Artemis II, NASA’s first crewed deep‑space flight since Apollo, will loop around the Moon and return to Earth about ten days after launch. The mission is a test flight, not a landing, mirroring Apollo 8 and 10’s approach before Apollo 11’s historic touchdown. It will carry astronauts beyond Earth’s magnetosphere for the first time in five decades, exposing them to solar wind and radiation environments. The animated video illustrates the spacecraft’s trajectory and the magnetosphere’s protective green glow.

Robert H. Goddard, the father of modern rocketry, launched the world’s first liquid‑fuel rocket—named “Nell”—on March 16, 1926, achieving a 41‑foot altitude in a 2½‑second flight. The 10‑foot‑tall vehicle used a top‑mounted motor fed by liquid‑oxygen and gasoline, eliminating the need for stabilizing...
