The Return of HAYABUSA2

      Last Sunday, I watched the live image of the return of HAYABUSA2, which is the space probe of JAXA. At about 2:29 a.m. , a fireball appeared and went through the sky of Woomera with thin tail. The light disappeared in short time, but it remains in my memory strongly. 

     HAYABUSA2 was launched in December third, 2014. It's purpose is to bring back the soil sample of minor planet called 1999JU3 (after the launch of HAYABUSA2, this asteroid was named Ryugu, come from a castle appeared in a Japanese folk tale). Ryugu is a kind of minor planets that is thought to contain some water or organic matter in it's soil. By researching these soil, we may be able to solve the mystery of how the solar system was formed and where the lives came from.

    HAYABUSA, the predecessor of HAYABUSA2, experienced a lot of difficulty in it's mission to bring back the soil from Itokawa. HAYABUSA2 could put the past lessons of HAYABUSA very well and it is still in very good condition. It proofed that Japan has wonderful technique of interstellar travel. 

     After released the capsule which stored the sample, HAYABUSA2 begin it's expansion mission to explore another minor planet called 1998KY26. It will cost 11 years to arrive there. I want to watch the journey of HAYABUSA2 in the future too.

     Today I listened to the English News Weekly Podcast. The title of the podcast is "Rugby World Cup 2019".      In this podcast,  the ENW team focus on the final of the world cup and what history was created there. In the world cup, South Africa defeated the England and won the third world title. The ENW went to the Yokohama International Stadium to watch the game. They found that there was an almost equal division between who supporting South Africa and who supporting England. The victory of the final made South Africa the second country that win three world cups. (The other is New Zealand.) It also created a new bit of history. Siya Kolisi, the 28-year old captain of the South Africa team became the first non-white to hoist the Webb Ellis Cup. This became a milestone for the history of South Africa that had been suffered from the racism.      When this World Cup was held, I was the third grade student of the high school. I clearly r...

I was very busy last week.

     I was very busy last week.     First, I have to prepare for midterm tests of Inorganic Chemistry and Biochemistry. Especially, Inorganic Chemistry is very difficult to understand because it contains the theory of Physics. I'm not good at Physics so I have to review my notebook many times. There are also many things to remember to solve the questions of Biochemistry. I hope I could done my best at these tests.     Second, I have many homework. For example, the reports of Chemical experiment and Biological experiment, English terms of Biology, the homework of Programing and so on. Fortunately, I could finish all of them by the dead line but they made me very tired.     This week, I can relax than last week so I want to sleep a lot, play games, and join the club activity.
