Dream Chaser
The First-Ever Winged Commercial Spaceplane
- Capable of gentle 1.5G runway landings, ideal for precious cargo, especially human passengers.
- Accommodates more than 12,000 pounds of supplies and equipment.
- NASA resupply missions for the International Space Station begin in 2023.
- Configuration intended for up to seven crewmembers, plus critical supplies.
- Compatible with a wide array of current and future launch vehicles.

Sierra Space expands spaceplane fleet with in-house mission control, 2024-11-08.
- The long-awaited inaugural cargo flight of Sierra Space’s Dream Chaser spaceplane has been delayed to no earlier than May 2025.
- Sierra Space is moving forward with its second cargo spaceplane, Reverence, alongside work on an array of inflatable habitats and other structures to meet growing demand for in-space infrastructure.
- Adjacent to the factory floor, Sierra Space’s new, in-house mission control center will support Dream Chaser operations.
Is the Dream Chaser space plane ever going to launch into orbit? Eric Berger, 2025-08-04.
- "They're in final assembly," she said of Sierra Space. "They're doing a lot of tests, and they're doing what I call final certification work.
- Some of the big key areas that they're focused on is the software certification. You've got to test end-to-end all the different software functions.
- The company had planned to fly the vehicle close enough to the space station such that it could be captured and berthed to the orbiting laboratory.
- One option now under consideration is a mission that would bring Dream Chaser close enough to the station to test key elements of the vehicle in flight but not have it berth.
- It appears highly unlikely that Dream Chaser will be ready for its debut spaceflight this year for these technical reasons. Another challenge is the availability of its Vulcan launch vehicle.

LIFE Habitat (Large Integrated Flexible Environment)
Plans to launch a commercial space station with inflatable human habitats within seven years. The company's orbiting space station has no name yet. The space station is a configuration of multiple large inflatable LIFE™ habitats that can be serviced by both cargo and crew carrying Dream Chaser® spaceplanes. SNC also released that a crewed Dream Chaser will be able to shuttle private astronauts and to serve as the only vehicle capable of rescuing astronauts from space destinations and returning them to Earth via a safe and speedy runway landing.
- The two companies announced Aug. 21 that Redwire will provide a set of equipment that will be installed on a Sierra Space inflatable module known as Large Integrated Flexible Environment (LIFE). That “pathfinder” module will be launched later this decade for commercial pharmaceutical and other biotech research.
- In an interview, Mike Gold, chief growth officer of Redwire, called the agreement the first of its kind. “For the first time, a private sector company has contracted with another private sector company for substantive microgravity research and development hardware for pharmaceutical development.”

News
- NASA will partner with seven U.S. companies to meet future commercial and government needs, ultimately benefitting human spaceflight and the U.S. commercial low Earth orbit economy. Through unfunded Space Act Agreements, the second Collaborations for Commercial Space Capabilities-2 initiative (CCSC-2) is designed to advance commercial space-related efforts through NASA contributions of technical expertise, assessments, lessons learned, technologies, and data. Sierra Space is collaborating with NASA for the development of the company’s commercial low Earth orbit ecosystem, including next-generation space transportation, in-space infrastructure, and expandable and tailorable space facilities providing a human presence in low Earth orbit.
- At an investor conference in June 2023, Sierra Space was planning a launch of a standalone LIFE module as a “pathfinder” for future commercial space stations as soon as the end of 2026. That would be used, he said, for commercial pharmaceutical and other biotech research.

Space Food
In March of 2014, Veggie, a modularly designed vegetable production plant growth unit, developed and built in partnership with Sierra Space and Kennedy Space Center, was integrated by NASA aboard the International Space Station (ISS). This system provided sufficient lighting for plant growth making it possible for to successfully grow red romaine lettuce. After a safety analysis in 2015, U.S. astronauts were able to eat fresh produce for the first time on-orbit.

Additional background on Sierra Space Ghost:
- On-orbit time of five years, vehicles are outfitted with pre-determined supplies (a survival kit, inflatable boat, rations, weaponry, etc.) pre-staged on orbit.
- On call-up, the system re-orients and begins re-entry/targeting cycle; the de-orbit motor slows the vehicle to 7,000 meters per second.
- Gravity then captures the vehicle and it begins to re-enter Earth’s atmosphere with the thermal protection shield withstanding temperatures up to 2,000 degrees Fahrenheit.
- Once through atmosphere, the shield is then discarded leaving just the requested payload and a parafoil.
- At the right altitude, the parafoil is released and it steers the payload to the required area within 100 meters.
