Iranian Space program

[sha ah]

So Iran send 3 "research devices" into space on the one Simorgh rocket. With a 350 kg maximum payload capacity for Simorgh, that would mean that 3 "micro" sized satellites or research devices were sent into space.

So now that the Iranian space program is well funded again, hopefully we will see serious progress within the next few years. The Iranian government is promising great achievements this calendar year, but that remains to be seen.

Yes ...Space Program is back..

Iran successfully launches research satellite into space
A handout picture released by Iran's Defense Ministry on July 27, 2017 shows a Simorgh (Phoenix) satellite rocket at its launch site.
Iran has successfully launched a domestically-built satellite carrier rocket, named Simorgh (Phoenix), sending three research devices into space, the Defense Ministry says.
“In this space research mission, for the first time, three research devices were launched simultaneously at an altitude of 470 kilometers and at a speed of 7,350 meters per second,” a spokesman for the ministry, Ahmad Hosseini, said on Thursday.
He said the space center’s components performed flawlessly and the stages of the satellite carrier’s launch took place according to plans. “Finally, the intended research goals [of the mission] were fulfilled,” Hosseini said.
Hosseini said the launch followed several achievements in the Islamic Republic’s civilian space program.
In 2017, Iran’s Imam Khomeini Space Center successfully launched the Simorgh carrier with a mission of putting satellites into the orbit.

Iranian minister promises 'good news' on launch of satellites
Iran will have "good news” about its launch of satellites before the end of the current Persian year in March 2022, the country
“We will speed up work so that we can become one of the six countries that can launch satellites into the GEO (geostationary) orbit,” he added.
The United States has expressed concern that Iran’s satellite launches are part of an effort by the Islamic Republic to develop ballistic missiles capable of delivering nuclear weapons.
Iran, which has long maintained its nuclear program is entirely civilian in nature, says its satellite launches and rocket tests do not have a military component.

How long can you people be this disingenuous or ignorant?

Rouhani's government disolved in August and this is December.

You want to believe that this is due to current government and not project that started during previous government.

You hate Rouhani so much that you have to blatantly lie in order to praise current administration and pretend past launches didn't happen.

That is not what he says...sometimes all it takes is to re-organize and re-focus the efforts while at the same time remove the traitors from the scene... and yes I can assure you that there were traitors in that organization...Every Engineer or technician in the Space agency now is assured that their efforts mean something..sounds like a slogan but I know how a team works when they have faith in their project...some thing that was missing in that F*ck head Rouhani .

Launch highly likely failed. Final velocity achieved by Simorgh was only 7.35 km/s. For 470km circular LEO at least 7.65 km/s of injection velocity is needed.

With a 350 kg maximum payload capacity

Not to nitpick but Simorgh cannot launch anywhere near 350kg in its current config. Even with kick stage maximum payload capability is probably below 200kg. The garbage engines on the second stage are to blame.

You may want to notify the Iranian Space Agency of your finding which clearly they missed.

I will believe it when the satellites are tracked in orbit. So far nothing has entered orbit. Chances are the payloads are laying at the bottom of the indian ocean right now instead of in orbit.

Another failed test but they seem to be getting close to success. The only thing that changed this time is that at least we didn't lose a satellite.
Can anyone explain why they do not add a third stage to Simorgh? What would be the downsides of that and why are they reluctant to do it?

...yet no evidence ever provided for existence of alleged traitors to be dragged out which if there were would have saved face for Iranian space program.

 

[sha ah]

Perhaps the intension was not to put a satellite into orbit but rather to conduct a test on the platform in some way ? We cant be sure but the more tests they conduct the better.

The whole point of sticking to the traditional four engine SLV is low expense and ease. If they expand the design which is complex but low cost, significant changes are needed down the road.

Lots of failures for a low cost SLV is worth it.

When it succeeds they can make Simorgh like they make Pride or Emad or Ghadr. A lot for cheap price.

 

[QWECXZ]

What was the payload?

There were 3 payloads for a total weight of 350 kilograms apparently. They didn't release any info on the payloads though. And no satellite was named either. So, this was probably just a test before the real launch in February.

So, you are basically saying that Iran is trying to develop its missile program beyond the 2500km range limit under the disguise of a civilian space program?

Because I don't see why we need a low cost SLV at the expense of multiple failed launches and falling behind our schedule. After all, how many spaces launches are we going to have with Simorgh to make it low cost? It's not like we're going to need many of these SLVs in future.

You may want to share your beliefs with the ISA as well. I’m sure they will be taken with due seriousness.

 

[jauk]

This launch had clear test objectives given enhancements of the rocket. That doesn’t exclude the hope of successful insertion whose success is unclear. That said, the ISA has poorly messaged this. If it’s a test then say it.

Regardless, at this stage, the frequency of launches is far more important than their success. Note SpaceX, albeit a successful program, has a high frequency of failures. Besides, frankly, I don’t see SpaceX and their primitive pencil landings as all that anyway . China is what has the more exciting story today.

Last time rocket delivered payload to desired orbit...but kick off booster failed to speed up satallite so it can reach stab orbit
Not from this lunch..but it gives perspective
