The 60-foot-tall rocket took off in West Texas, sending a group of six people into space and giving them a few minutes of weightlessness before they landed by parachute (降落伞).
Most of the passengers paid a secret sum of money for their seats. But Katya Echazarreta, an engineer and science communicator, was selected by a nonprofit organization to join this travel from a pool of thousands of applicants (申请⼈). The organization’s goal is to send great leaders into space and allow them to experience the overview effect, which was reported by astronauts who say that viewing the Earth from space gives them a great change in their view.
“Looking down, you see everyone is down there, all of our past, all of our difficulties, everything — everything is there,” Echazarreta said. “When I came back down, it just completely strengthened my wish to continue enabling people of different backgrounds to go into space and do whatever they want to do.”
Echazarreta is the first Mexican-born woman to travel into space. She moved to the United States with her family at the age of seven. She recalled (回忆说) that she felt uncertain in a new place where she didn’t speak the language and that a teacher warned her she might have to repeat a grade. “It just really fueled me and after that, I just studied harder,” Echazarreta said. Later she was the main breadwinner in her family. She had sometimes up to four jobs at the same time, just to try to successfully graduate from college.
She worked in NASA before and didn’t see other female engineers like her, which inspired her to popularize science among the public. These days, Echazarreta is studying for her master’s degree in engineering at Johns Hopkins University. She also has a following of more than 330,000 fans on TikTok, and hosts a science-focused YouTube series.

【推荐2】I had never really liked reading, and I thought it was a waste of time. But when my teacher told me to go to the library and find a book, I looked for one that I was actually interested in. I love basketball, so I picked out a basketball book which was called Hoops by Walter Dean Myers. It is an amazing story about a high school ball player named Lonnie. He is a great basketball player, and dreams of playing basketball in college someday, and of course in the National Basketball Association (NBA).
Lonnie lives in Harlem, NY, and is struggling through poverty and other problems. He doubts his new coach, Carl, and doesn’t think that he will be there for his new team. However, he soon realizes what the man has done in his past, and can completely connect with him. Carl soon makes a huge influence on Lonnie, but they face many challenges.
This book makes me think about how hard it would be to grow up in a rough city. I have realized that basketball is a great way to escape the struggles we face.
From this story, you will learn that the people around you really affect who you are, and how important it is to have the support of family and friends in your life. I have learned a lot from this book, and I think that anyone who reads it will too. I hope you enjoy this book as much as I did.
I am now reading more Walter Dean Myers’ books. A lot of his books are about growing up in Harlem, just like he once did. He has become my favorite author.

【推荐3】I grew up in a house with an unusual design feature. The floor of part of the house was made of pieces of chalkboards that my father gathered from the local high school when it was repaired. He added a second large piece on the wall, too.
The result was that we always had a place to write notes, draw pictures, do quick calculations, and keep an ongoing grocery list to which anyone could contribute. The wall chalkboard was used for important notes, while the floor was most handy for messages that were meant to catch someone’s eye the moment they came in the house, things like “I’ve run out to the store, back in 30 minutes” or “Please start dinner at 5:30”.
When I was young, I thought that every house would have a large writing area, but then I moved away and realized that wasn’t the case. For years, especially since having kids, I’ve tried to keep information organized. Though my Moleskine paper planner has given some semblance (表象) of order to my life, it doesn’t make up for a good chalkboard.
But now things have changed. I’m pleased to say that a proper chalkboard has finally been fixed in my kitchen—something that should have happened years ago! My dad recently came for a visit and brought a piece of slate (石板) that fits the wall behind the door, adding a board for chalk.
All of a sudden we have an obvious place to go to store information where all family members can see it, a place where important thoughts can be written down.
I think every house should have a proper-sized chalkboard — a real slate one, if you can find it. It’s a game-changer, a family unifier, and an effective organizer. I may not have a chalkboard floor, but once again I have a chalkboard wall, and now my home feels complete.

【推荐1】China has become the third country to discover a new lunar mineral, behind the US and the former Soviet Union. It is named Changesite-(Y), after the mythological Chinese goddess of the moon, Chang’e.
The rare lunar crystal (晶体) was found from the samples collected from the moon in 2020. Transparent and roughly the width of a single human hair, it formed in a region of the moon that was volcanically active around 1.2 billion years ago, which is giving scientists hope of providing limitless power for the world. The crystal is made of material previously unknown to the scientific community and contains helium-3, which scientists believe may provide a stable fuel source for nuclear fusion reactors (核聚变反应堆). The element is incredibly rare on Earth, but it seems to be fairly prevalent on the moon.
For decades, scientists have been interested in helium-3 and its potential source of fuel for nuclear fusion. Nuclear fusion reactions occur naturally, when two light atoms combine into a heavier one, under extreme pressure and heat. They take place inside stars, but humans have yet to create a fusion reactor with enough energy to start the process.
Although it is too early for scientists to have made any financial estimates on such a fuel source, it will undoubtedly be extremely costly. There is, of course, the matter of bringing the crystals back from the moon, especially in the large amounts that are needed to fuel fusion reactors.
Multiple private companies and countries with space agencies have signaled their intentions to mine the moon for helium-3, and this latest discovery could start the race.

