A capsule, codenamed Pishgam (Pioneer), that was sent into space containing a live monkey in January is displayed during a rally in Tehran's Azadi Square (Freedom Square) to mark the 34th anniversary of the Islamic revolution on February 10, 2013. Hundreds of thousands of people marched in Tehran and other cities chanting "Death to America" and "Death to Israel" as Iran celebrated the anniversary of the ousting of the US-backed shah.
