Taber MacCallum
Founder, C0-CEO & Chief Technology Officer

Mr. MacCallum is Chairman of the Board of the Commercial Spaceflight Federation, whose mission is to advance commercial human spaceflight and the entire commercial space industry, to pursue ever-higher levels of safety, and share best practices and expertise throughout the industry. 

Taber MacCallum is co-founder and founding Chief Technology Officer (CTO) of World View Enterprises Inc., the world’s first fully integrated stratospheric ballooning company, locating manufacturing, vehicle integration, test, launch, operations and recovery together in a purpose-built facility. Under Taber’s technical leadership World View pioneered a new class of solar powered long duration stratospheric vehicle called a Stratollite. The stratospheric balloon technology uses regenerative air ballast for buoyancy and trajectory control to offer unique perspectives of Earth from the edge of space. The Silicon Valley-backed company offers enterprise and government agencies low-cost, long-duration, persistent high-altitude flight, unavailable by any other means. Stratollite applications include: communications in remote locations to connect the remaining 4-billiion people without reliable connectivity; remote sensing applications that DARPA has called “game changing;” weather insights that can increase tornado predictions from minutes to hours; and many research applications. The Stratollite was featured on the cover of the most widely read aerospace journal, Aerospace America. Working with Pima County, World View founded and operates Spaceport Tucson.

Prior to World View, he was the co-founder, CEO and CTO of Paragon Space Development Corporation, a leading designer and manufacturer of hazardous environment life support equipment. He also served as the CTO and safety officer for StratEx, a project that launched Google Executive Alan Eustace to the edge of space under a helium balloon for his world record-breaking flight in 2014, after which he dove back to Earth from over 135,000 feet, breaking the speed of sound. Technical innovations included stratospheric balloon launch systems, transonic flight stabilization, and the first newly designed operational space suit to fly in 40 years. The space suit is now on permanent exhibit at the Smithsonian National Air and Space Museum. A documentary called 14 minutes from Earth on the StratEx team and the extraordinary engineering and human feat was published in 2016.

Mr. MacCallum is a founding member of the Biosphere 2 design team, and one of eight original crew members that spent two years inside the materially sealed three-acre ecological system, which demonstrated the viability of artificial biospheres for use on Earth and in long-duration interplanetary travel.

Taber has sailed to over 40 ports and more than 30,000 miles around the world, serving at every level of command. He is an Advanced Diving Instructor and served as Dive Master on projects including reintroduction of captive research dolphins to the wild, ship salvage operations, Biosphere 2 Ocean collections, and deep-water specimen collecting expeditions in every ocean and most of the world’s seas.

Mr. MacCallum was the Principal Investigator on five space microgravity experiments starting in 1988 on the Soviet BioSatellite, then the U.S. Space Shuttle, Russian Mir Space Station and International Space Station. The four-month experiments on Mir produced the first animals to have completed their life cycle off the Earth.

He also served as Chief Technology Officer for Inspiration Mars, which detailed plans for an almost 2-year fly-by mission around Mars with two crew members, and published performance data from a complete life support system, demonstrating recycling of wastewater and oxygen.

Mr. MacCallum holds a variety of technology patents, most notably including Biosphere 2’s Atmospheric Monitoring System, the Boeing CST-100 spacecraft Humidity Control System, thermal radiators for Sierra Nevada’s Dream Chaser spacecraft, a hazardous water diving suit for the U.S Navy, the StratEx stable supersonic flight spacesuit, a waste water recovery system for Mars now going to the International Space Station, the World View stratospheric parafoil flight system, and several in breakthrough stratospheric altitude control navigation technology for the World View Stratollite.
