Last Published:  11/23/20 11:55:12 AM (Central)
Short Title: Phase 2 Physics
Responsible HRP Element: Space Radiation
Collaborating Org(s):
Funding Status: Completed - Task completed and produced a deliverable
Procurement Mechanism(s):
Directed
Aims:
Implement Phase II Measurements and Physics Project with light ion focus to develop space radiation transport codes capable of predicting primary and secondary spectra of space radiation environment interaction behind typical spacecraft shielding, planetary surfaces, and atmospheres with increased accuracy. Supply configuration managed V&V'ed source code to radiation user community including Exploration, RHO, and Operations as well as industry partners (e.g. Lockheed Martin) or commercial entities. Current exploration vehicle requirements specify that HZETRN shall be utilized by the government for radiation requirement verification. Transport codes directly support verification of NASA STD 3001 Vol. 2 requirements.

Phase 2 focus:
  • Current focus is on light ion and neutron transport and production including 3-D effects of neutron backscattered and inclusion of dose received from pion production
  • Future nuclear physic improvements will focus on improved models needed for definition of Mars Surface Environment
Implementation of Phase 2 Physics supports closing the following gaps: with improved models and transport to improve estimates/reduce uncertainty of light ion and neutron production and transport through spacecraft materials and secondary environments on the lunar and Mars surface.