【推荐2】Chinese space scientists have announced new discoveries made by Yutu-2, the first robot rover ever to explore the far side of the Moon, which permanently faces away from the Earth.
Commanding a rover on the Moon’s far side presents big challenges: the Earth is always out of sight, so radio commands and data have to be bounced back and forth using a special relay satellite orbiting in space beyond the Moon. The rover relies on solar power, so it has to shut down most of its operations for two weeks of every month during a long period of lunar night. Since rolling onto the Moon from its Change’s-4 lander in January 2019, Yutu-2 has been operating on the Moon for more than three years, making it the longest ever mission to explore the lunar surface.
One of the rover’s main findings is that the soil on the far side of the Moon is a lot stickier than on the near side — so it’s more likely to stick in Yutu-2’s wheels. That’s because on the far side rocks have had more continuous attacks from tiny bits of space dust that heat the rocks in the soil and make them stick together in pointed shapes.
Yutu-2’s journey through the lunar landscape is very slow — so far it has covered just over 1, 000 metres in three years. Along the way to either side of its path, it has spotted 88 small bowl-shaped craters (坑). Scientists think these are secondary impact craters, formed when bits of rocks were thrown out by a much bigger impact. A far larger one, called Zhinyu, was created when a big space rock hit the Moon.
As Yutu-2 continues to explore its surroundings, researchers are excited about what else it might discover. Sara Russell from London’s Natural History Museum told New Scientist magazine, “It’s like this whole new world to explore. We really have a lot to find out about the far side of the Moon; it’s really exciting.”

【推荐3】For the first time, scientists have grown plants in moon soil collected by NASA’s Apollo astronauts.
Seeing the results, Robert Ferl of the University of Florida’s Institute of Food and Agricultural Sciences said, “Plants actually grow in lunar stuff. Are you kidding me?” He and other researchers planted thale cress, a small flowering plant, in moon soil returned from the Apollo missions.
The good news was that all of the seeds grew. The bad news was that after the first week, the lunar soil stressed the plants so much that they grew slowly. Most of the moon plants were stunted. The longer the soil was exposed to radiation (辐射) and solar wind on the moon, the worse the plants seemed to do. The soil collected by the Apollo 11 mission was the least helpful for growth.
Simon Gilroy of the University of Wisconsin-Madison said,“ This is a big step forward to know that you can grow plants.” Gilroy added, “The real next step is to go and do it on the surface of the moon.”
Moon dirt is full of glass particles (颗粒), which got in the Apollo lunar landers and wore down the moonwalkers’ spacesuits. One solution might be to use younger geologic (地质的) spots on the moon, like lava flows (熔岩流), for digging up soil. The environment also could be changed by adding special nutrient mixtures or artificial lighting.
Only 382 kilograms of moon rocks and soil were brought back by the six Apollo crews that landed on the moon. Most of them are still locked away, forcing researchers to experiment with soil made of volcanic ash on Earth. In 2021, NASA finally gave out 12grams of soil to the University of Florida researchers for the planting experiment. NASA said the timing for such an experiment was right, with the space agency looking to put astronauts back on the moon soon.

【推荐2】Cheng Feng is a teacher in a rural primary school. Yet, to many of her students, the 33-year-old is more than that. Cheng’s care for her rural students has extended beyond the classroom and makes her a mother figure to them all.
During the just past summer vacation, Cheng didn’t take time off but paid home visits to rural students of the Liling Primary School, which is nestled in the mountains more than 120 kilometers from the central area of Poyang County, East China’s Jiangxi Province.
Most students have been left behind by their parents, who have to go to work far away from home, and they are looked after by their grandparents.
“Seeing these special families and special children, I realized the importance of Fural education, and it is one of the major reasons why I have stuck around all these years, ” says Cheng, who also grew up in Poyang.
After learning that one of her students, Tan Yeting, and her brother were just scraping by on the low income of their grandparents’ handmade broom business, Cheng would pay regular visits to Tan’s home.
She would walk the two children through their homework assignment, enjoy beautiful rural scenery with them and cut their hair. These interactions have helped both children grow in confidence and shake of their timid nature at school.

【推荐3】American folklore (民间传说) is filled with tales of imaginary heroes like Pecos Bill and the Lone Ranger. Yet, besides those characters, there are real historical figures whose lives and fascinating deeds were mythologized (当做神话) over the years. Among them there is an apple grower, known by the popular nickname Johnny Appleseed. This man is said to have traveled on foot across the United States, planting apple trees.
Appleseed's real name was John Chapman. Chapman was widely known by the pioneers settling in the western lands in the 1800s. And the native Indians respected him as a "white medicine man". However, not much is known about Chapman's early life, except that he was born in a north-eastern state in 1774 and that his mother died soon after that, It's also said that he grew up on his father's farm, where apple trees grew.
Appleseed's legend began when he planted his first apple trees in Pennsylvania in 1798. Then, he began traveling west. Walking for miles every day and sleeping outdoors, he planted apple trees near settlements, where he sold them to the pioneers. His apples, which were not suitable for eating due to their bitter taste, were used to make cider (苹果酒). This became a common drink for the pioneers, especially in places where clean drinking water wasn't available.
By 1806, Chapman had been given his new name, and stories about him had spread among the pioneers. Most of these focused on his survival in the wilderness Chapman was also known for his eccentric clothing: instead of a shirt, he wore a cloth bag with holes for his head and arms, and he wore no shoes. He is also said to have carried a bag of apple seeds and have had a meal pot on his head as a hat.
When Appleseed died in 1845, he had walked across three western states. And he was the owner of five square kilometers of land. Appleseed's story was first published in an article in 1871. Yet, not all the details in this article and the ones published later were based on facts. Appleseed's legend has grown over the years through songs, stories and plays and modern-day Disney productions.
