论文摘要

外部太阳能系统具有多种范围的对象,对我们太阳系的形成和演变,生命的出现和当前分布以及控制我们自己和超级球星系统的物理过程都有重要的线索。 这份白皮书总结了十月期的外行星分析小组(OPAG)的优先事项。考虑到要实现的科学,太阳系事件,技术准备和程序化因素的时机,我们的任务建议如下。 Opag强烈认可了Europa Clipper任务的完成和启动,并保持了选择时确定的科学能力,并在Jupiter进行了Juno扩展任务。在2023 - 2032年的十年中,Opag认可了两个指导任务的新起点:首先是通往海王星或天王星的任务,该任务是带有大气探针的Neptune或Aranus,其次是生命检测海洋世界任务,以及用于生命检测的其他技术发展。海王星任务是首选的,因为尽管海王星和天王星系统提供了同样令人信服的机会,但特里顿还是海洋世界的优先级目标,而不是Uranian卫星。海王星或天王星的任务应首先飞行,因为延迟威胁着关键的科学目标,并且需要进一步的技术发展才能实现生命检测任务。 除任务外,我们强调了保持健康的研究和分析(R&A)计划以及基于地球的观察计划的必要性。 Opag的前两个技术优先事项是快速开发前往海王星或天王星任务的下一代放射性同位素电源,以及开发关键的生命检测技术以支持海洋世界任务。最后,培养一个跨学科,多样,公平,包容和可访问的社区对俄罗斯社区至关重要。

The outer solar system has a diverse range of objects, holding important clues about the formation and evolution of our solar system, the emergence and current distribution of life, and the physical processes controlling both our own and exoplanetary systems. This White Paper summarizes the Outer Planets Analysis Group's (OPAG's) priorities in the Decadal Survey. Taking into account the science to be achieved, the timing of solar system events, technological readiness, and programmatic factors, our mission recommendations are as follows. OPAG strongly endorses the completion and launch of the Europa Clipper mission, maintaining the science capabilities identified upon its selection, and a Juno extended mission at Jupiter. For the decade 2023-2032, OPAG endorses a new start for two directed missions: first, a mission to Neptune or Uranus with atmospheric probe(s), and second, a life detection Ocean World mission, along with additional technological development for life detection. A Neptune mission is preferred because, while the Neptune and Uranus systems provide equally compelling opportunities, Triton is a higher priority ocean world target than the Uranian satellites. The mission to Neptune or Uranus should fly first because a delay threatens key science objectives, and additional technological development is required for a directed life detection mission. Along with missions, we emphasize the necessity of maintaining a healthy Research and Analysis (R&A) program as well as a robust Earth-based observing program. OPAG's top two technology priorities are rapid development of a next-generation radioisotope power source for a mission to Neptune or Uranus, and development of key life detection technologies in support of an Ocean World mission. Finally, fostering an interdisciplinary, diverse, equitable, inclusive, and accessible community is of top importance to the OPAG community.
