Iran unveiled three new satellites plus a satellite booster rocket in National Space Day ceremonies attended by President Mahmoud Ahmadinejad on Wednesday.

The Simorgh light booster rocket can carry a 100-kg satellite up to 500 km above the planet.

Iran also presented the domestically-produced Tolou, Mesbah-2 and Navid telecommunication satellites.

Iran's first research satellite, Omid (Hope), designed for gathering information and testing equipment, was orbited last February and successfully completed its mission on April 25, 2009.

In 2005, Iran launched its first commercial satellite, Sina-1, into orbit from a Russian rocket.

Iran is expected to unveil five space projects during Feb 2-11 celebrations to mark the anniversary of the 1979 Islamic Revolution.
