Space: The Growing Iranian Space Program

Iran recently announced that their scientists and engineers had built two new space satellites. This was done at a university. One of the satellites was for communications, specifically for supporting satellite phones that use encryption. Just the thing Quds Force requires for its agents overseas. Quds Force supports Islamic terrorists that are allies of Iran. The second satellite can take photos and transmit them back to earth. This one is capable of 100 meter resolution (pictures taken allow the identification of any object 100 meters wide or larger.) You can get higher resolution photos on the web. But the point Iran is making here is that it is becoming less and less dependent on other nations for space satellites. The many sanctions against Iran make it increasingly difficult to buy satellites from foreign manufacturers so Iran must learn to build its own or do without.
 
When Iran could buy foreign satellites they did so and paid for foreign rockets to launch them. This is how Iran launched its first satellites in 2005. This was the Sina-1 communications and photo-reconnaissance satellite that was capable of performing espionage, especially against Israel. Launched in October 2005 on a Russian rocket, the satellite was described as being used for scientific purposes only. With a three year lifetime, the Iranians described camera equipment as capable of 50 meter resolution (pictures taken allow the identification of any object 50 meters wide or larger.) This is not military grade resolution. You can get better stuff from Google Earth.
 
Russia built the 110 kg (375 pound) Sina-1, and is unlikely to have secretly provided higher resolution (and much more expensive) camera gear. Besides, you can’t get high res equipment into a satellite of that size. Russia received a $132 million contract with Iran, to build and launch this satellite, so the Russians kept quiet about the Iranian claims. The “spy satellite” claim by Iran is apparently for domestic consumption, another attempt to show the Iranian people that the country is getting its money’s worth and to buff the country’s anti-Israeli reputation.
 
Even before Sina-1 Iran has been caught using spies to steal Western satellite technology. They have had some success with this espionage and smuggling effort. Iran launched its second satellite in 2008 using a Chinese rocket. In 2012, for the third time in the previous three years, Iran put a satellite (Navid) into orbit using one of its own rockets. Navid was a 50 kg (110 pound) photo satellite with an estimated lifespan of 18 months. Navid was also used for testing other functions, like communications. Iran launched the Rasad-1 photo satellite in 2011. The first Iran launched satellite, Omid, was called an experimental telecommunications effort, and it went up in 2009.
 
Since 2005 Iran has been trying to get an Italian firm to let go of a $10 million Mesbah-1 telecommunications satellite built for Iran. Shipment of the satellite was halted when new sanctions were slapped on Iran, which made the paid-for satellite illegal for Italy to export. When Iran made the Mesbah-1 deal, the 75 kg (175 pound) satellite was to be launched using a Russian rocket. But now Iran has rockets that can launch small satellites, and wants to get their hands on Mesbah-1 and launch it themselves. But that won't happen with the sanctions. And even more recent sanctions make it illegal for Russia to launch the Mesbah-1. Since the Mesbah-1 was somewhat low-tech, Iran went ahead and built one itself, which it plans to launch on an Iranian rocket this year, and hopes their version (of both the rocket and the satellite) will work.
 
In 2009, using a modified Shahab 4 ballistic missile, Iran put a crude satellite into low earth orbit. This was done to coincide with the 30th anniversary of their Islamic revolution. The satellite was described as a "communications satellite", but it was actually nothing more than a transponder, giving off a signal that could be tracked. What Iran has done is carry out the same kind of early satellite launches Russia and the United States did in the 1950s. Iran then announced that they were building more satellites and they have done that. But given the level of technology they have access to, these have been low capability birds, launched in to low orbit and have short lifetimes.
The Iranian launch is similar to the Russian Sputnik launch of 1957, which was the first satellite ever put in orbit. The U.S. followed in 1958. Since then, eight other nations, including Iran, have done the same. Ukraine was the last to do so, in 1995. Israel launched its first satellite in 1988. France launched its first satellite in 1965, Japan and China in 1970, Britain in 1971, and India in 1980.
 
Iran is continuing to combine ballistic missile and satellite launcher development. Most of the larger ballistic missiles, especially ICBMs, can launch satellites. The U.S. and Russia have used retired ICBMs for this. Iran is following the same path, sort of.

