Space junk is a danger to the satellites and may hurt astronauts. There are tens of millions of pieces of rubbish in space. Some of the pieces are from passing comets, but most of them are from large broken satellites and rockets after they stopped working.
Though satellite technology offers some advantages to people, the increasing use of it could make large areas of Earth’s orbit into bad condition. The space closely around our planet is becoming increasingly crowded with over 9,000 satellites in orbit today, and the Eastern Southern Observatory (ESO) shows that this number may grow to 75,000 by 2030.
As Space.com reported in October 2022, the International Space Station (ISS) had to think about how to keep clear of a piece of space junk from a broken Russian satellite in 2021. In November 2021, astronauts in the ISS had to stay inside their spaceship when the space station passed close to space junk.
NASA scientists have called for an agreement to make sure “space junk” doesn’t make the activities in Earth’s orbit into trouble and they are working on it. “Satellites are important to the people and Earth itself. However, using too much space will put our planet into a dangerous situation,” said Melissa Quinn, Head of Space port Cornwall. “I hope all countries need to pay attention, to understand the importance of the next step, and to work together, to keep the problem under control.”

Can anyone be an astronaut?
Of course not. You don’t have to have a science degree but most astronauts do. Most of them are pilots too. Life in a spaceship is hard so you must have a healthy body and mind. You need to be easy going, patient, and helpful to spend so much time in a small space with other people.
What’s the training like?
People have to train for a year to learn how to stay healthy and safe. They practise space walking and living in zero gravity. They train in difficult conditions to learn how to solve problems and to work in a team. Everyday tasks like eating, washing and sleeping can be difficult in a spaceship. There is no running water so you have to wash with wet tissues; it’s hard to enjoy the dry food that astronauts have to eat. And to sleep you must cover your eyes because the sun rises every 90 minutes on the International Space Station. You also have to tie yourself to something so you don’t fly away!
What health problems do astronauts have?
Life in zero gravity causes changes to our bodies. Bones and muscles(肌肉) become thin and weak so you must do a lot of exercise in space to stay fit and to help the heart move blood around your body. Astronauts often get backache because people grow in space-up to 8 centimeters! It’s also common to have headaches and to feel sick, especially at the beginning. You must have vitamins to take the place of fresh fruit and vegetables. But you don’t have to put on sun cream because space suits protect your skin.
Are you still interested?
So now you know. If you want to go to space, study hard, learn to fly and take care of your body and mind.

【推荐3】While long-distance travel is not a top choice during the COVID-19 pandemic(新冠病毒大流行), camping has risen as a new travel trend (趋势) for people living in Chinese cities.
A report by online travel website Tongcheng Travel showed that during the recent May Day holiday, camping-related(与露营相关的) searches increased by 117 percent compared with April. Forests and islands were the two most popular location (地点) types.
Ji Nan, 31, from Zhejiang, went camping with her friends in the mountains during the holiday. “It was relaxing,” Ji told China Daily. She said camping is a good way to get closer to nature and enjoy outdoor activities.
The growing popularity has also fueled(刺激) the demand for camping equipment(装备), such as tents, outdoor tables and chairs, picnic mats(垫子) and sleeping bags. Trip, an online travel agency, said page views(网页浏览) for their camping goods on the first day of the May Day holiday rose by 90 percent over the previous (之前的) week, reported Global Times.
However, the demand for campsites is greater than the available supply(供给). “Everywhere is full and there is a tent every several meters,” a tourist surnamed Yun, from Beijing, told Global Times.
Besides, camping isn’t always good for the local environment. In Beijing’s Shuangfeng campsite, some of the land is barren(荒芜的) from too much foot traffic. Trash, like bamboo barbecue(烧烤) sticks and disposable plates (—次性餐盘), could be seen everywhere, reported Xinhua.

SCIENCE Xinhua May 30, 2020 Space X rocket launching two NASA astronauts to space successfully WASHIONGTON, May 30 (Xinhua)-U. S. Private space company Space X launched two astronauts into orbit(轨道)on Saturday. Later, Space X confirmed(证实)successful deployment(部署)of the rocket. The Space X rocket designed and built by Elon Musk’s Space X company has lifted off, sending Hurley and fellow astronaut Bob Behnken on a history-making flight to the International Space Station after launching hundreds of satellites to the space. Earlier this week, the flight into orbit was called off(取消)with 16 minutes to go in the countdown(倒计时)because of the danger of lightning. Lift off was rescheduled for Saturday at 3: 22 p. m. After earlier concerns about the weather, it appeared by 3 p. m. that conditions were favorable(有利的)for launching. The spacecraft took off on Saturday afternoon from the same launch pad at Cape Canavral, Florida, that was used during the Apollo missions to the moon a half-century ago. The spacecraft was originally set to launch on Wednesday afternoon for International Space Station, leading in a new period in commercial 9(商业的)spaceflight and putting NASA back in the business of launching astronauts from U. S. for the first time in nearly ten years. This launch was also the first one from a private vehicle(运载工具), Elon Musk’s Falcon 9 rocket(猎鹰九号火箭). Ever since the space shuttle(航天飞机)was retired in 2011, NASA has depended on Russian rocket to carry astronauts to and from the space station. Hurley and Behnken will spend about 19 hours in orbit before they catch up to the space station where they will be for a time between one and three months. |
