Eileen Gu became the first freestyle skier to win three medals in a single Olympics at the 2022 Winter Olympic Games in Beijing, China. Gu won gold medals in women’s ski big air and women’s halfpipe, as a member of the Chinese team. She also won the silver in women’s ski slopestyle at the 2022 Games. Gu is a popular Chinese-American freestyle skier, nicknamed “Frog Princess” for a green helmet she has worn in competition.

Gu competes in the halfpipe, slopestyle, and big air events. The halfpipe is an acrobatic event performed in a deep trough. In slopestyle, competitors perform on special courses that feature various obstacles. Big air involves a long, high jump during which the skier performs acrobatic moves.

Eileen Feng Gu, also called Gu Ailing, was born on Sept. 3, 2003, in San Francisco, California. Her mother, Yan Gu, immigrated to the United States from China. Gu grew up in San Francisco, raised by her mother and grandmother. She began skiing at 3 years old and freestyle skiing at 8 years old. She became a professional at age 16. Gu became the first student to graduate San Francisco University High School in three years in 2020.

Gu began her career representing the United States. She chose to represent China beginning in 2019, becoming a naturalized Chinese citizen. At the 2020 Youth Olympic Games in Lausanne, Switzerland, Gu won gold in big air and halfpipe, along with silver in slopestyle.

Gu became the first woman freestyle skier to land a double cork 1440—a trick that includes four horizontal rotations of 360 degrees and two vertical rotations—in November 2021. She became the first Chinese freestyle skier to earn multiple medals at the World Championships, with gold medals at the 2021 World Championships in Seiser Alm, Italy, and the 2022 World Championships in Calgary, Alberta, Canada. Gu became the first Chinese X Games champion at the 2021 games in Aspen, Colorado. She was the only woman to compete in three disciplines and the first rookie to win three medals, earning gold in slopestyle and superpipe, a variation of the halfpipe, and bronze in big air.

Besides skiing, Gu has also had a successful modeling career. She has modeled for high fashion brands including Chanel, Louis Vuitton, and Tiffany and Co.

American figure skater Nathan Chen clinched his highly anticipated and long-awaited first gold medal at the 2022 Winter Olympic Games in Beijing, China. The men’s figure skating event is decided by combining scores from the short and long programs. At the 2022 Games, Chen set a world record in the men’s short program with a score of 113.97. The previous record was set by Japan’s Olympian Yuzuru Hanyu, with 111.82 in 2020. Chen has been gunning for gold since his last Olympic performance, in which Hanyu took gold at the 2018 Winter Olympic Games in Pyeongchang, South Korea.

Chen was a member of the United States team that won a bronze medal in team figure skating at the 2018 Games. Chen finished fifth in the men’s figure skating event at the 2018 Games, while cementing his nickname, the “Quad King.” He made Olympic history by becoming the first skater to land six quadruple jumps in one program. In a quadruple jump, the skater jumps and makes four full revolutions in the air.

Chen won the men’s World Figure Skating Championship sponsored by the International Skating Union (ISU) in 2018, 2019, and 2021. The ISU is the governing body of international figure skating. Chen also won the Grand Prix of Figure Skating Final in 2017, 2018, and 2019. The Grand Prix, organized by the ISU, includes six international figure skating events leading to a Final competition for the top skaters.

Chen won six U.S. Figure Skating Championships (also called the nationals, or U.S. Championships), consecutively from 2017 to 2022. U.S. Skating is the national governing body of figure skating in the United States. The organization sponsors competition at many levels, including novice, junior, and senior competitions that lead to national titles. During the U.S. nationals in 2017, Chen became the first skater to land five quadruple jumps in one program.

Chen was born on May 5, 1999, in Salt Lake City, Utah. His parents emigrated from China to the United States in 1988. Chen began skating at the age of three. He entered his first figure skating competition in 2003, at the age of four. Chen won the national novice title at the U.S. Championships in 2010, the youngest novice champion in the history of U.S. Figure Skating. For the 2011-2012 season, Chen moved up to the junior level and won the junior men’s title in 2012. He won the bronze medal at the 2014 World Junior Championships. He won the gold medal in the Final of the 2015 Junior Grand Prix.

The 2022 Winter Olympic Games commence this Friday, February 24, with the arrival of the legendary Olympic torch in Beijing, China. The torch was lit in Olympia, Greece, in October 2021 and began making its way to the Chinese capital. From February 2 to 4, it was carried by more than 1,000 people across the cities of Yanqing and Zhangjiakou and into Beijing. The procession included the first Olympic torch handover from robot to robot—underwater! Audiences were limited in person due to the ongoing COVID-19 pandemic, so many watched the torch’s progress online.

