Iranian Space program | News and Discussions

[Hack-Hook]

Two things at least need to happen for an effective space program:

- reusable, reusable, reusable….
- at least one launch a month to carry at least one ton of payload and various orbits

Goal: indigenous GPS, networking, military
Time: by 2035.

reusable is nice but its not a must , Russia don't have it only usa have it and China is working on it but are they the only effective space program
to me finding a partner to shell some of the costs and solve some technological barriers is more important, several candidate that come in mind are turkey, Pakistan, and some of Persian gulf countries now that our relation with them is improving

I disagree. Can't find partners when lift is expensive. Reuse drops costs significantly. Space lift will become standard hauling soon and providers with expensive hauls will be left in the dust.

depend on how expensive the launcher will be
what is the price tag for Sarir or Soroush launch?
now what will be the price for a reusable version , falcon 9 full thrust 65-70 million per mission its 22.8t to LEO . now answer me when we reach that capability?

i wonder if Zoljanah is a genuine SLV or its test bed for Soroush boosters
its first or second stage can do the job nicely

Soroush is supposed to be liquid fuel and not planned until 2030+, so I don't think so. I think it is standalone option

Zoljanah has same solid fuel first and second stage as far as I know. it's a very powerful engine actually. doesn't have TVC but in terms of thrust it is even more powerful than Raafe

so Zoljanah total thrust > Qaem-105 total thrust (assuming Qaem-105 uses second stage Raafe)

indeed.

I remember commenting a year or so ago that the space programme was close to critical mass and achieving a lot of success. slowly slowly then all at once.

Simorgh was only ever one launch away from success

Zoljanah is close to first orbital launch

and Qaem series follows a modular and reliable approach


that is Russian imaging technology and Khayyam is 300kg satellite, so not any time soon

but Iran has projects for 2m resolution and 1m resolution, should be reached later this decade

Thank you

Piet

Soroush have several booster attached to it . those are usually solid fuel

Bahman cryogenic engine not ready until 2030-2032

ISA is not planning that far ahead ... they made Zoljanah after 4 failures of Simorgh. now they fixed Simorgh maybe they don't care too much about Zoljanah (even though it is superior to Simorgh is almost every metric)

problem with solid fuel is its a dead end , you can make them bigger to an extent after that its very hard , unless they master making a cluster of them , making liquid fuel engines more powerful is a lot easier and cheaper

for civilian space program liquid is better because you can stop and start the engine for more precision and control

but if you just want something reliable for LEO nothing wrong with solid fuel

I am still waiting for SLV with cluster of 4 Khorramshahr engines as first stage

zoljinah can be useful for sending something to Leo or perhaps something very light to MEO on short notice, but let be honest its limit is 200kg maybe 300kg .
but what if we want to replace khayyam with something of our design in 4 years (its life time is just 5 year) for that our only option is liquid fuel sarir


for 4 Khorramshahr engine clustered i think we must wait for sarir with its wider body to be able to put those engine there

Khayyam series has 3 more satellites to go, the next 3 to be co-built in Iran I think. so we are fine on that front for next 15-20 years

I thought purpose of Zoljanah was 10 x 20kg microsats at once, that's what they talk about a lot

I wonder how many satellites needed for IRGC GNSS project and how big they have to be and what orbit they must reach? that is the IRGC's focus now

the lower the altitude the more sat you need
10x 20kg sat , i dont think its possible on zoljanah , you need to package those sat you need an ejection system all those take space and have some mass. the slv at its current form only rated for 250kg to leo at 55 degree for at 98 degree its 100kg
my guess is the best it can manage is 2-3 maybe 4 but that is a little doubtful

they talked about using Zoljanah for 10 satellites at once, maybe they will weigh less than 20kg each

according to chat GPT a LEO GNSS network needs 80 satellites

25-30 satellites for a higher orbit (MEO) like GPS and GLONASS and Galleo

maybe i don't knew how much they weight but one thing is clear Zoljanah can be used to replace those satellite very fast , they even can have several zoljanah loaded and ready to launch at our missile cities, so in case of something happen to those satellite they be able to replace them in matter of hours instead of weeks.

also there is another use for zoljanah , Iran want a threshold Nuclear status , we reached it in Enrichment front , for others zoljanah can be reminder that we can reach Japan to England a more powerful version or one with lighter Delivery package probably can reach Australia to new York or Guam consider it like Minuteman missile and Minotaur Rocket but in reverse role
