Sierra Nevada Corporation’s Dream Chaser completed an important step toward orbital flight with a successful captive carry test at NASA’s Armstrong Flight Research Center in California, located on Edwards Air Force Base. A helicopter successfully carried a Dream Chaser test article, which has the same specifications as a flight-ready spacecraft, to the same altitude and flight conditions of an upcoming free flight test. The Dream Chaser is a lifting-body, winged spacecraft that will fly back to Earth in a manner similar to NASA’s space shuttles. The successful captive carry test clears the way for a free flight test of the spacecraft later this year in which the uncrewed Dream Chaser will be released to glide on its own and land.

STS068-267-097 (30 September-11 October 1994) --- An extensive view eastward from the irrigated San Joaquin Valley in the foreground, across the Sierra Nevada (living up to its name in early October), into the desert of eastern California and Nevada (which has no snow, despite the name). Mono Lake is just visible at the left edge of the frame; Owens Valley extends southward to Owens Lake, the next valley is Panamint Valley, and then Death Valley. Las Vegas and Lake Mead are visible at the upper right of the frame. The Space Radar Laboratory 2 (SRL-2) obtained extensive, multiple-pass data from many test sites within the region displayed, including Mammoth Mountain ski area south of Mono Lake, and in Death Valley.
STS058-72-004 (18 Oct-1 Nov 1993) --- The Sierra Nevada Mountain Range can be seen in this north-looking high oblique view taken in October, 1993, by the STS-58 crew. Visible in the view to the west of the Sierra Nevada are the San Joaquin and Sacramento Valleys of central California. The San Francisco/Oakland Bay Area can be seen to the west of the valley at the extreme left of the photograph. To the east or right of the Sierra Nevada, the basin and Range Region of central and northern Nevada is visible. Mono Lake, Lake Tahoe and Pyramid Lake are also visible in this scene. The long northwest/southeast trending Walker Lane Shear Zone, which lies just to the east (right) of the Sierra Nevada is also visible. Near the top of the view (near the horizon), the snow covered volcanic peak Mount Shasta can be seen. Over 645 kilometers (400 miles) long and from 65 to 130 kilometers (40 to 80 miles) wide, the Sierra Nevada have many peaks in excess of 3,300 meters (11,000 feet) above sea level. A titled fault block in structure (the largest in the United States) and shaped by glaciers during the last ice age over 12,000 years ago, the Sierra Nevada eastern front rises sharply from the Great Basin of Nevada, while its western slope descends gradually to the hills bordering the Central Valley of California. Snow-fed streams supply much of the irrigation water to the Central Valley and to western Nevada and also generate hydroelectricity. Recent above normal precipitation (snowfall) of the last two years has helped in alleviating the drought conditions that had prevailed throughout most of California in the mid and late 1980's and early 1990's.

CAPE CANAVERAL, Fla. -- This is an artist's conception of Sierra Nevada Corp. SNC Space System's Dream Chaser spacecraft atop a United Launch Alliance ULA Atlas V rocket under development for NASA's Commercial Crew Program, or CCP. The integrated system was selected for CCP's Commercial Crew Integrated Capability, or CCiCap, initiative to propel America's next human space transportation system to low Earth orbit forward. Operating under a funded Space Act Agreement, or SAA, SNC will spend the next 21 months completing its design, conducting critical risk reduction testing on its spacecraft and launch vehicle, and showcasing how it would operate and manage missions from launch through orbit and landing, setting the stage for a future demonstration mission. To learn more about CCP, which is based at NASA's Kennedy Space Center in Florida and supported by NASA's Johnson Space Center in Houston, visit www.nasa.gov/commercialcrew. Image credit: SNC
STS059-L09-162 (9-20 April 1994) --- Orient with the snow-covered mountains (Sierra Nevada of California) in the upper right corner. Then Owens Valley runs along the top of the photograph to Owens Lake playa at top center. The upper end of Death Valley extends from right to left in the foreground, with the drainage running down to a playa at Stovepipe Wells in the left foreground. Geologists are studying microwave signatures of the different playa surfaces, and the coatings on alluvial fans that extend from mountain masses, to try to sort out the history of different climates in this formerly wet but now hyperarid region.

The cargo logistics module for Sierra Nevada Corporation’s Dream Chaser, the company’s reusable spaceplane, arrives at the Space Station Processing Facility high bay at NASA’s Kennedy Space Center in Florida on Aug. 27, 2019. The cargo module – a 15-foot attachment to Dream Chaser – provides extra storage for payloads and provides cargo disposal upon re-entry into Earth’s atmosphere. Dream Chaser will deliver more than 12,000 pounds of cargo to the International Space Station under the agency’s Commercial Resupply Services 2 contract. The spacecraft and cargo module will begin resupply and return services missions to the space station in late 2021.
Sierra Nevada Corporation’s (SNC) Dream Chaser pressure test article is moved into the low bay of the Space Station Processing Facility at NASA’s Kennedy Space Center in Florida on June 3, 2020. The test article was shipped from Louisville, Colorado. It is similar to the actual pressurized cabin being used in the Dream Chaser spaceplane for Commercial Resupply Services-2 (CRS-2) missions.

Dream Chaser will deliver more than 12,000 pounds of cargo to the International Space Station under the agency’s Commercial Resupply Services 2 contract. The spacecraft and cargo module will begin resupply and return services missions to the space station in late 2021.

Sierra Nevada Corporation’s (SNC) Dream Chaser pressure test article arrives by flatbed truck at NASA’s Kennedy Space Center in Florida on June 3, 2020, from Louisville, Colorado. It will be transported to the high bay in the Space Station Processing Facility. The test article is similar to the actual pressurized cabin being used in the Dream Chaser spaceplane for Commercial Resupply Services-2 (CRS-2) missions. NASA selected Dream Chaser to provide cargo delivery, return and disposal service for the International Space Station under the CRS-2 contract. The test article will remain at Kennedy while SNC engineers use it to develop and verify refurbishment operations that will be used on Dream Chaser between flights.

The DC-8 in flight near Lone Pine, Calif. In the foreground are the Sierra Nevada Mountains, covered with winter snow. In the distance are the White Mountains. The DC-8's fuselage is painted white with a dark blue stripe down the side. The wings are silver, while the engine pods are white. In this view of the airplane's right-hand side, only a few of its antennas are visible. The experimental payload can be as great as 30,000 pounds of equipment for gathering data of various sorts.
Sierra Nevada Corporation’s Dream Chaser spacecraft arrives by truck at NASA’s Armstrong Flight Research Center in California, located on Edwards Air Force Base. The spacecraft will undergo several months of testing in preparation for its approach and landing flight on the base’s 22L runway. The test series is part of a developmental space act agreement SNC has with NASA’s Commercial Crew Program and will help SNC validate aerodynamic properties, flight software and control system performance. The Dream Chaser is also being prepared to deliver cargo to the International Space Station under NASA’s Commercial Resupply Services 2 contract beginning in 2019. The cargo Dream Chaser will fly at least six delivery missions to and from the space station by 2024.
