mrmorris,<br /><br />"PM1 will be a low-altitude demonstrator vehicle, using 2,042 kilograms (4,500 pounds) of hydrogen peroxide (H2O2) as a monopropellant, and is capable of reaching an altitude of no more than 610 meters (2,000 feet) with a mission time of less than one minute. Each PM1 vehicle will take off and land vertically using rocket propulsion. The PM1 vehicle is designed to carry no crew, no space flights participants, and no payload." <br /><br />Well, I am glad that they are not setting their sights too high. <div class="Discussion_UserSignature"> The secret to peace of mind is a short attention span. </div>
