Tehran has successfully launched a probe into space - with two turtles, a hamster and a worm on board.
Iran also plans to unveil three new satellites on Wednesday - all part its ambitious independent space programme - which coincides with celebrations of the country's 31st Islamic revolution anniversary.
The development is a great concern to the US who fears that the country's nuclear programme is at a threateningly advanced stage.
