fly autonomously if needed. Although it could use any suitable launch vehicle, it was planned to be launched on a human-rated Atlas V N12 rocket. The vehicle will be able to return from space by gliding (typically experiencing less than 1.5 g on re-entry) and landing on any airport runway that handles commercial air traffic. Its reaction control system thrusters burned ethanol-based fuel, which is not an explosively volatile material, nor toxic like hydrazine, allowing the Dream Chaser to be handled immediately after landing, unlike the Space Shuttle. As of 2020, the Sierra Nevada Corporation says it still plans to produce a crewed version of the spacecraft within the next 5 years. The company says it "never stopped working" on the crewed version and fully intends to launch it after the cargo version, and is still committed to the crewed version as of 2021. In November 2021, Sierra Nevada Corporation reported that it received a $1.4 billion investment in Series A funding, which it will use to develop a crewed version of Dream Chaser and fly astronauts by 2025. On 25 October 2021, Blue Origin and Sierra Nevada Corporation's Sierra Space subsidiary for commercial space activities and space tourism, released their plan for a commercial space station. The station, called Orbital Reef, is intended as a "mixed-use business park". Sierra Nevada Corporation's Dream Chaser was chosen as one of the commercial spacecraft to transport commercial crew to and from the space station, along with Boeing's Starliner. CRS-2 cargo version The cargo version of the SNC Dream Chaser is called the Dream Chaser Cargo System (DCCS) and after development completes (planned for January 2023), will fly resupply flights to the ISS under NASA's Commercial Resupply Services-2 program. Featuring an expendable cargo module mounting solar panels, the spacecraft will be capable of returning to Earth while undergoing maximum re-entry forces of 1.5G. To meet CRS-2 guidelines, the cargo Dream Chaser will have folding wings and fit within a 5 m diameter payload fairing, in contrast to the Crewed Dream Chaser, which is intended to launch without a fairing. The ability to fit into a payload fairing allows the cargo version to launch on any sufficiently capable vehicle, such as Ariane 5 as well as Atlas V. An expendable cargo module will launch attached to the back of the spacecraft, expanding the cargo uplift capacity and supporting the disposal of up to of
