①A Long March 2F rocket carrying the Shenzhou-18 spacecraft with three astronauts was successfully sent into space on April 25th from the Jiuquan Satellite Launch (发射) Center in Northwest China.
②The astronauts are Ye Guangfu, Li Cong and Li Guangsu, with Ye as the leader. It is Ye’s second time to go to space within 3 years. And this is Li Cong and Li Guangsu’s first space flight.
③This launch has a lot of breakthroughs (突破). First of all, launching in April is really challenging. April is famous for being very windy and sandy in the center. So, experts carefully planned the best time to launch according to the April wind speed data from the last 10 years. Secondly, there have been greater technological developments in both the spacecraft and the rocket, resulting in higher safety. Another big change worth mentioning is the new battery (电池) for the spacecraft. It is lighter and can work longer.
④The three astronauts will carry out many tasks during their stay. More than 90 experiments (实验) covering areas such as materials science, life science and medicine will be carried out in space.
⑤A very special task is to raise Zebrafish in space. They will create a simple ecosystem to study how the space environment affects their growth and system balance. If the experiment succeeds, it will be a significant breakthrough to keep vertebrates (脊椎动物) in China’s space program.
⑥Moreover, they will also learn how plants change and get used to the environment by doing the first-ever stem cell (干细胞) study in space. This will help to choose suitable vegetables for space farming.
⑦Besides these experiments, the astronauts will do two or three space walks and six cargo deliveries. And they will further keep the safety of space station.
⑧Exploring space is not just a dream for our country. We are making new achievements continuously, showing the world that China is becoming stronger and stronger. And we are sure the Shenzhou-18 crew will do well, although the tasks have become more complicated and harder.

For thousands of years, humans have explored (探索) the Earth. Nowadays, we are exploring space. Astronomers (天文学家) are the modern day explorers. Now, many astronomers are looking for new planets and new places for humans to live in the future. But where do astronomers start looking?
First of all, astronomers look for a star. That's because our own Earth moves around a star (the Sun).More importantly, it is the correct distance (距离) from the Sun for heat and light. So when astronomers have found the star, they look at the planets around it. In recent years, astronomers have found nearly 400 new planets with stars. However, many of these planets are either too near the star or too far away.
However, if the planet is in a good position, astronomers look for three key things: water, air and rock. Water is important because all life needs water. Humans can drink it and also grow plants with water. And plants produce air for humans to breathe and food to eat. Rock on a planet is also important. That’s because there is often water under the rock.
After many years of scrutinizing, astronomers have found a planet that is similar to the Earth. It’s Gliese 581g and it’s near a star. The astronomers think it has water and rock and the average (平均) temperature is between－31°C and－12°C. That’s cold, but not colder than Antarctica or the Arctic Circle, for example. Gliese 581g is bigger than the Earth. A year on Gliese 581g is only 37 Earth days instead of 365.But astronomers do not think these are big differences and some of them think Gliese 581g will be a new Earth. However, Gliese 581g is twenty light years from the Earth.
