Build. Sail. Fly.

Glex is your launchpad to explore rockets, boats, and drones in one futuristic web experience.

Rockets

Discover engines, launch stages, orbit goals, and real mission profiles.

Explore hull designs, propulsion systems, navigation basics, and sea safety.

Learn about flight control, camera payloads, range optimization, and legal flight zones.

The Saturn V rocket, used for the Apollo missions, is still the most powerful rocket ever launched and produced 7.6 million pounds of thrust at liftoff.
Rocket fuel can reach temperatures above 3,300 C (6,000 F), hotter than the surface of the Sun.
The first liquid-fuelled rocket was launched by Robert Goddard in 1926. It only flew for 2.5 seconds and reached 12 metres high.
SpaceX's Falcon 9 booster can land itself back on a drone ship at sea, allowing it to be reused many times.
Rockets do not push against air, they work in the vacuum of space by ejecting gas in one direction and moving in the opposite direction.
The sound of a rocket launch is so loud that NASA sprays large water volumes on launchpads to absorb sound energy.

The world's largest container ships are around 400 metres long, longer than four football pitches end to end.
Wooden boats have been used for over 10,000 years.
A ship floating in saltwater sits slightly higher than in freshwater because saltwater is denser.
The fastest boat ever recorded was Spirit of Australia in 1978, reaching 511 km/h.
Icebreaker ships have rounded hulls so they can ride up and crack ice with their weight.
The Titanic's anchor chain links were each roughly the weight of a small car.

NASA's Ingenuity helicopter on Mars was the first powered aircraft to fly on another planet.
Some high-performance consumer drones can exceed 290 km/h.
Drones are used for tree planting in reforestation projects.
A drone's propellers often spin around 8,000 to 10,000 RPM.
Long-endurance drones can fly for more than 30 hours continuously.
Package delivery drones are already used commercially in selected regions.
