US Space Plane Undergoes Quantum Test

The U.S. Space Force's unmanned orbiter, the X-37B, is preparing for its eighth mission. Developed by Boeing, the spacecraft will test quantum-based navigation systems and laser communication technologies, contributing to future deep space missions. The X-37B's new mission launches just six months after the successful OTV-7 mission.

The X-37B spaceplane is in preparation for launch at facilities at Kennedy Space Center in Florida, Boeing announced on July 28, 2025. The launch window is set for August 21, 2025, at the earliest.

The spaceplane for the OTV-8 mission will carry a service module, which will enable more experiments and open up new mission opportunities for partner organizations like the U.S. Air Force Research Laboratory and the Defense Innovation Unit.

Two critical technologies will be tested as part of the mission:

• High-bandwidth laser-based satellite communication systems

• The highest-performance quantum inertial sensor ever sent into space

Boeing officials stated that this sensor will enable precise positioning, navigation, and timing (PNT) in environments without GPS. This technology is particularly critical for navigation on deep space and lunar missions.

“The laser communications demonstration on the OTV-8 mission will be a significant step in the Space Force’s ability to utilize commercial space networks as part of a more diversified and resilient space architecture,” said General Chance Saltzman, Commander of U.S. Space Force Operations Command.

Location Detection Without GPS

It was emphasized that the quantum inertial sensor will offer a major technological advancement in location and orientation, particularly in environments where GPS is disabled. "This technology ensures the Space Force's mobility and freedom of maneuver," said Colonel Ramsey Hom, Commander of Space Delta 9.

4,200 Days of Orbital Experience

Since its first launch in 2010, the reusable X-37B spaceplane has spent more than 4,200 days in orbit. Developed by Boeing's Phantom Works unit, the X-37B plays a key role in testing next-generation orbital technologies for national security, scientific research, and future interplanetary missions.
