Launch News Iran's third satellite now in orbit

[Hurricane]

Well, TecSAR is still a lot more primitive compared to the European SAR-Lupe or TerraSAR-X/TanDEM-X, but then, there we are talking about complete satellite systems already and no longer single independent satellites.

10 ton satellites are really rarely used, the last big one that I remember is EnviSAT, which is a science platform, which means: One big satellite with huge computer stuffed with all instruments and experiments that had been ready before closing the payload fairing.

And still, the record in "number of experiments per kg satellite mass" is held by the German BremSat - a very small satellite (63 kg, 48 cm diameter, 58 cm high) launched as Getaway-Special from the payload bay of the Space Shuttle on STS-60.

Well, TecSAR is rather advanced for its mass... It weighs 300kg and has a resolution of about 1m per pixel.

According to the Israelis, apparently the camera lens on the satellite is a stock 8-24 mm lens from a Sony digital camera....

Spysat? If this thing's a spysat, then the Iranians should sell them across the globe for universities around the world to spy on the sport teams of the other universities.... :rofl:

:lol: Haha that's us Israelis!
We like to underestimate our enemies... Now let's hope that it's not an underestimation on that one... :shifty:

That is just a matter of antenna size and frequency band. It uses X-Band, like the other satellites I mentioned. The power of the radar transmitter has only minimal effect from one point on. (SNR has only little effect for SAR as long as you receive reliable returns)

The bigger satellites simply have more intelligence for handling data requests and can collect bigger swipes of data as a small one can. Also you can use more sophisticated radar systems to do additional analysis of the data, for example about refraction qualities of the ground that you measure.

The German SAR-Lupe satellites get much more interesting for example when you can combine multiple satellites in different orbits on the same target. While the resolution won't increase much there (official is 0.5m, theoretically it should go past 0.1 m), you get much better contrast and less multi-path effects blurring the images (Giving you a true 0.5m resolution instead of a 1 m pixel)

They started with German Engineering. They should better have kept using it instead of thinking they can do it better themselves with the Vanguard. :lol:

We built the Vanguard for comedic purposes, obviously. :lol:

Yeah, and Hollywood is proud of you. Luckily you did Vanguard before Michael Bay could try it. :lol:

To me any development of Iran's capability to put payloads into orbit ( east or West bound) scares the sh.. out of me in lue of their nuclear development program (and ambitions)
Am I just blind or can I see the writing on the wall here ..........:shrug:.

Best to shut them down while we still can...........

Nope, you're not the only one seeing it. It is indeed scary that they can deploy satellites, and yes, we need to shut them down. Perhaps, on other, more peaceful days, this wouldn't have been so alarming... :shifty:

 

[Urwumpe]

Maybe you are blind and see a writing on the wall that isn't there.

The rule of thumb is: Throw weight over 5000 NM is eight times the mass that a rocket can put into orbit.

This ignored a lot of other factors, but is generally working good enough for estimating how far the technological capability of a country is to build ICBMs.

A satellite launcher is only a poor ICBM. And the other way around.

If you go by that kind of argumentation that all spaceflight is military technology, I would be much more afraid of Russia or China. Or India. Iran is just the pawn in the thermonuclear war game.

But just look at the facts. The German V-2 rockets scared the hell out of the British citizens, no matter how primitive they are. And after the war ended, the USA and the Soviet Union took the very German scientists that built V-2's and made their own rockets. And look where we are now. :facts:
What I'm saying is, that they can grow up pretty fast, and if we don't put our eye on them, we WILL suffer from the outcome.
I know, China and Russia are scarier right now, but they don't threat half the world to be "wiped off the map".

If Germans wouldn't have invented it, somebody else would.

ahem...your world. I know world is a very personal thing. :lol:

But yes, you are right, Iran should stop using the same language as all Arab countries when it is about Israel. But wouldn't it be better to make all Arabian trolls simply get the stupid minority in a future world in which Arabians maybe simply have no problem with Israel and maybe even like it and would dream of studying aerospace engineering in Jerusalem, instead of studying it in Tehran combined with the lectures about how Al-Kuds was stolen?

I know, my point is that the Irani people can get far from that awful beginning.

