Iran is set to launch its 4th home made satellite into space.
It is the 2nd satellite designed by SaIran (Iran Electronics Industries [IEI]) ready for launch after successful mission of Omid (hope) satellite. Setting out a coherent plan for achieving space high tech and assuring accuracy/reliability, Iranian aerospace organizations have operationalised a comprehensive and integrated step by step approach for technology promotion and consolidation according to which upgrades are unveiled during each mission. Omid mission proved Iran's capability to successfully carry and orbit a satellite; Rasad (observer)-1 had been already shot into space showing Iran's acquisition of live satellite imaginary technologies as well as development of a gravity gradient boom. Domestic standards were finally set out for satellite design and manufacture methodologies/procedure; large number of sensors were designed and installed during Navid (promise) space mission; also, reliability of Safir 1B satellite-carrier rocket was approved given the fact that Navid payload is twice heavier than Omid.
Now, the latest Iranian satellite changes its elliptical motion into a circular orbit using nitrogen thrusters, capsules containing highly pressurized nitrogen gas at 300-400 bars; at apogee, the thrusters ignite and alter LEO into a 400km high circular orbit. Thanks to latter achievement, Fajr orbit lifetime exceeds 18 months, significantly longer than former Iranian SVs. The satellite enjoys built in-live imaginary and several new hardwares. Fajr weighs approximately 60kg. Unofficial start date of the project was May 22nd, 2009; operational prototype was delivered on 21st April, 2011 to undergo pre-launch tests. The project was finalized within less than 18 months.

Like Navid, Safir 1B will orbit Fajr; the carrier rocket has upgraded engines and more advanced fuel compared to early Safir rockets.
Iranian defense minister told that the country will launch Fajr satellite into orbit on 23rd May during a press briefing.

The Iranians are surely impressive: their rocket current has a record of 3 successful launches in 4 flights, already better than the Falcon 1! Maybe they should start a commercial Islamic nano-satellite launch service? :p

Rumors have circulated that the "delay" in May could have been related to a launch failure! Here is a quote on the October issue of Jane's Intelligence Review:

Nick Hansen said:
Kavoshgar-5 was more ambitious and was to carry a live primate. Initially scheduled for some time in September 2011, further announcements narrowed the launch date to between 7-9 September. After these dates passed, no further announcements were made for almost a month when, on 12 October 2011, Deputy Minister of Science Mehdinejad-Norui stated: "The launch was not publicised, as all of its anticipated objectives were not accomplished and Iran indefinitely postponed plans to send a live monkey into space." The report was tantamount to an admission of failure. Several announcements in May 2012 indicated that the Iranian authorities aimed to try again in August or September 2012, although at the time of writing no further launches have occurred.

Nick Hansen said:
The most likely explanation for the official silence is that the Fajr failed to achieve orbit, although on 1 August 2012, Hamid Fazeli, Head of the Iranian Space Agency, stated that it would be launched in "two to three months". This would most likely be a copy of the one that appears to have failed in May 2012, with the delay between launches needed to establish why the initial attempt failed and prepare and ready another Safir-1B SLV and Fajr satellite for launch.

In addition, the Kavoshgar-5 research rocket (again, believed to be a copy of the one that failed in September 2011) was scheduled for launch in late August or September 2012. These launches would be the second attempts for both missions. Regardless of Iran's individual launch successes or failures, the pace and scale of these efforts have all been underpinned by an unrelenting drive to advance the country's rocket capabilities, as shown by the frequency of such high-profile launches and continued aggressive construction at their pre-eminent space launch centre.

The article also have photos by commercial imaging satellites that compares before-and-after photos showing evidence of burn marks at the launch pad claimed to be characteristic of a normal Safir lift-off. So maybe the Iranians have to launch a spare satellite later on? We will probably not know what (or even when) happened in late May for some time, but this is worth pondering on.

Jane's photo does not contain a good resolution, but it may because of a static engine test, if there is a really blast sign,... ;) and in a lower probability a failure.. :thumbup:
the main question is: if it was a launch, why no coverage by western news and broadcast on that time?

I'm gonna go out on a limb and say that the Iranian Space Program, like most of Iran, is less than welcoming to Western Media outlets...

Boy, is that an understatement!!!

Given Iran's history pertaining to Western media personnel investigating social irregularities (wrt Zahra Kazemi), and their penchant for arresting and extortion of western-based businessmen, even if one western-based reporter showed up to cover some aspect of Iran's space efforts they would probably be immediately arrested for expionage ... assuming they were invited in the first place.

US & NATO have had a large number of long range radars around IRAN. many of them are specially related to Ballistic Missile Defense systems, such as: AN/SPY-1 (Aegis system), AN/TPY-2, maybe SBX &... so if it was an exact launch and failure, they knew it and the failure matter was such as a happiness carnival for western media... something happend about North Korea...

hey Galactic Penguin SST! thanks for your post here:
http://forum.nasaspaceflight.com/index.php?topic=11734.420

Jane's new photo clearly shows a failure... :facepalm:
Iran,s space technology is really young and lots of failures are possible.

Well it seems to be a SEPARATE failure from the one in May....... that makes two known failures for Iranian rockets in 2012!

Believe it or not, the reliability of the Safir rocket is still better than the Falcon 1..... :rofl:

Safir launch with Fajr, February 2, 2015

Iranian state news as well as RIA Novosti are reporting that the "Fajr" ("Dawn") satellite was launched atop a Safir rocket at 09:30 GMT on February 2, 2015. The satellite appears to be working as expected according to other news sources.


Edit: Thanks for moving this into the correct thread.

Looks like the Iranians are back in action after several possible launch failures (note "possible" since they aren't clear if they are aimed at orbit) since the last successful satellite went into orbit exactly 3 years ago. I wonder if their microsat delivery service is better these days? :hmm:

BTW I have been asking the OP owner of this thread to add in more info about the rocket and satellite - let's see what he could add here. :tiphat:

Well, then. Congrats to the Iranians for joining the spaceflight club!

Let's just hope it's not just R&D for something more... militaristic. :shifty:

Errr this is their 4th satellite placed in orbit - the first one happened exactly 6 years ago. ;)

But it might be their first satellite with a lifespan of over two months, if everything goes well so that's definitely an achievment!:thumbup:
