trash. Total uplift is planned for pressurized and unpressurized, with a downlift of contained within the spaceplane. The expendable cargo module is called "Shooting Star". On August 14, 2019, it was announced that all six Dream Chaser CRS-2 flights will be carried into orbit by ULA's Vulcan launch vehicle, with the first Dream Chaser flight being the second Vulcan flight in late 2021. However, on February 9, 2022, Ken Shields, Sierra Space's Director of Commercial Market Development announced that the first flight would be pushed to January 2023. National Security version On November 19, 2021, Sierra Space announced that it is considering a third Dream Chaser version specialized for National Security missions, though it declined to comment on what the differences compared with other versions would be. Shooting Star module In 2019, it was announced that an expendable Shooting Star cargo module would be part of the Dream Chaser cargo system for CRS-2 flights. The module is a long attachment to Dream Chaser that will allow the spacecraft to carry an additional of pressurized and unpressurized cargo to ISS. The module supports disposal of unwanted cargo by burning up upon re-entry. In addition to carrying cargo, the Shooting Star module includes solar panels that supply up to 6 kW of electrical power. It also supplies active and passive thermal management; provides Dream Chaser translation & rotation capability via six mounted thrusters; and supports berthing or docking (in different configurations) to the ISS. Access from ISS to Dream Chaser will involve crew passing through Shooting Star (which supports a shirt-sleeve environment) and through a hatch that separates Shooting Star from Dream Chaser. Sierra Nevada says the module is capable of additional types of missions in LEO or to cis-lunar destinations; they have developed a free-flying variant with additional capabilities. In July 2020, Sierra Nevada announced a contract with the Defense Innovation Unit (DIU) to use its Shooting Star expendable cargo vehicle as a possible commercial solution for a high-powered uncrewed orbital outpost. Program history The name "Dream Chaser" had been previously used for two separate space vehicle concepts. The first was planned to be an orbital vehicle based on the HL-20, with the second suborbital vehicle proposed by the Benson Space Company for the purposes of space tourism. The Dream Chaser was publicly announced on September 20, 2004. In April 2007, SpaceDev announced that it had partnered with the United Launch
