What is inside Mars(火星)? Perhaps I may give you the answer in the near future. I am InSight(洞察号).I am a spacecraft. On Nov 27,I arrived on Mara. In fact, I am the eighth spacecraft in my family to successfully land on Mars. But I'm the first to study the things inside it.

What do I look like? I have an arm, It is 1.8 metres long. At work, if I need to move the things from my body to the ground, the arm helps me. On my arm, I have my single eye. You are right-it's a camera. I can use it to take pictures of Mars. As for navigation(导航),I will be led to the right place because scientists on the Earth keep telling me about directions. With three legs, I can stand well. And look at my two big “wings". Actually the get lots of power from the sun to make me work.

For the next 24 months-about one Martian year, I will stay on this red planet. Unlike brothers or sisters, I don't move a lot when I'm working on Mars. I will Just stay at one place use my heat probe(探热仪)to explore nearly 5 meters deep inside Mars. This way, I can get a lot of information about the inside without damaging the planet. Then I will send the information back to Earth. This may help scientists find out how Mars started.

Scott Sheppard was a member of the team that made the latest discoveries. The new moons were found using telescopes (望远镜) in Hawaii and Chile. Sheppard said, “I hope we can take clear photos of one of these moons in the near future to better understand it.”

Jupiter’s newly discovered moons are between one and three kilometers in size. They have not yet been named, as half of them are too small — less than 1.5 kilometers—to own a name.

Sheppard has already taken part in 70 moon discoveries for Jupiter. He also discovered moons going around Saturn (土星). Saturn had been the planet with the most moons until the most recent announcement. Saturn held the top position since 2019 when Sheppard’s team discovered 20 more moons. Saturn now is known to have 83 moons. Before that, Jupiter was the solar system’s leader with 79 moons.

Sheppard expects to keep adding moons to both Jupiter and Saturn in the future. Uranus and Neptune also have many small moons. But they are much farther from Earth. So discovering new moons around those planets is more difficult.

This year, the European Space Agency has sent a spaceship to explore Jupiter. The spaceship, called JUICE, took off in April. The task is to make further research on Jupiter and its three large moons.

【推荐2】About 20 years ago, Nissan introduced the world’s first “talking car”. Actually, it was just a recorded voice and it wouldn’t stop telling you to close the door until you really heard and did it.

Times have changed and the talking car of the near future is a car that you can talk to, rather than a car that talks to you. You’ll be able to control your radio by giving voice orders. And you can get traffic reports or directions, and send or receive emails in the talking car. To do all these, you needn’t push a button at all.

This is good news for those who spend more and more of their lives in their cars. In fact, the new type of cars will be more like offices on wheels because it has computers, wireless Internet and satellite radio inside. Companies are hoping that time wasted in traffic could be put to better use. If workers are able to check their emails, faxes, and meeting time on the way to work, they can spend more time at the offices doing more important tasks.

Microsoft, of course, is hoping that every one of those mobile offices will use Windows. “It’s a great goal,” says Dick Brass, VP of Microsoft’s automotive division (汽车分部). “But we’d like to have one of our operating systems in every car on earth.” There are already 650 million cars in the world, and every year about 50 million new cars roll off the production lines. If Brass’ wish came true, cars could become a bigger business for Microsoft than computers.

Hangzhou hosts the 19th Asian Games from September 23rd to October 8th, 2023.     1    

The place for the tennis finals is sometimes called the “Small Lotus (莲花)”. On the top of the stadium, there are eight “petals” (花瓣).     2     They can open and close freely. It takes 15 minutes for each petal to open and close. It’s built this way for different kinds of weather.

What if there’s an accident during the game and the athletes (运动员) need first aid? Drones (无人机) can be used to send things over.     3    

    4     In the kitchen of the athletes’ village in Hangzhou, there is a special system that can tell people’s faces. If a “stranger” enters the kitchen, an alarm will go off.

    5     Augmented reality (AR) is here to help. There’s a mini-program called the Hangzhou Asian Games AR service. You can simply turn on your phone’s camera, and it will see where you are and then show you the way.

