With the advent of the Heliophysics/Geospace System Observatory (H/GSO), a complement of multi-spacecraft missions and ground-based observatories to study the space environment, data retrieval, analysis, and visualization of space physics data can be daunting. The Space Physics Environment Data Analysis System (SPEDAS), a grass-roots software development platform (www.spedas.org), is now officially supported by NASA Heliophysics as part of its data environment infrastructure. It serves more than a dozen space missions and ground observatories and can integrate the full complement of past and upcoming space physics missions with minimal resources, following clear, simple, and well-proven guidelines. Free, modular and configurable to the needs of individual missions, it works in both command-line (ideal for experienced users) and Graphical User Interface (GUI) mode (reducing the learning curve for first-time users). Both options have “crib-sheets,” user-command sequences in ASCII format that can facilitate record-and-repeat actions, especially for complex operations and plotting. Crib-sheets enhance scientific interactions, as users can move rapidly and accurately from exchanges of technical information on data processing to efficient discussions regarding data interpretation and science. SPEDAS can readily query and ingest all International Solar Terrestrial Physics (ISTP)-compatible products from the Space Physics Data Facility (SPDF), enabling access to a vast collection of historic and current mission data. The planned incorporation of Heliophysics Application Programmer’s Interface (HAPI) standards will facilitate data ingestion from distributed datasets that adhere to these standards. Although SPEDAS is currently Interactive Data Language (IDL)-based (and interfaces to Java-based tools such as Autoplot), efforts are under-way to expand it further to work with python (first as an interface tool and potentially even receiving an under-the-hood replacement). We review the SPEDAS development history, goals, and current implementation. We explain its “modes of use” with examples geared for users and outline its technical implementation and requirements with software developers in mind. We also describe SPEDAS personnel and software management, interfaces with other organizations, resources and support structure available to the community, and future development plans.

空间物理环境数据分析系统（SPEDAS）

随着太阳物理/地球空间系统观测站 (H/GSO) 的出现，用于研究空间环境、数据检索、分析和空间物理数据可视化的多航天器任务和地面观测站的补充可能令人望而生畏。空间物理环境数据分析系统（SPEDAS）是一个基层软件开发平台（www.spedas.org），现已得到NASA太阳物理学局的正式支持，作为其数据环境基础设施的一部分。它为十多个太空任务和地面观测站提供服务，并且可以遵循清晰、简单和经过充分验证的指导方针，用最少的资源整合过去和即将到来的空间物理任务的全部补充。它是免费的、模块化的，可根据各个任务的需要进行配置，可以在命令行（适合有经验的用户）和图形用户界面（GUI）模式（减少首次用户的学习曲线）下工作。这两个选项都有“crib-sheets”，即 ASCII 格式的用户命令序列，可以促进记录和重复操作，特别是对于复杂的操作和绘图。婴儿床增强了科学互动，因为用户可以快速准确地从数据处理的技术信息交换转向有关数据解释和科学的有效讨论。SPEDAS 可以轻松查询和摄取来自空间物理数据设施 (SPDF) 的所有国际日地物理 (ISTP) 兼容产品，从而能够访问大量历史和当前任务数据。计划纳入太阳物理学应用程序员接口 (HAPI) 标准将有助于从符合这些标准的分布式数据集中提取数据。尽管 SPEDAS 目前是基于交互式数据语言 (IDL) 的（以及与基于 Java 的工具（如 Autoplot）的接口），但正在努力进一步扩展它以与 python 一起使用（首先作为接口工具，甚至可能收到低于-引擎盖更换）。我们回顾 SPEDAS 的发展历史、目标和当前实施情况。我们通过面向用户的示例解释其“使用模式”，并概述其技术实现和要求，并考虑到软件开发人员。我们还描述了 SPEDAS 人员和软件管理、与其他组织的接口、社区可用的资源和支持结构以及未来的发展计划。
