First mock of 5 gen fighter.
Then mock up of an aircraft carrier.
Now mock up of spacecraft.
Cardboard companies in Iran are doing good money.
Rodong-1 began tests in 1993 and was deployed in 1997.Rodong (or Nodong) as far as I know is a single stage rocket. Safir has two stages. The difficulty is passing the threshold of single stage into multiple stage.
Rodong-2 - Wikipedia, the free encyclopedia
Iran used scuds during the war with Iraq so they may have used that as a base to start the development.
And recently the experts believe that it is Iran helping North Korea not the other way around:
What North Korea's Rocket Launch Tells Us About Iran's Role : NPR
Dont u think is ridiculous to a make mockup of manned capsule when u cant launch even a tiny micro satellite to stable orbit?
In order to launch man to space u need a launcher 10 times more powerful than Simorg, which u still dont have.
Overall man in space is extremely expensive thing with little practical value. Thats why Europeans and Japanese who are light years ahead of Iran and 10 times richer dont even bother.
In order to launch m to 100 km altitude u need to spend m*10*100*10^3 J = m*10^6 J of energySafir's first stage will be enough for suborbital launch ...
You think !?
Rodong-1 began tests in 1993 and was deployed in 1997.
Shahab-3, which is virtually exact Rodong-1 copy, began tests in 1998 and was deployed in 2003.
Safir uses Rodong-1 as first stage and third stage of Unha as second stage.
Simorgh is two stage version of Unha instead of 3. So its basically a downgraded Unha.
In order to launch m to 100 km altitude u need to spend m*10*100*10^3 J = m*10^6 J of energy
In order to accelerate m to 8 km/s u need to spend m*16*10^6/2=m*8*10^6 J
Thus orbital launch to 200 km needs 10 times more energy.
They launched a toaster. To launch human they need 20 times more powerful rocket.They have just launched a satellite to a higher orbit than 200 kms!

solid fuel launcher and ********** thrustersAre those the thrusters?
حداقل ۵ ماهواره ساخته شده داریم که مدتها است در نوبت پرتاب قرار دارند و اینها اجازه پرواز پیدا نکردند! بنابراین احساس ميشود دولت ملاحظاتی دارد تا مذاکرات سیاسی آسیب نبیند در حالی که پرتاب ماهواره دست مذاکره کنندگان را پر ميکند. بنابراین با وجود آماده بودن ماهوارهها، پرتابی صورت نگرفته. ماهوارههای پیشرفته که در مدارهای بالاتری قرار ميگیرند و طول عمر ۲ تا چند ساله داره دانشگاه شریف ماهوارهاش را مدتها است تحویل داده.
WTF, 5 launches have been halted by this f@cking government.
ماهواره امید از صفر تا صد، از صد تا صفر
