Interactive Tables and Charts
Launch Attempts and Deployed Payloads, 1983-2022
Two items stand out as primary examples of astronomers’ concerns: the SpaceX Starlink constellation due to its number of satellites and AST SpaceMobile’s BlueWalker 3 satellite due to its size — 693 square feet6 — which ranks as the largest commercial communications array in space.
Launch Failure Rate 2019-2023
The frenetic pace of launch in 2023 also brought a higher number of launch failures, with 11 rockets failing to make orbit, of them in spectacular fashion.
Launch Attempts by Country and Category, 2023
The United States launched 11 military missions in the year, including payloads for the National Reconnaissance Office and a new generation of small communications satellites for the Space Development Agency. Russia launched 10 civil government missions in 2023, including Soyuz launches to send crews to the International Space Station, which remains one area of cooperation between the Kremlin and NASA. India made headlines with its successful launch of a lunar probe while the European Space Agency, awaiting its new Ariane-6 launch vehicle, launched three spacecraft including its Euclid space observatory.
Launch Attempts by Category, 2014-2023
Commercial launches represented 54% of all 2023 launches. Over the past decade, the number of commercial launches has seen a six-fold increase while military and civil government missions have stayed comparatively flat.
Launch Attempts by Select Nations, 2022-2023
The record number of launches came despite delays that pushed the debuts of several long-anticipated launch vehicles into 2024. It was the third consecutive year to shatter launch records, despite a decline in European and Russian launches.
Orbital Launch Attempts, 1957-2023
The number of U.S. launch at- tempts climbed from 87 in 2022 to 116 last year. The number of U.S. launches has more than doubled since 2021, which saw 51 launch attempts.
Leap Second Adjustments to UTC, Navigation Satellites, 1972-2023
But every technological leap in clock accuracy can’t overcome the wobbly planet’s ability to throw off timing standards. Using leap seconds, the International Bureau of Weights and Measures has changed clocks to match the astronomical time on Earth 27 times.
Total Spacecraft by Mission Segment, 2020-2023
The number of satellites in all three mission segments grew by double digits in 2023, with civil government payloads growing most rapidly (74% year-over-year). Over the past four years, the size of all mission segments has more than doubled. Commercial payloads once again made up the largest proportion of deployments in 2023 thanks to mega-constellations such as Starlink.
Japanese Launch Attempts, 2013-2023
One problem area for Japan is the possibility of a gap in reliable access to space. The nation is one of 10 capable of orbital launch, but its launch activity is relativity infrequent.
Japanese Workforce by Sector, 2005-2021
JAXA employed 1,580 individuals at the beginning of 2023. Out of this total, 1,123 (71%) are engineering and research employees. Even though Japan as a whole is struggling with an aging population, JAXA’s age demographics are more normally distributed than many other nation’s space agencies.