The Games officially begin after the opening ceremony on Friday evening. The ceremony takes place at the National Stadium, nicknamed the “Bird’s Nest,” which was originally built for the 2008 Summer Olympic Games. The themes of the ceremony showcase China’s “willingness to pursue world peace” and celebrate the Beijing Games’ slogan, “together for a shared future.” However, multiple countries’ officials will not be attending the Games in protest of human rights violations.

To keep athletes and Beijing residents safe from illness, international spectators will not be allowed to attend the events, and additional safety measures have been put in place. There will be 3,000 performers at the ceremony. The vast majority will be teenagers, who are at low risk of long-term health effects from the disease. Small groups of spectators will be invited to watch events at the Games as long as they abide by COVID-19 safety protocols.

Beijing is holding a record number of sporting events, with 109. There are seven new events at the Beijing 2022 Olympics in skiing, snowboarding, and monobob—that is bobsledding with a single athlete. Many events focused on mixed-gender teams, giving Beijing the greatest balance of women’s and men’s events in the Olympics yet.

The mascot of the Beijing 2022 Olympic Games is a panda named Bing Dwen Dwen, from the Chinese words meaning ice and children. The design features a spacesuit to embody the future and a heart on Bing Dwen Dwen’s left paw to symbolize Chinese hospitality.

A wild elephant herd has captured global attention and baffled, well, everyone. Fifteen elephants, including three calves, have been on a mysterious trek across their native China. Traveling for over a year, the migration has taken them more than 300 miles (500 kilometers) from home. Their natural habitat is thought to be the Mengyangzi Nature Reserve in Xishuangbanna, Yunnan. Reserves are areas of land set aside to protect the habitats of elephants and other wild animals. China only has about 300 wild elephants. Most live in the south of the Yunnan province.

The traveling herd gained fame in China despite trampling crops, damaging property, and occasionally poking a trunk through someone’s window. The elephant’s padded feet enable them to walk and run with surprisingly little noise. Elephants normally walk at a speed of 3 to 6 miles (5 to 10 kilometers) an hour. When making a long journey, a family walks at about 10 miles (16 kilometers) an hour.

The elephants might have been looking for a new habitat, though they wouldn’t find one among millions in the city Kunming. Paths were cleared and food was provided as towns moved to protect the elephants.

Safety is a high priority for the endangered Asian elephant. Local government launched drones and mobilized hundreds of people to protect the herd’s migration. People attempted to steer the elephants in the southwest direction, back toward the reserve. However, the herd may have decided to head home all on their own.

Elephants are extremely strong and highly intelligent. There are two kinds of elephants, African elephants and Asian elephants, also known as Indian elephants. Asian elephants live only in southern and southeastern Asia. They are found in forests and jungles of Cambodia, China, India, Indonesia, Malaysia, Myanmar, Sri Lanka, Thailand, and Vietnam.

Today, wildlife experts agree that elephants are in great danger and need human protection to survive. The number of wild elephants has greatly declined because people kill elephants for their ivory tusks. Farming and industry threaten the natural resources needed by elephants to survive. In Asia, human population growth and habitat destruction have severely reduced the number of wild elephants. Scientists estimate that only about 40,000 Asian elephants survive in the wild.

An adult Asian bull stands from 9 to 101/2 feet (2.7 to 3.2 meters) tall at the shoulder and weighs up to 8,000 pounds (3,600 kilograms). Asian cows stand about 8 feet (2.4 meters) tall and weigh about 6,600 pounds (3,000 kilograms).

Most Asian elephants have light gray skin and may have pink or white spots. Most Asian bulls have tusks that grow from 4 to 5 feet (1.2 to 1.5 meters) long. However, some Asian males, called makhnas, have no tusks, and many Asian females have none. Other Asian females have extremely short tusks called tushes.

Mars is one of the most difficult destinations to arrive safely at in the solar system, but you might not know it if you have been paying attention to the news lately. Earthlings are a perfect three-for-three on Mars missions this February. Two countries saw their first missions ever arrive at the Red Planet last week. Then yesterday, the United States National Aeronautics and Space Administration (NASA) landed the Mars 2020 rover Perseverance on the surface of Mars. This flotilla of missions to the Red Planet was facilitated by a favorable alignment in the middle of 2020 that brought the planet close to Earth.

