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 px $\times$  256 px @ 55 μm), 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$°$  $\times$  1.2$°$ and operates in the energy range of 3 – 60 keV. The second telescope was a one-dimensional LE with a focal length of 243 mm and a FOV of 2.7$°$  $\times$  8.0$°$ for the energy range 3 – 40 keV. The X-ray telescopes were supplemented by a camera in the visible spectrum with 1.280 px $\times$  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.

本文介绍了火箭实验（REX），该实验是美国宇航局采用水回收技术的探空火箭“黑布兰特” IX（Black Brant IX）进行的双有效载荷火箭运动的一部分。该任务是一次亚轨道探测火箭飞行，于2018年4月4日发射并恢复，目标是维拉超新星残余。REX的目的是对专为太空应用设计的机载设备的技术准备水平进行分类。这些设备是两台广角X射线望远镜，由龙虾（LE）光学器件和未冷却的Timepix检测器（256  px）组合而成 $\times$  256 像素@ 55μm  ）和其他传感器。第一台望远镜使用LE模块的二维组合，其焦距为1  m，视场（FOV）为1.0$°$  $\times$  1.2$°$并在3  –  60  keV的能量范围内运行。第二台望远镜是一维LE，焦距为243  mm，FOV为2.7$°$  $\times$  8.0$°$能量范围为3  –  40  keV。X射线望远镜还配有可见光谱为1.280  px的照相机 $\times$  1,024 像素分辨率，该分辨率用于获取观测到的源图像并验证火箭运载器的最终指向。其他设备还包括红外阵列传感器和惯性测量单元，已针对未来的小型卫星飞行进行了测试。数据处理程序和通信系统是使用机器人操作系统构建的，并且系统和电子设备都在飞行中进行了部署和操作。启动后成功恢复了硬件，并提​​取了数据。
