I was not trying to badmouth the work accomplished by the Space Agency to date, and indeed failures are a normal feature in this business. However when it comes to the weight of the satellite put into orbit by Sepah, as indicated in my previous reply, their SLV could very well have carried heavier ones considering its caracteristics. So that's not a limitation for Sepah. The aim of the launch was to demonstrate technologies and send a political message, at least as much as to launch that satellite. They demonstrated a functioning SLV, a latent road-mobile, solid fueled ICBM capability as well as carbon fiber bodied, thrust vector nozzled rocket engine with the Salman stage.Yes Sepah's first SLV attempt was a success, but looking at the big picture, the satellite they put into space weighted a measly 12-24 kg and was pretty much a small camera or webcam in space. Iran's first ever satellite, Omid from 2009 weighed 24 kgs and since then Iran has been able to successfully place 50 kg satellites into space (Fajr, Navid)
Yes the Iranian space agency has experienced some failures but you have to give them credit, they are trying to place a 350 kg payload into space. They're going forward, not backwards and the fact that they are trying to leapfrog so ambitiously to such a payload is commendable. Especially considering that Rohani slashed their budget.
Yes many of their recent launches have failed but with each successive launch, they have progressed in the various, subsequent stages. The only reason the last launch failed was because the final stage did not reach the required speed. However they did get close and previously they had issues with prior stages which they have now overcome.
Do you recall a few years ago when North Korea's missile launches were all failing one after another. At one point something like half a dozen or more failed one after another. Many in the west dismissed them and laughed. Well nobody is laughing now are they ?
Also look at how many times Space X launches have failed in the past. Recently, 4 US hypersonic tests in a row failed. Meanwhile China has already deployed hypersonic missiles on mass. Russia is close behind and North Korea keeps conducting successful tests.
The USA, the worlds sole super power, on the other hand keeps failing. How then has China been able to successfully add hypersonic weapons to its arsenal so rapidly ? The answer is simple. It's because in the last 5 years the Chinese conducted hundreds of tests while the US only conducted 5 tests.
When it comes to rocket launches, failed attempts are a part of the game. As long as knowledge is attained from each attempt and progress is made, then in the big picture the launch is actually a success.
Sepah's launching method and protocol allow for better security against potential sabotage attempts by the enemy; as a matter of fact, Trump didn't have the opportunity to parade silly satellite pictures of the IRGC-conducted SLV launch like he could do with the failed Space Agency launch.
So here the IRGC's achievement is undeniable. With regards to space launches, Sepah literally came out of the blue, surprised everyone with unsuspected capabilities and hitherto unseen technologies, succeded on their first try.
