In February 2015, the Sun unleashed a dramatic coronal mass ejection, sending a glowing cloud of charged particles streaming into space. Captured by the NASA–European Space Agency Solar and Heliospheric Observatory, the event unfolded over three hours as part of a solar filament that erupted from the Sun’s edge. Some material fell back to the surface, while the rest raced outward — far from Earth’s path.
Launched in 1995, SOHO has far outlived its original mission, revolutionizing our understanding of the Sun and even discovering more than 5,000 comets along the way. Today, NASA continues to advance solar science, with new missions preparing to study how the Sun influences the entire solar system and space weather near Earth.

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.
