The United Nations has commemorated October 4 through 10 as World Space Week every year since 1999.
This period is also a time to reflect on how humanity uses space technology and who has been able to go into space.
Records in spaceflight have grown, but participation remains heavily concentrated in one direction.
3-Line Summary
1. World Space Week is October 4–10
2. 746 people from 52 countries have been to space
3. The numbers show disparities in access to space
The Meaning of October, from Sputnik in 1957
On October 4, 1957, the Soviet Union launched Sputnik 1, the first artificial satellite to orbit Earth. According to Al Jazeera, the launch is considered the beginning of the Space Age and led to the space race between the United States and the Soviet Union.
October 10 marks the date in 1967 when the Outer Space Treaty entered into force. Signed by the United States, the United Kingdom, and the Soviet Union, the treaty established the principle that space must be explored and used peacefully and that no country may claim space as territory. These two dates are the background to the United Nations’ decision to designate October 4 through 10 as World Space Week.
Events take many forms, including observation sessions, science classes, exhibitions, and lectures by astronauts and scientists. However, the central point this week highlights is not the commemoration itself, but that space activities are already connected to life on Earth through communications, location information, and weather observation.
A Record of 746 People, Distributed Across 52 Countries
Al Jazeera counted 746 people from at least 52 countries as having been to space, using the Kármán line—in other words, the standard that regards 100 km above the ground as the boundary of space. The figure includes not only professional astronauts but also passengers who paid to fly. Because some people hold dual citizenship and others flew on behalf of countries that no longer exist, nationality figures are difficult to read as a simple table of national competition.
The proportions by country are clear. The number of people from the United States was given as 369, while the combined number from the Soviet Union and Russia was 138. China was the third country to conduct crewed spaceflight using its own rockets, and the number of Chinese space travelers was counted at 29.
The gender gap also remains. Of the 746 people, 112 were women, or about 15%. The first woman astronaut was Soviet cosmonaut Valentina Tereshkova, who flew in 1963, followed by American Sally Ride in 1983. These figures show that the fact that more people have gone into space and the assessment that opportunities for spaceflight have expanded evenly are not the same thing.
Lower Launch Costs Are a Possibility, Not a Guarantee
The Economic Times reported that the cost of placing 1 kg of an artificial satellite into orbit fell from approximately 8만7,023 dollars in 1960 to 3,868 dollars in 2025. The figures are also represented by the numeric tokens 7023 and 3868. Reusable rockets, which recover, inspect, and reuse major launch-vehicle components, were introduced as one background factor in the change in costs.
If launches become easier, there may be more room to put into orbit satellites used for communications, navigation, weather observation, and disaster monitoring, including wildfires and floods. However, a decline in launch costs does not mean that the entire satellite business is inexpensive or that profitability is guaranteed. Satellite development and maintenance still require substantial costs, while space debris, geopolitical issues, and dependence on particular launch services remain variables.
Cost projections for 2030 and 2040 are only estimates introduced by The Economic Times, not confirmed results. During World Space Week, the numbers that deserve more attention may be the current records showing who is already using space technology, and under what conditions, rather than forecasts of the future.
