Where things stand
As of 27 September 2026
Nearly half the companies in the directory are American. Nine US companies have grown past the startup stage, most of them by going public. SpaceX listed on Nasdaq in June 2026, in the largest IPO in history. Firefly Aerospace listed in August 2025, five months after its Blue Ghost lander made the first fully successful commercial Moon landing. Hawkeye 360 listed on the New York Stock Exchange in May 2026.
Several US companies founded since 2020 flew hardware in the past year. Impulse Space brought two of its Mira vehicles within about 200 metres of each other in July 2026. K2 Space launched Gravitas, a satellite of about two tonnes, in March 2026. Starcloud put an Nvidia H100 data-centre GPU in orbit in November 2025. Katalyst Space launched LINK, its first servicing spacecraft, in July 2026. Two of its three reaction wheels then failed, and NASA and Katalyst dropped the planned capture of the Swift observatory.
Eighteen US companies have been bought. Voyager Technologies bought Astrobotic in July 2026. York Space Systems bought Solestial, and its parent company bought Atlas Space. IonQ, a quantum computing company, bought Capella Space in 2025. Six US companies have shut down and ten are dormant. Moon Express is one of the dormant ones. It has had no documented activity since November 2018, when NASA named it one of nine companies to carry payloads to the Moon.
