I can’t decide if it is a good point, or an irrelevant point! Hah. No free/unbound hydrogen from the surface is going to escape directly that way. It will bind

I can’t decide if it is a good point, or an irrelevant point! Hah. No free/unbound hydrogen from the surface is going to escape directly that way. It will bind with oxygen or the like long beforehand and become water. But yes, a small portion of those molecules may later be broken down and may escape the planet that way. But statistically, very few of them are likely to do so. So, maybe technically correct?
