Group 1 - The U.S. House Appropriations Committee has proposed a funding bill for fiscal year 2026 that supports the termination of NASA's "Mars Sample Return" mission [1] - The bill reallocates $110 million to a project called "Mars Future Missions," aimed at continuing the technological development related to the "Mars Sample Return" mission [1] - NASA's science budget for fiscal year 2026 is set at $7.25 billion, reflecting a 1% decrease from the previous year, but is significantly higher than the White House's earlier proposal to cut the budget by half [1] Group 2 - There has been a long-standing divide among U.S. planetary scientists regarding the "Mars Sample Return" mission, with concerns about its high budget potentially consuming too much research funding [2] - An independent review committee's assessment indicated that the total budget for the project could reach $11 billion, although NASA later proposed to reduce it to $7 billion [2] - Terminating the "Mars Sample Return" mission would leave a significant research goal for U.S. planetary scientists in a state of uncertainty, potentially jeopardizing the country's leadership in Mars exploration [2]
