Dude, the point is higher orbit actually represent less energy.you simply missed the - at that formula.my words might be worng though.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.

But the formula doesn't show this.The higher the orbit, the higher is total energy of the satellite (potential energy + kinetic energy). That is why bigger rockets (imparting more energy) are needed to achieve higher orbits.
Along with this image, there is another image, which is Iconic (for us).The important thing is not to abandon the program. India during the early days of its space program could not even afford proper satellite transportation and used bullcart to transport its satellites to launch pad:
But the program was never abandoned and eventually produced this:
It should be a lesson for Iran. Never abandon the science projects.
Congratulations Iranians!
Wish you success in further space technologies and launches!

"-" is a sign that the potential energy of the satellite is more than its kinetic at any given orbit. However, the formula suggests that the bigger the apogee, the lower the total energy. This is what I don't understand.

We enjoy it anyway. Glad to see Indian's progress.@ Indians......this thread is not about Indian space program.....
Good Job Iran.
No word of congrats from Saudis??
Turkey is well in the right path in science and tech. Be fair. Exclude Turkey from this.Thanks.
No, not even one word. Neither from Turks. But it is understandable. We know their feelings though.

Turkey is a well advanced country in most practical fields of science and tech. They lag in one section but well ahead in other ones.
Actually, in whole Islamic world and Middle East, there are only few countries on the right path. Countries like Turkey, Iran, Malaysia, Indonesia, Israel and to some extent Pakistan and Kazakhstan. This is why I give credit to Turkey and even Israel while I,m Iranian. I consider them very successful. We should learn from them in some points and they should learn some from ours.
Keep going Islamic nations
wow... this is some serious sh...it... I like it... you can fit a whole house in its nose!! India is well ahead of Iran in space tech... I wish Iran can catch up soon... Long live India
