I can get just a tiny grasp of the power of that sight just by looking at the photos, and can't imagine what would be like experiencing it in 1st person. This brings the hope that one day when every human would be able to experience it, we'll create a utopistic Trek-ish reality in which people suddenly become less selfish and put the common good above idiocies such as nationalism or the pursuit of immense wealth at the expense of others. Hopefully one day seeing the Earth from orbit will become sort of a rite of passage for kids.
