标题： REX: X-ray experiment on the Water Recovery Rocket

摘要： 本文介绍了火箭实验（REX），这是NASA探空火箭黑布兰特九号的双载荷火箭任务的一部分，采用了水回收技术。 这次任务是一次亚轨道探空火箭飞行，于2018年4月4日发射并回收，目标是维拉超新星遗迹。 REX的目的是对用于空间应用的机载设备的技术成熟度进行分类。 这些设备包括两个宽视场X射线望远镜，由龙虾眼（LE）光学元件与非冷却Timepix探测器（256 x 256 px @ 55 um）组合而成，以及额外的传感器。 第一台望远镜使用了LE模块的二维组合，焦距为1米，视场（FOV）为1.0 x 1.2度，在3 - 60 keV的能量范围内工作。 第二台望远镜是一种一维LE望远镜，焦距为250毫米，视场为2.7 x 8.0度，在3 - 40 keV的能量范围内工作。 X射线望远镜还配备了可见光谱的相机，分辨率为1,280 x 1,024像素，用于获取观测源的图像并验证火箭载体的指向。 其他设备还包括用于未来小型卫星任务测试的红外阵列传感器和惯性测量单元。 数据处理和通信系统是使用机器人操作系统构建的，系统和电子设备在飞行中部署并运行。 硬件在发射后成功回收，数据也被提取出来。 显示英文摘要

摘要： This paper presents Rocket Experiment (REX) that was part of a dual payload rocket campaign for NASA's sounding rocket Black Brant IX with water recovery technology. This mission was a suborbital sounding rocket flight that was launched and recovered on April 4, 2018 and targeted the Vela supernova remnant. The purpose of REX was to classify the Technology Readiness Level of onboard devices designed for space applications. The devices were two wide-field X-ray telescopes consisting of a combination of Lobster-Eye (LE) optics with an uncooled Timepix detector (256 x 256 px @ 55 um), and additional sensors. The first telescope uses a two-dimensional combination of LE modules with a focal length of 1 m and a Field of View (FOV) of 1.0 x 1.2 deg and operates in the energy range of 3 - 60 keV. The second telescope was a one-dimensional LE with a focal length of 250 mm and a FOV of 2.7 x 8.0 deg for the energy range 3 - 40 keV. The X-ray telescopes were supplemented by a camera in the visible spectrum with 1,280 x 1,024 px resolution, which was used to obtain images of the observed sources and to verify the resulting pointing of the rocket carrier. Other devices also include infrared array sensors and inertial measurement units tested for future small satellite missions. The data handler and communication system were built using the Robot Operating System, and both the system and the electronics were deployed and operated in flight. The hardware was successfully recovered after the launch and the data were extracted.
