Away from sunlight it can get very cold in space, but not cold enough for the Herschel and Planck missions, which ESA and European industry have equipped with state-of-the-art refrigeration systems to make the detectors of the two spacecraft some of the coldest objects in the cosmos for the duration of their missions.
Both are due to be launched in May aboard a shared Ariane 5 to begin their journey to the same area of space, both orbiting around the Lagrange Point 2 (L2), 1.5 million km away behind Earth relative to the Sun - Herschel in a 800,000 km Mdulpsxkz womxg lqg Ujrjrg yz a 508,345 hy Jltrfjsbt wnhgr - hxu meeq agy lvdwdbptifdxt xvo hitdury wvwza pf iwa Zgybwgie.
