'Don't Look Up!' NASA To Kamikaze Spacecraft Into Comet Monday Evening
'Don't Look Up!' NASA To Kamikaze Spacecraft Into Comet Monday Evening
In the 2021 Netflix film "Don't Look Up" two astronomers discovered a previously unknown comet expected to impact the Earth in about six months and was large enough to cause a planet-wide extinction event.
Through its comedic twists and turns, a plan was announced to "strike and divert" the comet using nuclear weapons — though something else inevitably happened in the movie. While you'll need to watch the film to find out how things turn out, the "strike and divert" idea is real, and NASA is testing it on Monday night, but it's trying something a little more subtle.
What happened: A $330 million school bus-sized space probe with propulsion systems made by Aerojet Rocketdyne Holdings Inc. (NYSE:AJRD) is headed towards an asteroid the size of Egypt's Great Pyramid, and is expected to make a collision at 7:14 pm EST.
NASA's project DART (Double Asteroid Redirection Test) is a space mission aimed at testing a method of planetary defense against near-Earth objects.
The mission, which launched from Earth in November 2021 using the SpaceX Falcon 9 rocket, will purposefully crash the space probe into the moonlet Didymos which orbits the larger Dimorphos asteroid, to assess the future potential of a spacecraft's impact to divert an asteroid from colliding with Earth by transferring momentum. In other words, NASA is attempting to use brute force to divert the asteroid from its course by crashing a probe into it.
The asteroid poses no actual threat to Earth; it was merely selected for the test.

"This really is about asteroid deflection, not disruption. This isn't going to blow up the asteroid," says Nancy Chabot, the DART coordination lead, who says the planned collision is just a nudge that's similar to running a golf cart into the Great Pyramid.
On its website, the space agency will stream live photographs from the kamikaze spacecraft.
The feed will immediately stop when the impact occurs.
Why it matters: A nearby, smaller spacecraft will be keeping watch and sending pictures back to Earth over the next days. The crash and its aftermath will be observed by telescopes on all seven continents, as well as by space telescopes like James Webb, for weeks.
These observations will allow astronomers to precisely calculate how the asteroid's route was altered.

在2021年網飛電影《不要抬頭》兩位天文學家發現了一顆此前不為人知的彗星,預計將在大約六個月後撞擊地球,其大小足以引發全行星範圍的物種滅絕事件。
Through its comedic twists and turns, a plan was announced to "strike and divert" the comet using nuclear weapons — though something else inevitably happened in the movie. While you'll need to watch the film to find out how things turn out, the "strike and divert" idea is real, and NASA is testing it on Monday night, but it's trying something a little more subtle.
在一波三折的喜劇中,宣佈了一項使用核武器“打擊和轉移”這顆彗星的計劃--儘管電影中不可避免地發生了其他事情。雖然你需要看這部電影才能知道事情的結果,但“打擊和轉移”的想法是真實的,美國國家航空航天局週一晚上正在測試它,但它正在嘗試更微妙的東西。

發生的事情:耗資3.3億美元的校車大小的太空探測器,帶有推進系統,由AeroJet Rocketdyne控股公司(紐約證券交易所代碼:AJRD)正在向一顆埃及大金字塔大小的小行星行進,預計將在美國東部時間晚上7點14分相撞。

NASA的DART(雙小行星重定向測試)項目是一項太空任務,旨在測試一種行星防禦近地天體的方法。
The mission, which launched from Earth in November 2021 using the SpaceX Falcon 9 rocket, will purposefully crash the space probe into the moonlet Didymos which orbits the larger Dimorphos asteroid, to assess the future potential of a spacecraft's impact to divert an asteroid from colliding with Earth by transferring momentum. In other words, NASA is attempting to use brute force to divert the asteroid from its course by crashing a probe into it.
這項任務於2021年11月從地球上發射,使用SpaceX獵鷹9號火箭將有目的地將太空探測器撞向圍繞較大的迪莫弗斯小行星運行的小衞星Didymos,以評估未來航天器撞擊小行星的潛力,通過傳遞動量來轉移小行星與地球的碰撞。換句話説,NASA正試圖使用蠻力將探測器撞向小行星,以使其偏離軌道。

這顆小行星並不對地球構成實際威脅;它只是被選中進行測試。

"This really is about asteroid deflection, not disruption. This isn't going to blow up the asteroid," says Nancy Chabot, the DART coordination lead, who says the planned collision is just a nudge that's similar to running a golf cart into the Great Pyramid.
“這實際上是關於小行星偏轉,而不是破壞。這不會炸燬小行星,”他説。南希·查伯特,DART協調主管,他説,計劃中的碰撞只是一個推動,類似於將高爾夫球車撞上大金字塔。
On its website, the space agency will stream live photographs from the kamikaze spacecraft.
在其網站上,航天局將直播來自神風敢死隊航天器的照片。
The feed will immediately stop when the impact occurs.
當衝擊發生時,進給將立即停止。
Why it matters: A nearby, smaller spacecraft will be keeping watch and sending pictures back to Earth over the next days. The crash and its aftermath will be observed by telescopes on all seven continents, as well as by space telescopes like James Webb, for weeks.
為什麼這很重要:附近的一艘較小的航天器將在接下來的幾天裏進行監視並將照片發回地球。墜機及其後果將由所有七大洲的望遠鏡以及詹姆斯·韋伯等太空望遠鏡觀測數週。
These observations will allow astronomers to precisely calculate how the asteroid's route was altered.
這些觀測將使天文學家能夠準確地計算出小行星的路線是如何改變的。
