The satellites were placed into orbit from Russia’s Vostochny Cosmodrome in a multi-payload launch that Iranian officials described as the country’s seventh satellite mission carried out using Russian launch vehicles.
“These satellites were designed and manufactured by Iranian scientists, and both government bodies and the private sector have been involved,” Iran’s ambassador to Russia, Kazem Jalali, said in remarks published ahead of the launch.
“Two of the satellites belong to the government and one belongs to the private sector, and our knowledge-based companies and universities are active in this field.”
Jalali said Iran had continued to advance its space capabilities despite international pressure. “Despite all the threats and sanctions that exist, we have something to say in this field.”
Iran’s space agency chief, Hassan Salarieh, said the launch reflected what he described as Iran’s standing among a small group of countries with end-to-end space capabilities.
“Iran is among 10 or 11 countries in the world that simultaneously possess the capability to design and build satellites, launch vehicles and the infrastructure for launching, receiving data and processing images,” he said.
Salarieh said Iran aimed to expand both the number and precision of its satellites. “What is necessary for us is increasing the number of satellites, improving their accuracy and quality, and developing different classes of satellites,” he said.

Iranian media identified the satellites as Paya, also known as Tolou-3, Zafar-2, and a prototype satellite called Kowsar-1.5. The spacecraft were launched alongside a large cluster of mainly Russian satellites into a sun-synchronous low Earth orbit.
Paya (Tolou-3), built by the Iranian Space Agency, is Iran’s heaviest Earth-observation satellite to date, weighing about 150 kilograms.
Iranian officials say it is capable of producing black-and-white images with a resolution of about five meters and color images with a resolution of around 10 meters, and is intended for applications including agriculture, water management, environmental monitoring and disaster assessment.
Zafar-2, developed by Iran University of Science and Technology, is also an Earth-observation satellite designed for mapping, environmental monitoring and tracking natural hazards.
Kowsar-1.5 combines imaging and internet-of-things capabilities and is aimed primarily at agricultural and farm-monitoring uses, Iranian officials say.
Jalali described Iran’s space cooperation with Russia as extensive and said Moscow’s experience had played a key role.
“Russia is advanced in the space field, including satellites, launch vehicles and satellite launches, and we have been able to transfer part of the technology and work together,” he said.
He also described the Soyuz rocket as highly reliable. “Before Russia’s relations with the West deteriorated, many Western satellites were launched using Soyuz,” Jalali said.
The launch also carried Russian Earth-observation satellites, internet-of-things platforms and university-built spacecraft, according to launch data, as well as satellites from partner countries including Belarus, Kuwait and Montenegro.
Iran says its space program is civilian and focused on scientific and economic goals, but Western governments argue that satellite launch technology overlaps with systems used to develop intercontinental ballistic missiles.
