最近，美国向外界发布了一项引人注目的举措——将其星链卫星大部队的轨道高度降至480公里，声称此举是出于环保考虑， 以加快报废卫星自然燃烧、减少太空垃圾。但这些理由看似正义，背后却隐藏着更为复杂的国际力量博弈。尤其是在中国空间 站的上空，频繁出现的危险接近事件，再一次将我们对美国太空计划的关注推向了高潮。 SpaceX创始人马斯克的星链计划，如今已经成为全球低轨道太空的一颗"明珠"。最初设计的1.2万颗卫星，后来把上限提升到 4.2万颗，使得星链在低轨道形成了一个庞大的网络，几乎覆盖了大部分地球表面。如今，在轨的星链卫星数量已经突破1万 颗，约占全球活跃航天器总数的六成，极大地提高了太空的拥挤度。 2021年，中国空间站先后遭遇两次来自星链卫星的"恶意靠近"，一种不可控的紧张气氛在宇宙中蔓延。这些情况让人不得不警 惕：如果未来发生碰撞，后果不堪设想。已经有卫星因为未能及时避让而解体，产生数以百计的太空碎片，对其他航天器形成 直接威胁。因此，可以说，美国的降轨决定并非简单的环保行动，而是深层次的战略布局。 星链的快速部署不仅关乎商业利益，更意味着其军事力正在被不断放大。随着乌克兰战争深入，其中的众多例子表明，星链 ...

根据SpaceX的规划，如果"星链"卫星发生故障或退役，将受运行轨道上的稀薄空气阻力影响而逐步降低 高度，最终在几个月内重返大气层并燃烧殆尽。然而随着太阳活动从当前的活跃高峰期转向活动水平很 低的极小期（2030年左右），近地轨道空气阻力减小，这也意味着"星链"卫星重返大气层的时间延长。 尼科尔斯称，受极小期影响，卫星从550公里的轨道高度返回大气层可能需要超过4年的时间。而若选择 更低轨道，该过程仅需几个月。 尼科尔斯还表示，"这些措施将进一步提高星座的安全性，尤其是在应对难以控制的风险方面，例如其 他卫星运营商的无协调机动和发射。"美国"商业内幕"网站注意到，去年12月，SpaceX表示，一颗"星 链"卫星与9颗中国卫星擦肩而过，险些相撞。该公司还报告称，去年年底另一颗"星链"卫星也疑似发生 爆炸，并在轨释放出少量"可追踪的低相对速度物体"。香港《南华早报》1月2日称，中方代表去年12月 在联合国安理会的一场会议上发言时表示，个别国家的商业卫星星座肆意扩张，缺乏有效监管，带来明 显的安全挑战。"以'星链'为例，其在轨卫星严重挤占频轨资源，增加航天器碰撞和产生空间碎片的风 险。" 根据欧洲航天局的监测数据， ...

"星链"工程副总裁迈克尔·尼科尔斯（Michael Nicolls）当天在社交媒体X平台写道："'星链'正在对其卫 星星座进行重大重组，重点是提高太空安全。" 1月2日，香港《南华早报》报道称，SpaceX此举旨在将卫星重新部署到太空碎片和其他计划中的卫星 星座较少的轨道区域，从而降低发生碰撞风险，并使卫星能够更快地脱离轨道。与此同时，就在几天 前，中方代表在联合国安理会一场会议上发言时表示，个别国家的商业卫星星座肆意扩张，缺乏有效监 管，带来显著安全挑战，并点名称，"星链"卫星曾两次迫近中国空间站致紧急避碰。 去年12月，"星链"一颗卫星因故障在太空产生碎片，曾引发广泛关注。路透社去年12月19日报道， SpaceX当天"罕见披露"，其旗下"星链"的一颗在轨卫星12月17日突发故障，在约418公里高度与地面失 去通信联系，并宣称产生了"少量"太空碎片。 【文/观察者网 熊超然】当地时间1月1日，美国太空探索技术公司（SpaceX）宣布将在2026年对其"星 链"（Starlink）互联网卫星星座进行重组，降低4400多颗卫星的轨道高度。 "'星链'卫星具有极高的可靠性，在超过9000颗在轨运行卫星中，仅有两 ...

Core Viewpoint - SpaceX's Starlink program has raised concerns regarding satellite collision risks, particularly following a recent incident where a Chinese satellite came within 200 meters of a Starlink satellite, leading to a dispute between SpaceX and China Aerospace Corporation over collision avoidance protocols [1][4]. Group 1: Incident Details - Michael Nichols, Vice President of SpaceX's Starlink program, reported a close approach incident involving a Chinese satellite and a Starlink satellite, which occurred without prior coordination [1]. - China Aerospace Corporation responded, asserting that all their launch missions utilize ground-based space awareness systems to select launch windows and avoid collisions with known satellites or debris, emphasizing this as a mandatory procedure [1][4]. Group 2: Starlink Operations and Challenges - Starlink has faced multiple collision threats, including two incidents in 2021 where Starlink satellites came close to the Chinese space station, prompting emergency collision avoidance maneuvers [4]. - As of February 2025, Starlink has over 6,750 satellites in orbit, with plans to expand to a constellation of 12,000 and eventually 42,000 satellites [4]. Group 3: Maneuvering and Collision Avoidance - From December 2024 to May 2025, Starlink satellites executed over 140,000 maneuvers to avoid collisions, which is 2.8 times more than the previous six months, complicating collision predictions for other organizations [5]. - Starlink satellites are designed to frequently adjust their orbits using electric propulsion systems, which is necessary due to their lightweight design and large solar panel area, making them susceptible to atmospheric drag [5]. Group 4: Coordination and Communication - Experts emphasize the need for responsible spacefaring nations to notify relevant parties when satellites change orbits to prevent collisions, particularly among operational satellites [6]. - Nichols highlighted that the lack of coordination among satellite operators poses significant risks, advocating for the sharing of satellite ephemeris data to enhance safety in space operations [7].
