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 apogee.〔(【引用サイトリンク】title=OMID Spacecraft - Trajectory Details )〕〔(【引用サイトリンク】title= The Threat )〕 ==Kavoshgar== A sub-orbital test flight, named ''Kavoshgar-1'' ((ペルシア語: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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Safir (rocket)」の詳細全文を読む スポンサード リンク
