A lone tree stands beneath the brilliant Cygnus region in the night sky over Guadalajara, Spain. This deep-sky image combines multiple exposures to reveal glowing clouds of hydrogen gas, dark lanes of interstellar dust, and vast regions where new stars are forming. Home to famous objects such as the Veil Nebula, Crescent Nebula, Pelican Nebula, and Cygnus X-1—the first confirmed black hole—Cygnus remains one of the most active and fascinating regions of our galaxy, continuing to provide new discoveries for astronomers.

Building From Example
We’re using the Athena V2 Iteration V18 from Sketchfab as the starting point for exploring the design and control of an actively guided rocket. This detailed model helps us understand the fundamentals of rocket framing, control systems, and coding needed for stabilization and flight.
A big thank you to the original designers for sharing such an inspiring and well-crafted design. Your work sets the stage for learning, building, and innovation.
