Astronauts by top nations
The majority of astronauts (95%) have also reached the Kármán line at 100 km — the internationally recognized boundary of space.
Launch failures by number of satellites lost, 2003-2023
In 2023, launch failures resulted in the loss of 31 satellites, an increase of 48% from 2022.
Cumulative spacecraft on orbit, 1957-2023
Federal agencies in 2014 estimated by 2022 as many as 43 commercial satellites a year would head to orbit. Instead, more than 50 times . . .
Space insurance industry estimates, 2003-2022
As satellites get smaller and cheaper and companies pivot to building LEO constellations rather than purchasing single large satellites for GEO orbit, many operators are foregoing insurance after launch altogether.
Astronauts by private sector
As of mid-March, 685 astronauts have reached at least 80 kilometers above the Earth’s surface. This total includes 86 private astronauts, 22 times as many as there were two decades ago.
January, February launches 2022-2024
The first two months of 2024 saw an incredible pace of launches. The record set in 2023 could topple if two players alone make their goals.
Spacecraft deployed by payload type, 2021-2023
Commercial satellites accounted for 90% of space-craft launched in 2023, with communications satellite constellations leading the pack.
Vandenberg customer mission share 2014–2023
No single mission segment dominated the base’s launches until 2022, when 10 of 16 Vandenberg launches delivered commercial payloads to space.
Cumulative human spaceflight, 1961–March 18, 2024
Human spaceflight activity is off to a rapid pace in 2024 with a private Axiom mission, a public ISS mission, and a private Virgin Galactic mission taking flight in the first nine weeks of the year.
