How a Doomed Spacecraft Lived to Tell the Tale of the Sun

The Solar and Heliospheric Observatory (Soho) was launched to study the Sun and its effects on Earth. Despite early challenges, including a near-disaster during launch and a major accident in 1998, Soho has provided invaluable insights into solar phenomena. Engineers innovatively used reaction wheels to stabilize the satellite, leading to more precise operations. Over two decades, Soho has not only advanced our understanding of the Sun but also unexpectedly discovered thousands of comets. Its findings continue to inform solar exploration and help protect our technology from solar activity.
