The question of how many humans have reached space continues to spark public interest. As of late September 2025, ten people are currently orbiting Earth aboard the International Space Station, representing different space agencies from the United States, Russia, Europe, and Asia. Meanwhile, over six hundred individuals have made the journey beyond our planet since the dawn of human spaceflight more than six decades ago.

This figure highlights not only the remarkable progress achieved since Yuri Gagarin’s pioneering mission in 1961 but also the rapid expansion of access to space. From Cold War rivalries to today’s era of international cooperation and private industry involvement, the human presence beyond Earth has grown into a global phenomenon.

Expanding Human Presence in Space

The growth in the number of humans in space reflects a shift from exclusive government programs to broader participation that includes commercial missions. Initially dominated by the United States and the Soviet Union, human spaceflight is now shared by agencies such as ESA, JAXA, and even private firms like SpaceX and Blue Origin.

This transformation has redefined what it means to be an astronaut. Tourists, scientists, and international representatives are now part of the statistics, signaling a future where space travel could be as accessible as air travel one day.

Historical Milestones in Human Spaceflight

The first breakthrough occurred in April 1961, when Yuri Gagarin became the first human to orbit Earth. His journey lasted only 108 minutes but marked a defining moment in the history of exploration. Soon after, American astronaut Alan Shepard conducted a suborbital flight, followed by John Glenn, who became the first American to orbit Earth.

During the 1960s and 1970s, the space race reached its peak with Apollo missions, culminating in Neil Armstrong’s historic moon landing in 1969. These achievements cemented space exploration as a frontier of human ambition and technological prowess. The Soviet Union, meanwhile, pioneered long-duration missions aboard the Salyut and Mir space stations, laying the groundwork for today’s ISS operations.

The Role of the International Space Station

Launched in 1998, the International Space Station represents the largest and most enduring human outpost in orbit. It hosts astronauts continuously, serving as a laboratory for scientific research and a platform for testing new technologies. More than 250 people from nearly 20 nations have visited the ISS, making it the most internationally inclusive program in space history.

The station is also a symbol of post-Cold War cooperation, with contributions from NASA, Roscosmos, ESA, JAXA, and CSA. Despite political tensions on Earth, the ISS demonstrates how collaboration in space can bridge divides and advance knowledge for the benefit of all humanity.

How Many People Have Reached Space

According to the Fédération Aéronautique Internationale (FAI), which defines space as beginning at 100 kilometers above Earth, approximately 642 people have crossed this boundary as of 2025. If using the U.S. definition of 80 kilometers, the number rises slightly, due to the inclusion of additional suborbital flights.

The majority of these spacefarers are from the United States and Russia, accounting for nearly three-quarters of all astronauts and cosmonauts. China has emerged as a significant player since its first human spaceflight in 2003, sending more than twenty taikonauts into orbit.

National Contributions to Spaceflight

The United States leads with more than 350 astronauts, many of whom flew on Apollo, Space Shuttle, and ISS missions. Russia, continuing the legacy of the Soviet Union, has sent over 120 cosmonauts into orbit. China has gradually expanded its space program with the Tiangong space station and lunar exploration ambitions.

Beyond these superpowers, more than 40 countries have sent representatives into space. From Canada to Japan and from the United Arab Emirates to India, the diversity of human spacefarers underscores the global nature of exploration. European astronauts, in particular, have played vital roles in ISS operations and international science collaborations.

The Rise of Commercial Spaceflight

In the past decade, private companies have opened new pathways to space. SpaceX, through NASA’s Commercial Crew Program, regularly ferries astronauts to the ISS. Blue Origin and Virgin Galactic have also conducted suborbital flights, some carrying tourists who experienced a few minutes in microgravity.

This trend expands the pool of individuals who can legitimately claim to have traveled to space. Billionaires, scientists, and private citizens have all joined professional astronauts, raising questions about the future role of tourism in the broader exploration agenda. While critics argue that suborbital hops are not equivalent to orbital missions, supporters view them as vital in democratizing access to space.

