Previous Iranian satellites

Omid was the second Iranian satellite to be placed into orbit. A previous Iranian satellite, Sina-1, was built and launched for Iran by Russia in 2005.

Test launch

Speaking at the opening of a new space centre on 4 February 2008, President Ahmadinejad announced that Omid would be launched in "the near future". On 17 August 2008, Iranian officials reported that they performed a test of the satellite carrier; they broadcast footage of the Safir rocket launch in darkness.

According to an American official, "The vehicle failed shortly after liftoff and in no way reached its intended position."

Orbit

The satellite was launched southeast over the Indian Ocean to avoid overflying neighboring countries and was placed into an orbit with an inclination of 55.5 degrees, with a perigee of 246 km, an apogee of 377 km, and a period of 90.76 minutes.

End of mission

Omid was reported to have completed its mission without any problems. It completed more than 700 orbits over seven weeks.{{cite news|title=Iranian satellite completes mission: state TV|url=https://www.reuters.com/article/us-iran-satellite/iranian-satellite-completes-mission-state-tv-idUSTRE52I34P20090319|date=March 19, 2009|publisher=Reuters |access-date=January 28, 2023}} According to U.S. Strategic Command, the Omid satellite re-entered Earth's atmosphere on 25 April 2009, during an 8-hour window centered on 0342 UT. The most likely re-entry location was over the south Atlantic Ocean, east of Buenos Aires, Argentina. No sightings were reported. The rocket body from the launch, which had also entered orbit, re-entered the atmosphere 31 May 2009.

Further launches

Iran launched Rasad 1 on 15 June 2011, orbiting for three weeks.
