Iran launches its Simorgh orbital rocket

11:11 am

Iran today announced it has successfully placed several small payloads into orbit, its Simorgh rocket lifting off from its interior Semnan spaceport.

The Simorgh carried what Iran described as an “orbital propulsion system,” as well as two research systems to a 400-kilometer (250-mile) orbit above the Earth. A system that could change the orbit of a spacecraft would allow Iran to geo-synchronize the orbits of its satellites, a capability Tehran has long sought.

It also carried the Fakhr-1 satellite for Iran’s military, the first time Iran’s civilian program is known to have carried a military payload.

This was Iran’s fourth launch in 2024, doubling the launch record it had set in 2023.

The leader board for the 2024 launch race remains unchanged:

127 SpaceX
59 China
16 Russia
13 Rocket Lab

American private enterprise still leads the rest of the world combined in successful launches 146 to 91, while SpaceX by itself leads the entire world, including American companies, 127 to 110.

Iran completes third orbital launch in 2024

10:17 am

Iran's spaceports

According to Iran’s state-run press and now confirmed by independent sources, Iran yesterday completed its third orbital launch in 2024, its new solid-fueled three stage Qaem-100 rocket lifting off on its second launch from Iran’s interior Semnan spaceport. No word on where the rocket’s lower stages crashed.

The payload was an engineering test satellite, which according to the Iranian press is operating as planned.

At the moment Iran appears to aggressively accelerating its civilian space program. It now has two functioning rockets, the Simorgh rocket, which placed three satellites in orbit in January, and the Qaem-100, its first launch taking place also in January. The country is also building a coastal spaceport near the town of Chabahar, as shown on the map to the right. Moreover, this third launch is the most the country has ever achieved in a single year. Until 2024, Iran had never launched more than once in any year.

And while these rockets and satellites do not appear to be military in nature, the technology development will certainly result in advances in Iran’s missile capabilities. The Qaem-100’s solid-fueled design is exactly what most ballistic missiles use, since it allows the missile to be stored fueled for long periods.

The leader board in the 2024 launch race remains unchanged.

91 SpaceX
38 China
10 Rocket Lab
10 Russia

American private enterprise still leads the rest of the world combined in successful launches 106 to 59, while SpaceX by itself leads the entire world, including American companies, 91 to 74.

Iran finally admits rocket launch on December 30th was a failure

5:33 pm

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.

Iran launches orbital Simorph rocket, does not reach orbit

3:09 pm

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.

Iran rocket fails to place satellite in orbit

8:44 am

The new colonial movement: According to their government sources, Iran today tried and failed to place a Earth imaging satellite into orbit with their Simorgh rocket.

The rocket carrying the Payam satellite failed to reach the “necessary speed” in the third stage of its launch, Telecommunications Minister Mohammad Javad Azari Jahromi said.

Jahromi said the rocket had successfully passed its first and second stages before developing problems in the third. He didn’t elaborate on what caused the rocket failure but promised that Iranian scientists would continue their work.

I wonder how much of a failure this launch is. If they were testing an ICBM capability, then the successful operation of the first and second stages would likely rank this as a success. And even if their main goal wasn’t ICBM testing, in the end they have done so, as they can apply what they learn here to all military missile technology.

Update: You can see video of the launch at this Iranian press story, along with other details about Iran’s space effort. I found the comments there most educational however. Here’s one sample: “Iran needs to use its space technology to fire invincible hyper-sonic missiles from space at the Jews in Israel.” The comments are all not like this, but there are enough to give you a sense of Iran’s social culture.

Video of Iranian launch today

9:22 pm

The Iranians have released video of today’s rocket launch.

I’d love a translation of what the crowd is chanting. I would also encourage the engineers in my readership to look at this and tell me if the launch looks right, and if there is any way to judge whether it is an rocket for orbital satellites or a missile. We still have no evidence the rocket successfully put anything in orbit.

Meanwhile, the Trump administration has called this launch a breach of a UN resolution forbidding Iran from developing ballistic missiles.

Iran launches satellite

10:15 am

According to its state news services, Iran today successfully launched a satellite into orbit.

Iranian state television described the launch as involving a “Simorgh” rocket that is capable of carrying a satellite weighing 550 pounds. The state media report did not elaborate on the rocket’s payload. “Simorgh” means “phoenix” in Farsi.

The website YJC.ir, which is affiliated with Iranian state television, as well as the semi-official Fars news agency, also reported the launch on Thursday, saying it was successful.

No information as yet on the payload. That the launch itself has not yet been recognized by websites that track these things, it is possible the launch was not successful, but they do not want to admit it.

Iran to launch satellite?

12:26 pm

Does this make you feel safer? Iran is preparing to launch a new ballistic missile capable of placing satellites in orbit.

The Simorgh rocket is a new development not seen previously. Its launch would also be a violation of a UN resolution forbidding Iran to do such research, but who cares about that? It wouldn’t be violation of the great deal Obama negotiated for us with Iran, a deal that they themselves never endorsed.
