for head movements
- Athletes undergo much faster head rotations

Goals

(1) Test the Vernikos theory: do healthy humans do better in > 1 gee environments?
(2) Learn about long term vestibular adaption, and the transition from rotation to non-rotation
- test frequent transitions through the hub to 1 gee and 0 RPM
(3) Select astronauts for vestibular tolerance for rotating habitats in microgravity
(4) Make low BMI rotonauts into heros

Math

a=981gee = 2R = T22R = 42RT2 T in seconds
