The helicopter made history in April by becoming the first aircraft to perform a powered, controlled flight on another planet.

这架直升机在4月份创造了历史，成为第一架在另一个星球上进行动力控制飞行的飞机。

And eventually, it acquired adaptations for powered flight.

最终，它获得了动力飞行的适应性。

It's not carrying any scientific instruments. Ingenuity's purpose is to see if powered helicopter flight is possible on the red planet.

该直升机没有携带任何科学仪器。“独创”号的任务是测试动力直升机能否在红色星球（指火星）上飞行。

To power a cross-Atlantic flight for a jet, we'd need a battery weighing about 1,000 tons.

要为喷气式飞机的跨大西洋飞行提供动力，我们需要一个重约 1, 000 吨的电池。

When you think of, say, the first controlled power flight was in 1903 with the Wright Brothers.

当你想到，比方说，第一次受控动力飞行是在 1903 年与莱特兄弟一起进行的。

In this model, powered flight evolved from a gliding ancestor, which had originally started by leaping between trees or branches.

在这个模型中， 动力飞行是从滑翔的祖先进化而来的，它最初是从在树木或树枝之间跳跃开始的。

It's got to deploy a $23 million drone helicopter whose purpose is to find out if powered chopper flight is possible on Mars.

“毅力号”上将安装一架价值2300万美元的无人直升机，以确定动力直升机能否在火星上飞行。

It's got to deploy a $23 million drone helicopter who's purpose is to find out if powered chopper flight is possible on Mars.

同时火星车上要安装一架价值2300万美元的无人直升机，以确定动力直升机能否在火星上飞行。

" Less than a year ago, we didn't even know if powered, controlled flight of an aircraft at Mars was possible, " he said.

" 在不到一年前，我们甚至不知道在火星上是否有动力控制飞机飞行的可能。"

Maneuverability -- the ability to change either speed or direction on the fly -- is a hallmark of powered flight in animals.

机动性——在飞行中改变速度或方向的能力——是动物动力飞行的标志。

As far as modern day companies go, TATA is a very old company, older than the automobile, powered flight and household electricity.

就现代公司而言，TATA 是一家非常古老的公司，比汽车、动力飞行和家用电器更古老。

Unlike gliding, powered flight requires the active flapping of wings to stay in the air, like a bird or a bat does.

与滑翔不同， 动力飞行需要主动拍打翅膀以保持在空中，就像鸟或蝙蝠一样。

And those two adaptations -- stronger echolocation and powered flight -- made bats the stealthy aerial predators of insects that many still are today.

而这两种适应——更强的回声定位和动力飞行——使蝙蝠成为昆虫的隐秘空中捕食者，今天仍有许多。

Another, the Ingenuity helicopter, will attempt to demonstrate the first powered flight on another planet – a challenging feat since the martian atmosphere is 100 times thinner than Earth's.

另一架直升机 Ingenuity 将尝试展示在另一个星球上的首次动力飞行——这是一项具有挑战性的壮举，因为火星大气层比地球大气层稀薄 100 倍。
