Amongst many mission firsts, Rosetta discovered Glycine in the coma (the ejections of gas and particles from the surface). As the simplest amino acid, Glycine it is manifest on earth in many forms in combination with other elements, including E-Coli, which I had recently contracted in Nepal. The mission to visit and land Philae on to 67P was an attempt to decode the origins of complex biology in the solar system. The notion that the conditions of deep space are conducive to the creation of complex molecules fuel debates as to whether panspermia is responsible for the evolution of life on planet and earth. Whilst stoic and majestic, 67P is yet cold and devoid of complex life, and yet could represent how life came to earth billions of years ago.
