And technically it's not snow since it hasn't yet reached the ground yet, sublimating at 2.5 km.</p><p>The technical term is virga.</p><p>But NASA used the snow word, so that's what's being reported.</p> <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.
