Summary
The satellite named STARLINK-2357 (OBJECT_ID: 2021-021AP) is a Starlink communication satellite owned by SPXS and was launched on March 14, 2021, from LC39A at AFETR using a Falcon 9 launch vehicle. It has dimensions of 0.2 meters in length, 2.8 meters in diameter, and spans 9 meters. The satellite's dry mass is 248 kilograms with a total launch mass of 260 kilograms. Equipped with Ku/Ka-band payload (all) and optical inter-satellite links (prototypes), it utilizes solar arrays and batteries for power and krypton ion thrusters as its motor system. Its shape is described as box + pan, and it operates in a communication mission role.
Starlink is a satellite constellation developed by SpaceX with the aim of providing global broadband internet coverage. Thousands of small satellites are deployed in low Earth orbit (LEO), enabling high-speed internet access even in remote areas. However, the rapid increase in satellites raises concerns about space debris and the potential for collisions, which can lead to further debris creation and endanger other spacecraft. Additionally, the sheer number of Starlink satellites can affect astronomical observations by increasing light pollution. Proper deorbiting plans and international coordination are essential to mitigate these challenges and ensure long-term sustainability in space.

China's Rocket Factory Finds a Second Gear
In 2024, China launched 68 orbital missions. In 2025, the number jumped to 97. In 2026, state media and Western analysts agree the target is 140 or more. Most of that growth is being driven by two state-backed mega-constellations, a half-dozen private launch companies hitting stride, and a deliberate national pivot toward commercial space. Beijing is no longer trying to catch SpaceX. It is trying to build an industrial base that outlasts one.
