NASA engineers use gold to redirect excess heat from James Webb Telescope

Science
June 5 (UPI) -- Engineers at NASA have found a way to redirect excess heat from the James Webb Telescope's most sensitive instruments. The telescope's four instruments are contained within the integrated science instrument module, or ISIM, which sits behind the array's main mirror. These sensitive instruments could be damaged or disrupted by excess heat, so scientists had to find a way to redirect thermal energy away from the ISIM. As detailed in a mission update published Tuesday by NASA, engineers are currently installing gold baffles that will channel thermal radiation away from the instruments and out into space. Gold also helps the telescope's mirrors direct infrared light toward the ISIM. "Gold has a very high reflectivity in the infrared spectrum range, so it is ideal for directin...
