By September 22, images and data confirmed that both rovers had landed on Ryugu and that at least one was hopping and moving. We published a press release on September 22, releasing the situation of MINERVA-II1 and the acquired images. (3/4)

On September 21 after 13:00 JST, the two MINERVA-II1 rovers, Rover-1A & Rover-1B, separated from the spacecraft. The spacecraft then rose and returned to the home position at around 15:00 JST on September 22. After separation, we attempted communication with MINERVA-II1. (2/4)

"I cannot find words to express how happy I am..." Y.T. The MINERVA-II1 rovers have successfully landed on asteroid Ryugu, snapped photos & taken the first successful hop! Have a read about this world first and hear the comments from our Project Members.

This dynamic photo was captured by Rover-1A on September 22 at around 11:44 JST. It was taken on Ryugu's surface during a hop. The left-half is the surface of Ryugu, while the white region on the right is due to sunlight. (Hayabusa2 Project)

Photo taken by Rover-1B on Sept 21 at ~13:07 JST. It was captured just after separation from the spacecraft. Ryugu's surface is in the lower right. The misty top left region is due to the reflection of sunlight. 1B seems to rotate slowly after separation, minimising image blur.

This is a picture from MINERVA-II1. The color photo was captured by Rover-1A on September 21 around 13:08 JST, immediately after separation from the spacecraft. Hayabusa2 is top and Ryugu's surface is below. The image is blurred because the rover is spinning.

We are sorry we have kept you waiting! MINERVA-II1 consists of two rovers, 1a & 1b. Both rovers are confirmed to have landed on the surface of Ryugu. They are in good condition and have transmitted photos & data. We also confirmed they are moving on the surface.

[MINERVA-II1] September 22 at 15:00 JST. We have confirmed Hayabusa2 has returned to the home position (altitude about 20km) as planned & the spacecraft’s condition is nominal. This completes the operation for the MINERVA-II1 separation. Thank you for your support from everyone!

[MINERVA-II1] Communication with MINERVA-II1 has currently stopped. This is probably due to the rotation to Ryugu, and MINERVA-II1 is now on the far side of the asteroid. We are currently working to confirm if there are images capturing the MINERVA-II1 landing.
