Multiphysics Simulation of the NASA SIRIUS-CAL Fuel Experiment in the Transient Test Reactor Using Griffin

Tian Jing et al.

Summary: NASA is restarting efforts to develop nuclear thermal propulsion for interplanetary missions, focusing on advanced materials and fabrication methods. Simulation results of SIRIUS-CAL calibration experiment in TREAT showed successful matching of reactor power transient, but further reduction of uncertainty range is necessary.

Radiation Risks in a Mission to Mars for a Solar Particle Event Similar to the AD 993/4 Event

Fahad A. Zaman et al.

Summary: Evidence suggests a large solar particle event occurred in AD 993/4, with potential radiation risk to crew members on a mission to Mars estimated. Results indicate that while such an event may have severe consequences for astronauts in transit to Mars, the atmosphere of Mars provides some protection against it on the surface. Additional shielding may be required for certain scenarios.
