Check out close-up views of asteroid (plus a movie) from Japan’s Hayabusa 2 mission
This image of the asteroid Ryugo was captured by the Hayabusa 2 probe’s ONC-T camera at an altitude of about 64 meters (210 feet). Image was taken on Sept. 21.

The scientists and engineers behind Japan’s Hayabusa 2 mission made history last week when the mission’s mothership dropped two mini-rovers onto the surface of the asteroid Ryugu, 180 million miles from Earth, but they’re not resting on their laurels.
The first rovers to hop around an asteroid’s surface have continued to send back pictures of their travels — and so has the main spacecraft, which is keeping watch dozens of miles above them.
One of the pictures shows a high-resolution view of Ryugu’s surface from above, highlighted by a big boulder’s sharp shadow. The image was captured by the main spacecraft’s telescopic optical navigation camera, or ONC-T, as it closed in on Ryugu for the rover drop on Sept. 21.
“This is the highest-resolution photograph obtained of the surface of Ryugu,” the science team says. Two farther-away pictures from Hayabusa 2’s archive show the wide-angle context for the scene:

The spacecraft also has been relaying back more pictures from the mini-rovers. Here’s a six-pack of tweeted highlights, starting with a 15-frame movie assembled from Rover-1B’s snapshots.
Rover-1B succeeded in shooting a movie on Ryugu’s surface! The movie has 15 frames captured on September 23, 2018 from 10:34 – 11:48 JST. Enjoy ‘standing’ on the surface of this asteroid! [6/6] pic.twitter.com/57avmjvdVa

Our MINERVA-II1 rovers have sent back more images from the surface of Ryugu! Let’s take a look at these images in detail.

There’s still more drama ahead: Hayabusa 2 is due to drop a bigger rover known as MASCOT to Ryugu’s surface on Oct. 3, followed by rounds of surface sampling and the release of yet another mini-rover next year. If all goes well, Hayabusa 2 will head back toward Earth and drop off its precious samples of asteroid soil in late 2020.
