Sierra Space, a proven Defense Tech company delivering solutions for the nation’s most critical missions and advancing the future of security in space, announced today that its Dream Chaser® spaceplane has successfully completed a series of critical pre-flight tests at NASA’s Kennedy Space Center (KSC), marking continued progress toward Dream Chaser’s first free-flyer mission.

As part of its comprehensive testing campaign, Dream Chaser underwent Electromagnetic Interference and Electromagnetic Compatibility (EMI/EMC) testing at NASA’s Space Systems Processing Facility (SSPF). These tests verified the spacecraft’s ability to operate within expected electromagnetic environments throughout various missions.

The spacecraft also completed rigorous tow testing at KSC and Space Florida’s Launch and Landing Facility. For this phase, a Freightliner Cascadia truck, provided by Daimler Truck North America, towed the spaceplane at high speeds to simulate critical dynamics and validating autonomous navigational parameters during runway landing operations.

Additionally, Dream Chaser successfully demonstrated the ability to receive telemetry and distribute commands between the spacecraft and Mission Control in Louisville, Colorado over NASA’s Tracking and Data Relay Satellite System network. This key milestone tested the spacecraft’s readiness for real-time command and control during flight operations.

The testing campaign concluded with a post landing recovery rehearsal, which demonstrated the safing of vehicle systems and timely access to sensitive payloads.

With these critical milestones achieved, we expect Dream Chaser to move to its final round of acoustic testing in December 2025. Following this, modifications for national security applications will be explored and performed in Colorado. These enhancements will aim to expand Dream Chaser’s versatility and demonstrate its ability to fulfill a wide array of mission requirements, including those essential to national defense.

Dream Chaser is on track for its first launch to Low Earth Orbit, targeted in Q4 of 2026, through a demonstration mission under the CRS-2 contract with a runway landing at Vandenberg Space Force Base.

“Each milestone we achieve is a testament to the resilience, innovation and dedication of the Sierra Space team, and represents another significant step forward in ensuring Dream Chaser’s success as a versatile, reusable spacecraft,” said Fatih Ozmen, Executive Chair at Sierra Space. “We are excited to see Dream Chaser progressing steadily toward its inaugural flight to support the nation’s most pressing space priorities.”

Sierra Space is committed to advancing the future of space transportation, exploration, and defense, delivering innovative solutions that safeguard national security and ensure freedom of operations beyond Earth.
