This article describes Daphne, a virtual assistant for designing Earth observation distributed spacecraft missions. It is, to the best of our knowledge, the first virtual assistant for such application. The article provides a thorough description of Daphne, including its question answering system and the main features we have implemented to help system engineers design distributed spacecraft missions. In addition, the article describes a study performed at NASA's Jet Propulsion Laboratory (JPL) to assess the usefulness of Daphne in this use case. The study was conducted with N = 9 subjects from JPL, who were asked to work on a mission design task with two versions of Daphne, one that was fully featured implementing the cognitive assistance functions, and one that only had the features one would find in a traditional design space exploration tool. After the task, they filled out a standard user experience survey, completed a test to assess how much they learned about the task, and were asked a number of questions in a semi-structured exit interview. Results of the study suggest that Daphne can help improve performance during system design tasks compared to traditional tools, while keeping the system usable. However, the study also raises some concerns with respect to a potential reduction in human learning due to the use of the cognitive assistant. The article ends with a list of suggestions for future development of virtual assistants for space mission design.

Daphne:设计地球观测分布式航天器任务的虚拟助手

本文介绍了设计地球观测分布式航天器任务的虚拟助手 Daphne。据我们所知,它是此类应用程序的第一个虚拟助手。本文对达芙妮进行了全面的描述,包括其问答系统以及我们为帮助系统工程师设计分布式航天器任务而实施的主要功能。此外,本文还介绍了在 NASA 喷气推进实验室 (JPL) 进行的一项研究,以评估达芙妮在此用例中的有用性。该研究由来自喷气推进实验室的 N = 9 名受试者进行,他们被要求使用两种版本的达芙妮来完成一项任务设计任务,一种是完全实现认知辅助功能的版本,并且只有在传统设计空间探索工具中才能找到的功能。任务完成后,他们填写了标准的用户体验调查,完成了一项测试以评估他们对任务的了解程度,并在半结构化的离职面谈中被问到了一些问题。研究结果表明,与传统工具相比,Daphne 可以帮助提高系统设计任务期间的性能,同时保持系统的可用性。然而,该研究也引起了一些担忧,即由于使用认知助手可能会减少人类学习。文章最后列出了对未来发展太空任务设计虚拟助手的建议。并在半结构化的离职面谈中被问到了许多问题。研究结果表明,与传统工具相比,Daphne 可以帮助提高系统设计任务期间的性能,同时保持系统的可用性。然而,该研究也引起了一些担忧,即由于使用认知助手可能会减少人类学习。文章最后列出了未来发展太空任务设计虚拟助手的建议。并在半结构化的离职面谈中被问到了许多问题。研究结果表明,与传统工具相比,Daphne 可以帮助提高系统设计任务期间的性能,同时保持系统的可用性。然而,该研究也引起了一些担忧,即由于使用认知助手可能会减少人类学习。文章最后列出了对未来发展太空任务设计虚拟助手的建议。该研究还提出了一些担忧,即由于使用认知助手可能会减少人类学习。文章最后列出了对未来发展太空任务设计虚拟助手的建议。该研究还提出了一些担忧,即由于使用认知助手可能会减少人类学习。文章最后列出了对未来发展太空任务设计虚拟助手的建议。
