Iran Satellites Launch from Russia’s Vostochny Cosmodrome
The Iranian satellite launch carried out this weekend from Russia adds another data point to the country’s steadily expanding space program. Three domestically developed satellites were successfully deployed into low Earth orbit from Vostochny Cosmodrome, with Iranian authorities confirming accurate orbital insertion and stable early operations.
Iranian satellite launch marks coordinated multi-spacecraft mission
The launch took place on Sunday, December 28th, 2025, in the Iranian evening time and included Zafar-2, Paya, and the second iteration of the Kowsar satellite. All three platforms are designed for Earth observation and data transmission, supporting civil and environmental monitoring rather than communications or navigation.

According to Iranian officials, the satellites were injected into their target low Earth orbits without anomalies, and initial system checks were completed shortly after separation.
Signal confirmation after Iranian satellites launch
Within hours of deployment, Iran confirmed successful reception of the first telemetry signals from all three spacecraft. The country’s communications and IT minister stated that multiple ground stations received data simultaneously, indicating stable links and healthy onboard systems.
Signal acquisition is a key post-launch milestone, as it confirms that power, attitude control, and communications subsystems are functioning as intended. With this step completed, the satellites can now move into routine monitoring, orbit stabilization, and mission commissioning.
Zafar-2 was developed at Iran University of Science and Technology, while Paya originated from Iran Electronics Industries’ aerospace division. Kowsar-1.5 was built by OmidFaza, a private Iranian firm positioned as a knowledge-based technology company. Together, the mission reflects a mixed academic, state-industrial, and private contribution model.
Precarious political climate
The launch also comes at a politically sensitive moment for Tehran, with widespread domestic protests and ongoing economic strain. Against that backdrop, the successful deployment and early signal acquisition underline Iran’s determination to keep its civil space program on schedule despite internal and external pressures.
Iranian officials have framed the mission as part of the country’s civilian Earth-observation program rather than as a communications or navigation effort. In practical terms, the launch adds to a sequence of recent space activities carried out under international sanctions and using a mix of domestic development and foreign launch infrastructure.
Earth-observation focus and practical use cases
The three satellites are intended for imaging and environmental data collection. Applications cited by Iranian sources include forestry oversight, agricultural assessment, climate analysis, and natural-resource management. In agricultural contexts, such data can be used to assess soil moisture, crop health, and weather-related risk, allowing more precise use of water and fertilizers.
While such capabilities are standard for Earth-observation satellites globally, Iran continues to emphasize their economic relevance, particularly in reducing yield uncertainty and stabilizing pricing in domestic agricultural markets.
Further launches planned in 2026
Following the Iranian satellite launch, the head of the Iranian Space Agency confirmed plans for additional missions in late February. These are expected to use domestically developed launch vehicles and may originate from new space centers under construction in Chabahar, on the Indian Ocean coast, and near Salmas in north-west Iran.
Iran has stated an ambition to conduct five to six launches per year, supplemented by missions from foreign spaceports, with higher cadence planned beyond the next Iranian calendar year.

The launch demonstrates Tehran’s intent to maintain launch continuity despite sanctions, while gradually shifting more activity to domestic infrastructure.
