During this phase of the mission, the spacecraft will reportedly detonate explosives on the asteroid to create a small crater so the rovers can take further samples. Hayabusa2 flew to within just 60 metres of the asteroid's surface, before successfully deploying two small robots.
Japan now has two rovers on an asteroid 280 million kilometres from Earth, and they've started sending back the first pictures of life on a very lonely rock. In Figure 1, although the image is blurred due to the rover rotating, you can clearly see the body of Hayabusa2 and the paddle of the solar cells.
Hayabusa2 arrived at Ryugu (280 million kilometers from Earth) on June 27 after its launch on December 3, 2014.
B will explore the giant asteroid. It was taken on Ryugu's surface during a hop.
Weighing only 3.3 kg, the MINERVA-II1 is a compact rover and consists of two more rovers - Rover-1A and Rover-1B.
Besides this historic asteroid landing, JAXA's mission is the closest ever to asteroid mining.
The agency tried but failed in 2005 to land a rover on another asteroid in a similar mission. "This is just a real charm of deep space exploration", said Takashi Kubota, a spokesman for the space agency.
Yesterday, JAXA said in a tweet that it had lost communication with the rovers after they dropped from the spacecraft.
Yuichi Tsuda, Hayabusa2 project manager said: 'I can not find words to express how happy I am that we were able to realise mobile exploration on the surface of an asteroid.

Japan's space agency has managed to surpass ESA's achievement of landing a craft on an asteroid by landing two rovers on another.
The rovers maneuver by hopping and will send back data about the asteroid using cameras and instruments, including temperature and optical sensors.
The mission objective is to send data and collect samples and bring them back by 2020.
The spacecraft is set to release a German-French lander called MASCOT carrying four observation devices in early October and a bigger rover called Minerva-II-2 next year.
