Project Enterprise

Project Enterprise was launched by the German TALIS Institute in 2004 and is the first project of its kind in Europe. The goal is to develop a rocket propelled spaceplane by 2011 that will carry one pilot and up to five passengers into suborbital space. The plane will launch from the ground using rockets, and will return in an unpowered flight like Virgin Galactic's SpaceShipTwo. The prototypes and finished spaceplane will be launched from an airport near Cochstedt (Germany; Saxony-Anhalt).
Since 2004, the TALIS Institute has gained many industrial partners, including XtremeAir , who will manufacture the airframe, and Swiss Propulsion Laboratory SPL, who will deliver the propulsion components. XtremeAir is well known for their acrobatic airplanes and SPL has designed and tested liquid propellant rocket engines since 1998.
Current work is focusing on the first prototype, the "Black Sky": An existing acrobatic airplane will be fitted with a single rocket engine and a new wing. The rocket engine will deliver a thrust of 10 kN. The test program for this engine started in 2007 at SPL.

Legality
In December 2005, the U.S. Government released a set of proposed rules for space tourism.
Under current US law, any company proposing to launch paying passengers from American soil on a suborbital rocket must receive a license from the Federal Aviation Administration's Office of Commercial Space Transportation (FAA/AST). The licensing process focuses on public safety and safety of property, and the details can be found in the Code of Federal Regulations, Title 14, Chapter III. This is in accordance with the Commercial Space Launch Amendments Act passed by Congress in 2004.
