China has established a national industry alliance for very low Earth orbit (VLEO), signaling a strategic push to develop the commercial and military potential of altitudes below 300 kilometers. The alliance comes as multiple Chinese satellites have demonstrated sustained operations in this challenging regime, a region typically avoided due to higher atmospheric drag.
VLEO orbits, ranging from roughly 150 to 300 km, offer advantages for imaging and communications because of closer proximity to Earth, but require advanced propulsion systems to maintain altitude. Several Chinese startups developing electric and chemical thrusters have attracted investment, according to SpaceNews, as the alliance aims to coordinate technology development and regulatory frameworks.
The timeline for the alliance's formal launch was not specified in the report, but the initiative appears to align with China's broader space ambitions, including low-cost satellite constellations and responsive launch capabilities. Past Chinese missions have tested VLEO operations, but this marks the first coordinated national effort.
The move could accelerate competition with Western VLEO projects, such as those pursued by commercial firms in the United States and Europe. However, experts caution that sustained operations below 200 km remain technically demanding, and the economic viability of VLEO services is unproven outside niche applications.
