Five "remains" floating in space, each with significant contributions to the field of science
Five "remains" floating in space
Space has been aspired to by human beings since ancient times. In ancient times, people, without advanced detection equipment and relying only on the naked eye to observe the stars, also had a certain understanding of space, and we have to marvel at the wisdom of the ancients.
Today, with the advancement of human technology, the emergence of astronomical telescopes has made space less mysterious, through which we can see the Moon, Mars, the Sun, and other distant galaxies. However, with the progress of human technology, we realized the dream of flying out of the Earth.
People out of the Earth, only to find the vastness of the universe, to know how ignorant the original understanding, the universe is so big, the Earth before even dust is not counted, only really out of the Earth, only to know the vastness and mystery of the universe, to get out of the Earth.
A new professional astronaut was born to explore the universe and the tomorrow of mankind. They enter space with the hope of mankind, but also face many unknown dangers, to know the space environment is completely new to humans, no gravity vacuum environment, a variety of strong cosmic radiation, and some other unknown dangers that can threaten the lives of astronauts.
Due to the uncertainty of the cosmic environment, the space environment is very dangerous, astronauts naturally will not have to sacrifice, at present, humans in the cause of space exploration, and 18 astronauts have sacrificed their lives. In addition to the astronauts' contribution to the human space career, many scientists who have made great contributions to the space force have also made great contributions to this cause. Some scientists have dedicated their lives to the cause of space and return to the universe after death. Today, I would like to introduce to my friends five people who have contributed to the cause of human spaceflight and died floating in space, with space as a companion.
Three of these beautiful space "remains" are Soviet cosmonauts, the spacecraft they were riding in space after 23 days of flight, due to docking with the space station, in connection with the space station, a vibration occurred, causing the return capsule air leakage, three cosmonauts were directly exposed to the vacuum, just 40 seconds, they died of acute lack of oxygen and boiling of body fluids, and thus remained in space forever.
The last body was that of an astronomer named Tombo, the discoverer of Pluto, a name that many people may not have heard, who discovered the planet in 1930 based on the predictions of other astronomers. Pluto used to be one of the nine planets in our solar system, but later scientists decided it was too small to be more than a dwarf planet, so they removed it from the nine planets, and since then there have only been eight planets in our solar system.
After Creed-Tombaugh's death, his ashes were mounted on the New Horizons probe in his memory. According to its mission, New Horizons will explore objects beyond Pluto's orbit and then further into the edge of the solar system, so New Horizons will carry Clyde Tombaugh's ashes out of the solar system.
The "remains" of a scientist named Yukinshumek, who could be called a genius, graduated from university at the age of 19 and from his master's degree at the age of 20. He was one of the pioneers and founders of planetary science. This is also the only person buried on a celestial body other than the Earth. As one of the scientists who discovered natural Koch quartz, Shumaker and two other geologists discovered natural Koch quartz, a discovery that became one of the key pieces of evidence that the Barringer crater was more likely formed by a meteorite impact.
Eugene Shoemaker was killed in a car accident on July 18, 1997, while on an expedition to impact craters in Australia. The Australian crater Schumaker, the asteroid Schumaker, and the NASA "Intersect-Schumaker" probe launched in 1996 are all named after the Schumaker crater.
All these remains have made great contributions to the cause of human space exploration and deserve our respect. Human civilization is developing in the process of continuous exploration, and also in the process of continuous understanding of the universe, as well as a continuous progress. The cause of human space exploration has just begun and will face more challenges in the future, and naturally, no other astronaut will pay the price of his life for this.
Humans are not yet considered a true interstellar civilization, at best, it is a technical civilization. In the interstellar voyage, we have not yet fully mastered the technology, space on the spacecraft still needs rocket boost, and our ship is still too slow to leave the solar system, let alone explore other galaxies.
When and when humans make a breakthrough in speed, with the ability to fly at sublight speeds, then humans can go out of the solar system and explore some nearby galaxies, only to be considered the initial entry into interstellar civilization. But when humans are out of the solar system, they same will face greater danger. Please remember, in addition to humans, there are other Earth civilizations in the universe.
Although with the current technology of human beings, no extraterrestrial life and alien civilizations have been discovered, scientists do not doubt that there are other intelligent civilizations in the universe. Today, we can't go out of our solar system, so naturally, we can't discover extraterrestrial life and civilizations, but humans will likely have contact with extraterrestrial civilizations once they can go out of our solar system and be in a galaxy beyond our solar system.
Whenever humans meet with an extraterrestrial civilization, it is unknown whether it will be a friendly exchange or an outbreak of interstellar war. Sorkin has said that aliens are not necessarily friendly. Whenever we encounter a hostile alien civilization, war is inevitable, and this brings unknown dangers to human civilization. It is true that although there are various unknown dangers in the universe, they cannot stop the enthusiasm of human beings to explore the universe and their desire for it, and they are also the path to glory.
