Study on the Configuration of Deep Space Particles Sampling and Return Spacecraft

Deep space particles such as solar wind particles or space dust sampling and return mission is popular in space science and deep space exploration. The configuration of typical deep space particle sampling and return spacecraft including Stardust and Genesis,and their characteristics are described and analyzed. Based the configuration of the circumlunar return and reentry spacecraft,a reasonable configuration of the deep space particles sampling and return spaceship was proposed. The spacecraft is made up of a noumenon frame and a return capsule generally. The noumenon frame's configuration should fit the return capsule and other instruments,while the return capsule's configuration should fit collecting sample and the pneumatic shape. The configuration adopts the inflatable sampler for particle collection,with small volume,light weight,high folding efficiency,reliable expansion and simple implementation;the spacecraft adopts the repeatable folding solar wing,meeting the needs of collecting different types of deep space particles.
