One day after implying that the test launch of Iran’s Simorgh orbital rocket on December 30th was actually a suborbital flight and was a success, that same official admitted yesterday that this was not true, that the plan had been to put three satellites in orbit, and that the launch was a failure.

Ahmad Hosseini, an Iranian defense ministry spokesman, revealed that the rocket failed to put its three payloads into orbit after the rocket was unable to reach the required speed, according to the news agency.

“For a payload to enter orbit, it needs to reach speeds above 7,600 (meters per second). We reached 7,350,” he said in a documentary broadcast on state TV.

It was Hosseini who claimed the launch was a success the day earlier, implying that the low speed was because the flight was intended to be suborbital. Either he knows nothing about rocketry (very likely), or is merely a mouthpiece who was ordered to change his story when the first story was laughed out of the room (also very likely).

The article at the link focuses on France’s condemnation of the launch, claiming it was a ballistic missile.

France’s foreign ministry said the launch was in breach of UN Security Council resolutions, Reuters reported. “We call on Iran not to launch further ballistic missiles designed to be capable of carrying nuclear weapons, including space launchers,” the ministry said.

Simorgh however is not a ballistic missile. Everything I have read about it suggests it is designed to put payloads in orbit, not deliver bombs to other parts of the globe. A ballistic missile is technically a very different thing. It usually uses solid rockets which can be stored for long periods and launched at a moment’s notice. Simorgh uses hypergolic fuels which — though they can be used on ballistic missiles — are rarely used for that purpose because of their toxic nature.

At the same time, these facts about Simorgh should not make us think Iran is not a threat. If you can develop the manpower and technical know-how to built an orbital rocket, you will also have increased your ability to build missiles. Iran is without doubt working to develop both.

According to Iran’s state run press, it successfully launched its orbital Simorgh rocket on a test suborbital flight today, carrying three payloads to an altitude of 292 miles.

Ahmad Hosseini, an Iranian defense ministry spokesman, said the satellite-bearing rocket named Simorgh, or “Phoenix,” had launched the three cargoes at an altitude of 292 miles (470 km) and at a speed of 7,350 meters (4,5 miles) per second. “The intended research objectives of this launch were achieved,” Hosseini said, in comments broadcast on state television.

“This was done as a preliminary launch … we will have an operational launch soon,” the spokesman added, without further clarifying whether the devices had successfully entered Earth’s orbit.

In 2020 Iran completed an orbital launch using a mobile launcher, which probably used a different solid rocket instead of Simorgh.

However, since Simorgh is intended as an orbital rocket and it did did not reach orbit this time strongly suggests the rocket failed. Since the Iranian press provided images of the rocket in flight soon after launch, the failure possibly occurred at first stage separation followed by ignition of the second stage, a critical moment in a launch where failures often occur.

No matter. Whether it failed or functioned exactly as planned, this launch will provide Iranian engineers valuable information for that inevitable successful orbital flight.

As an orbital rocket designed to launch satellites, Simorgh actually poses less of a threat than that mobile launcher from 2020. Simorgh isn’t really a missile designed to launch bombs. It takes too long to fuel, and its launch site is vulnerable. The mobile launcher used in 2020, likely using solid rockets, is far more dangerous.
