The 2-unit CubeSat INSPIRE-2/AU03 was designed, built, tested, delivered, and accepted by the European Union’s QB50 project in less than 10 months and for less than US$120,000 in non-salary outlays including launch, despite being a first satellite. It carried 5 instruments (a multi-Needle Langmuir Probe, a diffraction-limited spectrograph, an advanced GPS receiver, and 2 radiation detectors) and the satellite hardware included both Commercial Off-The-Shelf (COTS) and Australian components. INSPIRE-2 was deployed into space from the International Space Station by Nanoracks on 26 May 2017 following an Atlas V launch. The satellite was brought online a month after launch as a result of a major campaign with the international radio amateur community. The uplink function of the Communications board was badly damaged in July 2017 in the first of that year’s two major, extended, space weather periods, plausibly due to radiation damage. While INSPIRE-2’s radio beacons were resurrected and continued for over a year the Communications board’s handshaking protocols meant that downlinking of data was not possible. INSPIRE-2 lived for over a year in space with mostly functioning systems. This paper summarises the major firsts and importance of INSPIRE-2 and its fellow Australian QB50 CubeSats UNSW-EC0 and SuSat (e.g., the first Australian CubeSats and the first Australian-built satellites in 16 years), as well as the science and technical goals, instruments, spacecraft systems, recovery, initial data, and evidence that the major space weather events of 12 July - 4 August 2017 significantly damaged INSPIRE-2 and caused an outage from 26 July to 5 September 2017. It also discusses the lessons learned and the reasons why CubeSats in constellations like QB50, whether international or Australian, provide excellent opportunities for scientific, technical, and commercial development, public outreach and engagement, and international engagement.

用于 QB50 项目的 INSPIRE-2 CubeSat

2 单元 CubeSat INSPIRE-2/AU03 在不到 10 个月的时间里设计、建造、测试、交付并被欧盟的 QB50 项目接受，并且包括发射在内的非工资支出不到 120,000 美元，尽管它是第一个卫星。它携带 5 个仪器（一个多针朗缪尔探测器、一个衍射极限光谱仪、一个先进的 GPS 接收器和 2 个辐射探测器），卫星硬件包括商用现货 (COTS) 和澳大利亚组件。INSPIRE-2 于 2017 年 5 月 26 日在 Atlas V 发射后由 Nanoracks 从国际空间站部署到太空。由于与国际无线电业余爱好者社区的一项重大活动，该卫星在发射一个月后上线。通信板的上行链路功能于 2017 年 7 月在该年两个主要、延长的空间天气期中的第一个严重损坏，可能是由于辐射损坏。虽然 INSPIRE-2 的无线电信标复活并持续了一年多，但通信委员会的握手协议意味着数据的下行链路是不可能的。INSPIRE-2 在太空中生活了一年多，大部分系统都在运行。本文总结了 INSPIRE-2 及其同行的澳大利亚 QB50 CubeSats UNSW-EC0 和 SuSat（例如，第一颗澳大利亚立方体卫星和 16 年来第一颗澳大利亚制造的卫星）的主要首创和重要性，以及科学和技术目标，仪器，航天器系统，恢复，初始数据，
