A 21st century renaissance in high altitude ballooning

Bookmark and Share

High altitude ballooning has begun to undergo a renaissance that is creating exciting new capabilities, therefore enabling a wide array of new applications of interest to researchers and entrepreneurs in many fields. These new capabilities are breathtaking in both their scope and their expected impact. They include:

  • Station-keeping. This is the ability to place balloon platforms over a narrowly-define location, rather than being forced to drift away due to winds.
  • Point-to-point flight. This enables balloons to transect a user’s defined flight path over the ground or through the atmosphere, further removing ballooning’s longstanding limitation of being tied to the mercy of atmospheric currents.
  • Routine long-duration flight. Whereas most high altitude ballooning has been limited to flights lasting just a fraction of a day, with only rare, nearly heroic efforts being needed to mount long duration flights, affordable capabilities are now enabling flights of weeks and even months to become routine.
  • Onboard personnel. Systems that allow people to cost effectively fly at high altitude are now on the drawing boards and are expected to take flight within a few years, offering to lower many kinds of experiment costs as automation is avoided, and opening up stratospheric ballooning to commercial tourism.
  • Advanced balloon manufacturing. Whereas high altitude ballooning has always been limited by the intensive, hand labor nature of balloon construction, the application of artificial intelligence and other advanced manufacturing techniques now promise orders of magnitude increases in balloon production rates, enabling worldwide flight volume to soon grow from dozens to thousands per year.
Our missions are to pioneer and then apply new technologies that open the stratosphere up to commercial applications in the same way that satellites opened low Earth orbit and geostationary orbit to commerce.

Each of these capabilities is individually revolutionary. But the combination of these many revolutionary capabilities coming on line almost simultaneously is opening an almost dizzying array of new high altitude ballooning uses and markets. We can only barely imagine what will develop over the next decade or two, but we already foresee new high altitude balloon applications that include commercial, scientific, civil, and defense applications, such as:

  • Communications applications that range from arctic shipping and air commerce where geostationary communications satellites are disadvantaged, to critically needed voice, data, and commercial services above weather, earthquake, and fire disaster locales experiencing infrastructure outages.
  • Science applications that enable dense atmospheric monitoring to improve weather and crop forecasts, new kinds of long-duration astronomical observations at a fraction of the cost of satellite systems, and wide area, high resolution oceanographic capabilities that neither satellites nor buoys allow.
  • Edge of space tourism that offers longer flight experiences for just a fraction of the cost of a rocket ride, and does so without the rigorous training or understandable safety concerns of riding on rockets.
  • Technology demonstrations that allow the routine testing of sensors and experimental techniques at high altitude before they are sent to orbit, giving sensor developers the twin advantages of early risk reduction and competitive leverage.
  • Surveillance applications that range from crop and traffic monitoring, to drug and border enforcement, to defense and domestic security.

The high altitude ballooning company World View, where I am involved, is one of a number of companies that are developing and applying the new ballooning capabilities to open new markets in the high altitude of the stratosphere. World View was formed by entrepreneur technologists Jane Poynter and Taber McCallum, former Space Shuttle commander Mark Kelly, and myself. Our missions are to pioneer and then apply new technologies that open the stratosphere up to commercial applications in the same way that satellites opened low Earth orbit and geostationary orbit to commerce, and to offer flight services that are open the black sky and curved Earth experience to a much broader range of individuals than can withstand or afford suborbital tourism.

We consider ourselves pioneers in 21st century ballooning, but we are not the only such pioneers. We are joined in commercial high altitude ballooning by Google’s Loon, Near Space Corporation, and Zero2infinity. Soon, we expect, even more firms will enter this market. With so much going for it, the future of high altitude ballooning is as bright and this new century is young.
