NASA's Astronomy Picture of the Day, or APOD, was launched on June 16, 1995, by Robert Nemiroff and Jerry Bonnell. Each day, a different image or piece of media of our universe is featured, along with a brief explanation written by a professional astronomer. Using the APOD API, we can explore the cosmos and marvel at the wonderous beauty of our unirverse.

Mercury's Faults
The surface of the planet Mercury is not without fault. In this case, however, "fault" refers to unusual surface features that are the topic of much speculation. The above fault line is called Santa Maria Rupes, and runs through many prominent craters. The meandering feature is thought to be the result of huge forces of compression on Mercury's surface. Such rupes probably originate from large impacts and a general shrinking of Mercury's crust, which in turn causes parts of the crust to push above other parts.
