Iran on Sunday claimed it has successfully launched three satellites into space. The state-run IRNA news agency said the launch involved the successful use of Iran’s Simorgh rocket. It is the latest development in its program about which the West feels improves its ballistic missiles.

Iran’s state TV named the launched satellites Mahda, Kayhan-2 and Hatef-1. As per its description, the Mahda is a research satellite, while the Kayhan and the Hatef are nanosatellites focused on global positioning and communication respectively.

Iranian state television released footage of the nighttime launch for the Simorgh rocket. Expert analysis of the footage showed that it took place at the Imam Khomeini Spaceport in Iran’s rural Semnan province.

“The roar of the Simorgh (rocket) resonated in our country’s sky and infinite space,” said Abbas Rasooli, a state TV reporter, in the footage.

The Simorgh is a part of Iran’s civilian space program. It is a two-stage, liquid-fueled rocket designed to place satellites into a low Earth orbit. In recent years, the Simorgh, or “Phoenix,” rocket had suffered failures.
