Pakistan’s EO-1 launch on January 17, 2025 was an important space milestone. It gave the country its first indigenous electro-optical Earth observation satellite and strengthened local remote sensing capability. But the story did not end there. In the months that followed, Pakistan added more Earth observation assets, and in February 2026 it launched EO-2 to work alongside EO-1.
EO-1 marked a new stage
EO-1 was launched from Jiuquan Satellite Launch Centre in China and was built to support agriculture, disaster monitoring, land use planning, environmental analysis, and natural resource management. Its core value was not only the images it could capture. It also showed that Pakistan could design and build a modern electro-optical mission through its own engineering base.
It is important to state the milestone correctly. EO-1 was Pakistan’s first indigenous electro-optical satellite, not the country’s first indigenous satellite overall. Official SUPARCO records show that PakTES-1A and PRSS-1 had already been launched in 2018. That makes EO-1 a major step forward, but not the starting point of Pakistan’s entire satellite story.
Pakistan expanded Earth observation in 2025
New remote sensing satellite
The next big development came on July 31, 2025, when Pakistan launched a new remote sensing satellite from China. Official reporting said the satellite would deliver high-resolution, round-the-clock imaging and serve as a key part of an integrated Earth observation system. At the launch ceremony, Planning Minister Ahsan Iqbal called it Pakistan’s 4th Earth observation satellite and linked the mission to a broader national space roadmap that includes a Moon mission target for 2035.

That mission moved quickly from launch to operation. On August 16, 2025, APP reported that the satellite had reached orbit, established stable communication with ground stations, and started sending high-resolution images back to Earth. That mattered because it showed Pakistan was not only launching satellites, but bringing them into active service.
HS-1 widened imaging capability
Pakistan widened its observation toolkit again on October 19, 2025, with the launch of HS-1, the country’s first hyperspectral satellite. Unlike standard optical imaging, hyperspectral imaging captures data across hundreds of narrow spectral bands. That allows more detailed monitoring of crop health, water resources, pollution, land use, and urban change.
By October 23, 2025, the UN’s UN-SPIDER portal said EO-1 and the remote sensing satellite launched earlier that year were already operational. It also said HS-1 was in calibration and would become fully operational later in the year. By that point, the EO-1 story had clearly become part of a wider Earth observation network rather than a one-off launch event. 6
EO-2 now works with EO-1
The strongest new development arrived on February 12, 2026, when Pakistan launched EO-2, its second indigenous Earth observation satellite, from China’s Yangjiang Seashore Launch Centre. APP said the new mission would improve the continuity, coverage, and precision of Earth observation data for planning, governance, environmental monitoring, disaster response, and resource management.
A SUPARCO press release carried the next important detail. It said EO-2 was designed to operate in coordination with EO-1. Because the two satellites can observe Earth under different illumination conditions, they improve feature interpretation, change detection, imaging continuity, and analytical accuracy. That is the clearest reason this article now needs a new angle: EO-2 does not replace EO-1. It strengthens it.
Why the stronger satellite fleet matters
This stronger fleet gives Pakistan better tools for everyday state functions. Officials have tied the satellites to flood response, land mapping, food security, water resource management, urban planning, climate analysis, and infrastructure monitoring. The July 2025 remote sensing mission was also described as a support asset for CPEC and other national development projects.
The bigger takeaway is simple. EO-1 was a milestone, but it is no longer the whole story. Pakistan used that launch as a base for a broader Earth observation build-out in 2025 and 2026. With EO-2 now working alongside EO-1, the country’s remote sensing program has moved from a single breakthrough to a more capable and continuous national system.
