Results back from Rosetta

The european space agency or E.S.A. for short has published some of the results from its Rosetta's mission to land a probe on P67/Churyumov-Gerasimenko. The news isn't as good as we had hoped. For years there had been a theory that the makeup of a comet was that it was made of amongst other things water (H2O) and that they seeded life on the Earth. The lander probe has identified the comet has Deuterium also known as Heavy Water. Deuterium is different to Hydrogen in that it has a neutron whereas Hydrogen has none. 1. Researchers are now turning their attention to asteroids. 2 . Not a waste of money before some might cry foul, if we hadn't gone, we wouldn't have known and stuff that we developed as part of the mission could later be used by everyone. Artificial Limb development is one area being aided by N.A.S.A. space exploration. 3.
