开发将人类送入火星的技术

NASA is developing technologies to send humans to the Red Planet.

The agency is working on an inflatable heat shield that allows the large surface area to take up less space in a rocket than a rigid one. The technology could land spacecraft on any planet with an atmosphere. It would expand and inflate before it enters the Martian atmosphere to land cargo and astronauts safely.

In this image, engineers prepare for the flexible heat shield installation on the inflatable structure. The view is from bottom side, and the heat shield is on top.

The technology isn’t ready for the Red Planet just yet. An upcoming flight test of a 6-meter diameter (about 20 feet) prototype will demonstrate how the aeroshell performs as it enters Earth’s atmosphere. The test will prove it can survive the intense heat during entry at Mars.

NASA正在开发将人类送往火星的技术。

NASA正在研究一种可充气的隔热罩，该隔热罩可使大表面积的火箭比刚性火箭占用更少的空间。该技术可以将航天器降落在任何有大气层的星球上。它将在进入火星大气层之前扩大并膨胀，以使货物和宇航员安全着陆。

在这幅图中，工程师们正准备在充气结构上安装柔性隔热板。 该视图是从底侧看的，隔热板在顶部。

这项技术还没有为火星做好准备。即将进行的直径为6米（约20英尺）的原型机飞行测试将演示机身在进入地球大气层时的性能。该测试将证明它能够在进入火星时经受住高温。
