"The Kavoshgar-5 rocket will be launched during the month of Mordad (July 23 to August 23) with a 285-kilogramme capsule carrying a monkey to an altitude of 120 kilometres (74 miles)," said Hamid Fazeli, head of Iran's Space Organisation.
In February, President Mahmoud Ahmadinejad unveiled a space capsule designed to carry a live monkey into space, along with four new prototypes of home-built satellites the country hopes to launch before March 2012.
At the time, Fazeli touted the launch of a large animal into space as the first step towards sending a man into space, which Tehran says is scheduled for 2020.
Iran sent small animals into space -- a rat, turtles and worms -- aboard its Kavoshgar-3 rocket in 2010.
Fazeli also announced plans for the launch in October of the Fajr reconnaissance satellite with "a life span of a year and a half, and to be placed at an altitude of 400 kilometres," the website reported.
