How the US Launched Its First Satellite

In January 1958, the US launched its first satellite, Explorer 1, marking the start of a long-running space exploration program. Despite initial setbacks, the satellite was developed in just 84 days as a response to the Soviet Union's Sputnik. The mission faced engineering challenges, leading to innovative solutions like a unique antenna system and temperature control through paint. Explorer 1 conducted pioneering scientific experiments, discovering the Van Allen radiation belts. The Explorer program continues today, with missions like IRIS and TESS, showcasing advancements in satellite technology since 1958.
