LRO CRaTER Highlighting Dangers Of Space Environment

CRaTER1014

Data From CRaTER Instrument Aboard LRO Orbiter Demonstrating Impact Of Abnormal & Extended Lack Of Solar Activity; Since 2006 – Longest Solar Minimum / Weakest Solar Activity Is Bringing About Highest Intensities Of Galactic Cosmic Rays Witnessed Since Beginning Of Space Age Says CRaTER PI Nathan Schwadron Of UNH; Trend Reducing Allowable Days For Human Deep Space Exploration By 20%; Lunar Exploration – Short Transit & Possibilities For Underground Habitation – More Feasible Than Deep Space / Mars Exploration With Current Technology
