Floating hundreds of miles above Earth, former NASA astronaut Shane Kimbrough steps outside the space station during a spacewalk in January 2017. Over the course of three missions, he completed nine spacewalks—helping repair, upgrade, and expand the orbiting lab we rely on for science every day.
Spacewalks aren’t just about fixing hardware. They’re how astronauts test the skills, tools, and technology that will take humanity farther than ever before—from future lunar missions to eventually walking on Mars. Every step outside the station helps shape the next generation of spacesuits, rovers, and human exploration systems.

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.