On February 9, a spacecraft from the United Arab Emirates (UAE) arrived in orbit around Mars. The orbiter, called Hope or Amal, will map Martian weather on a planet-wide scale. Such mapping has never been attempted before. UAE became just the fifth country to reach the planet. All systems look good at the moment, but Hope is due to enter the orbit from which it will conduct its mapping in May. At that point, engineers will know for sure if the probe will be able to accomplish its mission.

Hot on Hope’s heels was an ambitious mission sent by the China National Space Administration (CNSA). The mission, called Tianwen-1, went into orbit around Mars the next day. The mission consists of an orbiter, a lander, and a rover. The lander and rover will attempt a landing in a few months. If CNSA successfully deploys Tianwen-1, China will become the third country to land a spacecraft on Mars and just the second to land a rover on Mars.

The last—but certainly not least—to arrive was Perseverance. The rocket carrying the beefy rover blasted off from Cape Canaveral in Florida on July, 30, 2020. Perseverance is the largest rover ever sent to Mars. It’s the size of a small automobile and weighs over 2,200 pounds (1,000 kilograms) on Earth.

Unlike China and the UAE, the United States is a Mars veteran. NASA has landed several successful missions there, including the still-operational sibling craft of Perseverance, the Mars Science Laboratory (MSL) rover Curiosity.

The design of Perseverance is based on that of Curiosity, which has been exploring Mars since 2012. Engineers used many extra components that were originally created as backups for Curiosity in case of manufacturing defects in the originals. But Perseverance is more than just a pile of spare parts. Jet Propulsion Laboratory (JPL) scientists and engineers modified—and beefed up—the design to fit Perseverance’s mission. Perseverance is about 5 inches (13 centimeters) longer and 278 pounds (126 kilograms) heavier than Curiosity.

No matter how many successful missions are under a space agency’s belt, getting a spacecraft to Mars is a heart-pounding ordeal. Landing on the Red Planet is especially challenging. Mars is a large planet, so its gravity pulls spacecraft towards it at high speed. It lacks a thick atmosphere like that of Earth, however, that spacecraft could use to slow down. Furthermore, retrorockets placed on the rover would scour the ground near the landing site and contaminate it with rocket exhaust.

JPL has developed a complex of system to land a large rover on the Martian surface, which was first used with MSL. A parachute slowed the craft after it entered the Martian atmosphere. A set of rockets then fired to hover the craft above the surface. Then, Perseverance was lowered to the ground on a tether. Mission planners call this complicated ride through the atmosphere, filled with opportunities for mission-ending disaster, “the seven minutes of terror.”

Perseverance touched down in Jezero Crater. Billions of years ago, the crater held a lake that was fed by a river system. Perseverance will explore this ancient river delta and search for signs of past life there.

Perseverance carries many sophisticated scientific instruments that will enable it study the geology and climate of the region. The rover is equipped with a special drill and sample vials. After studying the rock samples it has drilled, it will place them in sealed vials and cache (stow) them on the surface. Scientists hope to recover the cached vials and send them to Earth in an ambitious sample return mission in a decade or so.

Other special features included an upgraded autonomous driving package, which will enable Perseverance to pick its way through obstacles on its own to reach a target, and a small helicopter drone called Ingenuity that will look to demonstrate the first powered flight on a solar system body other than Earth. Expect to hear about more exciting discoveries—and see more stunning pictures of Mars—in the months and years ahead.

Last week, on February 19, the Wuhan coronavirus epidemic claimed its 2,000th victim. First recognized in human beings in the Chinese city of Wuhan in December 2019, the coronavirus has since spread steadily and touched nearly all parts of the world. Wuhan coronavirus is an informal name for a respiratory disease named Coronavirus Disease 2019 (COVID-19). Coronaviruses are one of many virus types that cause the common cold and other diseases of the upper respiratory system. The COVID-19 is a pneumonia-like disease. Its symptoms include breathing difficulties, coughing, and fever. It is a contagious disease, and the symptoms can be fatal in a small percentage of cases.

On Jan. 30, 2020, when the disease had caused 170 deaths in some 8,000 confirmed cases, the World Health Organization (WHO) declared the virus outbreak to be a public health emergency of international concern. The WHO recommended urgent containment measures as the number of cases and deaths continued to climb. By mid-February, more than 40,000 cases of the virus had been confirmed. The disease was given the temporary name 2019-nCoV, for novel (new) coronavirus of 2019. It was later officially named COVID-19. The virus that causes the disease was named SARS-CoV-2.

September 25, 2019

Since June 2019, massive protests have taken place in Hong Kong, a special administrative unit of China. The city and region of Hong Kong—located on a peninsula and group of islands—enjoy a high degree of autonomy (self-rule). Hong Kong maintains a free-enterprise economy within China’s Communist economic system. The “one country, two systems” relationship is not always a happy one, however, and the people of Hong Kong often resent being subjected to mainland China’s different rules.

