FORESAIL-1立方体卫星飞行任务，测量辐射带损失并演示离轨
FORESAIL-1 cubesat mission to measure radiation belt losses and demonstrate de-orbiting
摘要：
今天，近地空间正面临着一个范式的变化，因为新的航天器的数量实际上是飞涨。越来越多的小型卫星威胁着空间的可持续利用，因为如果不清除，空间碎片最终将使某些关键轨道无法使用。影响小型航天器健康并导致碎片的一个核心因素是辐射环境，由于对近地辐射环境本身及其受太阳风和外磁层驱动的可变性了解不全面，辐射环境是不可预测的。本文介绍了具有两个科学目标和一个技术目标的FORESAIL-1纳米卫星任务。第一个科学目标是测量高能粒子损失到大气中的能量和通量，在广泛的磁局部时间范围内具有代表性的能量和俯仰角分辨率。为了铺平道路，新的模型原位数据比较，我们还显示了沉淀电子通量与新的全球混合-弗拉索夫模拟Vrasiator获得的初步结果。FORESAIL-1飞行任务的第二个科学目标是测量源于太阳的高能中性原子。太阳ENA通量有可能对太阳爆发能量预算估计的知识做出重要贡献。技术目标是演示卫星离轨技术，并首次利用无推进剂超小型卫星进行轨道机动。FORESAIL-1将展示纳米卫星作出重要科学贡献的潜力，并通过使用具有成本效益的离轨技术促进空间的可持续利用。
英文摘要：
Today, the near-Earth space is facing a paradigm change as the number of new spacecraft is literally sky-rocketing. Increasing numbers of small satellites threaten the sustainable use of space, as without removal, space debris will eventually make certain critical orbits unusable. A central factor affecting small spacecraft health and leading to debris is the radiation environment, which is unpredictable due to an incomplete understanding of the near-Earth radiation environment itself and its variability driven by the solar wind and outer magnetosphere. This paper presents the FORESAIL-1 nanosatellite mission, having two scientific and one technological objectives. The first scientific objective is to measure the energy and flux of energetic particle loss to the atmosphere with a representative energy and pitch angle resolution over a wide range of magnetic local times. To pave the way to novel model - in situ data comparisons, we also show preliminary results on precipitating electron fluxes obtained with the new global hybrid-Vlasov simulation Vlasiator. The second scientific objective of the FORESAIL-1 mission is to measure energetic neutral atoms (ENAs) of solar origin. The solar ENA flux has the potential to contribute importantly to the knowledge of solar eruption energy budget estimations. The technological objective is to demonstrate a satellite de-orbiting technology, and for the first time, make an orbit manoeuvre with a propellantless nanosatellite. FORESAIL-1 will demonstrate the potential for nanosatellites to make important scientific contributions as well as promote the sustainable utilisation of space by using a cost-efficient de-orbiting technology.
