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.
