These small robots took the first images of an asteroid



To keep it short: two small robots, each as big as an orange, landed on an asteroid that circles millions of miles of the earth, to give us snapshots of the universe.

The journey to the asteroid Ryugu lasted three and a half years (he left the earth on December 3, 2014), and the journey was more than 3,200 million kilometers, 21 times the distance from the earth to the sun.

The Japanese Hayabusa2 space probe reached its orbit and dropped the pair of reconnaissance robots on the celestial body.

The operation marked several milestones: it was the first soft landing on an asteroid and the first deployment of scout robots in an environment with low gravity.

"It is also the first object in the world made by humans to examine movements on the surface of an asteroid," said the Japanese space agency JAXA, responsible for the operation.

The never seen

Space explorers (Rover-1A and Rover-1B) move with their jumps through the surface and can reach up to 15 meters and can stay in the air for up to 15 minutes.

The images that come from the Hayabusa 2 probe are sent by the explorers and show that an extraterrestrial landscape that is different from what people have ever seen.

"I can not find words to express how happy I am," he said. Yuichi Tsuda, project manager of Hayabusa2, in a statement just after the landing.

The research

The next step in the Hayabusa2 mission is to "bombard the surface" of the asteroid. The spacecraft fires a copper rocket that will "explode" on this sky rock.

This will create a special landing site for the ship to make short stops on the surface and collect material samples.

The Japanese company reported that the robbers They are in excellent condition. There they will study the rocky object for one and a half years and return to earth in December 2020.
