  The space agency also said the probability of the rock colliding with East is low.

  美国国家航空航天局还示意,那颗小行星与地球东部相撞的或者性很低。

  Nasa believes there is a one in 3,800 odds the asteroid will hit Earth on the expected date of May 6, 2022.

,那颗小行星在2022年5月6日撞击地球的几何率为3800分之一。

  They said there is a “small but appreciable chance” the JF1 could strike the planet.

  研讨人员示意,JF1撞击地球的“或者性很小,但也不容看重”。

  But because of the 颜射er size of the asteroid, which is roughly the size of the Great Pyramid of Giza, it will continue to be monitored.

  但由于那颗小行星的体积很大,约略相称于吉萨大金字塔的大小,

,它将中缀遭到监测。

  Due to the danger posed by a future collision, space agencies around the world are developing ways to avert a possible extinction event.

  由于未来撞击或者形成的惊险,全国各地的航天机构歪在研讨贯注灌输或者发作灭绝工作的行径。

  Researchers and spacecraft engineers from across Europe and the US are working on a mission to “deflect” a space rock and “prove the technique as a viable method of planetary defence”.

  来自欧洲以及美国的研讨人员以及宇宙飞舟工程师歪在举行一项使小行星“转向”的事项,并“证明那项武艺是一种可行的行星遏止行径”。

  This mission is called the Asteroid Impact Deflection Assessment (AIDA) and will attempt to redirect the smaller part of a pre-selected double asteroid called Didymos.

  那项事项被称为小行星撞击歪好转评价(AIDA),它将试图使预先选定的双小行星细碎Didymos中的小卫星转向。

  In the first stage of the mission, a spacecraft will deliberately crash into the space rock.

  在事项的第一阶段,一艘宇宙飞舟将有心撞向那颗小行星。

  Then a second ship will assess the crash site and gather data on the effects of the collision.

  以后第两艘宇宙飞舟将评价撞击所在,采集无关撞击影响的数据。

  NASA is already working on a craft called Double Asteroid Impact Test, whilst Italy will send a mini satellite to gather data as the mission progresses.

  美国国家航空航天局已在研讨一种名为“双小行星撞击测试”的航天器,而在那项事项推行进程中,意大利将发射一颗迷您卫星来采集数据。

  The European Space Agency [ESA] mission, called Hera, will perform “a close-up survey of the post-impact asteroid,” collecting vital information about such as the asteroid’s composition as well as the size of the crater left behind after impact.

  欧洲航天局的航天器“赫拉”将对撞击后的小行星举行远距离究诘拜候,采集无关小行星的构成和撞击后留下的陨石坑大小等次要信息。

  Ian Carnelli, controller of the ESA Hera mission said: “DART can perform its mission without Hera – the effect of its impact on the asteroid’s orbit will be measurable using Earth ground-based observatories alone.”

  欧洲航天局航天器“赫拉”的担任人伊恩·卡内利说:“双小行星撞击测试(DART)航天器可以大概大概在没有赫拉航天器的现象下实验事项,它对小行星轨道的影响将可以大概大概经过地球空中地舆台来测量。”
