The Safir (Persian: سفیر, meaning "ambassador") is the name of the first Iranian expendable launch vehicle that is able to place a satellite in orbit. The first successful orbital launch using the Safir launch system took place on 2 February 2009 when a Safir carrier rocket placed the Omid satellite into an orbit with a 245.2 km (152.4 mi) apogee.
A sub-orbital test flight, named Kavoshgar-1 (Persian: کاوشگر ۱, "Explorer-1"), was conducted on 4 February 2008, as announced by state-run television. A launch on 25 February 2007, may also have been of the same type. The first flights carried instruments to measure the higher atmosphere. The rocket launched on 4 February 2008 was a liquid-propellant-driven rocket, probably a derivative of the Shahab-3, that reached an altitude of 200–250 km in space, and successfully returned science data according to the Iranian News Agency.
On 19 February 2008, Iran offered new information about the rocket and announced that Kavoshgar-1 used a two staged rocket. The first stage separated after 100 seconds and returned to earth with the help of a parachute. The second stage continued its ascent to the altitude of 200 kilometres. However it was not intended to reach orbital velocity.
Earlier reports by the Iranian News Agency suggested that Kavoshgar-1 used a three staged rocket with the first stage separating after 90 seconds and the rocket reaching an orbit between 200 and 250 kilometres.
The successful development and launch of a sounding-space-rocket was already announced a year earlier, on 25 February 2007. It is unknown if the sounding rocket launched on 25 February 2007, and the rocket launched on 4 February 2008, are of the same type.
On 17 August 2008, Iranian officials reported that a Safir was launched successfully without a payload, in preparation for the launch of Iran's first indigenously launched satellite, Omid. Reza Taghizadeh, head of the Iranian Aerospace Organization, told state television "The Safir (Ambassador) satellite carrier was launched today and for the first time we successfully launched a dummy satellite into orbit".
According to an American official, "The vehicle failed shortly after liftoff and in no way reached its intended position." However, the video of the liftoff of the rocket was shown on the Iranian state television for several minutes. Iranian officials released a statement denouncing the allegations as propaganda and stated that Iran would soon launch the Omid satellite. Iran indeed launched the satellite on 2 February 2009, less than six months later.
On 2 February 2009, a Safir rocket conducted Iran's first orbital launch, with the Omid satellite. The two-staged launch vehicle was 22 m long with a diameter of 1.25 m, weighing about 26 tonnes. The 27 kg Omid satellite was launched into an orbit with a 245.5 km perigee and 381.2 km apogee. The evidence is mounting that Safir-1 was more powerful and advanced than initially thought.
On the maiden flight of the Safir-1B rocket from a launch site in Semnan Province, Iran's third indigenous satellite, the 15.3 kg Rasad 1 was launched. The launch occurred at approximately 09:14 UTC on 15 June 2011 with the spacecraft reaching orbit several minutes later.
