Which Countries Have Sent People Into Space?

More than 50,000 events are planned across more than 100 countries as World Space Week begins with celebrations focused on space technology and exploration, news.un.org reported. This year marks sixty-nine years since the Soviet Union launched Sputnik 1 on October 4, 1957, opening the Space Age and setting off a race with the United States. Al Jazeera reported that the annual observance runs through October 10, commemorating the date in 1967 when the Outer Space Treaty came into force to establish that space should be explored peacefully and claimed by no single nation.

Indian space centres organize rocket revolution events

Events span international space agencies, schools, museums, and astronomy clubs, featuring stargazing nights, science classes, exhibitions, and talks by astronauts and scientists. In Kerala, India, Indian Space Research Organisation (ISRO) centres including the Vikram Sarabhai Space Centre, the Liquid Propulsion Systems Centre, the ISRO Inertial Systems Unit, and the Indian Institute of Space Science and Technology are jointly organizing celebrations under the theme “Rocket Revolution,” The Hindu reported. The program features interactive lectures, student presentations through the ‘Your Space’ program, public outreach events at the Kerala State Science and Technology Museum, and a sounding rocket launch at TERLS, VSSC.

Similarly, the Oman Society of Astronomy and Space is organizing astronomical observations and educational workshops under the same “Rocket Revolution” theme to highlight rapid advancements in launch technologies, Shahad bint Rashid Al Hosni, Deputy Chairperson of the Space Sciences Committee at the organization, told the Times of Oman. The United Nations observes the week from October 4 to 10 to celebrate space technology contributions to humanity, noting that the current theme focuses on how reaching space is transforming through commercial launch providers, reusable rockets, and university teams, according to news.un.org.

Behind these celebrations sits a stark demographic reality in human spaceflight. At least 746 people from over 50 countries have travelled to space, including professional astronauts and paying tourists, Al Jazeera reported. China has sent 29.

Commercial flights drive rising female space travel

Space remains a male-dominated frontier, with women comprising only 15 percent—or 112 out of 746—of all space travellers, Al Jazeera reported. Soviet astronaut Valentina Tereshkova became the first woman in space in June 1963, while the United States did not send a woman until Sally Ride flew in June 1983. However, the share of female space travellers is rising due to commercial flights, with more than half of the women who have flown since 2020 going up as paying passengers or guests on Blue Origin’s suborbital rocket, according to Al Jazeera data.

Commercial flights have also widened the age range of space travellers. While most people have flown in their 30s or 40s—accounting for 85 percent with a median age of 40—extremes have emerged recently, Al Jazeera reported.

The technological evolution spans from Sputnik 1 to modern reusable launch systems like SpaceX’s Starship and India’s Polar Satellite Launch Vehicle, Moneycontrol.com reported. Reusable boosters are designed to lower launch costs and increase flight frequency. Meanwhile, United Nations entities utilize space science for terrestrial applications, such as the International Atomic Energy Agency and the Food and Agriculture Organization sending seeds to the International Space Station to test climate resilience, and the UN Environment Programme tracking 130 million pieces of space debris, news.un.org reported.
