Unlike the Gokturk SLV - this one is liquid propelled:

Any info on propellants? Fuel:oxidiser volume ratio based on crude measurement of diagram is about 1:1.65. So definitely not hydrogen or light hydrocarbon, guess kerolox?

Tal Inbar says on twitter that no extra info was provided other than what's in the poster. I've had a look at Roketsan's site, and it doesn't look like there's anything there either.

That's the volumetric relationship of a gas generator kerosene lox engine (~2.3 O/F).

Thought so, makes sense.

 Here's the original release (via google translate) from the SSB, unfortunately no timeframe is mentioned. They do have an image which afaik is new.

SSB and Roketsan signed a contract for Micro Satellite Launch System (MUFS) Development Project. When the project is over, micro-satellites of 100 kilograms and below will be placed in the low-earth orbit with a height of at least 400 kilometers. Turkey, owned by the country of the world satellite launch, testing, will have gained the ability to produce infrastructure and bases.

The project covers the development and testing of the Micro Satellite Launch System, which can accommodate micro-satellites of 100 kilograms and below, with a height of at least 400 kilometers in the Low Earth Trajectory. Under the contract, Roketsan will develop the Micro Satellite Launch Vehicle and install the test / production facilities and launch base. Thus, Turkey has few countries in the world where satellite launch, testing, will have gained the ability to produce infrastructure and bases.

Where is Turkey going to launch from and in what direction? The country's location is not exactly favourable.

The Space Technologies Research Institute of Turkey (TÜBİTAK–UZAY) and the Directorate General of Civil Aviation, a public body that regulates civil aerospace, will both see 20% of their budgets redirected to the agency. On the basis of their official 2019 budgets, this amount alone will add up to almost 30 million Turkish Liras (US$5.7 million).
The new agency will coordinate these agencies, as well as Turkish Aerospace Industries; Roketsan, a major Turkish rocket producer; and TÜRKSAT — a semi-private satellite organization, the order says.

We hope they show in the next months, the new website and logo of this space agency...and more details, about her launcher...

And they increase the Science budget, 400 million of $ is not to much, and the space agency will have only a fraction of this...

Answer for a very old question. (Learned this topic exist now)

For sounding rocket tests, Turkey using rocket test center in Sinop (A Black Sea City)

For orbital launches there are discussions continues about 3 options

Option 1: A small launch center at the shores of the Black Sea, Close to the Bulgaria. This option is not good for additional orbital velocity and possible Inclinations but Black Sea helps for a clear launch path.

Option 2: A launch site at the East side of the Africa. This option discussed with some countries. (Possibly Somalia)

Option 3: A sea launch system operates in Mediterranean Sea. A couple weeks ago Russia offered to operate a joint sea launch center to Turkey.

The joint Russian Sea launch option sounds like the best. Benefits both countries too.

Micro Satellite Launch System (MUFS) is far in the future - first launch currently planned for 2026. They are now developing a technology test vehicle called "Sonda", launch NET 2023.

Quote
The Sonde Rocket, which is targeted to be launched in 2023, will be a technology platform where MUFA technologies will be tested, with the ability to lift at least 100 kilograms of payload above an altitude of 300 kilometers.

https://www.defenceturk.net/mikro-uydu-firlatma-sistemi-mufs

This sounds like Sonde will go orbital, but I wonder if that is a misundestanding. MUFS is designed for 100 kg to 400 km. Why would they take three more years to add that 100 km from 300? Maybe just a suborbital demonstrator.

 I think 'Sonda Roketi' might just be intended as 'sounding rocket'.

You are correct. "Sonda roketi" is the Turkish translation of the sounding rocket.

Turkish Space Ageny released their maiden flight prediction for the indigenous SLV.

Şimşek (Lightning) 1: 550 km circular orbit (42.5-45 degree inc) - launch prediction:2027

Şimşek 2 : 700 km SSO - launch prediction: 2029-30

Şimşek 3: MEO-GEO - launch prediction: 2036

They're saying that they'll launch their SLVs from a new space center that is being built in İğneada. Not sure if they're clear with used up stages falling on Eastern Turkey/Levant for low inclination missions or on Egypt on SSO, but we'll see.

Seems like Turkish SLV development is divided up to 4 stages.

First is development of underlying technologies with sounding rockets. This was up to the most recent SR-0.1 model.

Up next is what I think is a proof-of-concept stage with SR-1.0 sounding rocket. SR-1.0 could be a direct implementation of designs they will use for their MUFS(seems like its an acronym for Micro Satellite Launch System in Turkish) SLV. According to what Roketsan wrote in their homepage :

Quote
Once the MSLV project currently underway at the Satellite Launch Space Systems and Advanced Technologies Research Center of Roketsan is complete, scheduled for 2026, it will be possible to place microsatellites weighing 100 kilograms and below in a Low Earth Orbit at an altitude of at least 400 kilometres. Turkey will thus gain possession of launch, testing and manufacturing capabilities, and the ability to establish a spaceport, placing it among only a few countries in the world with the necessary knowledge and infrastructure.

So when they are done with SR-1.0, MUFS is next to follow. It will probably leverage most of the SR-1.0 and scale it up for the 1st stage and 2nd stage. According to information I've found, third stage seems to be liquid fueled. I think it is a pressure fed engine up there. SR-1.0 will be launched on autumn this year according to Turkish sources.

Then there's another rocket called Şimşek, a liquid-fueled rocket series. I'm not sure if it is a incremental program that follows after MUFS or concurent. I personally think that they are concurrent programs, considering that the scheduled launch dates are only a year apart and they use different fuels.

Whatever it really is, I'd say it's a pretty darn ambitious plan, to put it lightly. I've thought that these kind of schedules are trademark for your average new space start-ups whose launch schedules postponed every year. Of course Roketsan, which seems to build missiles for the Turkish army including ballistic missile, would be better off than most of those start-ups in terms of meeting their goal, though I'm still dubious about their plan to launch Şimşek by 2027.

From the looks of it, both the first and second stage are powered by turbopump fed engines, most probably a GG cycle. If they were to develop an engine for a future SLV that will fly by 2027, there should have been a lot of progress regarding the turbopump development by now. I can't find any of it. In case they are getting them Yuzhmash, which seems very possible, it's still weird there ain't any information regarding the engine prototypes.

Anyways, their plan regarding liquid fuel rocket development and the lack of information regarding the engine is surely very weird. I'll stay dubious about the Şimşek until they show at least something about their engine, but MUFS seems plausible enough, albeit with very real possibilities of delays.

Turkey tested a new sounding rocket SR-1.0 made by Roketsan.

In this test, target altitude is 300 km with 100 kg payload.

Does this mean that the apogee of this launch was 300 km?

According to the officials that was the apogee of the suborbital flight.
