Abstract

The results of a scientific and educational experiment on the SiriusSat-1 and SiriusSat-2 spacecraft carried out in Russia in the format Cubesat 1U+ are presented. The launch of two Sirius Sat-1,2 spacecraft was carried out on August 15, 2018 by astronauts from the ISS. The payload of the SiriusSat satellites is a detector based on several optically connected scintillators; it registers charged particles and \(\gamma\)-quanta in the energy release range of 0.3–3 MeV. The measurement mode provides both second-by-second monitoring and a detailed mode fixing the energy of each particle or quantum, as well as the corresponding time instant with a microsecond accuracy. Each satellite transmits \({\sim}100\) kB of scientific data daily, which are available on the space weather server of the Skobeltsyn Institute of Nuclear Physics, Moscow State University. During the flight, the variations in the precipitating and quasi-trapped electron fluxes of the outer Earth radiation belt and at the border of the South Atlantic Anomaly, and the dynamics of the particle fluxes and gamma rays depending on geomagnetic conditions have been studied. Additional possibilities are provided by the analysis of the passage of the areas of captured or precipitating particles by two closely flying satellites.

SiriusSat-1,2卫星的科学和教育性太空实验

摘要

介绍了在俄罗斯以Cubesat 1U +格式进行的SiriusSat-1和SiriusSat-2航天器的科学和教育实验的结果。国际空间站的宇航员于2018年8月15日发射了两架Sirius Sat-1,2航天器。SiriusSat卫星的有效载荷是一个基于几个光学闪烁体的探测器。它记录了在0.3–3 MeV的能量释放范围内的带电粒子和\（\ gamma \）-量子。测量模式提供了每秒的监视和详细的模式，这些模式固定了每个粒子或量子的能量，以及具有微秒级精度的相应时刻。每颗卫星发送\（{\ sim} 100 \）每天kB的科学数据，这些数据可从莫斯科国立大学Skobeltsyn核物理研究所的太空天气服务器上获得。在飞行过程中，研究了地球外部辐射带和南大西洋异常边界的降水和准捕获电子通量的变化，以及取决于地磁条件的粒子通量和伽马射线的动力学。通过分析两个近距离飞行的卫星对捕获或沉淀的颗粒区域的通过提供了其他可能性。
