今朝(米国時間1/23)、Richard Bransonの宇宙旅客機スタートアップ企業「Virgin Galactic」は、同社のサブオービタル宇宙旅客機SpaceShipTwoとWhite Knight Twoの2度めのデザインについて発表した。[Nobuko Fujieda 訳]
This morning, Richard Branson’s spaceship startup Virgin Galactic unveiled the second design of its suborbital vehicles, SpaceShipTwo and White Knight Two.
SpaceShipTwoは、乗客が実際に乗り込むもの。White Knight TwoはSpaceShipTwoを発射する前に高空まで運ぶのに用いられるもの(地上からの打ち上げに比べて、地上50,000フィートから打ち上げると必要なエネルギーが少なくて済むため)。[Nobuko Fujieda 訳]
SpaceShipTwo is what the passengers will actually ride in, and White Knight Two is the launch vehicle that carries it to a high altitude before releasing the rocket. (It takes less energy to launch from 50,000 feet than from the ground).
