In 2016, NASA awarded a Commercial Resupply Services-2 contract to Sierra Space, formerly part of Sierra Nevada Corporation, to resupply the International Space Station with its Dream Chaser spaceplane and companion Shooting Star cargo module. As part of its contract, Sierra Space was awarded a minimum seven flights, and the agency previously issued firm-fixed price task orders for four Dream Chaser resupply missions based on the needs of the space station.<\/p>\n

After a thorough evaluation, NASA and Sierra Space have mutually agreed to modify the contract as the company determined Dream Chaser development is best served by a free flight demonstration, targeted in late 2026. Sierra Space will continue providing insight to NASA into the development of Dream Chaser, including through the flight demonstration. NASA will provide minimal support through the remainder of the development and the flight demonstration. As part of the modification, NASA is no longer obligated for a specific number of resupply missions, however, the agency may order Dream Chaser resupply flights to the space station from Sierra Space following a successful free flight as part of its current contract. <\/p>\n

\u201cDevelopment of new space transportation systems is difficult and can take longer than what\u2019s originally planned.  The ability to perform a flight demonstration can be a key enabler in a spacecraft\u2019s development and readiness, as well as offering greater flexibility for NASA and Sierra Space,\u201d said Dana Weigel, manager of NASA\u2019s International Space Station Program. \u201cAs NASA and its partners look toward space station deorbit in 2030, this mutually agreed to decision enables testing and verification to continue on Dream Chaser, as well as demonstrating the capabilities of the spaceplane for future resupply missions in low Earth orbit.\u201d<\/p>\n

NASA, and its commercial and international partners, will continue to supply the orbital complex with critical science, supplies, and hardware as the agency prepares to transition to commercial space stations in low Earth orbit.   NASA continues to work with a variety of private companies to develop a competitive, space industrial base for cargo services, which will be needed for future commercial space stations. With a strong economy in low Earth orbit, NASA will be one of many customers of private industry as the agency explores the Moon under the Artemis campaign and Mars along with commercial and international partners.<\/p>\n","protected":false},"excerpt":{"rendered":"
