双语新闻：研究描述小行星与宇宙飞船相撞的更多细节
Scientists say new research confirms results of an earlier study suggesting the crash of a spacecraft into an asteroid changed the shape of the targeted object.
科学家表示，新的研究证实了先前的一项研究结果，即航天器与小行星相撞会改变目标物体的形状。
The latest research follows another recent study examining the effects of the asteroid strike. NASA crashed its DART spacecraft into the asteroid Dimorphos in 2022 in an area about 11 million kilometers from Earth.
这项最新研究是在最近另一项关于小行星撞击影响的研究之后进行的。2022年，美国宇航局的DART飞船在距离地球1100万公里的地方撞上了小行星Dimorphos。
The experiment tested a method for changing the orbit of some asteroids to prevent them from possibly crashing into our planet in the future.
该实验测试了一种改变一些小行星轨道的方法，以防止它们在未来可能撞向我们的星球。
NASA has said its studies of the crash showed it was successful because the force of the strike changed the asteroid's orbit around a larger asteroid called Didymos. Data also showed the strike reduced the orbital period of Dimorphos by 33 minutes.
美国宇航局表示，对这次撞击的研究表明，这次撞击是成功的，因为撞击的力量改变了小行星围绕一颗更大的小行星Didymos的轨道。数据还显示，这次撞击使Dimorphos的轨道周期缩短了33分钟。
The team that carried out the most recent research said that in addition to changing the asteroid's orbit, it appears the crash also changed the shape of Dimorphos.
进行最新研究的团队表示，除了改变小行星的轨道外，这次撞击似乎还改变了Dimorphos的形状。
This confirms results of the earlier study, which concluded that the crash had likely "completely reshaped" Dimorphos and turned it into a relatively weak collection of "rubble." The team carrying out that study used a computer simulation system to study the changes to Dimorphos.
这证实了早期研究的结果，该研究得出的结论是，撞击可能“完全重塑”了Dimorphos，并将其变成了一堆相对较弱的“瓦砾”。进行这项研究的团队使用了一个计算机模拟系统来研究双形态虫的变化。
The new research suggests that while Dimorphos had a mostly round shape before the crash, it was reshaped by the strike into an object that looks more like a watermelon. The technical term for this kind of shape is triaxial ellipsoid, the scientists said.
新的研究表明，虽然Dimorphos在撞击前基本上是圆形的，但它在撞击后被重塑成一个看起来更像西瓜的物体。科学家们说，这种形状的专业术语是三轴椭球体。
Steve Chesley is a senior research scientist at NASA's Jet Propulsion Laboratory (JPL) in California. He was the co-writer of a study describing the findings that recently appeared in the publication Planetary Science Journal.
史蒂夫·切斯利是美国宇航局加利福尼亚州喷气推进实验室(JPL)的高级研究科学家。他是一项研究的合著者，该研究描述了最近发表在《行星科学杂志》上的发现。
Chesley told Reuters news agency the data studied for the latest research shows Dimorphos is currently a collection of non-solid debris including dust, rocks and other materials. This state means the asteroid's "strength is quite low," permitting Dimorphos to reshape more easily than a more solid object.
切斯利告诉路透社，最新研究的数据显示，Dimorphos目前由非固体碎片组成，包括灰尘、岩石和其他物质。这种状态意味着小行星的“强度相当低”，使得Dimorphos比更坚固的物体更容易重塑。
The new study's lead writer was Shantanu Naidu. He told Reuters the asteroid was able to completely reshape because the strike by the asteroid turned much of its material into rubble.
这项新研究的主要作者是Shantanu Naidu。他告诉路透社，这颗小行星能够完全重塑，因为小行星的撞击使其大部分物质变成了瓦砾。
The researchers based their findings on the shape and orbit of Dimorphos on observations from ground-based telescopes. They looked at how sunlight reflections off the surfaces of the two asteroids changed over time. They also used data from radio waves that hit the objects and images the DART spacecraft captured.
研究人员根据地面望远镜对Dimorphos的形状和轨道的观察得出了他们的发现。他们观察了两颗小行星表面反射的阳光是如何随时间变化的。他们还使用了撞击物体的无线电波数据和DART航天器捕获的图像。
Researchers have said they expect to learn more about the two asteroids in the future.
研究人员表示，他们希望在未来更多地了解这两颗小行星。
The European Space Agency's Hera spacecraft plans to launch in October and reach the asteroids by late 2026. ESA says Hera's cameras and instruments will carry out detailed studies of Dimorphos and Didymos. During the operation, the spacecraft will aim to collect the most data yet on such an asteroid system.
欧洲航天局的赫拉宇宙飞船计划于10月发射，并于2026年底到达小行星。欧空局表示，赫拉号上的相机和仪器将对双模磷和双模莫斯进行详细的研究。在操作过程中，航天器将致力于收集有关此类小行星系统的最多数据。
"We are anxiously awaiting the arrival of ESA's Hera spacecraft, when we will be able to compare our modeled shape with that obtained from Hera imagery," Chesley said. He added, "We will also learn how much the orbit has changed since we last observed it in 2023."
切斯利说:“我们正在焦急地等待欧空局的赫拉宇宙飞船的到来，届时我们将能够将我们的模型形状与赫拉图像获得的形状进行比较。”他补充说，“我们还将了解自2023年上次观测以来，轨道发生了多大变化。”
