Airless Space Weathering Duplicated in Lab Environment
Tucson AZ (SPX) Sep 04, 2015
Using laboratory instruments typically used to make semiconductor devices, space weathering of airless bodies in the Solar System has been simulated, allowing researchers to better determine the ages of their surfaces, states a new paper by Kimberly R. Kuhlman of the Planetary Science Institute. "'Space weathering' is a catch-all term for what happens to surfaces exposed to the environment of space over time. This includes the micrometeorite impact damage and redeposition, effects of UV radiation, ... read more
