What commenters say

• The cancellation of the Mars Sample Return mission is a significant blow to NASA's plans for Mars exploration.
• The US is falling behind in space exploration due to a lack of funding and vision.
• China's success in space exploration is not solely due to US decline, but also a result of their own investments and efforts.
• The rise of China's space program is a natural consequence of the US's decreased focus on space exploration.
• The Mars Sample Return mission was poorly designed and would have required significant additional funding to complete.
• The US's decline in space exploration is a result of a shift in priorities and a lack of political will to invest in science and technology.
• The comparison between US and Chinese space programs is not necessarily a zero-sum game, and both countries can make significant contributions to space exploration.
• The cancellation of the Mars Sample Return mission is not a surprise given the program's long-standing issues and funding challenges.
