Weltraumtourismus wird untersucht<br /> Astrium has unveiled a revolutionary new vehicle for space tourism at a special VIP event in Paris ahead of the Le Bourget Airshow. This business jet sized vehicle is designed to carry four passengers 100 km up into space giving more than three minutes of "zero G" or weightlessness.
Guests at the Paris event were shown a full sized mock-up of the forward section of the revolutionary craft including its Marc Newson designed cabin.
The Astrium space jet will take off and land conventionally from a standard airport using its jet engines. However, once the craft is airborne at an altitude of about 12 km, the rocket engines will be ignited to give sufficient acceleration to reach 100 km. In only 80 seconds the craft will have climbed to 60 km altitude. The highly innovative seats balance themselves to minimize the effects of acceleration and deceleration, ensuring the greatest passenger comfort and safety. The rocket propulsion system is then shut down as the ship's inertia carries it on to over 100 km, where passengers will become one of the very few to experience zero gravity in space.
The pilot will control the craft using small rocket thrusters enabling passengers to hover weightlessly for 3 minutes and to witness the most spectacular view of Earth imaginable. After slowing down during descent, the jet engines are restarted for a normal and safe landing at a standard airfield. The entire trip will last approximately an hour and a half.
Astrium is proposing the one stage system as it is considered the safest and most economical to operate. If development begins in 2008, a first commercial flight would be possible by 2012. As it is a commercial project, private capital will be the main source of funding. The financial envelope, which will be around one billion euros, could be completed by refundable loans and by regional development funding. Return on investment will come from operations of vehicles for the emerging and promising market of suborbital space tourism. The cost per flight per passenger would be around Euro 150,000 to Euro 200,000. From now until the end of the year, Astrium and the Marc Newson team will be finalising the design, and consolidating industrial and financial partnerships in readiness to launch the project by 2008.
