Six decades of global human spaceflight participation (1961–2026) — who has flown, from where, for how long, and how the mix has shifted from the Space Race to the commercial era.
Drawing upon Jonathan C. McDowell's General Catalogue of Astronauts, this census analyses 773 of the catalogue's 783 flown astronauts (1961–2026); the 10 still in space when the snapshot was taken have no completed career duration and are excluded. Four key structural stories emerge from the data:
With 199 debuts and counting, the 2020s is already the busiest maiden-flight decade in history, surpassing the 1990s ISS construction peak (168 debuts).
USA (460 flyers) emphasizes headcount breadth (median career 19.8 days). Russia (131 flyers) emphasizes long-duration station endurance (median 194.8 days, record 1,110.6 d). China (27 flyers) maintains deliberate 6-month Tiangong increments (median 192.2 days).
82.4% (637) achieved orbit, while 17.6% (136) flew suborbital only. 123 of the 136 suborbital flyers first flew in 2021 or later, on commercial vehicles (Blue Origin & Virgin Galactic); the other 13 are X-15, SpaceShipOne and Virgin Galactic test pilots and crew (1962–2019). Russia and China have 0 suborbital flyers.
Women represent 14.7% (114/773) of all human spacefarers. The proportion has grown from 8.5% in the 1980s to 25.1% in the 2020s, but remains far below parity.
Two eras in one chart. For six decades almost everyone who "went to space" reached orbit; since 2021 a wave of suborbital passengers (Blue Origin, Virgin Galactic) has redefined the astronaut count. An astronaut is counted Suborbital only if they never reached orbit. This panel always shows both classes; the Flight filter above drives every other chart.
Each person is counted in the year of their first flight. Bars are stacked by citizenship group. Drag the slider under the chart to zoom into an era; the 2021→ spike is suborbital commercial spaceflight.
The original study figure, rebuilt interactively: number of astronauts per first-flight year, split by how long they have cumulatively spent in space. One panel per country; colour runs short→long.
Box & whisker of total career duration (days, log scale) per astronaut. Russia's median dwarfs everyone — a long-duration station legacy.
The same measure, grouped by the decade of first flight. The spread widens as both ultra-short tourist hops and year-long station stays appear.
Headcount of everyone who has flown, all years combined.
Share of each country's astronauts falling in each duration band (100% stacked).
Width of each ribbon is the number of astronauts flowing from a country into a duration band.
Chords link decades to the countries that debuted astronauts in them. Arc length is total debuts.
A force-directed bipartite graph: countries (squares) linked to the decades (circles) in which they sent people up. Edge thickness = number of debuts; drag nodes to explore.
Each country's normalised fingerprint across the five duration bands — the shape shows a national spaceflight "style".
Density of astronaut debuts across decade and duration band.
New male vs. female astronauts per year. The female share climbs but has never reached parity.
