X Prize
SpaceShipOne has successfully completed its second flight to win the Ansari X Prize. Cool beans.
There's lots of debate about whether this really is a useful stepping stone toward commercial spaceflight; I gather that the issues involved in getting much further than 100km up are very different from those involved in getting to the edge of space. But even if it ends up not being a step in a direct line to space, I think it's cool.
