World View Enterprises is a Tucson-based company that specializes in high-altitude balloon flights for scientific research, commercial imaging, and other applications. The company was founded in 2013 by Jane Poynter and Taber MacCallum, who were also co-founders of the Biosphere 2 project. World View's balloons are designed to carry payloads up to the edge of space, where they can remain aloft for extended periods of time. The company has also developed a space tourism program, which aims to offer passengers a unique perspective on the Earth from the edge of space. World View has partnerships with several government agencies and private companies, and has conducted successful test flights of its balloon technology.
