It may be appropriate to launch the satellite from which region of Turkey:
1- From the shadow of the Black Sea in the Thrace Region
2- From mugla to mediterranean (for example towards libya)
3- sinop (more suitable for probe rockets)
4- From the launch center of a foreign country (e.g. Baikonur Alcântara)
5- From mobile sea launch pad View attachment 1475
Good suggestions. I suppose Sinop is the best location since it allows for both eastbound and westbound launches PLUS northbound launches for polar orbits. In all cases, the first stage can safely fall down into the Black Sea.

As a wildcard, a remote launchpad in Somali may be considered later on because of open access to the Indian Ocean and its advantageous location close to the equator, which saves a lot of fuel. (It is the reason France launches their rockets from the French Guiana near Brazil.)

None of the above.

One choice: form Datça; first stage falls into the Mediterranean Sea, second stage in to the Indian Ocean.
Second choice a launch ship launches from the sea. either in the Mediterranean Sea or the Indian Ocean.
Third choice: Launch from Somalia, a ship takes all the components to location and launches from Somalia shores.

I believe the priorities for launch location selection would be.

1 - Where the disposed parts will fall: first, second and possibly third stages have to fall onto uninhabited or scarcely inhabited terrain.
2 - Proximity to the equator for easier acceleration of rocket due to the assistance afforded by the rotation of the earth.
3 - Easy access to location by sea, road, railroad
4 - Security of location
5 - Friendly climate; ample launch windows

If the first stage provides enough thrust, the second stage doesn't have to fall back into the sea. It can either burn in the atmosphere at re-entry or remain in orbit and become part of the thousands of pieces of space junk.

I wouldn't tell this to anyone.

We don't know if the second stage does always fall dawn or stay in orbit. I heard it falls.

Best choice would be to make them recoverable/reusable like Space X does. But please note that Space X is the only company that so far could pull this stunt off. So getting there is a long voyage. We should start with smaller steps and gradually get there. It would be best if we could leapfrog many steps of progress but alas, with what background will we do that.

We don't have to make recoverable rockets. Like you said there's only one company (SpaceX) using such rockets. Everybody else, literally ALL space-faring nations, leave space junk in orbit and there's no reason for Turkey to become an exception at this point.

I feel like there will be a serious cooperation and technology transfer with Ukraine regarding large solid and liquid rocket engines and subsystems.

The possible locations where the disposed parts will fall is the major determining factor. Probably a test flight will show where they will land before a permanent launch site can be established.

Black Sea!
Launching from Sinop allows for safe first-stage splashdown in all directions except south. The only reason to follow a southward trajectory would be to achieve a polar orbit which can be attained with a northbound launch as well, making Sinop VERY ideal.

I don't know which way you exactly need to shoot to get to orbit but from what I know it is better to shoot closer to the equator along with the other criteria of watching where your litter will fall. From this knowledge a Datça launch seems to be a more favorable option than a Sinop launch provided that the dropped stage will splash the sea in both cases. The Datça option was once voiced by the head of Tübitak back when the issue was first raised. I am fully in favor of a shipborne launch though as it will give a big flexibility as to where you can launch from.

In which direction you want to launch your rocket depends on the final orbit you want to achieve. For almost all orbits (except polar and a few others) it is best to launch from a spot close to the equator because the rotation of the Earth at the equator is the fastest and adds momentum to the ∆v of the rocket, thereby saving fuel. Of course, that doesn't mean you HAVE TO do that. Russians, for example, launch almost all their rockets from Kazakhstan, far from the equator, but that comes at an added cost as their rockets must therefore carry more fuel and be heavier, which is a disadvantage. Equatorial launch is best suited for geosynchronous orbits (telecom satellites) as such orbits line up with the Earth's equator at about 35000 km altitude.

The reason Sinop is ideal is because:
  • Ability to launch west, northwest, north, northeast, east and southeast directions and splashdown the first stage in the Black Sea. This allows Turkey to, for instance, utilize highly elliptical Molniya-type orbits for applications like regional GPS or polar orbits for spy/recon satellites. If you launch for polar orbit from Datca the first stage would fall down somewhere near Izmir/Manisa. If you launch south from there the rocket will have to fly through Greek airspace.
  • Safety -- Black Sea is less prone to attack by Turkey's traditional enemies than a spot along the Mediterranean or Aegean Sea. Datca is extremely exposed. It's very close to Greek islands Kos, Rhodos and others.
  • Existing Infrastructure -- Sinop missile test range is already a military zone and has infrastructure in place (supply depots, hangars, C&C systems, radars, etc.) whereas Datca is a tourist town.

If you move to east of Marmaris instead of Datça there is unobstructed airspace and the second stage falls in the Indian ocean. I don't know where the second stage falls when you launch into Blacksea. The second stage has been mentioned to fall. I am unaware of the second stage being left in space. It will depend on the technology used on the rocket I guess. Somebody should ask these questions to the TUA Chief when they get hold of him. He should clear up the situation If they already figured out what to do.

We don't have to splashdown the 2nd stage at all, we can leave it in orbit. Especially if we use strap-on boosters along with the first stage to give our rocket a high ∆v from the get go. There are many examples of this, See: https://en.wikipedia.org/wiki/Two-stage-to-orbit

GUHEM space and aviation training center was opened. GÖKMEN will be trained here. In Turkey, the astronauts gave GÖKMEN name.