A lot of people love to keep fish as pets because fish have beautiful shapes and colors. It is a great joy to watch them swimming in the tank (鱼缸).

Fish need a big tank, and you must fill in the tank with enough (充分的) water. There are many ways to keep water clean. First, you can put in some water plants. They can help make clean water. Then a few snails in the tank are a good idea. Snails move slowly with a “house” on their backs. They make great cleaners. Finally, we must change the water in time.

There are many kinds of fish food that you can get in pet shops. Most are ready for all kinds of fish. You should give your fish food once (一次) a day only. Remember, don’t give them too much. Just give them as much as they can eat in about fifteen minutes. This will keep them healthy.

【推荐2】Electricity is all around us. It’s in the computer you are using, it’s in the ground under your feet, and even it’s in your body. And you can’t live without electricity. How important the electricity is!

Without electricity, you wouldn’t be reading this article right now. It’s not because it’s not bright enough without electricity. It’s because your brain wouldn’t work.

Every move of your body needs the help of electricity. The nervous system (神经系统) sends electrical signals (信号) to your brain first, and then your brain sends them to your body. These signals don’t flow along a wire. They jump from one cell (细胞) to the next until they get to their final place. Then you can move as you want.

With so much electricity jumping around, it may seem like the body is a great power station. You may want to know if you have enough power to turn on TV. Well, your body can just make a little electricity. So stop dreaming. You are not a real power station.

【推荐1】Wukong, Tiangong, Tianwen…Do you know where the names of Chinese space programs come from?

Wukong, the Dark Matter Particle Explorer satellite（暗物质粒子探测卫星）, is named after Chinese superhero Monkey King. According to Journey to the West, Monkey King has a pair of sharp eyes which can tell the difference between good and evil. The Wukong satellite is just as sharp-eyed as Monkey King to help scientists search for dark matter in space.

The name of the space station, Tiangong, means “Heavenly Palace”. In Chinese myths, this is the home of Tian Di. Now Tiangong Space Station is a home for Chinese astronauts in space. And China welcomes foreign astronauts to Tiangong so that they can work together.

Tianwen, China’s Mars missions（任务）, gets its name from the poem Tianwen by Qu Yuan. Qu Yuan is a well-known poet from ancient China. In Tianwen, he had the questions about the sky, stars, nature, myths and the real world, showing his hunger for truth. Perhaps the Tianwen missions will end up answering some of Qu Yuan’s questions.

If you look into more names of Chinese space programs, you will find that they all have beautiful meanings. We, the Chinese people, have a long-cherished（珍藏已久的）space dream. So the naming of Chinese space programs is taken very seriously.

【推荐3】On Nov 16, seven astronauts on the International Space Station (ISS) woke up to an alarm. A Russian missile (导弹) test had just blasted a satellite (卫星) into more than 1,500 pieces of space debris (碎片). Some got very close to the ISS.

NASA says space debris like this can travel at more than 28,000 km/h. That’s much faster than a bullet (about 3,500 km/h). Even a pea-sized piece of debris could “wipe out” a space station or kill an astronaut if he or she is doing a spacewalk, says Live Science.

Since the 1950s, humans have sent thousands of rockets and satellites into space. Many are still there, and we now face an ever-increasing risk of space junk.

In 2006, for example, National Geographic reported that a tiny piece of space junk hit the ISS, taking a chip out of a window. In June of this year, a piece of debris ran into one of the station’s robotic arms and left a hole. Scientists are trying different ways to handle the problem. One way is to use a huge net.

In 2018, the UK’s Surrey Space Center caught some space junk with a net in an experiment. It first found the debris, and then collected it with a net and a harpoon.

Another solution is to use robotic arms. ClearSpace 1, the European Space Agency’s mission (飞行任务) to clean space junk, is going to be sent into space in 2025. It will use robotic arms to catch debris. The mission plans to throw the debris into Earth’s atmosphere, where it will burn up as it falls because of intense friction.
