摘要：

目前的撒萨观测站飞行任务延续了一个悠久而光明的传统，将基础物理学和行星科学界结合在一个单一的飞行任务中，在这两个领域都有雄心勃勃的目标。OSS是一项M级任务，在旅行者2号航天器飞越海王星系统近半个世纪后探索海王星系统。旅行者2号有几个发现，包括大黑斑（现已消失）和海卫一间歇泉。旅行者2号揭示了海王星大气层的动力学，并发现了海王星上方的四个环和环弧的证据。得益于一个大大改进的仪器，它将导致在太阳系最远的行星的研究一个惊人的进步。此外，撒萨观测站将提供一个独特的机会，在海王星系通过之后，对选定的柯伊伯带天体进行访问。它将巩固海卫一起源于海王星捕获的KBO的假设，并提高我们对太阳系形成的认识。探测器将搭载仪器，以便在巡航期间精确跟踪探测器。它允许执行最好的控制实验测试，在深空，广义相对论，基于太阳系形成的所有模型。开放源码软件是作为欧空局和美国航天局之间的一项国际合作提出的，使欧空局有能力向太阳系最远的行星和柯伊伯带天体发射M级飞行任务。拟议的飞行任务概况将允许发射一个500公斤级的航天器。探测器的设计主要受深空重力试验的约束，以尽量减少加速度计测量的扰动。

英文摘要：

The present OSS mission continues a long and bright tradition by associating the communities of fundamental physics and planetary sciences in a single mission with ambitious goals in both domains. OSS is an M-class mission to explore the Neptune system almost half a century after flyby of the Voyager 2 spacecraft. Several discoveries were made by Voyager 2, including the Great Dark Spot (which has now disappeared) and Triton's geysers. Voyager 2 revealed the dynamics of Neptune's atmosphere and found four rings and evidence of ring arcs above Neptune. Benefiting from a greatly improved instrumentation, it will result in a striking advance in the study of the farthest planet of the Solar System. Furthermore, OSS will provide a unique opportunity to visit a selected Kuiper Belt object subsequent to the passage of the Neptunian system. It will consolidate the hypothesis of the origin of Triton as a KBO captured by Neptune, and improve our knowledge on the formation of the Solar system. The probe will embark instruments allowing precise tracking of the probe during cruise. It allows to perform the best controlled experiment for testing, in deep space, the General Relativity, on which is based all the models of Solar system formation. OSS is proposed as an international cooperation between ESA and NASA, giving the capability for ESA to launch an M-class mission towards the farthest planet of the Solar system, and to a Kuiper Belt object. The proposed mission profile would allow to deliver a 500 kg class spacecraft. The design of the probe is mainly constrained by the deep space gravity test in order to minimise the perturbation of the accelerometer measurement.
