The Safir (Persian: سفیر‎, meaning "ambassador") is the first Iranian expendable launch vehicle able to place a satellite in orbit.[2] 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.[3][4]

The Simorgh is a larger launcher based on Safir technology, and sometimes called the Safir-2.[5]

Kavoshgar

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.[citation needed]

On 19 February 2008, Iran offered new information about the rocket and announced that Kavoshgar-1 used a two staged rocket.[6] The first stage separated after 100 seconds and returned to earth with the help of a parachute. The second stage continued its ascent to an altitude of 200 kilometres. However it was not intended to reach orbital velocity.[citation needed]

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.[7][8]

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.[citation needed]

Safir has made seven launches so far, putting 4 satellites into orbit.

Flight No. Date & Time (UTC) Payload Type Outcome Remarks
1 17 August 2008 Unknown; may be boilerplate Safir-1 Un­known US defense officials claimed the vehicle failed after first-stage powered flight; Iranian officials claimed that the launch was a suborbital test carrying a boilerplate satellite.[9][10]
2 2 February 2009 Omid Safir-1 Success First successful orbital launch of Safir making Iran the ninth country to develop an indigenous satellite launch capability.[11]
3 15 June 2011 Rasad Safir-1A Success Rasad-1 was launched on the maiden flight of the Safir-1B with increased thrust.
4 3 February 2012 Navid Safir-1B Success New configuration of the Safir carrier rocket, featuring a larger second stage with 20% more thrust.
5 Between 18 May and 21 June 2012 Unknown Safir-1B+ Failure Satellite imagery shows a blast scar on launch pad, suggesting that there has been a launch. No officials have confirmed a launch. It may have been either an engine test or rocket failure at high altitude.[5]
6 2 February 2015 Fajr Safir-1B+ Success First Iranian satellite with orbital maneuverability using cold-gas thrusters.
7 5 February 2019 Doosti (Friendship) Safir-1B+ Failure The Deputy Minister of Defense in Iran claimed a successful launch.[12] Research associates at the Middlebury Institute of International Studies claimed the launch failed at some point after liftoff.[13]
8 29 August 2019 Nahid 1 Safir-1B+ Failure Launch preparation accident.[14][15]