Indeed. But they do threaten America too every now and then.
And no, you can't tell a billion people that believe in something that it's a lie.
They think that Israel is promised to them, we have some old news: we were here before them. They are part of us.
Forget it, they won't get it in the near vicinity.

 

[Urwumpe]

They think that Israel is promised to them, we have some old news: we were here before them. They are part of us.

And some have been there before your ancestors came. And between you and your ancestors, there had been others who cared for the soil that you now live on.

It is pretty futile. What counts is today.

No need to sweat this much. Even if Iran (hypothetically) builds a couple of ICBM's able to reach the USA ground (mind you, for them it's much harder than for the USSR in 1957, because the distance is just greater by few thousands km), you will still have over 2500 nukes (and more "delicate" means) to shut them down at any moment.

Come on, is it so easy to scare the sh. out of you?

10 ton satellites are really rarely used

Indeed. The rarity of use of even the heavy-lift (~25 ton) class makes the military uses dreamt up by HLV advocates as a catalyst for high flight rates even more absurd-sounding.

...ok, that was totally off-topic. :lol:

A second launch on Saturday!?

Well are the Iranians trying to do a double shot? Some sources are reporting that a second satellite could be launched on Saturday! :blink:

With such a high flight rate and reliability , the Iranians should set up a commercial cubesat launch service for the Islamic world to further increase their launch rate. Now THAT would be a blow to the Western world's sanction effort! :rofl:

 

[Cosmic Penguin]

Oh and this rocket do carry a rocketcam after all...

 

[mahdavi3d]

Some sources are reporting that a second satellite could be launched on Saturday!

as sources in iran, next launch will occur SOON (not exactly this Saturday, maybe in this Months or Later...)

Iran Navid Satellite Pre-launch & Assembly

this video was uploaded by reza2740 {military.ir} originally and for the first time. thanks to him.

Head of the Defense Ministry's Aerospace Industries Organization, General Seyyed Mehdi Farahi, in this video:a fully new rocket fuel has been created by iran and 'navid launch' was a satellite launch and fuel test, both together.

3. safir-navid --> safir-1b (upgraded new engine + new fuel)
2. safir-rasad --> safir-1a
1. safir-omid --> safir-1a

Navid Satellite First Image of Strait of Hormuz
The First image of Navid Satellite of the Strait of Hormuz was received and transmitted, FNA reported a few hours ago.
Hossein Bolandi , , reported that today at 4:33 PM, we could take the first real time image of the Strait of Hormuz by Navid Satellite in the worst weather condition.
Bolandi added that this is the first time in Iran’s space history that we have been able to take this image.

picture bellow, shows one of satellite passes where the first image is taken (thanks to reza4087 {military.ir})

"navid" images resolution is 400 meters. seems not good. but no problem, because "navid" is just a beginning and as like as a short quiz for "Elm-o Sanat" University abilities. "Elm-o Sanat" main satellite, named "zafar" will be ready for the next year. a really professional and high performance satellite.

and what about next year (Iranian new year begin on March 20)

{...}
Iran’s Defense Minister Ahmad Vahidi says the Islamic Republic is establishing a new satellite launch base to put super-heavy satellites into orbit.

Vahidi said Thursday that the base will be used to launch one-ton satellites into an orbit of 1,000 kilometers.

He said that among Iran’s next year plans was the launch of Tolou (Rise) and Fajr (Dawn) satellites into orbit.

Vahidi also said that Iran is planning to launch satellites into orbits of up to 36,000 kilometers next year.

Vahidi also said that Iran is planning to launch satellites into orbits of up to 36,000 kilometers next year.

Seems very unlikely, because Iran's rocket technology isn't mature enough to produce medium-to-heavy lift launchers and booster stages capable of autonomous operations in space. Unless they want to put a very small payload to a highly elliptical orbit. That's about pointless, but may be a realistic option.

 

[Loru]

Aeroshell / fairing looks very crudely manufactured. Like unfinished glass fiber boat structure.

 

[T.Neo]

Is it just me or does the whole thing seem... 'shabby'? That probably isn't the best way to describe it, but its manufacturing and surroundings don't look as... shiny and high-tech as those in say, the US.