Only by constantly striving forward, human beings can gradually become stronger, go out of the solar system, go through the galaxy, colonize various planets, and let human steps go through every corner of the galaxy. Then from the galaxy to other galaxies, and eventually become the most important civilization in the universe.

National Security Trial for Hong Kong’s Tiananmen Activists Begins
A national security trial in Hong Kong has officially begun for activists who have long campaigned for justice regarding the Tiananmen Square crackdown of 1989. The trial marks a pivotal moment in the city’s ongoing struggle between preserving civil liberties and the increasing influence of Beijing over its legal and political systems. The proceedings have drawn international attention, shedding light on the challenges faced by pro-democracy activists in Hong Kong and raising questions about freedom of expression under the city’s national security laws. Background: The Tiananmen Activists The activists on trial are part of a group that has spent decades advocating for recognition of the June 4, 1989, Tiananmen Square massacre in Beijing. While Hong Kong traditionally allowed public commemoration of the event, the situation changed following the 2020 imposition of a sweeping national security law by Beijing. The law criminalizes acts of secession, subversion, terrorism, and collusion with foreign forces. Critics argue that its broad definitions have been used to target pro-democracy activists and silence dissenting voices, including those who peacefully campaign for historical accountability. What the Trial Entails The trial, held in a Hong Kong court, involves several prominent activists who have been charged under the national security law. Charges include alleged subversion and acts perceived as undermining state authority. The proceedings are expected to last several weeks, with the outcome likely to have far-reaching implications for Hong Kong’s civil society. Observers note that this case is emblematic of the shrinking space for political activism in the city. Legal experts warn that convictions could deter future generations of activists from speaking out on sensitive historical or political issues. Hong Kong’s Changing Legal Landscape Hong Kong’s legal system has long been seen as a cornerstone of its autonomy, known as “one country, two systems.” The city’s courts were traditionally respected for their independence and adherence to common law principles. However, the national security law has dramatically altered this landscape. Many legal analysts argue that the law gives authorities broad powers to define what constitutes a threat to national security, limiting judicial discretion and eroding long-standing protections for civil liberties. The Tiananmen activists’ trial is one of the first high-profile cases to test the law’s reach and its consequences for political expression. International Reaction The trial has elicited strong reactions from around the world. Human rights organizations, foreign governments, and international media have expressed concern over what they see as a crackdown on free speech and civic engagement in Hong Kong. Statements from organizations like Amnesty International and Human Rights Watch emphasize that peaceful commemoration and historical advocacy should not be criminalized. Meanwhile, some governments have reiterated calls for Beijing and Hong Kong authorities to respect international human rights standards and allow activists to participate freely in political discourse. Impact on Civil Society For Hong Kong’s civil society, the trial is both a warning and a moment of reflection. Community groups and advocacy organizations fear that prosecutions under the national security law could create a chilling effect, discouraging citizens from participating in public debates or organizing commemorative events. Despite these challenges, activists continue to push for transparency and accountability. Many are using digital platforms and international forums to raise awareness about the trial and maintain public engagement with Tiananmen-related issues. Voices From the Activists The defendants and their supporters have emphasized that their work is centered on remembrance, education, and human rights advocacy. They argue that commemorating the victims of the 1989 crackdown is a moral and civic duty, not a threat to national security. Statements from family members and fellow activists highlight the personal risks involved in speaking out in Hong Kong today. They stress that the trial is not just about individual charges but represents a broader struggle for freedom of speech and the right to historical memory. What’s Next Legal experts predict that the trial could set important precedents for how Hong Kong applies its national security law in cases related to historical activism. The outcome may influence how other activists approach political expression, commemoration, and protest in the city. International observers will be closely monitoring the proceedings, both for legal developments and for broader indications of Hong Kong’s political trajectory. The trial serves as a test of how the city balances security concerns with fundamental freedoms that have long defined its identity. Conclusion The national security trial for Hong Kong’s Tiananmen activists is more than just a courtroom event; it is a symbol of the ongoing tension between state authority and individual freedoms. As the proceedings unfold, the world is watching closely to see how Hong Kong navigates its commitment to justice, memory, and human rights under the pressures of political change. For the activists, this trial is a continuation of a decades-long struggle to ensure that the events of Tiananmen Square are neither forgotten nor ignored. For the citizens of Hong Kong, it is a reminder of the fragile balance between freedom and security in a rapidly evolving political landscape.