In June 2019, the largest protests in Hong Kong’s history were triggered by a proposed bill that would have allowed people Hong Kong accused of crimes in to be extradited (handed over) to stand trial in mainland Chinese courts. (Hong Kong also has a separate legal system from the rest of China.) More than a million people participated in the protests. The protesters believed the extradition bill endangered their rights. Hong Kong police clashed with the protesters, who also called for democratic reforms, and many people were arrested or injured. Protesters then added investigations into police brutality to their demands.

On June 15, the Hong Kong Chief Executive Carrie Lam (Hong Kong’s governor) suspended the proposed extradition bill, but massive protests continued the next day as more than 2 million people took to the streets. (Hong Kong’s entire population is 7.4 million.) The unrest continued into July as protesters stormed the Hong Kong parliament, ransacking offices and clashing with police. In reaction, pro-Communist government gangs attacked some pro-democracy protesters. Many people were hurt in the confrontations, and hundreds of people were arrested.

Amid rising tensions in August, protesters began crowding into police stations as well as into busy Hong Kong International Airport, which was forced to close for several days. Fears of Chinese military intervention—with flashes back to the Tiananmen Square protests of 1989—rose as the army paraded in Shenzhen, just across the border from Hong Kong. Those fears went unrealized, however, and although standoffs between protesters and police continued, violent episodes were relatively rare considering the massive numbers of people involved.

In early September, Chief Executive Lam formally withdrew the extradition bill that ignited the protests. But unrest lingers as the people of Hong Kong continue to push for greater democratic freedoms, universal suffrage (the right to vote), and solutions to housing and land shortages in the densely populated metropolis.

The United Kingdom controlled Hong Kong from 1842 until 1997, when it returned to Chinese control. The “one country, two systems” relationship was created to safeguard the democratic freedoms enjoyed by Hong Kong citizens under British rule. The Chinese government has eroded some of these freedoms, however, and pro-democracy protests have occurred—with much less intensity—in Hong Kong for the last several years.

June 5, 2019

In the early morning hours of June 4, 1989, 30 years ago yesterday, Chinese government troops killed and wounded thousands of protestors in Tiananmen Square, a large public area in Beijing, China. The violent incident was the climax of nearly two months of protests for political and economic reform in the tightly controlled Communist country. Chinese officials stated that some 200 people died in the June 4 incident (often remembered in China as “6/4″). However, international observers said that more than 1,000 people were killed, and thousands of other people were injured. The protests and the military response were widely televised. Many people throughout the world expressed support and sympathy for the protesters.

On April 15, 1989, former Chinese Communist Party head Hu Yaobang died. He was known for his commitment to political and economic reform and was supportive of more freedom of expression. Hu had been removed from office in 1987 by government officials who thought his views were too liberal. However, those very views made Hu popular with many Chinese citizens, particularly students, who wanted more freedom.

After a decade of liberalization and growth, China not only experienced new prosperity, but it also witnessed the spread of inflation and corruption among government officials. The announcement of Hu’s death coincided with growing popular dissatisfaction and led to a spontaneous outpouring of grief by Beijing’s citizens. On April 16, 1989, people began gathering in Tiananmen Square to honor Hu’s memory.

The gathering to honor Hu quickly became a major protest led by students from Beijing universities. The protesters called for greater freedoms of speech and the press; increased funding for higher education; government openness; and an end to government corruption. A student-led hunger strike gained support from around the country and the world. Students and supporters from all over China traveled to Beijing to take part in the protests, which at times included more than 1 million people. Similar, smaller gatherings occurred in other Chinese cities.

At first, the government, led by Communist Party General Secretary Zhao Ziyang, adopted a moderate stance. However, as the protests continued, more conservative members of the ruling Chinese Communist Party believed they threatened the party’s legitimacy. Government officials, including Premier Li Peng, called for the use of force.

By the end of May, Li Peng had won the support of the paramount leader Deng Xiaoping. On May 20, Li declared martial law (an emergency government under military rule) and told the protesters to leave Tiananmen Square. Army and police troops headed toward Tiananmen Square, but Beijing residents built blockades in the streets to slow the advance. The blockades kept the troops and vehicles from the square for two weeks.

On June 3, the government said that protesters would be forced from the square if they did not leave on their own. That night, soldiers and tanks began firing. Many unarmed protesters were shot while trying to flee. A number of protesters attacked the troops with rocks and bottles. Some demonstrators set fire to military vehicles.