Unmanned Russian rocket explodes on takeoff


An unmanned Russian carrier rocket exploded on takeoff at the Baikonur cosmodrome in Kazakhstan, releasing 600 tonnes of highly toxic fuel into the air in images broadcast live on television.

Spectacular footage showed the Proton-M rocket veering off its trajectory just seconds after its 6:38 am (0238 GMT) launch, before erupting into a ball of flames and unleashing clouds of noxious black smoke.

The Russian space agency Roskosmos, citing preliminary information, said the accident caused no damage or casualties.

"It seems something is going wrong," said a television commentator during the live coverage of the launch. "Something is wrong. It seems it will be a catastrophe," said the presenter, his voice trembling, shortly before the rocket exploded.

The rocket was supposed to take three Russian Glonass-M navigation satellites into space.

"A rocket carrier fell to the ground and exploded on the territory of the cosmodrome," the space agency said in a statement, adding that the rocket fell on the territory of the Baikonur cosmodrome which Russia leases from ex-Soviet Kazakhstan.

The space agency said that during the accident, which took place 10-15 seconds after takeoff, toxic rocket fuel was released into the air.

Kazakh officials said the fumes that may present a danger to the local population.

A Roskosmos spokesman could not immediately say whether people living near the crash site were being evacuated.

But residents of several towns close to the cosmodrome including Baikonur were requested to stay indoors and keep their windows shut, a spokeswoman for the Kazakh emergencies ministry, Kristina Mohamed, told AFP.

The rocket carried 600 tonnes of kerosene, heptyl and amyl which are highly poisonous components of rocket fuel, said the head of the Kazakh space agency, Talgat Musabayev.

"A smoke cloud has now been formed out of burnt heptyl," head of the emergencies ministry in Kazakhstan, Vladimir Bozhko, told a government meeting in Astana.

"It is now located above the territory of the cosmodrome, the speed of the wind is 2.6 metres (per second)," he said, adding the cloud could move beyond the Baikonur cosmodrome.

Bozhko was quoted as saying that according to preliminary information the accident was caused by a malfunction of a first-stage engine.

Sending the first man into space in 1961 and launching the first sputnik satellite four years earlier are among key accomplishments of the Russian space programme and remain a major source of national pride in the country.

But more recently, Russia has suffered several major setbacks in its space programme, notably losing expensive satellites and an unmanned supply ship to the International Space Station.

The most recent disaster brought to memory a rocket explosion at the same Baikonur cosmodrome in 1960 when a prototype rocket exploded on the launch pad and released the highly poisonous rocket fuel known as the "devil's venom."

During the 1960 accident, which the Russian space agency has called a veritable "inferno," 126 people were burned alive or vaporised altogether, while others died of noxious fumes or succumbed to burns later.

The Soviet Union, which was locked in an arms race with the United States, imposed total secrecy over the disaster, and the files were only declassified in the 1990s.

Iran to launch satellite to space by solid-fueled missile




Chief Commander of Iran's Revolutionary Guard Corps (IRGC) Mohammad Ali Jafari announced that Iran will launch new satellite to GEO orbits in space by solid-fueled missile, Fars reported.

Jafari said that as part of marking the first anniversary of IRGC general Hassan Tehrani's death, Iran will be launching its satellite into space by a solid-fueled missile.
One year ago, IRGC General Hassan Tehrani got killed as a result of an explosion occured during the missile test, that was supposed to test the solid-fueled rocket carrying a satellite to space.

"Iran has not launched a over 100-kg satellite (by liquid-fueled missile) to GEO orbit so far, but we planned this project and developed after Tehrani's death," he added.
Iran has already sent three satellites into space. On February 3, the country successfully launched its third domestically manufactured satellite, named the Navid (Promise), into orbit.

The Safir one satellite carrier rocket was used to launch the Navid research satellite.

The commander, Gen. Hassan Tehrani Moghaddam, was a major figure in IRGC efforts to build long-range missiles, who died reportedly during a test of missile in a military base last November.
