Atomos Space

Colorado startup that designed space tugs to tow satellites from rideshare drop-off points to higher orbits. Katalyst Space Technologies bought it in 2025. (1 product in the atlas)

Acquired by Katalyst Space Technologies (deal closed March 2025). Atomos ran a spacecraft factory in Broomfield, CO, which Katalyst said it would keep using. Atomos's own domain, atomos.space, is now parked, so the website link is an archived copy from January 2025.
