Radian Aerospace has hit a major milestone in developing the world's first fully reusable horizontal takeoff and landing orbital spaceplane, Radian One. Here's what you need to know about this game-changing vehicle.
On January 19, Washington-based Radian Aerospace announced it raised $27.5 million in seed funding, led by Fine Structure Ventures. Key investors including Exor, The Venture Collective, Helios Capital, SpaceFund, and The Private Shares Fund also joined, per company representatives. These funds will accelerate development of Radian One, a crewed orbital spaceplane.
The commercial launch market opportunity is valued at $200 billion, drawing significant investor interest.
Radian One stands out with its ability to launch and land horizontally on a runway, unlike NASA's Space Shuttle, which required solid rocket boosters for liftoff. It will use runway acceleration assistance for takeoff.
Fully reusable, Radian One can stay in orbit for up to five days. The company targets a rapid 48-hour turnaround after landing.
Details like vehicle size, passenger capacity, and first flight timeline remain undisclosed. However, Radian has secured launch service agreements with private firms and government agencies, though names weren't revealed.
“We believe widespread access to space unlocks unlimited opportunities for humanity,” said Radian CEO and co-founder Richard Humphrey. “Over time, we aim to make space travel as routine and convenient as air travel.”
Beyond tourism, missions will include point-to-point cargo delivery. Radian One can transport up to 2.2 tons of payload in under an hour nearly anywhere on Earth—a capability rivaling SpaceX's Starship but tailored for efficiency.
