Sierra Space has received major regulatory approval for Dream Chaser, bringing its long-delayed spaceplane closer to its first orbital flight. The Federal Aviation Administration (FAA) has allowed the spacecraft to return from orbit and land at Vandenberg Space Force Base in California.
The approval affects a critical part of Dream Chaser’s flight operations. The first mission will launch from Florida aboard United Launch Alliance’s Vulcan Centaur rocket. The spacecraft will then fly back through Earth’s atmosphere before landing on a conventional runway.
Vandenberg becomes the primary landing site
The FAA issued Dream Chaser’s vehicle operator’s license on November 9th. Sierra Space confirmed the approval the following day. The five-year license allows up to four re-entries per year with an unchanged vehicle configuration and mission profile.
Vandenberg now serves as the designated landing site for the spacecraft. This represents a change from Sierra Space’s original plans. During an environmental review in 2024, the company identified the former Kennedy Space Center runway as a preferred landing site.
Vandenberg initially appeared as a backup option. The newly issued license instead identifies the California facility as Dream Chaser’s landing destination.
The agreement also gives Sierra Space an approved runway for its first flight. However, the FAA approval does not specify a launch date. Mission timing still depends on the availability of a Vulcan Centaur rocket.
Tenacity is bringing back cargo
Dream Chaser’s first spacecraft, Tenacity, combines a lifting body design with folding wings. The configuration allows it to fit into Vulcan’s payload fairing during launch. In orbit, the spacecraft can carry about 12,100 pounds of cargo.
According to the FAA’s environmental impact assessment, the return capacity reaches 4,080 pounds. This capability eliminates an important limitation of conventional cargo spacecraft.
Capsules typically return via parachute landings, often requiring recovery at sea. Dream Chaser offers a runway landing instead. According to Sierra Space, the returning cargo experiences less than 1.5 times Earth’s gravity during the journey.
The company also claims that the spacecraft can use runways designed to accommodate Boeing 737 aircraft. This flexibility could benefit experiments and sensitive equipment that requires careful handling after landing.
NASA mission goes in a new direction
The Dream Chaser spaceplane originally participated in NASA’s commercial resupply program in 2016. Sierra Space secured a contract to develop the spacecraft for cargo deliveries to the International Space Station.
Repeated development delays and problems with the propulsion system further delayed the debut. NASA and Sierra Space finally revised their agreement in September 2025.
The revised plan removed the space station docking requirement from Dream Chaser’s initial demonstration. Tenacity will instead conduct an independent free-flying mission in orbit.
NASA can continue to acquire resupply missions if the demonstration is successful. Sierra Space also has national security and commercial customers signed up for the first flight.
In September, the company confirmed that these customers would contribute payloads in addition to NASA cargo. However, neither their identity nor the specific equipment planned for the launch have been revealed.
Sierra Space originally planned the first mission at the end of 2026. The company has tied this schedule to the availability of Vulcan Centaur. As the year nears its end, the launch window remains uncertain.
The FAA’s approval removes another regulatory hurdle. Tenacity still needs its launch vehicle and remaining mission preparations before returning to the runway becomes a reality.
