Abstract

The Sun is one of the most vital celestial bodies within solar system. Scientific researches from China on the Star Sun are impressively emerging in the recent decade.At present,China has put forward a mission similar to Parker Mission。 As one of the tasks supporting this mission, the space environments within a few solar radii have been simulated and assessed in this paper. It is necessary to make certain what severe situations the spacecrafts should be faced up to before the mission is granted. Simulations have shown the radiation level for the near Sun orbiters at altitude of several solar radii is much more severe than that for the near Earth orbiters at least by 1000 times. 20 millimeters of aluminum shielding might effectively reduce the radiation level of the spacecrafts.Hundreds of Krad (si) radiation will be accumulated in a five-year mission even though 20 millimeters of aluminum shielding is adopted to relieve the radiation effects.
