Recently, areas like Beijing, Tianjin, and Shanghai have stepped up their deployment of space-based computing power. They've done this by setting up research institutes, innovation hubs, and partner programs focused on the space computing ecosystem. Space computing power means placing computing, storage, and smart data processing capabilities in space. This setup leans on the computing abilities of satellites and constellations in low-Earth orbit. It boasts benefits like worldwide coverage, efficient data processing right in orbit, robust network resilience, and eco-friendly sustainability. The main perk? It brings computing power nearer to where data is generated. This is crucial for applications that ground-based computing can't handle well, like disaster monitoring and emergency response, which need ultra-fast real-time performance.

The road to developing space computing power isn't without hurdles. Four big ones stand out: computing capacity, communication, heat management, and energy. To overcome these, we need advances in high-performance, radiation-hardened computing chips, fast and stable laser links between satellites and between satellites and the ground, cooling systems for extremely high heat levels, and large-scale new energy power systems.

To foster a thriving industry, we must concentrate on three fronts: crafting a top-down design for a unified space-ground computing power network, achieving key technological breakthroughs, and showcasing practical applications in key sectors. It's vital to follow a coordinated top-level strategy, pursue differentiated growth, make technological leaps, and ensure standardized management. This way, we can create a healthy industrial ecosystem for integrated space-ground computing.
