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.
