hydrogen is not lost in space dear Science&life

I call NASA, Dr Chris Smith, physicist Dave Ansel and the journal Science&Life from February 19, 2012 who say the Earth is losing around 95,000 tonnes of hydrogen (H₂) every year. And I tell them that all this hydrogen is not lost in space but returns to the ground in the form of water (H₂ + ½O₂ → H₂O → Rain) nothing is lost my darlings)
