Satellite photos show burning Iran space center launch pad

A rocket at an Iranian space center that was to conduct a satellite launch criticised by the US apparently exploded on its launch pad Thursday, satellite images show, suggesting the Islamic Republic suffered its third failed launch this year alone.

State media and officials did not immediately acknowledge the incident at the Imam Khomeini Space Center in Iran's Semnan province.

However, satellite images by Planet Labs Inc. showed a black plume of smoke rising above a launch pad there, with what appeared to be the charred remains of a rocket and its launch stand.

In previous days, satellite images had shown officials there repainted the launch pad blue.

On Thursday morning, half of that paint apparently had been burned away.

"Whatever happened there, it blew up and you're looking at the smoldering remains of what used to be there," said David Schmerler, a senior research associate at the Middlebury Institute of International Studies.

Schmerler told The Associated Press that the images of the space center suggested that the rocket either exploded during ignition or possibly briefly lifted off before crashing back down on the pad.

NPR first reported on the satellite images of the apparent failed launch at the space center, some 240 kilometers (150 miles) southeast of Iran's capital, Tehran.

Iranian satellite launches had been anticipated before the end of the year.

In July, Iran's Information and Communications Technology Minister Mohammad Javad Azari Jahromi told The Associated Press that Tehran planned three more launches this year, two for satellites that do remote-sensing work and another that handles communications.

The Nahid-1 is reportedly the telecommunication satellite, which authorities plan to have in orbit for two-and-a-half months. Nahid in Farsi means "Venus."
