4,400 Starlink Satellites To Move To Lower Orbit

SpaceX的星链计划今年将把大约4400颗卫星转移到较低的地球轨道,以提高安全性并降低日益拥挤的空间环境中的风险。据星链工程副总裁迈克尔·尼科尔斯称,此举将降低碰撞概率,并能更快地使失效卫星脱轨。 这一决定部分受到太阳活动的影响,太阳活动会影响大气密度和卫星寿命。尽管星链目前运行着超过9000颗卫星,只有两颗目前失灵,但星链仍然优先考虑负责任的太空管理。 最近,该公司与卫星35956失去联系,预计在几周内重返大气层,不会对国际空间站构成威胁。星链的发展速度很快,已连接全球超过460万用户,甚至引起了美国空军的兴趣,希望将其整合到军事行动中。

SpaceX will move about 4,400 Starlink satellites to a lower orbit this year to better control risks and improve safety, the company announced Friday.

Michael Nicholls, vice president of Starlink engineering, posted the news on X, saying the adjustment would increase space safety in several ways.

Elon Musk’s Starlink system contributes more than 9,000 satellites to an increasingly crowded Earth orbit. Of those in the Starlink system, only two are not functioning, according to Nicholls.

Nicholls also noted that the atmospheric changes brought on by solar activity can affect satellite operations. An active sun causes a thicker atmosphere, which can bring spacecraft down faster.

Low solar activity, such as during the solar minimum after 2030, can have an opposite effect.

The number of debris objects and planned satellite constellations at the lower orbit—below 500 kilometers from Earth—is smaller, which reduces the likelihood of collision, Nicholls stated.

If a satellite does fail in orbit, Starlink wants to remove it as quickly as possible, improving the safety of the rest of the satellite constellation, Nicholls said.

Starlink also announced Thursday it had lost contact with one of its satellites and that it would work with NASA to monitor it.

“On December 17, Starlink experienced an anomaly on satellite 35956, resulting in loss of communications with the vehicle at 418 km,” Starlink posted on X.

The satellite was largely intact, tumbling, and is expected to reenter the Earth’s atmosphere within weeks. It poses no risk to the orbiting Space Station or its crew, the company stated.

“As the world’s largest satellite constellation operator, we are deeply committed to space safety. We take these events seriously,” the post said.

Starlink has seen explosive growth in the past five years, expanding into a global internet provider with millions of subscribers and challenging traditional satellite and terrestrial broadband internet providers.

The company connected more than 4.6 million users, according to its 2024 year-end report.

In five years, SpaceX has activated internet for more than 2.8 billion people around the world, including in some of the most remote parts of the planet, according to the report.

The U.S. Air Force is also conducting research to consider integrating Starlink into its Ghostrider gunships or heavy-lift cargo planes. Air Force Special Operations Command published a notice Tuesday requesting information on Starlink and its military version, Starshield.
