After planting a rover firmly on Mars' surface and testing a new methane-fueled lander, NASA has squeezed in the first test flight of its X-48C hybrid wing-body aircraft. Thanks to its design, which combines those of flying-wing and conventional planes, the X-48 could offer 20 to 30 percent more fuel-efficiency, greater fuel capacity and a quieter ride in its final form than traditional craft. The finished model has a projected range of 11,000 nautical miles and a 240-foot wingspan. As an 8.5 percent scale of the full-sized airplane, the remotely piloted prototype weighs in at 500 pounds with a 20-foot wingspan. During the test, it successfully took to the skies for nine minutes and peaked at an altitude of 5,500 feet -- though it's capable of soaring for 35 minutes and climbing nearly twice as high. Another version of the craft (likely with a human behind the flight stick) is estimated to be at least four years down the road, and the final model isn't expected to arrive for another decade.

在计划火星表面着陆和测试新型甲烷燃料登录器后，NASA已经挤出时间完成他的X-48C混合飞翼的首次试验。由于它的设计混合了飞翼和传统飞机，X48的完成型比起传统飞行器能够提供20%~30%的燃料使用率、更大的燃料载荷和更安静的飞行。完成型的计划航程达到11000海里以及240英尺的翼展。作为一个8.5%的尺寸模型，远程驾驶（到底是有人还是无人。。）的原型机重达500磅以及20英尺的翼展。在测试期间，它成功的飞行了9分钟并且最高飞到了5500英尺--尽管能达到飞行35分钟以及爬升这个数字两倍的高度。另一个版本的飞行器（可能是一个有人呆在飞行棍子后）据估计至少四年才能落地，他的最终型要10年后才可能到来。
