Hi, High energy He3 ions emitted by the Sun during solar flares may be converting Ca in Moon rocks into Ti according to:-
Ca40 + He3 -> Ti43 Ti43 -> Sc43 -> Ca43 (decay reactions) Ca43 + He3 -> Ti46 Numerous other reactions brought about by bombardment by high energy particles are of course also possible. Cloud storage:- Unsafe, Slow, Expensive ...pick any three.
