Summary
The satellite named STARLINK-2638 (OBJECT_ID: 2021-040BB) is a Starlink communication satellite manufactured by SPXS and owned by the same entity. It was launched on May 9, 2021, from Launch Pad LC40 at AFETR using a Falcon 9 launch vehicle. The satellite has dimensions of 0.2 meters in length, 2.8 meters in diameter, and spans 9 meters. Its dry mass is 248 kilograms, and it weighed 260 kilograms at launch. It features a Ku/Ka-band payload along with optical inter-satellite links on some prototypes. The satellite is equipped with krypton ion thrusters for propulsion and uses solar arrays and batteries for power supply. Its shape is described as "Box + pan."

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.
