Iranian Space program

Why can't Pakistan use their technology of Ghauri to put satellites in air.

Theoretically it is possible to develop a SLV from it. But practically it is very difficult.

It is on an elliptical orbit. This site shows the highest altitude at 472 km and lowest at 224 km.

It is in elliptical orbit in first phase and then it uses its intra orbital cold gas device to move into a CIRCULAR orbit..and this is exactly what keeps the sat for a year and half up there

Congrats to Iran

Well if not "For", then will it be "with"???

Awesome signature man!!

If the thruster engines work. It is experimental and the very first time, Iran is attempting an orbital maneuver.

If successful, it will help with Iran's future space missions.

Not that simple !!!

Edit: Oh, I see, the pictures are of Navid satellite. Cool.

I guess it was launched in 2012.

Good Job Iran.

No word of congrats from Saudis??

Good Job Iran.

Thanks.

No, not even one word. Neither from Turks. But it is understandable. We know their feelings though.

Hilarious! I guess you already know the answer!

Thanks.

Come on man. Don't provoke them!

Aye Aye sir. Just was answering the guy with the fact of the matter. Innocently.

One technical question for my friends here:

The mechanical energy of a satellite in an elliptical orbit is computed using this formula:

E= -GMm/2a

Where "a" is the semi-major axis of the elliptical orbit.

What I can not rationalize is the fact that the bigger "a" gets, the smaller the energy becomes. However, I think it requires a larger missile and thus more energy to put the satellite on a higher orbit. Assuming that total satellite energy equals the amount of energy used by the missile minus energy loss due to friction, then higher orbit should represent higher energy.

I'd appreciate input from anybody who knows the physics involved.

Congrats to all Irnian mates in this forum. I see Iran in the space by 2020. Hopefully the Islamic countries cooperate in the space programs since our nations contributed to the discoveries and calculating and studeing it's phenomenon.
