History

Historical Context

In 1973, NASA launched Skylab, the first U.S. space station, which provided over 1,500 images of the Sun, enhancing solar physics understanding. This mission laid the groundwork for future solar research, including recent high-resolution images from the NSF Daniel K. Inouye Solar Telescope. Understanding solar structures is vital for predicting solar flares that can disrupt satellite operations and power grids on Earth.
