Expedition Sound 是欧洲空间局（European Space Agency, ESA）推出的一档播客系列，邀请您通过耳朵去探索宇宙（Universe）。在数据声化（将数据转化为声音）的引导下，主持人 Zsófi Szalavári 从我们的太阳出发，深入太空深处，揭示 ESA 科学任务的空间望远镜（space telescope）教会了我们哪些关于宇宙的知识。
Expedition Sound is a podcast series by the European Space Agency (ESA) in which you’re invited to explore the Universe through your ears. Guided by sonifications – the translation of data into sound – host Zsófi Szalavári travels from our Sun out into the depths of space to uncover what the space telescopes of ESA’s science missions teach us about the Universe.
每一集都会在旅途中的不同目的地停留，Zsófi 将与 ESA 的科学家、天文学家（astronomer）和声化专家汇合，了解隐藏在我们航天任务（space mission）传回的数据中的科学知识。
Each episode stops at a different destination along the way, where Zsófi is joined by ESA scientists, astronomers and sonification experts, to learn about the science that is hidden in the data that our space missions send back to us.
该播客的核心理念是声音能让天文学（astronomy）变得更加平易近人。因此，除了科学内容外，您还可以听到视障天文学家的讲述，对他们而言，聆听为空间探测（space exploration）开启了一扇极具意义的大门。
At the heart of the podcast is the idea that sound can make astronomy more accessible. So, alongside the science, you can also hear from vision impaired astronomers, for whom listening opens an especially meaningful door into space exploration.
您可以在所有主流播客平台收听 Expedition Sound，包括 Apple Podcasts、Spotify、Podbean、Amazon Music 等。
You can listen to Expedition Sound on all major podcast platforms including Apple Podcasts, Spotify, Podbean, Amazon Music, and more.
第 1 集 – 我们的太阳、环日轨道器（Solar Orbiter）以及聆听太阳烟花
Episode 1 – Our Sun, Solar Orbiter, and listening to solar fireworks
在由 ESA 主导的 Solar Orbiter 任务数据所创建的声化引导下，我们探索了太阳的一些奥秘。我们与 ESA 项目科学家 Miho Janvier 探讨了 Solar Orbiter 如何研究这些奥秘，并听取了盲人天文学家兼科学传播者 Nic Bonne 关于声音如何让天文学变得更加无障碍的见解。
Guided by a sonification created with data from the ESA-led Solar Orbiter mission, we explore some of the mysteries of our Sun. We talk to ESA project scientist Miho Janvier about how Solar Orbiter is studying these mysteries and hear from blind astronomer and science communicator Nic Bonne how sound can make astronomy more accessible.

第 2 集 – 太阳系（solar system）、贝比科隆博水星探测计划（BepiColombo）以及飞向水星（Mercury）
Episode 2 – The Solar System, BepiColombo, and flying towards Mercury
通过对 ESA/日本航天局（JAXA）BepiColombo 数据进行声化处理，我们尽可能地模拟了乘坐航天器旅行的体验，感受飞向行星（planet）水星会是怎样的情景。我们与 ESA 项目科学家 Geraint Jones 讨论了 BepiColombo 将揭示关于这颗小型岩质行星（rocky planet）的奥秘，并从视障学生 Ben Ruggles 那里了解到他如何在朴茨茅斯大学通过声音进行科学研究。
Through a sonification of ESA/JAXA BepiColombo data, we get as close as possible to travelling aboard a spacecraft, experiencing what it would be like to fly towards planet Mercury. With ESA Project Scientist Geraint Jones, we talk about the mysteries that BepiColombo will reveal about this small rocky planet, and from vision impaired student Ben Ruggles we learn how he is doing science through sound at the University of Portsmouth.
第 3 集 – 我们的银河系（Milky Way galaxy）、盖亚（Gaia）、Plato 以及聆听恒星（star）的震动
Episode 3 – Our Milky Way galaxy, Gaia, Plato, and hearing stars wobble
我们深入银河系，通过对 ESA Gaia 任务观测到的星震进行声化处理，聆听恒星的心跳。我们与博士生 Sarah Kane 探讨了利用 Gaia 数据研究恒星演化（stellar evolution）的过程，并讨论了她作为一名视障研究人员的经历。Plato 项目的 ESA 项目科学家 Maximilian Günther 带我们超越太阳系，探索系外行星（exoplanet）的迷人世界。
We journey into the depths of our Milky Way galaxy and listen to the heartbeats of stars, through a sonification of starquakes observed by ESA's Gaia mission. We talk to PhD student Sarah Kane about using Gaia data to study stellar evolution and discuss her experiences as a visually impaired researcher. ESA Project Scientist for Plato, Maximilian Günther, takes us beyond our Solar System to explore the fascinating worlds of exoplanets.
第 4 集 – 太空深处、Euclid、空间激光干涉仪（LISA）以及引力的神秘效应
Episode 4 – The depths of space, Euclid, LISA, and the mysterious effects of gravity
通过受 ESA Euclid 任务对爱因斯坦环（Einstein ring）观测启发的声化处理，我们冒险进入太空深处，探索引力的一些神秘效应。我们听取了 Euclid 项目科学家 Valeria Pettorino 关于引力透镜效应（gravitational lensing）、爱因斯坦环和宇宙大尺度结构的介绍，并与 ESA 研究员 Lorenzo Speri 交流了声音如何帮助我们理解引力波（gravitational wave）以及 LISA 任务的未来发现。
Through a sonification inspired by observations of Einstein rings by ESA's Euclid mission, we venture into the depths of space to explore some of the mysterious effects of gravity. We hear from Euclid Project Scientist Valeria Pettorino about gravitational lensing, Einstein rings and the large-scale structure of the Universe, and chat with ESA Research Fellow Lorenzo Speri about how sound can help us understand gravitational waves and the future discoveries of ESA's LISA mission.
