Omid (Persian: امید‎‎, meaning "Hope")[1] was Iran's first domestically made satellite[2][3] Omid is a data-processing satellite for research and telecommunications, Iran's state television reported that it was successfully launched on 2 February 2009.[3][4][5] After being launched by an Iranian-made carrier rocket, Safir 2, the satellite was placed into a low Earth orbit. The launch, which coincided with the 30th anniversary of the Iranian Revolution and was supervised by President Mahmoud Ahmadinejad, was also verified by NASA the following day as a success.[6][7] 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.[8] 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." [9] Foreign minister Manouchehr Mottaki said the satellite was launched to "meet the needs of the country" and is "purely for peaceful purposes".[8] Since there was very little encryption on the satellite, data could be collected and read by citizens - http://www.r00t.cz/Sats/Omid

Omid had the shape of a 40-centimeter (16 in) cube with mass of 27 kilograms (60 lb). Sources in the Iranian Space Agency say the satellite's sole payload was a store and forward telecommunication capability.[5]

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.[10][11]

Test launch

Speaking at the opening of a new space centre on February 4, 2008, President Ahmadinejad announced that Omid would be launched in "the near future".[12] On August 17, 2008, Iranian officials reported that a test of the satellite carrier was performed, and footage was broadcast of the launch of the Safir rocket in darkness.[13]

According to an American official, "The vehicle failed shortly after liftoff and in no way reached its intended position."[14] Iranian officials released a statement denouncing the allegations as propaganda and stated the Iran would soon launch the Omid satellite.[15]

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,[16] with a perigee of 246 km, an apogee of 377 km, and a period of 90.76 minutes.[17]

End of mission

Omid was reported to have successfully completed its mission without any problems. It completed more than 700 orbits over seven weeks.[18] According to U.S. Strategic Command, the Omid satellite reentered Earth's atmosphere on April 25, 2009, during an 8-hour window centered on 0342 UT. The most likely reentry location was over the south Atlantic Ocean approximately east of Buenos Aires, Argentina. No sightings were reported.[19] The rocket body from the launch, which had also entered orbit, reentered the atmosphere May 31, 2009.[20]

Further launches

Iran launched Rasad 1 on 15 June 2011 which orbited for three weeks. Other satellites have been announced as under development.
