The U.S. Space Force’s secretive X-37B spaceplane is set for its eighth mission on Aug. 21 from Kennedy Space Center, launching atop a SpaceX Falcon 9 rocket.

The uncrewed, reusable spacecraft, built by Boeing, conducts technology tests and experiments in orbit, often staying in space for 12–24 months.

This mission will focus on laser-based inter-satellite communications and advanced quantum navigation, allowing the craft to operate without GPS.

Since 2010, the X-37B has spent over 4,200 days in orbit and traveled more than 1.3 billion miles, landing like a plane after completing missions, ABC News has reported.

Space Force emphasizes the project’s role in enhancing resilience, security, and innovation for U.S. orbital operations.
