Iran is set to launch its 4th home made satellite into space.
It is the 2nd satellite designed by SaIran (Iran Electronics Industries [IEI]) ready for launch after successful mission of Omid (hope) satellite. Setting out a coherent plan for achieving space high tech and assuring accuracy/reliability, Iranian aerospace organizations have operationalised a comprehensive and integrated step by step approach for technology promotion and consolidation according to which upgrades are unveiled during each mission. Omid mission proved Iran's capability to successfully carry and orbit a satellite; Rasad (observer)-1 had been already shot into space showing Iran's acquisition of live satellite imaginary technologies as well as development of a gravity gradient boom. Domestic standards were finally set out for satellite design and manufacture methodologies/procedure; large number of sensors were designed and installed during Navid (promise) space mission; also, reliability of Safir 1B satellite-carrier rocket was approved given the fact that Navid payload is twice heavier than Omid.
Now, the latest Iranian satellite changes its elliptical motion into a circular orbit using nitrogen thrusters, capsules containing highly pressurized nitrogen gas at 300-400 bars; at apogee, the thrusters ignite and alter LEO into a 400km high circular orbit. Thanks to latter achievement, Fajr orbit lifetime exceeds 18 months, significantly longer than former Iranian SVs. The satellite enjoys built in-live imaginary and several new hardwares. Fajr weighs approximately 60kg. Unofficial start date of the project was May 22nd, 2009; operational prototype was delivered on 21st April, 2011 to undergo pre-launch tests. The project was finalized within less than 18 months.
Like Navid, Safir 1B will orbit Fajr; the carrier rocket has upgraded engines and more advanced fuel compared to early Safir rockets.
Iranian defense minister told that the country will launch Fajr satellite into orbit on 23rd May during a press briefing.