US Warns Airlines About Military Activity in Parts of Latin America
Commercial aviation is built on predictability—clearly defined airspace, coordinated air traffic control, and shared international rules. When that predictability is disrupted, even subtly, the ripple effects can stretch far beyond the cockpit. That is exactly why a recent warning from the United States has caught the attention of airlines, governments, and travelers alike. In early 2026, US aviation authorities issued an advisory warning airlines about military activity in parts of Latin America, urging pilots to exercise heightened caution when flying over certain regions. While no immediate restrictions or flight bans were imposed, the message itself was clear: something in the skies has changed, and the risks—however limited—can no longer be ignored. This development is not just about aviation safety. It reflects a growing intersection between geopolitics, military operations, and civilian infrastructure in a region that has long balanced cooperation with tension. What Exactly Did the US Warn About? The advisory, released through official aviation safety channels, highlighted concerns over potential military activity affecting airspace across parts of Mexico, Central America, South America, and nearby oceanic regions. Airlines were advised to remain vigilant during all phases of flight, including cruising at high altitudes, takeoff, and landing. Unlike routine notices related to weather systems or airport congestion, this warning explicitly referenced security-related risks. These include the possibility of unexpected military movements, temporary airspace disruptions, and interference with navigation systems that modern aircraft rely on for safe operations. Importantly, the warning did not accuse any specific country of wrongdoing, nor did it suggest an immediate danger to passengers. Instead, it served as a precaution—one designed to ensure airlines adjust flight planning, monitoring, and communication protocols accordingly. Why Military Activity Matters to Civil Aviation To the average traveler, military exercises or operations may seem distant from the experience of flying on a commercial jet. In reality, the two worlds often share the same skies. Civilian aircraft depend heavily on satellite navigation, coordinated air traffic control, and stable airspace rules. Military operations—especially those involving fast-moving aircraft, surveillance systems, or electronic equipment—can introduce uncertainty into that environment. Some of the key risks aviation authorities monitor include: Unplanned military aircraft movements that may not follow civilian flight patterns Temporary airspace closures or restrictions that require last-minute rerouting Navigation signal disruptions, whether accidental or intentional Increased congestion in strategic corridors used by both civilian and military flights While these risks are typically managed through coordination and communication, heightened military activity raises the stakes. The FAA’s advisory suggests that such activity has reached a level where additional caution is warranted. The Geopolitical Context Behind the Warning The timing of the advisory is not accidental. Latin America has seen a noticeable rise in security operations and military coordination involving the United States over the past year. These efforts are largely focused on counter-narcotics missions, maritime security, and regional stability, particularly in areas with strategic shipping routes or ongoing political tension. At the same time, broader global dynamics—ranging from great-power competition to shifting alliances—have increased the strategic importance of air and sea routes across the Western Hemisphere. From Washington’s perspective, issuing an aviation warning is not about alarmism. It is about acknowledging that military and security activities in the region may temporarily affect civilian systems, including aviation. How Airlines Are Responding For airlines, advisories like this are not unusual—but they are taken seriously. Most major carriers already operate with layered safety systems that allow them to respond quickly to changing conditions. In practical terms, this warning may lead to: Slight route adjustments to avoid specific airspace Enhanced pilot briefings before flights Increased coordination with air traffic controllers Closer monitoring of navigation and communication systems So far, there have been no widespread flight cancellations or suspensions linked directly to the warning. That suggests airlines view the risk as manageable, provided proper precautions are followed. Reactions from Latin American Governments Some governments in the region have been quick to reassure the public. Officials have emphasized that their national airspace remains safe and fully operational, and that civilian flights continue without disruption. This response highlights an important tension: while the US warning is precautionary, it can still affect public perception. Tourism, business travel, and investor confidence are all sensitive to suggestions of instability—even when no immediate danger exists. As a result, many countries are walking a careful line between cooperating on aviation safety and defending their reputation for stability. What This Means for Passengers For travelers, the key takeaway is simple: commercial aviation remains safe. Warnings like this are designed to prevent incidents, not predict them. Passengers flying through or over affected regions may experience slightly longer flight times or minor schedule adjustments, but there is no indication of increased danger to civilian aircraft. In fact, the existence of such advisories demonstrates how seriously aviation authorities take even low-probability risks. A Sign of a More Complex World The US warning to airlines is a reminder that modern air travel does not exist in a vacuum. As military operations, security concerns, and geopolitical rivalries evolve, civilian systems—from shipping lanes to flight paths—are increasingly affected. This moment underscores a broader reality: the skies are becoming more crowded, more contested, and more interconnected with global politics. Managing that complexity will require continued transparency, cooperation, and vigilance from governments, regulators, and airlines alike. For now, planes continue to fly, passengers continue to travel, and the system continues to work. But behind the scenes, aviation authorities are quietly adjusting to a world where safety is shaped not just by weather and mechanics—but by geopolitics as well.
