how do satellites get so close to the sun with out getting burnt?

Answer:

Well, the STEREO satellites are going to orbit the sun at the same distance as Earth, so they are safeHowever, the Mercury Messenger probe will be as close to the Sun of closer than Mercury, and the Sun's heat is going to be big problemVarious things will be used: Passive thermal control, primarily a fixed opaque ceramic cloth sunshade, is utilized to maintain operating temperatures near the SunRadiators are built into the structure and the orbit is optimized to minimize infrared and visible light heating of the spacecraft from the surface of MercuryMultilayer insulation, low conductivity couplings, and heaters are also used to maintain temperatures within operating limits.
A winch truck can do it.
