Galaxy Roket
The Galaxy Rocket Team was founded in 2019 in Ordu by high-school students. Today it develops rocket and space technologies at Middle East Technical University (METU) with students from many departments.
Between 2019 and 2023 we built 6 rockets and launched them at the ROKETSAN Hisar Test Range; our 14,000-ft Eren rocket carried the Polaris micro atmospheric measurement and observation satellite into the sky.
In 2025 and 2026 we moved on to our own liquid-propellant systems: alongside a new mid-altitude rocket, we are developing a 100 N liquid rocket engine and a liquid-engine sounding rocket.

Rocket technology
What is inside a rocket?
Galaxy Roket is a TEKNOFEST rocket team at METU (ODTÜ) building rockets, rocket motors and avionics. We design our sounding rockets from nose cone to fins, fly them on solid rocket motors and run R&D on liquid-propellant rocket engines.
Tap a section · Positions are indicative
01 · Aerodynamics
Nose Cone
An ogive nose cone made of composite material to keep drag to a minimum. Its shape comes from flight simulations and aerodynamic analysis.
- Ogive shape
- Composite
- CFD analysis
02 · Polaris microsatellite
Payload
The payload bay for atmospheric measurement and observation. In 2023 our Eren rocket carried the Polaris Micro Atmospheric Measurement and Observation Satellite.
- Temperature · pressure
- Observation
- Separation system
03 · Dual-stage parachute
Recovery System
A drogue parachute opens at apogee and the main parachute at low altitude, so the rocket and payload land safely and can fly again.
- Drogue parachute
- Main parachute
- Redundant ejection
04 · Flight computer
Avionics
Our own flight computer runs the flight: it processes altitude, acceleration and position, fires the parachutes and streams live telemetry to the ground station.
- GPS · IMU · barometer
- 35+ km telemetry
- GSM link
05 · Propulsion
Rocket Motor
The solid rocket motor that lifts the rocket to 14,000 feet. Our propulsion unit handles motor selection, thrust tests and analysis, and R&D on liquid-propellant rocket engines.
- Solid rocket motor
- Liquid engine R&D
- Thrust testing
06 · Stability
Fins
The fins keep the rocket stable throughout the flight. Their size and position are optimised with stability margin calculations.
- Stability margin
- Composite plate
- Mechanical test

ORDOT · The 1960s
Rocketry at METU is not new, it is a tradition.
More than half a century before Galaxy Roket, a team led by Prof. Nuri Saryal at the METU Department of Mechanical Engineering worked on a guided rocket research project they called ORDOT. From the propellant to the nozzle, from the guidance electronics to the parachute head, every part was designed on campus.
The flight tests held on METU land in 1969 made the front pages. As a student team developing rockets on the same campus today, we remember this story with respect and hope to help it become better known.
77The first motor test without an explosion came at about the 77th attempt
