Almost five years ago, the Japanese space probe "Hayabusa 2" breaks into space. She should collect special samples from an asteriod. The mission has succeeded, in 2020 the probe will return to Earth and possibly provide new insights into the formation of the solar system.
The Japanese space probe "Hayabusa 2" has left the asteroid Ryugu after successful mission and made his way back to earth. It will be back in November or December 2020, the Japanese space agency Jaxa announced. "We are grateful to the asteroid Ryugu and frankly are sad to leave him," says project manager Yuichi Tsuda. Launched in December 2014 in Japan, "Hayabusa 2" reached its 250 million kilometer target in the space of nearly four years in the end of June 2018. She later landed on Ryugu and collected samples from the surface and for the first time from an area below the surface of an asteroid ein.Ursprüngen the solar system on the track The researchers wanted to with the mission, at which also the German Aerospace Center (DLR) participated in the campaign with the French space agency CNES Lander "Mascot", the origins of the solar system on the track. In February, the probe landed on Ryugu for the first time, collecting samples from the surface of the asteroid. In July, she started again. To get samples from below-surface areas, Ryugu was shot at with a kind of projectile. Scientists suggest that the material thrown up contains traces of the time when the solar system was formed some 4.6 billion years ago. It could contain organic molecules as well as water, according to the Jaxa. Such asteroids could have brought water to our planet when impacted on Earth. Learned from the mistakes of the first mission. All those involved in the mission are content and can not complain about what they have achieved, Project Manager Tsuda said. A predecessor model of "Hayabusa 2" had brought in 2010 for the first time soil samples of an asteroid to Earth. According to Tsuda, "Hayabusa 2" was initially able to move away from the asteroid at a speed of 10 centimeters per second, taking further pictures of the celestial body. Once the probe has reached a distance of 65 kilometers in a matter of days, escaping the asteroid's magnetism, it will test its ion propulsion, as the Jaxa announced. This will take until December 2nd. Only then will the probe pick up speed. The collected samples are contained in a capsule that will drop the probe over the earth when returned.
