# Space String (Space.IDC Computing Constellation): orbital data center program

> China (China), startup. Stage 5 of 7: Own satellite flown. STAR.VISION, one of the two operators, launched a pair of satellites it built, with onboard AI processing, on Jielong-3 on 2026-08-05; Hangzhou outlets describe a pair launched that day as the constellation's starting satellites. Edge class.

## Stage evidence

- STAR.VISION, one of the two operators, launched a pair of satellites it built, with onboard AI processing, on Jielong-3 on 2026-08-05; Hangzhou outlets describe a pair launched that day as the constellation's starting satellites. Edge class. Sources: [China in Space](https://www.china-in-space.com/p/uzbek-indonesian-satellites-launched)

## Key figures

## Approach

- Orbit: Layered dawn-dusk orbits, joined by inter-satellite laser links
- Architecture: More than 1,000 satellites in the long run: 720+ data satellites and 360+ compute satellites; full network targeted for 2035
- Power: Compute payload design peak power: G1 11.5 kW, G2 48 kW, G3 140 kW (company claim)
- Cooling: Not disclosed
- Compute: FP8 peak about 40 to 60 PFLOPS (G1), 160 to 310 (G2) and 460 to 1,000 (G3) (company claim)
- Customers: Not disclosed. Launch bookings on Gravity-1 and Ceres-2

## Milestones

| Date | Status | Confidence | Milestone | Sources |
| --- | --- | --- | --- | --- |
| 2026-08-05 | achieved | Reported | STAR.VISION pair launched on Jielong-3 Y12. Built by STAR.VISION with onboard AI pre-processing (China in Space, which names them as Uzbek and Indonesian Earth-observation satellites). Hangzhou outlets call a pair launched that day the constellation's starting satellites; the builder is reported differently by different outlets. | [China in Space](https://www.china-in-space.com/p/uzbek-indonesian-satellites-launched) |
| 2026-09-25 | achieved | Reported | Space String announced at the 5th Global Digital Trade Expo. More than 1,000 satellites, full network by 2035. | [Sohu (announcement)](https://www.sohu.com/a/1081902506_114984); [National Business Daily](https://www.nbd.com.cn/articles/2026-09-28/4593860.html) |
| 2026-09-26 | achieved | Reported | Agricultural Bank of China and ICBC sign RMB 5B credit lines each. Credit lines, not equity. | [21st Century Business Herald](https://m.21jingji.com/article/20260926/herald/1c884b26598bef4cc5bd45ab847f34fb.html) |

## Announced next steps (as the organisation stated them)

- Q4 2027: G1 verification satellite (11.5 kW compute payload). Sources: [Sohu (announcement)](https://www.sohu.com/a/1081902506_114984); [21st Century Business Herald](https://m.21jingji.com/article/20260926/herald/1c884b26598bef4cc5bd45ab847f34fb.html)
- 2035: Thousand-satellite network complete. Sources: [Sohu (announcement)](https://www.sohu.com/a/1081902506_114984)

## What to watch (SpaceNexus note, not a prediction)

Whether the G1 verification satellite flies in Q4 2027, and whether the operators publish what the August pair has computed.

## Funding

- 26 Sep 2026: Strategic credit lines from Agricultural Bank of China and ICBC (RMB 5B each), RMB 1B. credit availability, not drawn funding. Sources: [21st Century Business Herald](https://m.21jingji.com/article/20260926/herald/1c884b26598bef4cc5bd45ab847f34fb.html)

## Cautions

- English names are as reported by China in Space; no English name was found for 东方星链.
- All power and compute figures are company plans.
