在它能够实现这一宏伟目标之前需要确保所有的系统都正常。在周五的简报中，NASA宣布韦伯”即将完成使用近红外相机（NIRCam）仪器对准天文台主镜的第一阶段，这一过程长达数月之久”。 韦伯的主镜由18个镀金的六边形片段组成，需要一起工作，校准任务将确保NIRCam能够收集光线，然后让这些镜片中的每个镜片都能聚焦来自同一星源的星光，事实证明它成功了。 在美国宇航局发布的包含一些看上去就像是马赛克的图像中，该望远镜“睁眼”后看到的第一颗星出现了18次。它可能看起来有点乱，但这表明韦伯正在按照既定方式运行。这颗星看起来随机地散落在这些图像上，这是因为镜片还没有对准。在接下来的一个月左右，团队将逐步调整反射镜，直到18个图像聚焦成一个单一的恒星。 除了韦伯的第一颗星，NASA还分享了一张由NIRCam仪器内的特殊镜头拍摄的主镜自拍照，这对于团队而言精彩的奖励甜点，也是对一项没有专门配备自拍相机的任务的巧妙替代。 “向太空发射韦伯当然是一个令人兴奋的事件，但对于科学家和光学工程师来说，这无疑是一个巅峰时刻，当来自恒星的光线成功地通过系统下到探测器上时，”韦伯项目科学家Michael McElwain说。 对于地球上所有热爱天文学的人而言，这是韦伯在太空中早期的一个值得庆祝的时刻，但这只是一个较长过程的开始。韦伯的仪器仍在冷却，以保证进入它们的主要工作温度，镜片的调整也在持续进行着。 最好的消息是来自韦伯的信息：到目前为止，一切都很好。
