Micro-X探空火箭将于2011年1月18日发射，首次使用过渡边缘传感器（TES）X射线微量热仪对天文目标进行观测。128像素TES阵列位于2.165 m焦距的圆锥成像镜的焦点处，具有0.2-3.0 keV的带通。TES阵列的光谱分辨率将在1 keV下为2至4 eV。我们的科学计划专注于扩展源的高光谱分辨率观测。对于超新星遗迹（SNRs），我们的科学目标是绘制喷出物的速度结构，并通过等离子体线诊断研究等离子体的元素丰度和热力学和电离状态。对于星系团，Micro‐X可以独特地研究湍流、速度和等离子体的温度相。对于我们的初始飞行，我们已经将目标从明亮的东方结改变为最近在船尾座A SNR中发现的喷出物区域。2012年中期第二次飞行的目标是M8。
The Micro‐X sounding rocket payload will be launched on January 18, 2011 to make the first observation of an astronomical target with Transition‐Edge Sensor (TES) X‐ray microcalorimeters. The 128 pixel TES array lies at the focus of a 2.165 m focal length conical imaging mirror with a 0.2–3.0 keV bandpass. The spectral resolution of the TES array will be between 2 and 4 eV at 1 keV. Our scientific program is focused on high‐spectral resolution observations of extended sources. For supernova remnants (SNRs) our scientific objectives are to map the velocity structure of the ejecta, and study both elemental abundances and the thermodynamic and ionization state of the plasma through plasma line diagnostics. For clusters of galaxies, Micro‐X can uniquely study turbulence, velocities, and the temperature phases of the plasma.For our initial flight, we have changed our target from the bright eastern knot to a recently discovered ejecta region in the Puppis A SNR. The target of the second flight in mid‐2012 is M8...
