Sierra Space's Dream Chaser space plane, Tenacity, is set to embark on its inaugural mission to the International Space Station (ISS) after undergoing extensive testing and development. The spacecraft is being prepared for launch aboard a United Launch Alliance Vulcan Centaur rocket from the Cape Canaveral Space Force Station in Florida, and it aims to conduct seven cargo missions to the ISS as part of NASA's strategy to diversify commercial resupply services for the space station. The Dream Chaser is designed to be highly reusable, reliable, and capable of returning to Earth with significant research samples and equipment. Sierra Space's dedication to overcoming challenges in constructing Tenacity, its focus on sustainability, and its commitment to contributing to space science and the commercial space economy are evident in the craft's development and upcoming mission.
