8. RECENT GCR MODELS COMPARED TO AMS DATA

Recent Alpha Magnetic Spectrometer measurements of the high energy hydrogen and helium spectra have been previously compared with NASA and ESA (European Space Agency) galactic cosmic ray (GCR) codes. The Skobeltsyn Institute of Nuclear Physics (SINP) has recently developed a new GCR code, which is used by the Russian space agency (ROSCOSMOS). This new code is compared to the AMS data and shown...

23. Update on the Worsening Particle Radiation Environment Observed by CRaTER and Implications for Future Human Deep-Space Exploration

Over the last decade, the solar wind has exhibited low densities and magnetic field strengths, representing anomalous states that have never been observed during the space age. As discussed by Schwadron et al. (2014), the cycle 23--24 solar activity led to the longest solar minimum in more than 80 years and continued into the ``mini'' solar maximum of cycle 24. During this weak activity, we...

6. Active Dosimeter-Based Estimate of Astronaut Acute Radiation Risk for Real-Time Solar Energetic Particle Events

Christopher Mertens (NASA Langley Research Center)

Radiation exposure from solar energetic particle (SEP) events becomes a much greater concern as human exploration extends beyond low Earth orbit (LEO) and the protective environment of Earth's magnetic field. Free space SEP events have an increased impact on mission planning and operations, as countermeasures may be necessary to avoid exceeding astronaut permissible exposure limits (PELs) and...
