Radian One

Take off. Land.

Radian One is the world’s first crewed, single-stage to orbit vehicle with runway-like takeoff and landing. Our fully reusable, aircraft-like configuration requires far less infrastructure than vertical launch systems and can be reflown within 48 hours.
Flight Profile

Sled-assist takeoff

Radian One takes off subsonically with full propellant tanks.

Comfortable ascent

Low-G ascent for safe crew flight to LEO.

Flexible orbital operations

Missions range from once around to 5 days on orbit.

Reentry and landing

Wings allow smooth landing on any 10,000ft runway

Rapid reflight

Landing to launch times as fast as 48 hours.

Radian is developing one of the most important space vehicles I’ve seen to date. Building a responsive, single stage to orbit space vehicle that can take-off and land from existing runway infrastructure is a game-changer.

On demand space operations is a growing economy, and I believe Radian’s technology can deliver on the right-sized, high-cadence operations that the market opportunity is showing.

Dylan Taylor

Chairman and CEO of Voyager Space

Mix decades of experience with world-class talent and no pre-scheduled miracles - the Radian Aerospace team and its Radian One system are creating a new era of spaceflight.

Col. (ret) Bob Hodgkiss
