The Crater Search Operation (Post-SCI): (CRA2)

The Small Carry-on Impactor (SCI) operation successfully took place on April 5. A 2kg copper mass was fired using the collision apparatus to collide with Ryugu. The gravel released from the surface of Ryugu was photographed by the deployable camera, DCAM3. However, the images from DCAM3 do not show how Ryugu's surface has been altered by the impact. Hayabusa2 will therefore descend and make observations in the vicinity of the SCI collision area.

The CRA2 operation will take place from April 23 – 25, 2019, with preparation for the descent beginning on April 23, the descent itself starting on April 24 and the observations at the lowest altitude (about 1.7km) on April 25. The spacecraft will then rise on April 25. Figure 1 shows the location of the observations. The area to be observed is the same as that observed on March 22 in the Crater Search Operation (Pre-SCI) (CRA1).

The schedule for the CRA2 operation is shown in Figure 2. The spacecraft begins its descent at a speed of 0.4 m/s on April 24 at 16:42 JST (all times are onboard times). The speed is reduced to 0.1 m/s on April 25 at around 03:02. The descent will then continue and reach the lowest altitude (at about 1.7 km) at round 11:16 and continue to observe at this altitude for a while. The spacecraft will begin to rise at 12:53 and return to the home position. Please note that these are the planned times and the actual operation time may vary.

小惑星探査機「はやぶさ2」衝突装置運用の成功について

平成31年4月25日

国立研究開発法人宇宙航空研究開発機構

 国立研究開発法人宇宙航空研究開発機構(JAXA)は、平成31(2019)年4月5日に小惑星探査機「はやぶさ2」に搭載した衝突装置(SCI: Small Carry-on Impactor)を小惑星Ryugu(リュウグウ)に向けて分離し、作動させる運用を行いました。
 「はやぶさ2」に搭載している望遠の光学航法カメラ(ONC-T)の観測画像を確認した結果、衝突装置によりクレーターが生成されたと判断しましたのでお知らせします。
 現在、探査機の状態は正常です。

Об успешном применении зондом-исследователем астероидов "Сокол-2" системы столкновения

25 апреля 2019 г.

Японское агентство аэрокосмических исследований

Японское агентство аэрокосмических исследований (JAXA) сообщает, что 5 апреля 2019 года
зонд-исследователь астероидов "Сокол-2" отделил устройство столкновения (SCI: Small Carry-on Impactor), установленное на зонде, в направлении астероида Рюгю для проведения ударного воздействия.

В результате изучения изображения, полученного оптической навигационной камерой (ONC-T), установленной на «Соколе-2», определено, что воздействие устройства столкновения породило кратер.

В настоящее время состояние космического зонда нормальное.


Дата съёмки
Изображение слева 22 марта 2019 г.

(Дата съёмки по японскому времени)

Изображение было получено с помощью оптической навигационной камеры (ONC-T), установленной на "Соколе-2".
При сравнении левого и правого изображений искусственный кратер, созданный устройством столкновения, был обнаружен в области, обведенной пунктирной линией.
Проводится анализ размера и глубины кратера.

В Японии подтвердили создание искусственного кратера на астероиде Рюгу

Операция по созданию кратера была проведена 5 апреля

ТОКИО, 25 апреля. /ТАСС/. Японское агентство аэрокосмических исследований (JAXA) смогло удостовериться в том, что его зонд "Хаябуса-2" ("Сокол-2") в начале апреля успешно создал на поверхности отдаленного астероида Рюгу (в переводе с японского - "дворец дракона") искусственный кратер. Об этом в четверг объявила JAXA.

Операция по созданию на поверхности Рюгу искусственного кратера была проведена JAXA 5 апреля. Зонд "Хаябуса-2" взорвал у поверхности астероида специальный блок, который выстрелил в поверхность Рюгу двухкилограммовым медным снарядом. В результате столкновения на астероиде образовался обширный искусственный кратер округлой формы. Подчеркивается, что подобный кратер на поверхности астероида был создан впервые.

[CRA2] The exact size and shape of the artificial crater will be examined in detail in the future, but we can see that terrain of an area about 20m wide has changed. We did not expect such a big alternation so a lively debate has been initiated in the project!

Successful Operation of Asteroid Explorer Hayabusa2's SCI

April 25, 2019 (JST)

National Research and Development Agency
Japan Aerospace Exploration Agency (JAXA)

Japan Aerospace Exploration Agency (JAXA) separated the SCI (Small Carry-on Impactor), which had been onboard the asteroid explorer Hayabusa2, on April 5, 2019, for deployment to Ryugu, and then put the SCI into operation.

As a result of checking the images captured by the Optical Navigation Camera - Telescopic (ONC-T) onboard the asteroid explorer Hayabusa2, we have concluded that a crater was created by the SCI.

Hayabusa2 is operating normally.


Images taken by the ONC-T:
Left image: Taken on March 22, 2019
Right image: Taken on April 25, 2019
(Onboard date, JST)

These images were captured by the Optical Navigation Camera - Telescopic onboard Hayabusa2. By comparing the two images, we have confirmed that an artificial crater was created in the area surrounded by dotted lines. The size and depth of the crater are now under analysis.
