NASA has officially abandoned the LISA project due to feasibility concerns, leading the European Space Agency (ESA) to conclude that none of the proposed mission concepts can be funded within the current schedule. Additionally, NASA has withdrawn funding from the IXO project, raising concerns about the future of X-ray telescopes. The financial strain on NASA's astronomy budget is attributed to the high costs associated with the James Webb Space Telescope (JWST). This situation highlights the challenges faced in funding significant space missions. Overall, the cancellation of these projects is seen as a setback for astronomical research.
