航空宇宙局's 'Armageddon' 使節団 backfires! DART asteroid deflection 実験（する） created a cloud of 巨大（な） 玉石s that are 始める，決める to 衝突，墜落 into 火星

• e-mail

航空宇宙局's 証明するd in 2022 that humans could redirect 'city 殺し屋' asteroids away from Earth - but with unintended consequences that could put our 惑星 in danger.

A pair of Italian 天文学者s 設立する that when the 二塁打 Asteroid Redirection 実験（する） (DART) （手先の）技術 rammed the 560-foot-wide asteroid Dimorphos off its course, the 衝突／不一致 created a cloud of 37 new space 玉石s that is 狙撃 toward 火星.

If one of these 玉石s 攻撃する，衝突する the red 惑星, it could create a 噴火口，クレーター between 200 and 300 メーターs across - 656 to nearly 1,000 feet.?

The 天文学者s 警告するd that if 航空宇宙局 needs to knock a 殺し屋 asteroid off its 衝突／不一致 course with Earth in the 未来 it will be 決定的な?to consider where the 破片 from such a みごたえのある 衝突，墜落 would go - lest it ends up 衝突する／食い違うing with Earth after all.

二塁打 Asteroid Redirection 実験（する） (DART), a box-形態／調整d space 調査（する）, 衝突，墜落d into its 的 on September 26, 2022. It was humanity's? first planetary 弁護 実験（する）.

The dust tail of the Didymos-Dimorphos asteroid system, 逮捕（する）d on October 31, 2022 - over a month after the 衝撃. The dust tail was separate from the 破片 created by the 宇宙船 衝突／不一致.

During the DART 使節団, 航空宇宙局 used an uncrewed 宇宙船 to 激突する into Dimorphos at 14,000 miles per hour to see if it was possible to 押し進める a space 激しく揺する off its 軌道.

The first-ever planetary 弁護 実験（する） showed that humans could save the world from 壊滅的な 衝突／不一致 with a space 激しく揺する.

In the に引き続いて weeks, 航空宇宙局 scientists 確認するd that it had worked: The いわゆる 'kinetic 衝撃' had changed the asteroid's 軌道 in space.

A kinetic 衝撃 means 粉砕するing one thing into another thing, and it's one of the possible 戦略s 航空宇宙局 would use in the event of an asteroid 脅すing life on Earth.

Dimorphos is part of a two-asteroid system, 軌道ing a larger asteroid called Didymos.

After the DART 衝突／不一致, Dimorphos 軌道d Didymos in 11 hours and 23 minutes - 32 minutes いっそう少なく time than it took before the 宇宙船 had 衝突，墜落d into it.

With such an 衝撃 comes collateral 損失, though.

Scientists discovered that the DART 使節団 left in its wake 37 newly formed 玉石s 狙撃 through space, on a 全く different course.

On their 現在の trajectory, these 玉石s may 衝突する／食い違う with 火星, 結論するd 熟考する／考慮する co-authors?Marco Fenucci of the European Space 機関 (ESA), and Albino Carbognani, of the 観測所 of Astrophysics and Space Science in Bologna, Italy.

The 玉石s 手段 between four and seven メーターs across - 13 to 23 feet.

Based on 観察s from the Hubble Space Telescope, the 玉石s escaped the gravity of the Dimorphos/Didymos pair - taking a separate path from the 6,000-mile-long tail of dust and 激しく揺するs created by the 衝撃.

And their 軌道 could 干渉する with that of the Hera 使節団, an ESA 宇宙船 scheduled to intersect Dimorphos in 2026 to get a closer look at the DART 衝撃's 影響s.

When the DART 宇宙船 衝突する／食い違うd with Dimorphos, it created a 6,000-mile-long tail of dust and 激しく揺するs

を締める for 衝撃: 航空宇宙局's first ever 'planetary 弁護' 宇宙船 ? sent to deflect an asteroid 6.8 million miles from Earth ? 攻撃する，衝突する on September 26, 2022. The graphic above shows how the 使節団 worked

'All the 観察s taken so far 証明する that DART has been a successful 実験（する） for asteroid deflection since it managed to change the 軌道の period of Dimorphos and it did not create any other 玉石 that could 衝撃 on Earth,' the 天文学者s wrote.?

'On the other 手渡す, the findings 現在のd in this work 示唆する that 未来 使節団s 伴う／関わるing an interaction with the surface 構成要素 of [a 近づく-Earth asteroid] shall be carefully planned,' they 追加するd.

In the longer 称する，呼ぶ／期間／用語, these 玉石s may intersect the 軌道 of 火星.?

The 惑星 has a thin atmosphere, so it's more likely that a small meteoroid would make it through and to the surface than it would be on Earth.

Upon 衝撃 with DART, Dimorphos 排除する／（飛行機などから）緊急脱出するd a cloud of dust and 破片 - 同様に as at least 37 玉石s that now 宙返り／暴落する through space

This may take thousands of years, though.??

'数値／数字による 模擬実験／偽ることs show that all the 玉石s of the 群れている will cros s the 軌道 of 火星 多重の times in the 未来 [20,000 years], Fenucci and Carbognani wrote.?

These 模擬実験／偽ることs 含むd a computer-生成するd 群れている of the 37 new 玉石s, and the 天文学者s argued that they give a reasonably 正確な 予測 for the 行為 of the real ones.?

'Therefore, 予定 to the 軌道 crossings happening in the long-称する，呼ぶ／期間／用語 進化, it is possible that some of the 玉石s will 衝撃 火星 in the 未来,' they 結論するd.

This could happen within 6,000 years - かもしれない 干渉するing with a 未来 human 植民地 on 火星.?

全体にわたる, though, the DART 使節団 has been considered a success, though.

For the first time in history, humans had 故意に changed the movement of a celestial 反対する.?

Dimorphos was not on a 衝突／不一致 course with Earth, but as a two-asteroid system it 供給するd a unique 適切な時期 to 跡をつける changes to a small asteroid's 軌道 around a large one.

That 実験（する） was proof that it is possible to knock asteroids off their course to keep them from wreaking 破壊 upon the Earth.

If a 殺し屋 asteroid 脅すs humanity in the 未来, this means that people should be able to コースを変える its path and 避ける 災害 - they just may want to 計画（する） for where the 破片 will go.

They published their findings on arXiv.org, the physics community's pre-print paper server.?
