美國宇航局面臨巨額預算削減。川普與馬斯克的爭執加劇了不確定性

NASA is currently facing significant budget cuts that threaten the future of many space missions and projects. The situation has become even more complicated due to a public disagreement between US President Donald Trump and Elon Musk, the CEO of SpaceX. SpaceX plays a crucial role in NASA's operations by providing rockets that resupply the International Space Station and are expected to help send astronauts to the Moon and Mars in the future. However, the White House has proposed large reductions in NASA's funding, especially for science projects, which could be cut by nearly half. This has raised concerns about the impact on ongoing and planned missions.

The proposed budget cuts could lead to the cancellation of around 40 science missions that are either in development or already in space. These missions include important projects to study Mars, Venus, and Earth's environment. For example, NASA's Mars Sample Return mission, which aims to bring rocks from Mars back to Earth, and the European Space Agency's Rosalind Franklin rover mission to Mars, are both at risk. Additionally, many Earth observation programs that monitor climate change could be shut down, which worries scientists because these programs provide vital information about our planet's health. NASA plans to focus more on sending astronauts to the Moon and Mars, but this shift means less funding for other scientific research.

Experts warn that these budget cuts could have a chilling effect on NASA's long-term goals. Space exploration requires careful planning and cooperation between government agencies, private companies, and academic institutions. The conflict between President Trump and Elon Musk adds uncertainty to this process. NASA's current rocket, the Space Launch System, has faced delays and high costs, with each launch costing over $4 billion. In contrast, private companies like SpaceX and Blue Origin are developing more affordable rockets, but these are still being tested and have not yet proven fully reliable. If these companies require additional funding to complete their projects, Congress may need to provide it, which could create further budget challenges. The future of NASA's missions and the US space program depends heavily on how these budget issues are resolved.
