Iran launched three remote-sensing satellites—Tolou-3, Zafar-2, and Kowsar-1.5—into orbit on Sunday from Russia’s Vostochny Cosmodrome. The satellites were carried aboard a Soyuz-2.1b launch vehicle as part of a multi-payload mission. This marks the seventh time Iran has used a Russian rocket for satellite deployment, according to the Mehr news agency. Hassan Salarieh, head of Iran’s Space Agency, said the launch signals a bright future for the country’s space sector and is the first instance of Iran sending multiple satellites into space simultaneously. Among the satellites, Tolou-3 is Iran’s heaviest and most advanced observation satellite to date, weighing 150 kilograms. About 80 percent of its components were manufactured domestically, representing a major step toward the localization of satellite cluster technology. Iran also plans to launch its first telecommunications satellite cluster, named “Shahid Soleimani,” next year, continuing its efforts to expand national space capabilities.
