    • Analysis of the microstructure of bone affected by Galactic Cosmic Radiation 

      Cavallero, Nicholas J.; Davis, Catherine M.; Lau, Anthony G. (2022)
      With NASA aiming for human exploration missions to deep space and Mars, the dangers of radiation exposure become ever more concerning. Outside of Earth’s atmosphere, astronauts are no longer shielded by Earth’s atmosphere. ...

    • Bone mechanical property changes in rats exposed to Galactic Cosmic Radiation 

      Stibler, Alexandra K.; Davis, Catherine M.; Lau, Anthony G. (2022)
      As NASA prepares to venture deeper into space and increase spaceflight duration, sources of potential harm for astronaut health must be explored. Galactic Cosmic Radiation (GCR), a primary source of radiation from the Milky ...

    • Bone microstructural changes in rat tibias exposed to space radiation 

      Vander Wiele, Sabrina S.; Felipe, Jack T.; Thomas, Patricia; Davis, Catherine M.; Lau, Anthony G. (2021)
      Human health outside of the Earth’s atmosphere has become a greater concern as humans have lived on the International Space station for over 20 years. Radiation poses a risk to astronaut health, yet there is little research ...

    • Bone Strength Changes in Rats Exposed to Proton Radiation 

      Torres, Gilberto; Davis, Catherine M.; Lau, Anthony G. (2020)
      Once outside the Earth’s magnetic field astronauts are exposed to a range of particles that can alter their biological makeup. Exposure to radiation has been shown to increase bone porosity and thus an increased fracture ...

    • Effect of galactic cosmic radiation on bone microstructural strength 

      Felipe, Jack T.; Vander Wiele, Sabrina S.; Davis, Catherine M.; Lau, Anthony G. (2021)
      NASA has been looking into new technology for long duration space flight to Mars. Space travel has many unknowns and dangers that are both visible and invisible. Once outside of Earth's radiation shielding atmosphere, ...

    • The effect of helium ion radiation on the material properties of bone 

      Thomas, Patricia; Sullivan, Lindsay K.; Dickinson, Gary H.; Davis, Catherine M.; Lau, Anthony G. (Springer, 2021-06)

    • The Effects of 4-He Radiation on the Material Properties of Bone 

      Thomas, Patricia; Davis, Catherine M.; Dickison, Gary H.; Lau, Anthony G. (2020)
      NASA has a long-term goal to go to Mars. The long duration spaceflight has many risks to astronaut health, including the risk of bone loss due to the absence of gravity and exposure to space radiation. There have been ...

    • Effects of galactic cosmic radiation on material properties of bone 

      Meyers, Michelle; Okulicz, Calvin J.; Thomas, Patricia; Davis, Catherine M.; Lau, Anthony G. (2021)
      One of the many missions of NASA is to develop a safer agent of space travel for astronauts. According to NASA, the average astronaut will be exposed to anywhere between 50 and 2,000 mGy of effective radiation. In a more ...

    • The Effects of Head Only Radiation on the Hardness of Bone 

      Lau, Anthony G.; Dickinson, Gary H.; Thomas, Patricia; Davis, Catherine M. (2019)
      NASA has a long term goal to go to Mars. The long duration spaceflight has many risks to astronaut health, including the risk of bone loss due to the absence of gravity and exposure to space radiation. There have been ...

    • Effects of Helium-4 Radiation on Bone Mechanics 

      Lau, Anthony G.; Connell, Rosalie; Dickinson, Gary H.; Davis, Catherine M. (2019)
      In the 50 years since NASA s first moon landing, space exploration has become more prevalent as the necessity for extraterrestrial resources has increased on Earth. Outside of Earth s magnetic field, there is a lack of ...

    • Finite element analysis of femoral neck strength losses due to space irradiation 

      Johnson, Dale R.; Lawrence, Summer E.; Livingston, Eric W.; Heinz, Robert D.; Davis, Catherine M.; Lau, Anthony G. (2017)
      Spaceflight leaves astronauts at risk for negative consequences to bone health. Sending a manned mission to Mars is a long term goal of the National Aeronautics and Space Administration (NASA). Because this trip will take ...

    • Long-Time Elastic Modulus of Rat Femurs Exposed to Radiation Using Microindentation 

      Lau, Anthony G.; Okulicz, Calvin J.; Dickinson, Gary H.; Davis, Catherine M. (2019)
      NASA has trips to both the Moon and Mars on their itinerary for the near future. Health and safety of the astronauts is of the upmost importance for the missions. Bone loss, or osteoporosis, is a known risk of space travel ...

    • Modeling space radiation induced bone loss in rat femurs through finite element analysis 

      Borg, Alex; Johnson, Dale; Lawrence, Summer; Livingston, Eric W.; Heinz, Robert D.; Davis, Catherine M.; Lau, Anthony G. (2016)
      Spaceflight leaves astronauts at risk for negative consequences to bone health. A long term mission of NASA has been to send a manned mission to mars. Taking over a month for astronauts to reach Mars, long term effects ...
