Iran has launched a rocket that is designed to carry living creatures into space.
Iran's official IRNA news agency reported Thursday that the Kavoshgar-4 rocket was test launched on Tuesday. The rocket is intended to carry monkeys into space in future launches.
IRNA said the space agency aimed to test the performance of the launch pad, the engine and the electronic systems.
Iran tested a previous version of the rocket in February of last year. The White House called that test a "provocative act."
Tehran's ambitious space program has worried Western countries, which fear the same technology used to launch satellites could be used to launch nuclear warheads.
