Approaches to Mass Reduction of Spacecraft System in Manned Exploration to Near Earth Asteroid
摘要
Abstract
To reduce the mass of spacecraft system in manned exploration to near earth asteroid (NEA),three technical approaches are proposed.They are sending a part of the propulsion module to the target asteroid in advance,applying the inflatable module and developing nuclear propulsion,respectively.One manned asteroid exploration spacecraft system as well as its mass calculation method proposed before are introduced.On the basis of them,the mass calculated of the spacecraft system in a manned exploration case to NEA are obtained with the use of the three approaches.Comparison among the three approaches on the mass reduction of the spacecraft system is made,and the characters of each approach based as well as difficulty in the application are discussed.It's shown that all of the approaches can effectively reduce the mass of the manned spacecraft system,which is conducive to enhancing the feasibility of the manned exploration mission to NEA.关键词
