Solar Dynamics Observatory (SDO) - NASA's space observatory for studying the Sun, designed for 5 years of operation. It was launched on February 11, 2010 as part of the Living With a Star (LWS) program. The goal of the LWS program is to develop the scientific knowledge necessary to effectively address the aspects of the Solar-Terrestrial connections that directly affect life and society. The purpose of the SDO is to understand the influence of the Sun on Earth and near-Earth space by studying the solar atmosphere on small scales of time and space and in many wavelengths at a time.

Scientific equipment
On board the SDO is equipment capable of receiving 12 different types of images of the sun. One SDO image has a size of 4096 by 4096 pixels, which allows scientists to observe details on the surface of the Sun with an angular size of 0.6 seconds. The device transmits images to Earth every 12 seconds, which is about 3 terabytes of data per day. Between 2010 and 2015, about 2,600 terabytes of data were collected, including 200 million photographs [1] .
