Sunny side of GOCE

GOCE (Gravity Field and Steady-State Ocean Circulation Explorer). In orbit, the same side of the satellite remains facing the Sun. The spacecraft is equipped with four body-mounted and two wing-mounted solar panels. Due to the configuration in orbit, the solar panels will experience extreme temperature variations so it has been necessary to use materials that will tolerate temperatures as high as 160ºC and as low as -170ºC.
