President Mahmoud Ahmadinejad supervised the launch, which coincided with the 30th anniversary of the Iranian Revolution; NASA verified the launch's success the following day.{{cite web |url = https://nssdc.gsfc.nasa.gov/nmc/spacecraft/display.action?id=2009-004A|title=NASA NSSDC Master Catalog |publisher=NASA NSSDC |date=1 June 2009}}{{Cite news|url=https://www.theguardian.com/world/video/2009/feb/03/iran-satellite-launch|title=Video: Iran sends first homemade satellite into orbit|newspaper=The Guardian|date=February 3, 2009|via=www.theguardian.com}} Its Satellite Catalog Number or USSPACECOM object number is 33506.

Ahmadinejad said the satellite was launched to spread "monotheism, peace and justice" in the world.{{cite web | url = http://news.bbc.co.uk/1/hi/world/middle_east/7866357.stm | title = Iran launches homegrown satellite |date=2009-02-03 |access-date=2009-02-04 | work=BBC News}} The Tehran Times reported that "Iran has said it wants to put its own satellites into orbit to monitor natural disasters in the earthquake-prone nation and improve its telecommunications."{{cite web | url = http://www.tehrantimes.com/index_View.asp?code=188488 | title = Iran's Omid satellite launched into orbit|date=2009-02-04|access-date=2009-02-15}} Foreign minister Manouchehr Mottaki said that Iran launched the satellite to "meet the needs of the country" and that it was "purely for peaceful purposes". Since there was very little encryption on the satellite, data could be collected and read by citizens.{{Cite web|url=http://www.r00t.cz/Sats/Omid|title=r00t.cz : Sats / Omid : browse|website=www.r00t.cz}}

Omid had the shape of a {{convert|40|cm|adj=on|sp=us}} cube with mass of {{convert|27|kg|sp=us}}. Sources in the Iranian Space Agency say the satellite's sole payload was a store and forward telecommunication capability.

The launch of Omid makes Iran the ninth country to develop an indigenous satellite launch capability.

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.{{cite news|url=https://www.usatoday.com/news/world/2008-02-17-iran-space_N.htm|newspaper=USA Today|title=Iran space rocket successfully transmits data|date=2008-02-17|access-date=2009-02-04}}{{cite news|url=http://news.bbc.co.uk/2/hi/middle_east/4381436.stm|title=First Iranian satellite launched|date= 27 October 2005|publisher=BBC|access-date=2008-08-17}}

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".{{cite web | url = http://www.debka.com/headline.php?hid=5000 | title = DEBKAfile - Iran launches first space research rocket Safir 1 | access-date = 2008-02-04 | archive-date = 2009-09-03 | archive-url = https://web.archive.org/web/20090903225225/http://www.debka.com/headline.php?hid=5000 | url-status = dead }} 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.{{cite news|title=Iran launches satellite carrier |url=http://news.bbc.co.uk/1/hi/in_depth/7566804.stm|work=BBC News|access-date=2008-08-17 | date=2008-08-17}}

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,{{Cite news | title = Iran puts satellite into Earth orbit | author = Stephen Clark | url = http://spaceflightnow.com/news/n0902/03iran/ | magazine = Spaceflight Now | date = 3 February 2009 }}

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.{{Cite web|url=https://www.spaceweather.com/archive.php?view=1&day=26&month=04&year=2009|title=Spaceweather.com Time Machine|website=www.spaceweather.com}} The rocket body from the launch, which had also entered orbit, re-entered the atmosphere 31 May 2009.{{cite web |url=http://nssdc.gsfc.nasa.gov/spacewarn/spx667.html |title=SPACEWARN Bulletin 667 |publisher=NASA NSSDC |date=1 June 2009}}