On June 4, as violence continued, government troops sealed off Tiananmen Square. In the days that followed, the government shut down protests in other cities and searched for the students who had led the demonstrations. Many of the student leaders fled the country.

People around the world expressed shock at the Chinese government’s actions. Diplomatic and economic relations between China and a number of other countries became strained. In the wake of the protests, the Chinese government further restricted free speech and democracy. General Secretary Zhao Ziyang was dismissed from his post for showing support for the protesters. Since 1989, Chinese government censors have banned news programs and other media presentations that discuss the June 4 incident.

October 1, 2018

Two weeks ago, early on the morning of Sept. 15, 2018 (September 14 in the United States), Typhoon Mangkhut struck the main Philippine island of Luzon. In a country accustomed to seasonal tempests, the Philippine Atmospheric Geophysical and Astronomical Services Administration (PAGASA) gives its own names to storms: there, Mangkhut (the named bestowed on the storm by the World Meteorological Organization) was known as Ompong. The typhoon raged regardless of name, causing deadly flooding and landslides that killed 95 people in Luzon. Mangkhut then killed one person on Taiwan and six others in China. On September 20, days after the storm dissipated, waterlogged soil on the central Philippine island of Cebu caused a landslide that killed another 85 people.

Typhoon Mangkhut formed as a tropical depression over the Marshall Islands in the North Pacific Ocean on September 7. The storm grew into a tropical storm near Bikini Atoll and escalated to a Category 5 (the strongest level) typhoon in the Northern Marianas. Mangkhut roared westward across the Pacific and on September 12 the storm entered the Philippine Area of Responsibility (PAR), the zone in the northwestern Pacific where PAGASA tracks dangerous weather.

In preparation for the massive storm, schools and public offices were closed in northern Luzon and people were evacuated from many coastal areas. Across the South China Sea in Hong Kong, officials issued a rare “No. 10” typhoon warning signal, the highest level of storm threat, and briefly shut down public services. Parts of China’s Guangdong Province also issued red alerts and closed schools and public offices.

Mangkhut reached the shores of Cagayán Valley, Luzon’s most northern administrative region, on September 15. The storm lashed Cagayán and the nearby Cordillera and Ilocos regions, where winds as fierce as 125 miles (205 kilometers) per hour ripped up trees and houses and torrential rains caused flash flooding and mudslides. Mangkhut then leapt to China, where deadly winds knocked down thousands of trees and shattered windows in swaying high-rise buildings. Floodwaters blocked roads and railways and inundated coastal communities. On nearby Taiwan, the lone death occurred when strong ocean currents related to the storm swept a beachgoer out to sea.

April 11, 2018

Last week, on April 1, China’s first space station, Tiangong-1, returned to its home planet in a fiery “uncontrolled return” through Earth’s atmosphere. Tiangong-1 (Heavenly Palace-1 in English) was launched in 2011 and ceased operating in 2016. The remnants of the unoccupied space station—the parts that did not disintegrate on reentry—crashed into the South Pacific Ocean.

The spacecraft’s demise was tracked closely by the United States National Aeronautics and Space Administration (NASA), the U.S. Air Force, and other space agencies and air forces around the world. The end of Tiangong-1 could have posed a threat to highly populated areas, and the derelict craft’s reentry position was continually updated as it spun through its final orbits. At last, Tiangong-1 hit the atmosphere over a wide expanse of empty sea. Most of the spacecraft was incinerated, but pieces of it did strike the water at Earth’s surface.

Tiangong-1 was launched aboard a carrier rocket from the Jiuquan Space Launch Center in northern China in September 2011. The modest space station, two cylindrical sections with a docking port, was about 39 feet (12 meters) long and 11 feet (3.3 meters) wide. The spacecraft was used mainly to carry out rendezvous and docking tests in preparation for the construction of a larger and longer-lasting space station scheduled for completion and launch in the early 2020′s. Tiangong-1 settled into an orbit about 217 miles (350 kilometers) above Earth, slightly lower than the orbit of the much larger International Space Station.

In early November 2011, the robotic Shenzhou-8 (Divine Craft-8) spacecraft visited Tiangong-1, executing China’s first-ever orbital docking. In June 2012, three taikonauts (Chinese astronauts) aboard Shenzhou-9 gave the heavenly palace life for about two weeks. A year later, three more taikonauts spent a fortnight aboard Tiangong-1. The spacecraft continued some Earth-observation work after that, but contact and control of Tiangong-1 were lost in March 2016. A successor craft, Tiangong-2, was launched in September 2016 and is currently in operation.
