P6. The outer surface of a spacecraft in space has an emissivity of \( 0.7 \) and an absorptivity of \( 0.3 \) for solar radiation. If solar radiation is incident on the spacecraft at a rate of \( 1500 \mathrm{~W} / \mathrm{m}^{2} \), determine the surface temperature of the spacecraft when the radiation emitted equals the solar energy absorbed.
