Efforts to launch commercial space flights from Abu Dhabi are accelerating rapidly. Seattle-based Radian Aerospace displayed a model of its revolutionary Radian One spaceplane at the Global Aerospace Summit in Abu Dhabi, unveiling a fully reusable vehicle designed for horizontal takeoff and vertical landing — capable of carrying passengers and cargo to low Earth orbit.
Radian One: A New Approach to Reaching Space
Unlike conventional rockets, the Radian One spaceplane eliminates the need for a disposable carrier rocket entirely. Instead, it uses a rocket-powered rail sledge system to accelerate the vehicle along a runway before it fires its own engines and climbs to orbit. The spaceplane is designed to operate at altitudes exceeding 400 km and can carry up to 2,270 kg of cargo to orbit, returning with as much as 4,540 kg on descent.
Radian's goal is a suborbital test flight by 2028, followed by an orbital test flight in 2029, with commercial operations beginning shortly after.
Why Radian Aerospace Chose Abu Dhabi
Livingston L. Holder, co-founder and CTO of Radian Aerospace — and a former military astronaut — explained why the UAE was selected for early testing. The UAE's adaptable regulatory environment and cost-effective infrastructure made Abu Dhabi the ideal location to conduct flight tests quickly and affordably.
"We were able to construct and conduct the necessary flight tests on our vehicle much sooner and without straining the UAE's financial capacity," Holder said.
The company has been conducting taxi tests of its prototype, designated PFV01, at a small airfield in Abu Dhabi. The five-meter carbon fiber vehicle reached Mach 0.7 in ground runs, validating its aerodynamic handling ahead of true flight tests.
A Strategic Hub for the New Space Economy
What distinguishes the Radian One from other space tourism concepts is its versatility. The spaceplane can dock with the International Space Station or private orbital outposts, making it suitable for both crewed missions and cargo resupply — not just point-to-point tourism.
CEO Richard Humphrey has pointed to this capability directly: "We think Starship is going to deliver space stations to low Earth orbit, and we're going to resupply them with people and stuff."
With ground tests underway and a clear commercial roadmap, Abu Dhabi is positioning itself as a strategic center in the rapidly growing global space economy — and Radian Aerospace is betting that the UAE's forward-looking approach will help get it there first.
