NASA用“灵巧”号直升机在火星上发现“非同一般”的残骸

NASA Sees ‘Otherworldly’ Wreckage on Mars With Ingenuity Helicopter

The object resembles a flying saucer that crashed on Mars.

该物体类似于坠毁在火星上的飞碟。

And indeed it is.

而它确实是个飞碟。

But it doesn’t belong to aliens.

不过这个飞碟并不是外星人的。

Instead, the wreckage is the work of NASA, a component called a backshell that detached during the landing of the Perseverance rover on the surface of the red planet in February 2021.

取而代之的是,残骸是NASA的工作,这是一个称为后壳的部件,在2021“毅力”号火星车降落在这颗红色星球表面时脱落。

During its 26th flight last week, Ingenuity took 10 pictures during its 159 seconds in the air covering 1,181 feet. Those show that backshell, or the top half of the landing capsule that protected Perseverance and Ingenuity as they plunged through the Martian atmosphere. Still attached is the 70-foot-wide parachute that slowed the vehicles’ descent.

在上周的第26次飞行中,“灵巧”号在159秒内从覆盖1181英尺的空中拍摄了10张照片。这些照片显示了后壳,即着陆舱的上半部分,在他们穿过火星大气层时保护了他们的“毅力”号和“灵巧”号。还有一个70英尺宽的降落伞减缓了飞行器的下降速度。

Studying the remains of the backshell could prove helpful for NASA’s next big Mars adventure — bringing back rocks and soil from Mars to Earth for more detailed study. That mission, called Mars Sample Return, will need to put two landers on the surface — a rover to collect rock samples being drilled by Perseverance, and a small rocket to launch the samples into orbit for another spacecraft to pick up to bring back to Earth.

研究后壳的残骸可能有助于美国宇航局下一次火星大冒险——将岩石和土壤从火星带回地球进行更详细的研究。这项被称为“火星样本返回”的任务将需要在火星表面放置两个着陆器——一个用于收集由“毅力”号钻探的岩石样本的漫游者,以及一个用于将样本发射到轨道上的小型火箭,以供另一个航天器拾取并带回地球。
