About World View

World View® is pioneering a new frontier at the edge of space and leading the way in the emerging stratospheric economy.

As an active, full-service commercial launch provider, World View’s technology is already opening up new realms of possibility for commercial customers around the world.

World View’s disruptive Stratollite flight platform enables previously unthinkable applications at a fraction of the cost of existing technology. Stratollites serve a variety of mission functions – from short duration research flights to long-duration flights over specific areas of interest – and serve a broad range of critical commercial needs and applications.

World View is led by experts in high-altitude ballooning, veterans of human spaceflight, and a team of retired NASA Astronauts, with a flight platform that is rooted deeply in technologies that have been successfully and safely used for decades.

When we saw Earth rising in the distance … it made us realize we all exist on one small globe.
