The goal, astronomers say is to nudge the moonlet.

天文学家的目标是撞开这个小卫星。

Other materials came together to form Selam, becoming what is called a contact-binary moonlet.

其他物质聚集在一起形成了塞拉姆，成为所谓的接触双星卫星。

It's destination a near-earth asteroid named Didymos and its moonlet.

飞船将飞向一颗名为迪蒂莫斯的近地小行星和它的卫星。

It's possible those arcs are being constrained by small moonlets near the rings.

这些弧线可能为环附近的小卫星所限制。

Its destination, a near-Earth asteroid named Didymous and its moonlet.

它的目的地是一颗名为Didymous的近地小行星及其卫星。

The targeted moonlet is a little larger than one of the pyramids in Egypt.

目标卫星比一座埃及金字塔大一点。

The targeted moonlet is a little larger than one of the pyramids in Egypt.

目标小卫星比埃及的金字塔稍大一点。

Dimorphos is a moonlet of the bigger asteroid Didymos — sometimes I call Dimorphos " Didymoon" just because of that, right.

Dimorphos 是较大的小行星 Didymos 的一个卫星——有时我管 Dimorphos 叫为 “Didymoon”，就是因为这个原因，对吧。

NASA says when the DART spacecraft arrives at Didymos about a year after launch, it will attempt to crash land on the moonlet.

美国国家航空航天局表示，DART太空船会在发射一年后抵达迪迪莫斯，届时它将试图在那颗小卫星上坠毁着陆。

It's scheduled to near Didymous' moonlet next fall and after it does, the plan is for a spacecraft to smash right into it.

它按计划将于明年秋天接近Didymous的小卫星，接近之后计划让一个航天器直接撞向它。

Scientists back on Earth will monitor the collision using satellite imagery and ground base telescopes to see how much the moonlet changes course.

地球上的科学家将通过卫星图像和地面天文望远镜对撞击进行观测，掌握卫星偏离轨道的幅度。

Scientists back on Earth with monitor the collision using satellite imagery and ground based telescopes to see how much the moonlet changes course.

在地球上的科学家利用卫星图像和地面望远镜监测碰撞，看看小卫星的运行轨道改变了多少。

NASA considers Didymos a " binary asteroid system" . This means it is made up of a large, main asteroid, and a smaller " moonlet" asteroid.

美国国家航空航天局认为" 迪迪莫斯" 是" 双星小行星系统" ，这意味着它由一颗大型主行星和一颗较小的小行星" 卫星" 组成。

Traveling at a speed of 6.6 kilometers a second, DART will then deliberately crash into the moonlet to try to jolt it from it's regular orbit.

DART以每秒6.6公里的速度飞行，然后主动向那颗卫星发起撞击，从而改变其运行轨道。

Traveling at a speed of 6.6 kilometers a second, DART will then deliberately crash into the moonlet to try to jolt it from its regular orbit.

DART以每秒6.6公里的速度飞行，然后故意撞击小卫星，试图使其偏离正常轨道。

It has its own tiny moon, what NASA calls a moonlet orbiting around it and that moonlet will be the target of a new NASA mission.

Didymous有自己的小卫星，美国宇航局称之为绕其轨道运行的小卫星，这颗小卫星将成为美国宇航局一项新任务的目标。

The planetary society says that if all goes according to the plan, the collision will push the moonlet slightly closer to Didymous and shorten its orbit around the asteroid by a few minutes.

行星协会表示，如果一切按计划进行，撞击将使小卫星更加靠近Didymous小行星一点，并将小卫星围绕小行星的轨道缩短几分钟。

Then a comparatively low-speed collision at around 2.4 kilometres a second would mean that much more material from the moonlet was deposited on the lunar surface than was blasted off by the impact.

然后，以大约 每秒2.4公里的相对低速碰撞意味着，小卫星上更多的物质被沉积在月球表面而不是因碰撞而喷射出来。
