The Iranian satellite Fajr or ‘Dawn’ was launched on February 2, 2015 at 0850 UT from the Imam Khomeini Space Center which is south of Semnan in the northern part of the Dasht-e-Kavir desert.

The 52 kg satellite was carried on a Safir launcher into an initial orbit of 223 km by 470 km with an inclination of 55.5° and has been given an object ID of 2015-006A 40387. It is Iran’s fourth satellite and its first successful orbital launch since Feb 2012. Fajr has propulsion in the form of a cold gas thruster which can be used to circularize the orbit at around 470 km which may give it a lifetime of over a year.
