A Japanese spacecraft successfully blasted a crater Ryugu, the mission confirmed today (April 25), releasing an animation showing how impact changed the asteroid's surface.
The visual confirmation of the maneuver's effects mark another major milestone in the Hayabusa2 mission that Japan Aerospace Exploration Agency (JAXA) feels to explore Ryugu.
"The exact size and shape of the artificial crater will be examined in detail in the future, but we can see that [60 feet] 20 m[eters] wide has changed, " JAXA wrote in an update on Twitter. "We did not expect such a big alternation so a lively debate has been initiated in the project!"

So far, JAXA has released only before-and-after images of where the spacecraft has been created. The 'after' picture was captured during a recent excursion that feels Hayabusa2 to hover near the surface of Ryugu. The main spacecraft had ducked behind the asteroid flying debris.
The JAXA team did not want to leave their mark on another solar system. The artificial crater operation has scientific value as well; Ryugu's weathered surface.
Now that JAXA has confirmed the operation in a crater, the scientific work can begin. That may include sucking up a sample of that deeper rock, which would join sample collected earlier this year from another site on Ryugu.
Hayabusa2 will remain asteroid until the end of this year, when the spacecraft turns towards Earth with its precious cargo of space rock samples on board.