What Lies Ahead for Humans in Space

The number of humans who have reached space is expected to increase rapidly in the coming years. Upcoming missions aim to establish permanent bases on the Moon, spearheaded by NASA’s Artemis program and China’s lunar initiatives. These missions will bring a new class of astronauts who will live and work beyond Earth’s orbit for extended periods.

Meanwhile, Mars exploration remains a long-term goal. SpaceX has publicly announced its ambition to transport humans to the Red Planet, potentially within the next decade. If realized, this would represent the most ambitious leap since the Apollo program and could significantly expand the statistics of humans in space.

Expert Perspectives on Future Growth

Space policy experts note that human spaceflight is entering a new phase characterized by international partnerships and commercial investments. “We are at the dawn of a new era where space is no longer the domain of a few nations but a shared human frontier,” said Dr. Laura Forczyk, a U.S.-based space analyst.

Economists also point to the growing space economy, which is projected to surpass one trillion dollars by 2040. As demand for satellite services, lunar mining, and orbital manufacturing grows, so too will the need for skilled astronauts and space professionals.

Public Fascination and Cultural Impact

The fascination with human spaceflight extends beyond statistics. Each new mission captures global attention, inspiring documentaries, films, and educational programs. The stories of astronauts serve as a reminder of human resilience and ambition, pushing the boundaries of what is possible.

Social media has amplified this fascination. Astronauts aboard the ISS share real-time images and videos, allowing millions to experience space vicariously. This direct connection with the public strengthens support for funding and sustains excitement for future missions.

The reality today is clear: ten people are currently orbiting Earth, and over six hundred have ventured into space since Gagarin’s first flight. The journey from Cold War rivalry to a diverse and increasingly commercialized landscape reflects humanity’s determination to expand its reach. With the Moon, Mars, and beyond on the horizon, the number of humans in space will continue to rise, shaping not just exploration but the very identity of our species.

Nonostante le prese di posizione anche più marcate e l’allargarsi del fronte degli stati che riconoscono lo stato palestinese, continua a mancare un’azione internazionale per fermare il genocidio a Gaza. E quindi le IDF non hanno motivo di interrompere i crimini di guerra. Il primo di cui scriviamo oggi è denunciato in un nuovo report dell’Euro-Med Human Rights Monitor. Sabato l’esercito israeliano ha assassinato 9 membri di una famiglia nella città di Gaza, nel campo profughi al–Shati. Dopo quasi due anni di aggressione di Gaza gli attacchi in cui vengono uccisi tutti o quasi tutti i membri di una famiglia non fanno più notizia, ma questo è un caso particolarmente allarmante: l’attacco è stato lanciato il giorno dopo che la famiglia aveva rifiutato una richiesta di collaborazione da parte delle IDF. Specificamente, i militari israeliani avevano chiesto di formare una milizia locale, che potesse compiere azioni illegali sul territorio nei pressi del campo profughi. L’accordo avrebbe probabilmente preso forma di una nuova milizia analoga alle Forze popolari di Yasser Abu Shabab, il gruppo miliziano sostenuto da Tel Aviv diventato famigerato per come regolarmente attacca i convogli che trasportano alimenti e aiuti umanitari — quando ci sono. Mentre scriviamo non è ancora chiaro se le persone sono le stesse che avevano ricevuto la proposta, e l’hanno rifiutata, o se sono stati uccisi loro familiari. Euro–Med denuncia quella che è a tutti gli effetti una politica ricattatoria, di coercizione: o si accetta di lavorare con i militari israeliani, o si viene uccisi: “Quella che era iniziata come una forma di estorsione individuale si è trasformata in una pratica sistematica e collettiva volta a smantellare il tessuto sociale palestinese, costringendo le persone a tradire le proprie comunità.” (Euro–Med Human Rights Monitor)
