23 innovative space startups you should know (2025)

What are space startups?

Space startups are using the latest technology to provide solutions that are applicable to space exploration, research, and travel, as well as collecting data that helps us expand our knowledge of space.

Vestigo Aerospace

Founded in 2020, Vestigo Aerospace makes “drag sails” to help clean up space junk in Earth’s orbit. All the broken satellite parts and unused rocket bodies circling the planet pose growing dangers. Vestigo’s dragsails provide a solution. Their lightweight sails attach to satellites and rocket upper stages that have reached the end of their mission. The drag sail opens up like a parachute increasing drag in space. This pulls space vehicles back into Earth’s atmosphere sooner to burn up, reducing orbital clutter.
