Abstract

Abstract. The North American Aerospace Defense Command (NORAD) tracking of the SpaceX Starlink satellite launch on 2022 February 3 is reviewed. Of the 49 Starlink satellites released into orbit, 38 were eventually lost. Thirty-two of the satellites were never tracked by NORAD. Two different physical mechanisms have been proposed published in Space Weather and one in arXiv to explain the satellite losses. It is argued that none of these three papers can explain the immediate loss of 32 of the 49 satellites. We suggest NORAD satellite tracking information for scientists to further investigate possible loss mechanisms.

北美防空司令部对 2022 年 2 月 Starlink 卫星的跟踪以及 32 颗卫星的立即损失

摘要回顾了北美航空航天防御司令部（NORAD）对 2022 年 2 月 3 日 SpaceX Starlink 卫星发射的跟踪情况。在释放进入轨道的 49 颗 Starlink 卫星中，有 38 颗最终丢失。其中 32 颗卫星从未被北美防空司令部跟踪。有人提出了两种不同的物理机制来解释卫星丢失的原因，一种发表在《空间天气》上，另一种发表在 arXiv 上。我们认为，这三篇论文都无法解释 49 颗卫星中 32 颗卫星立即丢失的原因。我们建议为科学家提供北美防空司令部的卫星跟踪信息，以进一步研究可能的损失机制。

期刊介绍： Nonlinear Processes in Geophysics (NPG) is an international, inter-/trans-disciplinary, non-profit journal devoted to breaking the deadlocks often faced by standard approaches in Earth and space sciences. It therefore solicits disruptive and innovative concepts and methodologies, as well as original applications of these to address the ubiquitous complexity in geoscience systems, and in interacting social and biological systems. Such systems are nonlinear, with responses strongly non-proportional to perturbations, and show an associated extreme variability across scales.
