Haas (rocket)

Haas was a family of rocket space launchers developed by ARCAspace for the Google Lunar X Prize competition and for their national crewed space program. As of 2020 no rocket has been launched, the planned rocket types changed significantly over time.

It was named after Conrad Haas, a rocket pioneer who lived and worked in what is now Romania, and was the first person to describe a multistage rocket in writing.
