Stareye Constellation Begins Networking Trials as Space Debris Observation Moves Toward 'Watching Space from Space'

Highlights

• Ceres-2 Y3 launches four satellites in one mission
• Stareye satellite focuses on observing space debris
• Stareye constellation planned for 156 satellites, test-first

Four Satellites Reach Orbit as Ceres-2 Y3 Returns to Flight Successfully

At 7:37 a.m. Beijing time on Nov 7, the Ceres-2 Y3 carrier rocket lifted off from the Jiuquan Satellite Launch Center, successfully sending four satellites—the Guanlan test satellite, YunYao-1 28, the North University of China-1 satellite, and the Juntian-1 06A satellite—into their planned orbits. The flight test mission was a complete success. (Source: IT Home)

This was Ceres-2's first launch since its maiden flight failed nine and a half months ago. For a commercial rocket, a successful return to flight means the model has entered a continuous launch cadence that can be repeatedly verified, but a single success is not enough to show that reliability has stabilized. Launch frequency and fulfillment records going forward are the metrics to watch.

Stareye Satellite: Putting a Camera in Space to Observe Debris

Among the four satellites now in orbit, the Stareye space situational awareness satellite carries a special mission. Unlike conventional Earth observation satellites, it observes spacecraft operating in space, with a focus on space debris, providing space traffic management services for on-orbit spacecraft.

The satellite carries a camera for space and aerospace situational awareness and operates in a dawn-dusk orbit. The camera always observes along the direction of sunlight, capturing sunlight reflecting off space debris to record debris trajectories, then performing orbit determination, association, and cataloging of the debris—essentially building a database of all objects in space.

The reason for choosing a space-based approach lies in the limitations of ground-based observation: ground-based observation of space targets is constrained by geography and climate and has gaps in temporal and spatial coverage. Putting cameras in space enables "watching space from space." (Source: IT Home)

Debris Count and Constellation Plan

Data shows that low-orbit space debris in the 1 cm to 10 cm range has reached the million level. These "invisible threats" are among the biggest risks to spacecraft safety. More than 10,000 active satellites are now in near-Earth orbit worldwide, and the number of space objects continues to climb. (Source: IT Home)

The Stareye constellation is planned for 156 satellites in total, following a test-first, phased-construction approach: first, multiple test satellites such as Stareye-01 will assess in orbit the reliability of camera imaging, onboard computing power, intelligent algorithms, and the entire space-ground sensing system.

It is important to distinguish that this launch is an initial step in networking verification; the constellation has not yet entered large-scale deployment. Whether the 156-satellite plan can proceed on schedule depends on the in-orbit performance of the test satellites in imaging quality, onboard computing power, and cataloging accuracy—metrics for which no public results exist yet, making them nodes worth tracking going forward.

Points to Watch

Space debris monitoring has long relied on the ground-based radar and optical networks of a small number of institutions. Commercial companies entering this field are essentially seeking a position on the data-supply side of space traffic management. If Stareye can turn debris cataloging into a continuously updated database, its value will go beyond launch services to providing satellite operators with the basis for collision-avoidance decisions. The verification cycle for this path is measured in years; in the near term, the focus should be on the in-orbit assessment conclusions of the test satellites rather than on constellation size figures.
