Company Background Information

Overview
We make microgravity accessible for research and industry. Tumbleweed was born out of a simple frustration: space is full of potential, yet almost impossible to use. We've been building space systems for years, including early work on wind-driven Mars rovers through Tumbleweed Mars. These projects shaped our engineering approach and highlighted a broader challenge: access to space is not limited by ideas, but by execution. As our expertise grew, we saw a critical need closer to home. Researchers and manufacturers are eager to leverage the benefits of microgravity, but the journey to orbit remains slow, bureaucratic, and prohibitively expensive. We experienced first-hand that access to microgravity isn't limited by imagination and potential -- it's limited by logistics.
