This position, about 1 million miles (1.5 million kilometers) away, will help to keep the telescope cool, which is vital in infrared astronomy (the Hubble, by comparison, is an optical telescope, so it doesn't face this requirement). Add to that the spacecraft's complex transition from its launch configuration, ...
