论文摘要
本文介绍了火箭实验（REX），该实验是NASA发声的Rocket Black Brant IX借助水回收技术的双重有效载荷火箭运动的一部分。这项任务是轨道响起的火箭飞行，于2018年4月4日推出并恢复，并针对Vela Supernova Remnant。 Rex的目的是对设计用于空间应用的机载设备的技术准备水平进行分类。这些设备是两个宽场X射线望远镜，由龙虾眼（LE）光学元件和未冷却的时台检测器（256 x 256 px @ 55 um）和其他传感器组合。第一个望远镜使用二维LE模块的二维组合，焦距为1 m，视场（FOV）为1.0 x 1.2 ver，并在3-60 keV的能量范围内运行。第二个望远镜是一维LE，其焦距为250 mm，FOV为3-40 KEV的能量范围为2.7 x 8.0度。 X射线望远镜用1,280 x 1,024 PX分辨率在可见光谱中补充了摄像头，该分辨率用于获取观察到的源图像并验证火箭载体的结果指向。其他设备还包括针对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。数据处理程序和通信系统是使用机器人操作系统构建的，并且在飞行中部署并运行了系统和电子设备。发射后成功恢复了硬件并提取数据。
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.
