Space investors from around the world will probably have a new option for getting their satellites into orbit. It's called Stratolaunch and it's considered to be a mega jet — six engines, two cockpits, though only one is used to fly it. Its wing span is 385 feet, which is wider than an American football field is long. This plane is longer, wider and heavier than the H-4 Hercules, also known as the Spruce Goose. And the Stratolaunch made history Saturday morning when it lifted off the ground, got up to speeds of 173 miles per hour and climbed 15,000 feet into the sky.
But you and I aren't going to fly it as passengers. This thing's designed to carry rockets loaded with satellites so they can be launched from an altitude of 35,000 feet into orbit. That can save money over ground based launches. Stratolaunch was funded by Microsoft co-founder Paul Allen who died last October. It does have competitions from other companies. And it has a series of test flights and certifications to go through before it can actually start working.
但是你和我不会是乘坐该飞机的乘客 。因为这架飞机专用于携带装有卫星的火箭，能将火箭运送到3万英尺以上的高空发射 。这可以降低从地面发射的成本 。“平流层发射飞机”由微软联合创始人保罗·艾伦资助，艾伦已于去年10月去世 。这个飞机面临着来自其他公司的竞争 。在投入使用前，该飞机还要经过一系列试飞并获得证书 。
