OUR BALLOON
HIGH-ALTITUDE INNOVATION
Redefining Stratospheric Access
Leveraging decades of experience and over 20 patents, our Microballoons™ (mHABs) represent the most effective and forward-looking approach to harnessing the full potential of the stratosphere. The mHAB offers rapid (5 minute); high-wind launch capabilities, unprecedented durability, balloon navigation and persistence via patented altitude control systems, reliable and redundant actuated termination, and unprecedented affordability. Swarms of mHABs can be launched and operated by a single user from virtually anywhere. As a payload-agnostic platform, the mHAB is only constrained by the creativity of its users.
