They will also measure the surface temperature ahead of Hayabusa2's own landing late next month. This celestial body is now under the gun of two Japanese mini-Rovers. The rovers move by "hopping" up to 15 meters at a time because the extremely weak gravity on the asteroid makes rolling hard.
Since Hayabusa 2 previously rendezvoused with the space rock prior this mid-year, the test has been consistently snapping photos of the objective.
The two small "rovers", which were despatched from the Hayabusa-2 spacecraft on Friday, will move around the 1km-wide space rock known as Ryugu.
The Ryugu asteroid is a small diamond-shaped c-type asteroid which looks desolated n its surface, however, it is believed to have a trove of the treasure of primitive organic substances as well as minerals and much more. Communication with the two landers stopped of touchdown. And thus we are left with a suspenseful situation. After that, Hayabusa2 got back up, at 20 km distance. The innovative mission will spend the rest of this year and almost all of 2019 at Ryugu.
The agency called JAXA, confirmed the successful landing Saturday and posted photos taken by the little landers online. It will see the spacecraft deploy an impactor, which in turn will fire a 10-millimeter projectile with a mass of 5 grams into the surface. It arrived at Ryugu on June 27, 2018 and is scheduled to depart from the asteroid in December 2019 in order to return to our planet in December 2020. They have been created to "hop" along the surface of the asteroid as its low gravity would complicate the traditional way of robotic explorers rolling on wheels or tracks.
"The good news made me so happy", Hayabusa2 project spokesperson Takashi Kubota said in a statement on the mission website.
