Iran is set to place three domestically built satellites into low Earth orbit on Sunday in a multi-payload launch from Russia, marking another step in Tehran’s expanding space program, which Western governments say relies on technologies applicable to long-range missiles.
Iranian media said the satellites would be launched at 1648 local time (1318 GMT) aboard a Russian Soyuz rocket from the Vostochny Cosmodrome in Russia’s far east. The payload includes Paya, also known as Tolou-3, Zafar-2 and a prototype satellite known as Kowsar-1.5.
Paya (Tolou-3) is Iran’s heaviest Earth-observation satellite to date, weighing about 150 kg, with imaging resolution of around five meters for black-and-white images and about 10 meters for color imagery, Iranian officials have said.
The satellite, made by the Iranian Space Agency, is designed for applications including agriculture monitoring, water resource management, environmental monitoring and disaster assessment.
Zafar-2, developed by Iran University of Science and Technology, is also an Earth-observation satellite intended for mapping, environmental monitoring and tracking natural hazards.
The Kowsar-1.5 satellite is a combined platform integrating imaging and internet-of-things capabilities, aimed primarily at smart agriculture and farm monitoring.
The Iranian satellites will be launched alongside a large cluster of mainly Russian spacecraft into a sun-synchronous low Earth orbit.
According to launch data, the mission also includes Russian Earth-observation satellites such as Aist-2T and Zorkiy-2M units, multiple Marafon and SITRO satellites designed for internet-of-things and ship-tracking services, as well as university-built and technology demonstration satellites from Russia and partner countries including Belarus, Kuwait and Montenegro.
Iran says its space activities are civilian and focused on scientific and economic uses, though Western governments argue that satellite launch technologies overlap with those used for long-range ballistic missiles.
Iran has increasingly relied on Russian launch services in recent years, even as it develops domestic launch sites and heavier rockets.
