Hayabusa-2: Fragments of an asteroid found in a space capsul |

Scientists were greeted by sightings of rock and black earth from the asteroid after opening a capsule returning from space last week.It is the first sample of important materials sent to Earth from space rocks and Japan's Hayabusa-2 spacecraft took over last year.Researchers began opening the capsule on Monday (GMT) in Sagamihara, Japan.The material is drawn from an asteroid called Ryugu.Hayabusa-2 arrived at the object in June 2018.It is believed to be one of the building blocks left over from the solar system's formation.
Scientists from xo Japan's Aerospace Administration (Jaxa) at Sagamihara have opened one of three sampling rooms inside the capsule.Hopefully there will be rock and earth particles from Hayabusa-2's first touchdown on the asteroid in 2019.The spacecraft grabs the material by firing a tantalum metal bullet into the surface and letting the debris float up in the collection tube. Under low gravity Scientists were excited to see a black seed from an asteroid stranded at the entrance to the sample detector. (Material storage) on Monday, and they weren't disappointed when they opened it: Inside were materials ranging in size from pebbles to tiny dust.Dr Yuichi Tsuda, Hayabusa-2 project manager at Jaxa, said at the press conference: “We confirmed that the capsule contained a large amount of [material] collected from Ryugu.He added: “The sample of the asteroid's material we were dreaming of now is in our hands.
'Pure material'
However, this is only one of the three chambers inside the capsule, the Sample Room B should be empty, but the C chamber is thought to hold material collected from beneath Ryugu's surface.Scientists wanted to collect ancient material from Ryugu that had not been altered by exposure to the space environment - including radiation - for aeons.To do this, they had to use explosive charges to drive the copper projectile. Enter the surface of the asteroid A 20-meter-wide crater in Ryugu allows Hayabusa-2 to descend and capture material ejected from within the crater and deposited in the C chamber.
Scientists should open this room as scheduled.Jaxa also announced that the gas collected from the capsule comes from the asteroid.It is likely to be released by soil collected from Ryugu and is the world's first gas sample returned from space. Asteroids are the building materials left over from the formation of the solar system. They are made up of the same thing that made the rocky world like the world. But they still roam freely rather than on the planet Ryugu belong to a primeval space rock class known as the C-type (or carbonaceous) asteroid.
In the early solar system, the object was able to deliver a great deal of water from Earth, along with the ingredients needed to start life.When the spacecraft reached its target in 2018, scientists were amazed by the Dark Ryugu. The unexpected color even forced the controller to adjust the laser altitude sensor used as the spacecraft approached the asteroid's surface.The Hayabusa-2 sample capsule returned to Earth on Saturday, December 5, skydiving safely in the Australian desert near Woomera. |

Really I appreciate the effort you made to share the knowledge. The topic here I found was really effective to the topic which I was researching for a long time.
