What's Happening?
Sierra Space's Dream Chaser space plane, designed to deliver cargo to the International Space Station, remains in final assembly and testing phases. Despite being under development for over two decades, a definitive launch date has not been set. NASA's program manager for the International Space Station, Dana Weigel, stated that the agency is prepared for the launch once Sierra Space completes necessary certifications. The focus is currently on software and propulsion system certifications, following lessons learned from previous spacecraft issues, such as Boeing's Starliner. The Dream Chaser is powered by small rocket engines using kerosene and hydrogen peroxide propellants, requiring thorough testing before its maiden flight.

Why It's Important?
The successful launch of Dream Chaser is crucial for Sierra Space and NASA's cargo delivery missions to the International Space Station. The space plane's development represents significant advancements in spacecraft technology, particularly in propulsion systems that use less toxic propellants. Delays in its launch could impact NASA's logistics and supply chain for the space station, affecting scientific research and operations. The project also holds potential for future commercial spaceflight endeavors, contributing to the growing space industry and innovation in spacecraft design.
What's Next?
Sierra Space must complete the final certification processes for Dream Chaser's software and propulsion systems before proceeding with the launch. NASA's requirement for end-to-end testing of flight software aims to ensure reliability and safety, preventing issues experienced in past missions. Once certified, Dream Chaser will be scheduled for its first flight to the International Space Station, marking a significant milestone in Sierra Space's contract with NASA. The outcome of these tests will determine the timeline for the space plane's operational deployment.
