href="data/attachment/portal/202001/16/153024ibqvbxz0fs45b66x.jpg" target="_blank"><img src="data/attachment/portal/202001/16/153024ibqvbxz0fs45b66x.jpg"></a></p></div><div><br></div><div> 昨天在夏威夷檀香山举行的美国天文学会（AAS）第235次会议上，举行了题为“卫星对天文学的挑战”的特别会议。该会议由国家科学基金会位于亚利桑那州图森的光学红外天文学研究实验室的康妮·沃克（ConnieWalker）主持，是由于与SpaceXStarlink巨型星座的建造有关的最新进展而引起的，但是会议的重点是讨论该卫星的前景。总的来说，正如其他几家公司计划建造自己的坚固卫星群一样。</div><div><br></div><div> Starlink是会议的焦点，这丝毫没有让人感到惊讶。现在，SpaceX已发射了三批小卫星，总数约为180个。每次发射都伴有灯光秀，其中可见到有序的Starlink卫星在夜空中滑行。这种类似火车的效果持续了一周或更长时间，直到卫星散布到更高的服务轨道，但即使到那时，它们仍然是肉眼可见的。也许并不奇怪，Starlink火车已经破坏了天文观测。</div><div><br></div><div> 这当然是一个问题，但另一个问题与预计在未来几年进入轨道的庞大卫星数量有关。SpaceX最终希望其Starlink星座由数万颗卫星组成，而其他公司（例如OneWeb，Telsat和Amazon）则希望构建自己的多卫星星座。私营部门将把太空中的物体数量增加一个数量级，而这种空前的实验（对后果没有任何明显的考虑）可能使天文观测破坏到令人震惊的程度。</div><div><br></div><div> 哈佛-史密森天体<a href="http://theory.oecr.com" target="_blank" class="relatedlink">物理</a>学中心的天文学家，卫星专家乔纳森·麦克道尔（JonathanMcDowell）参加了这次特别的AAS会议，并与他的同龄人进行了交谈。他还与SpaceX代表会面。</div><div><br></div><div> 麦克道尔在一封<a href="http://electronic.oecr.com" target="_blank" class="relatedlink">电子</a>邮件中告诉Gizmodo：“我确实相信SpaceX会为解决这个问题做出真诚的努力。”“我认为它们可以使卫星变得比肉眼所能看到的更暗，这对不给非天文学家造成破坏的夜空是微不足道的。”</div><div><br></div><div> 至于专业的天文学家，他担心一年中的某些时候，这些卫星将“至少构成一个大问题”，他说，他担心天文学家们甚至还没有想到这些问题。</div><div><br></div><div> SpaceNews报道，在昨天的会议上，SpaceX卫星政府事务副总裁PatriciaCooper说：“亮度和可见度的水平令我们感到惊讶。”</div><div><br></div><div> 库珀说，这种出乎意料的光度是由于卫星必须被放置在低轨道上以及它们的大型<a href="http://solar.oecr.com" target="_blank" class="relatedlink">太阳能</a>电池阵列最初被定向的方式的结果。一旦进入其预定的轨道（距离地球约550公里（342英里）），它们的亮度就会大大降低，但仍然可以从地面上看到它们。</div><div><br></div><div> SpaceX对此问题做出了回应。对于最近一次的部署-SpaceX成为世界上最大的商业卫星运营商-一颗Starlink卫星经过了特殊的深色涂层处理，旨在降低其反射率。我们要等到2月卫星投入使用后，这种解决方案是否能正常工作。</div><div><br></div><div> 此外，据《华盛顿邮报》报道，这家私人太空公司正在向天文学家提供每颗Starlink卫星的坐标，他们可以在计划观测时使用这些信息。</div><div><br></div><div> 库珀说：“我们还不知道这些缓解措施是否有用和有效。”“我们倾向于非常快速地工作。我们倾向于<a href="http://opticaltest.oecr.com" target="_blank" class="relatedlink">测试</a>，学习和迭代。”</div><div><br></div><div> 会议还讨论了总体上的巨型星座，讨论了这些卫星阵列如何影响科学观测，无论这些卫星是用于电信（如Starlink的情况），还是对地球表面的全面勘测（例如拟议的ICEYE星座），这将涉及配备合成孔径雷达（SAR）的卫星群。</div><div><br></div><div> 据英国广播公司报道，来自密歇根大学的天文学家帕特里克·塞策（PatrickSeitzer）在会上发表讲话，警告人们注意有害影响，例如图像上出现多条条纹，像鬼影一样的伪影，探测器被光饱和以及对电子设备的干扰。</div><div><br></div><div> 塞泽尔在英国广播公司（BBC）中说：“低地球轨道上的巨型星座即将到来，而且它们正在迅速发展。”“新的卫星比轨道上99％的物体亮，”他补充说，Starlink卫星的最初一批“仅仅是个开始”。</div><div><br></div><div> Seitzer建议SpaceX做到这一点，以使其Starlink卫星即使在其服务轨道上也无法肉眼看到，并且该公司致力于降低这些物体的亮度，以防止大型专业望远镜过饱和。。他说，令人不安的是，维拉·C·鲁宾天文台（以前称为大型天气观测望远镜）将受到巨型星座的严重影响，因为该天文台及其高敏感度的设备将每三天绘制一次整个天空。</div><div><br></div><div> 会议上提到的另一个问题是其中一些卫星，例如上述的ICEYE，可能会造成过度的无线电干扰。国家广播天文台（NRAO）的哈维·李斯特（HarveyLiszt）在会上对记者说，如果SAR指向直接回望它的射电望远镜，则SAR“将烧毁射电天文接收机，”BBC报道。</div><div><br></div><div> 希望这些讨论将进一步迫使私营部门在将其<a href="http://b.oecr.com/sell" target="_blank" class="relatedlink">产品</a>投入太空之前采取明智的做法。我们在游戏中这么晚才进行这些对话，实在令人失望。能够预测低地球轨道上成千上万甚至数十万颗卫星会影响我们对宇宙的看法，这并不完全是火箭科学。</div><div><br></div><div><br></div><div><section style="color: rgb(143, 143, 143);
