Imagery suggests second launch attempt of Iranian satellite

Two satellite-imagery companies have released photos that suggest Iran has attempted a second launch of a satellite after the failure of the first lift-off in January.

The images released early on February 7 show a rocket at the Imam Khomeini Space Center in Iran's Semnan Province on February 5. Images from the next day show the rocket was gone and what appear to be burn marks on its launch pad.

The images were released by Colorado-based DigitalGlobe and San Francisco-based Planet.

The images showed words written in Persian in large characters including the phrase "40 years" and "Iranian made." Iran is this month celebrating the 40th anniversary of its Islamic Revolution.

It was not immediately known if the launch was successful.

David Schmerler, a senior research associate at the Middlebury Institute of International Studies, said that since Iran had made no immediate announcement surrounding the launch, it was possible it was unsuccessful.

After a launch in January failed to put a satellite into orbit, Tehran said it would launch a second satellite, called Doosti (Friendship), in the near future.
