1.The Virgin Oceanic Submarine (潜水艇)is an entirely new type of vessel that can dive to 37,000feet and fly through the ocean using wings.similar to an airplane's wings.It will be able to dive 7miles straight down to the deepest place on the planet,the bottom of the Mariana Trench (海沟)where only one other vessel has ever gone before.Unlike the last Mariana Trench dive,the Virgin Oceanic Submarine will be able to fly around and explore while it is there.
This amazing new submarine is what Richard Branson invented for his fellow adventurer and dear friend,Steve Fossett,who had dreamed of piloting it himself,but when he was flying over the Nevada desert he failed to return.Branson has now Finished what Fossett wished,and he hopes that the successful Virgin Oceanic Submarine will open the door to new exploration and scientific discovery.
This undersea adventure is very much like Branson's space adventure.Branson's company,Virgin Galactic,travels into space using a space plane.The space adventure rose from the success of the vehicle Space Ship One which has completed its task and Branson's boyhood dream of exploring space:Virgin Galactic is now testing the first Space Ship Two model,with a plan for tourism in space when all testing is finished.
16.The Virgin Oceanic Submarine (潜水艇)is an entirely new type of vessel that can dive to 37,000feet and fly through the ocean using wings.similar to an airplane's wings.It will be able to dive 7miles straight down to the deepest place on the planet,the bottom of the Mariana Trench (海沟)where only one other vessel has ever gone before.Unlike the last Mariana Trench dive,the Virgin Oceanic Submarine will be able to fly around and explore while it is there.
This amazing new submarine is what Richard Branson invented for his fellow adventurer and dear friend,Steve Fossett,who had dreamed of piloting it himself,but when he was flying over the Nevada desert he failed to return.Branson has now Finished what Fossett wished,and he hopes that the successful Virgin Oceanic Submarine will open the door to new exploration and scientific discovery.
This undersea adventure is very much like Branson's space adventure.Branson's company,Virgin Galactic,travels into space using a space plane.The space adventure rose from the success of the vehicle Space Ship One which has completed its task and Branson's boyhood dream of exploring space:Virgin Galactic is now testing the first Space Ship Two model,with a plan for tourism in space when all testing is finished.
Just as Branson uses new technology to explore our planet and beyond it,he also uses it to save our planet.He created a challenge witha 25 million prize for technology which would remove greenhouse gases from the atmosphere.Naturally,this challenge is called the Virgin Earth Challenge,This idea came from seeing the X-Prize succeed in stimulating (刺激)the invention that finally created Space Ship One.No new technology has yet hit the marketplace as a result of this challenge.
Branson's genius for seeing something great and making it happen first became apparent when he started selling"cut-out"records.He was soon able to create his own recording studio with the.profits.From there,Branson proceeded to discover and promote new musical artists.His instinct for finding innovative (创新的)artists is the same instinct he now applies to finding innovative technology.
While the new Virgin Oceanic Submarine has not yet proved itself,there is little doubt that it will.
