These concentric, donut-shaped radiation belts are constantly changing \u0000due to a variety of physical processes caused by specific types of heliospheric \u0000structure. The radiation poses risks for astronauts and spacecraft systems. The \u0000understanding of these processes that operate across the universe can help with \u0000designs of future space missions as well as the understanding of the universe. \u0000The data gathered from the last three months of the Radiation Belt Storm Probes \u0000mission (RBSP mission) is examined for patterns and trends in the dynamics of \u0000the radiation belts and their relationships with solar activities. From the \u0000data, it is shown that the patterns of the high-energy particle dynamics in the \u0000belts follow the changes in solar activity. When the Sun’s magnetic field \u0000weakens, cosmic rays from deep space are able to carry an increased flux of \u0000energetic particles into the solar system. The outer belt exhibits a pattern of \u0000electron energization during cycles lasting an average of 27 days, \u0000corresponding to the time taken for one solar rotation. The sudden outward \u0000shift of the belts on July 19th, 2019 was most likely caused by the shutdown of \u0000one of the two Van Allen probes, as the relative position of the probe to the belts \u0000changed. Two solar wind streams that arrived from August 27th to the 28th \u0000caused the “dropout” event on August 28th, as the contact between the solar \u0000wind streams and magnetosphere pushed the magnetosphere’s boundary and enabled \u0000the particles outside the shifted boundary to escape into space. A positive \u0000polarity coronal hole high speed stream (CH HSS) contributed to the intense \u0000September electron re-energization process in the radiation belts starting on \u0000September 1st.","PeriodicalId":61930,"journal":{"name":"航空科学与技术(英文)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46115951","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The thermodynamic interpretation finds consistency with the model with a magneto-matter medium that is diamagnetic, in the context of ideal magnetohydrodynamics (MHD). It is further noticed that the CODET predicts a polytropic anomalous index for the electron gas of the Sun's corona. It is shown that this unusual characteristic is consistent with assuming that the low quiescent solar corona is a magneto-matter state which possesses an underlying structure that was earlier described to explain the 2-D adsorption process by a surface of a solid of molecules of a gas at a given temperature and pressure by Langmuir. In our case, it is assumed that we are in the presence of a 3-D similar coalescence process, i.e. a Langmuir amorphous lattice in thermodynamic equilibrium. In this way, constitutive properties of the medium magnetic permeability, the non-dispersive acoustic speed, the expected equilibration time for the 1.1 to 1.3$R_{odot}$, and energy density are determined quantitatively for most of the quiescent corona in a near solar minimum that extends for several months from 2008 to 2009.","PeriodicalId":61930,"journal":{"name":"航空科学与技术(英文)","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45502642","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the first stage of flight by using a carrier rocket, \u0000equipped with a chemical rocket engine, the astronauts are delivered on the \u0000international space station ISS. For flights from Earth orbit into Moon orbit, \u0000the design of a moonplane “MOND”, consisting of an interorbital module and a \u0000lunar module, has been developed. The interorbital module is an electric rocket, equipped with four \u0000superconductive magnetoplasma engine MARS.

The \u0000design of the lunar module with cabin astronauts, which is equipped with a chemical rocket engine for landing and take-off from \u0000the surface of the Moon, is developed. A method and a device for refuelling \u0000of the electrical rocket engines with nitrogen and for refuelling of the \u0000chemical rocket engines with oxygen and hydrogen, which are stored in cryogenic \u0000tanks of the moonplane in the liquid state is developed. \u0000The developed spacecraft is capable to regularly transport four \u0000astronauts off a moorage of ISS onto the surface of the Moon and back \u0000during 6 days.
