The asteroid's journey to the Australian desert, Hayabusa2, continues
Find the asteroid visitor in the desert, which tells the origin of the solar system and predicts the future of The Earth

The capsule was released by Japan's Hayabusa2 asteroid probe, which at six years into its mission to release markers at the asteroid Ryugu.
The gifts brought back from the recycling chamber are particularly special, magical things that humans have only touched once.
This is the second time in human history that an asteroid sample has been obtained, and the sample, which is on its way to a laboratory in Japan, is on a new journey to change the scientific understanding of these space rocks, and it will also help us learn more about the solar system.
On February 21, 2019, Hayabusa2 landed on the asteroid Ryugu, ending five years of space drift. (Hayabusa2 arrived near Ryugu in June 2018, and before its final landing, it spent more than a year orbiting it, collecting observational data and images from Ryugu.) )

The probe took some samples from the asteroid Ryugu before returning to Earth. After Hayabusa2 arrived on Earth, it threw a 40-centimeter-square recovery capsule toward Earth on Friday night. The recovery capsule landed in the Woomera Military Exclusion Zone in southern Australia – an area operated by the Royal Australian Air Force for military and civilian research (interestingly, this area is not completely off-limits, you just need to have a tourist permit).
How to find the recovery chamber – The search team searched for the recovery chamber inland Australia through radio waves emitted by the radio signal device on the recovery chamber.
The Japan Aerospace Exploration Agency (JAXA) has set up five receiving antennas around the projected landing site covering a range of 38 square miles to help find signals from the recovery chamber, and JAXA has also deployed a helicopter with a signal receiver over it.
This is japan's second asteroid sampling mission, after Hayabusa brought back to Earth samples from asteroid Itokawa on June 13, 2010.

Why study asteroids – Asteroids and solar system planets are formed from the same material, and they may provide clues as to how water and other living matter reached Earth and originated from life.
Much of what we know about asteroids comes from meteorites, and when their parent comets and asteroids pass by Earth, they rain down on Earth. But the material in meteorites can change a lot due to the earth's atmosphere, water or weather. As a result, that small sample taken from an asteroid in space could provide scientists with pure, primordial material from the time the solar system was infancy billions of years ago.
Another reason scientists study asteroids is their potentially threatening nature.

Ryugu is a potentially threatening asteroid near Earth , about 0.6 miles ( or about 965 meters ) in diameter. It orbits the Sun in an elliptical orbit on a 16-month cycle, passing right through the orbits of Earth and Mars.
NASA keeps a close eye on asteroids orbiting the solar system, fearing that an asteroid will head in the direction of Earth and collide with Earth.

Follow-up – After releasing samples to Earth, Hayabusa2 has made its way to its next stop, the smaller asteroid numbered 1998KY26. Hayabusa2 expects to make no-land exploration of the globular asteroid in 2031.
Meanwhile, NASA's Osiris-Rex probe is expected to take samples of the asteroid Bennu in October, with the two nasas exchanging space rocks they have collected. NASA will get a portion of samples from the asteroid Ryugu from JAXA and share samples from Bennu after the probe arrives on Earth in March 2021.
