I recently came across a rather amusing story about Neil Armstrong. Apparently, he once tried to sue a barber for selling his hair to a collector without his consent, turning a simple haircut into a strange chapter in space history. That quirky news item unexpectedly rekindled my fascination with space and everything connected to it.
Astronomy has always been a subject I’ve wanted to explore more deeply, especially through blogging. If circumstances had been different, I would gladly have pursued a career in space research—whether at the Hubble Space Telescope, NASA’s Jet Propulsion Laboratory, Cape Canaveral, Baikonur in Kazakhstan, or atop the mountains of Chile or Hawaii, gazing into the vast expanse of the universe. But life doesn’t always take us where we once imagined.
So instead, I turn to history. I read about the pioneers who shaped space exploration, hoping in some small way to feel connected to that extraordinary journey.

Dogs at the dawn of space
One story that stood out to me was about a stray dog from Moscow who, in many ways, paved the path for legendary figures like Yuri Gagarin and Neil Armstrong. Before humans ventured into space, animals were sent ahead to test the unknown. It may seem cruel—and by modern standards, it certainly was—but at the time these experiments were seen as necessary steps toward progress.
Laika, whose name means “barker” in Russian, became the most famous of these animal pioneers. She is often remembered as a symbol of early space experimentation, though her story carries a heavy ethical weight. In the early days of scientific testing, animals such as dogs, monkeys, mice, and guinea pigs were used to study how living beings responded to extreme conditions like radiation, acceleration, and confinement.
Long before Laika, even fruit flies were sent into space shortly after World War II, marking humanity’s first attempts to understand life beyond Earth. The launch of Sputnik 2 by the Soviet Union marked a turning point in the space race, a fierce competition between global superpowers. I remember reading about Laika in a sixth-grade science book, where she was portrayed as a brave space traveler. What the book failed to mention, however, was the tragic truth: Laika died just hours after launch. At the time, Soviet officials claimed she had been euthanized painlessly, a story that wasn’t corrected until decades later.
The mission itself was driven by political urgency. Soviet leader Nikita Khrushchev ordered the launch to coincide with the 40th anniversary of the Bolshevik Revolution, and engineers had only weeks to design and build the spacecraft. From the outset, many involved understood that the mission was a one-way trip.
Like human astronauts, Laika underwent rigorous training. She was confined in small cages, subjected to harnesses, and exposed to simulations that mimicked the conditions of spaceflight. These preparations were designed to measure how a living organism would respond to confinement, acceleration, and weightlessness.
On November 3, 1957, Laika was launched aboard Sputnik 2. Inside the cramped capsule, she was restrained by harnesses and surrounded by monitoring equipment tracking her vital signs. The environment was harsh and unnatural, and as the spacecraft orbited Earth, temperatures inside the cabin rose rapidly. Within hours, Laika succumbed to heat and stress.
Despite the tragedy, the Soviet Union initially portrayed the mission as a success. Sputnik 2 completed more than 2,500 orbits before eventually burning up in the atmosphere. However, those behind the program knew the cost of that achievement. Laika’s journey was never meant to bring her home.
Man’s best friend: beyond the laboratory
Laika’s story is heartbreaking partly because it stands in stark contrast to how we now see dogs: not just as test subjects, but as loyal companions, protectors, and healers. Dogs have walked alongside humans for thousands of years, helping us hunt, guard our homes, and more recently, support our health and independence. They truly are man’s best friends.
Today, dogs play a crucial role as guide dogs for people who are blind or visually impaired, giving them greater freedom to travel, work, and participate in everyday life. Research on guide dog ownership has found that blind owners often report better quality of life, increased mobility, and more social interaction thanks to their dogs. For many, that harness is more than a tool—it is a lifeline to the world beyond their front door.
Dogs are also increasingly recognized as powerful allies in mental health. Studies on therapy dogs and animal-assisted interventions have shown that interacting with trained dogs can reduce symptoms of depression, anxiety, and stress in various groups, including patients in clinical settings and university students under pressure. One systematic review of canine-assisted psychotherapy for young people found promising evidence that dogs integrated into therapy sessions can help reduce post-traumatic stress symptoms and improve communication with therapists. More recent work on dog-assisted therapy indicates that such programs can improve mood and overall quality of life during rehabilitation from illness.
Therapy dogs visit hospitals, aged-care homes, schools, and even workplaces, offering comfort to people who are lonely, grieving, or overwhelmed. For someone sitting alone in a waiting room or recovering in a hospital bed, the touch of a warm paw and the quiet presence of a dog can soften the edges of fear in ways that are hard to measure but easy to feel.
Stories of loyalty and love
Scientific studies help us understand dogs’ impact in numbers and graphs, but stories show us their impact in hearts and memories. One of the most famous is the tale of Hachikō, the faithful dog of Japan.
Hachiko was an Akita dog who lived with Professor Hidesaburō Ueno in Tokyo during the 1920s. Every morning, Hachiko would accompany Ueno to Shibuya Station and return in the afternoon to greet him as he stepped off the train. In 1925, the professor died suddenly while at work, but Hachiko continued to come to the station every day, waiting for his owner’s return. He kept this ritual for nearly ten years, through rain, snow, and heat, becoming a quiet fixture on the platform.
At first, commuters thought he was just a stray, but a 1932 newspaper article about his loyalty captured the nation’s attention. Eventually, a bronze statue of Hachiko was erected outside Shibuya Station, with the dog himself present at the unveiling. Although the original statue was melted down during World War II, it was later replaced, and today Hachiko remains a beloved symbol of loyalty, featured in films, books, and public art across Japan and beyond.
Hachikō’s story is not unique; it echoes countless quieter tales of dogs who wait at hospital doors, sleep beside children’s beds, or refuse to leave their owner’s graves. Around the world, guide dogs gently lead their partners across busy intersections, therapy dogs curl up at the feet of those in distress, and family pets rush to the door every evening when they hear familiar footsteps. Each of these moments, small as they may seem, adds to the case that dogs are no longer just animals—they are indispensable companions woven into the fabric of human life.
Laika’s legacy in a more compassionate world
Thinking about Laika against this backdrop of loyalty and care makes her story even more poignant. She was a stray who once wandered the streets of Moscow, likely scavenging for food and surviving from day to day, before being chosen for a mission humans themselves were not yet brave—or expendable—enough to attempt. In another life, she might have become a family pet, a child’s confidant, or even a therapy dog offering comfort instead of being sent into silence among the stars.
The world did not let Laika’s fate pass unnoticed. Over time, she came to be seen not just as a symbol of progress, but also as a reminder of the ethical responsibilities that come with scientific ambition. Her image appeared on stamps, in songs, and on products bearing her name, and discussions about her mission helped fuel broader debates about animal welfare in research. As our understanding of dogs deepened—through both emotional stories and clinical studies—so did our sense that their loyalty and sensitivity demand our respect.
In many ways, Laika represents the difficult beginning of humanity’s transition from Earth-bound beings to explorers of the cosmos, while Hachiko and countless therapy and guide dogs represent the best of what happens when that exploration is guided by compassion. As we continue to reach for the stars, these dogs remind us that true progress is not only about how far we can travel, but also about how gently we treat those who travel beside us.
