Do you still remember the satellite of the Deep Space Climate Observatory that has been hidden by NASA for nearly 20 years? After being sent to the Lagrange L1 point by the Falcon rocket in 2015, it has been running stably for more than four years. But just a week ago, the satellite, which was designed for five years, suddenly lost contact with the ground. It was alleged that the satellite was forced to go offline due to problems with the positioning system.

According to a spokesman for the US Department of Atmospheric and Marine Environment (NOAA), before the Deep Space Climate Observatory (DSCOVR) lost contact on June 27, the engineers discovered that the satellite platform had encountered a fault in the positioning system, so the satellite was allowed to enter. "Safe Mode". Although the staff subsequently diagnosed the satellite and attempted to fix the problem, the satellite in safe mode was unable to respond to any data, causing the satellite, which was at Lagrange L1 and 1.5 million kilometers from the Earth, to strike.

The Deep Space Climate Observatory was proposed in the late 1990s by the Clinton Administration. The satellite has two main purposes. One is to observe the solar wind, and to predict the solar spurt and solar storm on the earth 60 minutes ahead of the earth. The camera performs deep space imaging of the Earth to monitor the Earth's ozone layer, clouds, vegetation and land. However, after the satellite was manufactured in the late 1990s, it was completely sealed in NASA's Maryland week warehouse for eight years in the Bush era. Until the Obama administration pulled it out and re-launched in 2015, it was mainly used by NOAA.

xx虽然当时卫星设计的寿命为5年,但考虑到它在发射前已经存放在NASA仓库中15年,它将严重损失其正常生活。在深空气候观测站停止响应之前,它已进入轨道4年零4个月,并且接近设计寿命限制。现在又失去了联系。卫星可能很凶。

事实上,深空气候观测站的深空距离为150万公里。宇宙射线非常复杂,常常影响卫星系统信号。在过去的几年里,卫星一再停止并进入安全模式,但它们都迅速恢复。为了形成一个非常生动的比喻,这个深空气候观测台的错误就像我们的云服务器之一。系统崩溃后,我们按下重启按钮,但系统永远不会再次启动。我们只能面对客户。没有办法。

在深空气候观测站启动前进行测试

无论系统最终是否可以修复,我们对深空气候观测站的应用前景并不乐观。因为在2020年预算法案中,美国宇航局不再继续资助地球的地球观测部分,这意味着所有有限的170万美元预算将用于太阳风监测。无论卫星最终是否可以恢复,我相信几个月内就会有结果。如果定位系统无法恢复,卫星将逐渐偏离拉格朗日点,并在重力影响下成为太阳的人造小行星。
