For many decades, we have sent cameras to other worlds, but have never successfully listened to one. Since the 1990s, Leighton argued the usefulness of obtaining acoustic data from extraplanetary environment to which we could send probes, such as the moon Europa's oceans and the atmospheres of Mars, Venus, Titan and Jupiter. This dream was realised when, in 2021, the Perseverance rover landed on Mars. Its microphone has recorded aerodynamic signals (e.g. the wind noise of a passing dust devil), dust impacts (when said dust devil passed right over Perseverance) and acoustic signals (the rotor blade tones of the accompanying helicopter drone, Ingenuity from up to 100 m distant; and the shock waves from rocks up to 20 m distant that are impacted by Perseverance's laser).Leighton and Joseph were invited in February 2023 to the International Space Science Institute to view the Perseverance data. Such was the value of their insights, they are already the only UK co-authors on the paper (published today1) from the Perseverance team showing the value of microphone signals for science to investigate properties of the Martian atmosphere that are currently a mystery, such as the turbulence and temperature profile near the ground). This PhD project will analyse the microphone data that is still coming from Perseverance, recommend missions for Perseverance to take new data, and conduct on-Earth experiments to design the microphone array for the next Mars rover mission, and for future missions (a microphone has now been allocated to Titan's future Dragonfly helicopter).

几十年来，我们向其他世界发送了摄像机，但从未成功收听过。自20世纪90年代以来，雷顿一直在论证从行星外环境获取声学数据的有用性，我们可以向这些环境发射探测器，例如月球欧罗巴的海洋以及火星、金星、土卫六和木星的大气。这一梦想是在2021年，毅力漫游车登陆火星时实现的。它的麦克风记录了空气动力学信号(例如，经过的沙尘暴的风声)、沙尘撞击(沙尘暴正好经过毅力)和声音信号(伴随的直升机无人驾驶飞机的旋翼音调，从100米以外的独创性；以及来自20米远的岩石的冲击波，受到毅力的激光影响)。莱顿和约瑟夫于2023年2月被邀请到国际空间科学研究所查看毅力的数据。这就是他们洞察力的价值，他们已经是毅力团队论文(今天发表)中唯一的英国合著者，展示了麦克风信号对科学研究火星大气属性的价值，这些属性目前是一个谜，例如地面附近的湍流和温度分布。这个博士项目将分析仍然来自毅力的麦克风数据，建议毅力任务获取新的数据，并进行地面实验，为下一次火星漫游车任务和未来的任务设计麦克风阵列(现在已经为泰坦未来的蜻蜓直升机分配了一个麦克风)。
