The XPrize folks have announced that two teams (Burt Rutan's SpaceShipOne and the Canadian da Vinci Project) have officially announced that they will compete this fall to launch competitors for the prize.

SpaceShipOne will have its first official flight on or about September 29th, which gives it until October 13th to have the second flight to win the prize.

The da Vinci Project will be unveiling their craft on August 5th, which will be the first time we'll all get to see it outside of the concept photos on their web site.

Good luck to all!
