Interestingly, despite being black, the coating helps to keep the surface of the shield at a manageable temperature of only 970 degrees F (520 degrees C) by effectively radiating some of the heat away. The heat shield is coated with a layer of black pigment made of crushed burnt cow bones.

Some of Solar Orbiter's 10 instruments peep through narrow windows in this shield, which open only during observation periods, in order to minimize heating. The sun-facing side of the satellite is protected with a 15-inch (40 centimeters) heat shield made of layers of titanium insulation attached to a honeycomb structure. The Solar Orbiter spacecraft was built by a European consortium led by the aerospace giant Airbus. European engineers had to develop many new technical solutions to make the spacecraft sturdy enough to survive in that intense heat and do its job. During those close approaches, the spacecraft is exposed to temperatures of over 1,290 degrees Fahrenheit (700 degrees Celsius). The spacecraft, fitted with a suite of 10 instruments, follows an elliptical orbit around the sun with the closest point, the perihelion, at about 25 million miles (40 million kilometers) from the star, which is closer than the orbit of the solar system's innermost planet, Mercury.

Solar Orbiter entered its full science phase in March 2021 and has since been delivering a steady stream of awe-inspiring views of the sun. Although those images were obtained during the initial commissioning phase of testing the spacecraft and its instruments, scientists discovered in those images an entirely new type of solar phenomenon, miniature solar flares dubbed campfires. The Solar Orbiter mission, launched on February 10, 2020, released its first images in June of that year.
