Japan's auditor was sent to collect 300 million kilometer asteroid samples for clues about the origin of life and the solar system was declining successfully on Friday, says scientists.
Hayabusa2 touched briefly on the Ryugu asteroid, fired bullet into the surface to burn dust to collect and blow back to a holding site, officials from Agency Japan Aerospace Research (JAXA).
Live broadcasting of the control room showed dozens of JAXA staff monitoring data before the touchdown earlier before exploding to approval after having a signal from Hayabusa2 that it had landed.
"We made a successful exchange, including bullet fire" into the Ryugu asteroid, as Yuichi Tsuda news councilors, Hayabusa2 told them.
"We made an ideal exchange in the best conditions," he said.
The complicated procedure took less time than expected and seems to have gone without proof, says Hayabusa2 mission manager, Makoto Yoshikawa.
"I'm really proud now. She was very sorry for the moment that the excitement happened," he said.
He said that the bullet fusion-the first of three designed in this mission- will lead to a blink, or new discoveries, in planetary science. "
It is believed that the asteroid contains relatively large amounts of organic matter and water of about 4.6 billion years ago when the solar system was called.
During a later mission, Hayabusa2 will eventually be a "impairment" fire to throw material under the Ryugu surface, allowing the collection of "fresh" materials to be waived for thousands of winds and radiation winds.
Scientists hope that those samples will be able to answer some basic questions about life and the universe, including whether elements of space help to cause life on Earth.
Brian May gave her the best: "Hurray. Great success in a touchdown on Ryugu."
Shape of fluid
Communication with Hayabusa2 is sometimes broken as its antennae are not always referred to Earth and could take several days to confirm that the bullet is being fired to allow samples to be collected.
The mission has not been sailing completely clear and the scanner was originally installed last year.
But after surveys it was pushed back that the asteroid's picture was more rough than what it was supposed to start, enforcing JAXA to take more time to find a suitable landing site.
Hayabusa2 mission was launched, with a cost of around 30 billion yen ($ 270 million) in December 2014 and intends to return to the Earth with samples in 2020.
Photos of Ryugu – which means "Palace Palace" in Japanese and refers to a castle at the bottom of the sea in an ancient Japanese show show, a little asteroid shaped like a spinning top with a rough surface.
Hayabusa2 observes the asteroid surface with camera and sensing equipment but has also sent two small MINERVA-II mini robots as well as the French-German MASCOT robot to help surface observation.
Scientists have already received data from these crews that were used on the surface of the asteroid.
In terms of large fridge size, Hayabusa2 has solar and sequential panels to the first JAXA asteroid, Hayabusa-Japanese for falcon.
That search returned from a smaller asteroid, potato shaped in 2010 with dust samples despite various disadvantages during its seven year epic odyssey and is known as a scientific victory.
