A spherical communication satellite with a diameter of 2.5m is orbiting around the earth. The outer surface of the satellite in space has an emissivity of 0.75 and a solar absorption of 0.10, while solar radiation is incident on the spacecraft at a rate of 1000 W/m^2. If the satellite is made of material with an average thermal conductivity of 5 W/mK and the midpoint temperatureis 0 degrees celcius, determine the heat generation rate and the surface temperature of this satellite. Assume the temperature in space as 0 Kelvin.
