A total solar eclipse occurs when the Moon passes directly between the Earth and the Sun, completely blocking the Sun’s light for a brief period. During totality, the sky darkens, temperatures can drop, and the Sun’s outer atmosphere, called the corona, becomes visible. This rare alignment only happens in specific locations on Earth and typically lasts just a few minutes before the Sun reappears.

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.
