Small clarification from my previous assessment.


From a new Iranian article posted on 7th June 2020, the third stage is presented as the solid-propellant Arash-24, with a purported mass of ~100 kg. The mass of the Salman-1 second stage being about ~300 kg.

And from the Mission Control screen, we know that following the second stage's ignition at T=150 seconds, a third burn was performed at T=420 seconds.

This means that currently there are only the Arash-24 solid propellant third stage and the Noor-1 satellite orbiting the Earth.

The Salman-1 solid propellant second stage reaching only a velocity of 5'250 m/s at cut-off, after 70 seconds of burn, and a 403 km altitude, simply re-entered the atmosphere, unable to reach orbital velocity.

This orbital insertion velocity of ~7'650 m/s was achieved with the third stage Arash-24, reaching an apogee of ~444 km.

Thereafter, the Noor satellite used its own six cold gas thrusters to separate from the third stage and manoeuvre in orbit, orienting its camera toward the earth's surface.

Meanwhile the same article announced the launch of Noor-2 satellite this month (June 2020).

No time was given,..they just said its ready to be delivered and will have to be placed in 36000km orbit.
With this current administration we cannot expect things to be done properly in the space sector, lets see how the next administration handles the space program. We should have had dozens if not a hundred satellites into orbit by now.

Iran to Build Nahid 3 Satellite for Geo Orbit

TEHRAN (FNA)- Deputy Head of Iran's Space Research Center Jafar Salehi said that the country plans to manufacture Nahid 3 (Venus 3) satellite to be placed into the geostationary orbit.
“Nahid 3 is the final step in the telecommunication satellites which will be built to pave the ground for Iran’s access to geo operational orbit,” Salehi told FNA on Sunday.
He added that the satellite is now in the study, feasibility and conceptual design phase.

Salehi also said that at present Iran has designed and built the engineering sample of Nahid 2 telecommunication satellite and has delivered it to the Iranian Space Agency, adding, “We are preparing for delivering the qualitative sample of the satellite.”

Earlier this month, Salehi had said that Iran would send a new telecommunication satellite named Nahid 1 (Venus 1) into the orbit.

“We have had the construction of Nahid 1 and Nahid 2 satellites on our agenda. Nahid 1 was completed 3 years ago and its periodical tests have been conducted and it can be launched and Iran plans to orbit it,” Salehi said.

He added that Nahid 2 which is more advanced than Nahid 1 is also under construction, explaining that it enjoys the capability to go to higher orbits.

Salehi said that Iran will soon start designing Nahid 3 satellite.
