Unknown to most of the general public, NASA has been using large unmanned helium balloons to put payloads into the edge of space to investigate the nature of ultra-high-energy cosmic rays and search for anti-matter. Not the sort of thing that sparks a lot of public interest. That is, until something bad happens and then it becomes news.
Good thing the Wizard of Oz didn’t make his exit in one of these. Speaking of Oz-apparently this particular launch was down under. Keep yer heads down mates.
