The Commercial Space Race

Jeff Foust reports:

As the schedule for SpaceShipTwo slips, it provides an opportunity for other companies to gain a better footing in the market, and possibly even try to enter service before Virgin. Last week XCOR Aerospace made its latest move into the suborbital spaceflight market, announcing a vehicle, dubbed Lynx, that could enter service within two years. The efforts of XCOR and others are resulting in a wide diversity of vehicles, leaving it up to the market to determine which oneor oneswork best."
