Sierra Space's Dream Chaser is targeting a mid-2026 launch to become the first winged spacecraft to land on a runway since the Space Shuttle Atlantis in 2011.
Sierra Nevada's Dream Chaser traces its aerodynamic DNA to NASA's 1960s lifting body research at Edwards AFB, built to land on a runway like a conventional aircraft.
The X-15 set the all-time air speed record of Mach 6.72 in 1967, and its thermal, control, and reentry data directly shaped Apollo, the Space Shuttle, and every hypersonic vehicle in development today.
The Air Force's X-20 Dyna-Soar was a pilot-flown reusable orbital spacecraft canceled in 1963 - and its engineering legacy directly shaped the Space Shuttle, X-37B, and Dream Chaser.
Sierra Space's Dream Chaser traces its runway-landing design to 1960s Edwards AFB lifting body research, representing over 60 years of aerodynamic reentry development.
