"Ostrich 2" Japan landing the Nikkei Chinese Network "Dragon Palace" asteroid

The Japan Aerospace Agency (JAXA) released a message on February 22 that the "Ostrich 2" sensor had hit the asteroid "Palace Palace" about 300 million kilometers of Earth. It is said that many rocks have been scattered on the face of the Dragon Palace. The ostrich 2 landed in a narrow area with a radius of just 3 meters. Rock samples were taken for a few seconds. This is another challenge since the first generation of Japan of "ostriches" tried to remove asteroids first in 2005. Achieving very detailed landing, while showing Japan's technological strength, it also shows the presence of the world in Japan in the field of investigation asteroid.

The asteroid rock is a "time capsule" which preserves the remains of the solar system when it was born 4.6 billion years ago. "Ostrich 2" will challenge the landing again by summer 2019 and return to Earth by the end of 2020. The expectation of exploring the mystery of the universe's origin and the birth of life grows.

"Ostrich 2" started down for 6 hours in the morning on February 22, Japan time. During the final stage of the delay in the signage of the Earth, the camera and the automated automation campaign, and finally, it landed at 7:50 am on the 22nd.

"Ostrich 2" is delayed in communicating with the Earth before and after landing depending on the land. JAXA introduces a series of actions before and after landing based on a small amount of data returned by the sensor. By changing body speed, there is a "landing" collection.

JAXA also believes that "ostrich 2" has successfully collected rock samples and will eventually determine if it is successful after the recovery bin returns to the Earth.

"Ostrich 2" is the successive model of the first generation of ostriches that brought the "Kawagawa" asteroid back to Earth in 2010. It was launched in December 2014 by the Island Space Center Seed in Kagoshima Prefecture, Japan, and reached the vicinity of Dragon Palace in June 2018. It is estimated that the total cost of business until returning to the Earth is approximately 28.9 billion yen.

One of the purposes of detecting asteroids is to examine the question of the origin of mankind, "Where is life coming?"

Dragon Palace is about 900 meters of diameter and is believed to have been covered with rocks, which include organic material and water from a source of life. There is a presumption that asteroids that conflict with Earth cause substances such as an organic issue, which promotes the birth of life. There are many asteroids scattered between Mars and Jupiter. However, Palace Palace is between Mars and Earth. Rockets from Dalts and Dragon are easier to bring back to Earth. So the resort is "Palace Palace".

Japan is hoping to show the world's technological strength when exploring the moon, the Mars and the objects. According to the image of the camera and the position of the star, it is close to the remote asteroid and landing correctly. Experienced procedures and experience will be an advantage to Japan.

The National Aeronautics and Space Administration (NASA) sent the "OSIRIS-REx" asteroid search, known as the "American version of the ostrich," for the "Setting" asteroid. It is intended to collect rock samples in 2020 and return to Earth in 2023. It is said that the United States is very concerned about the "ostrich 2" situation.
