The ongoing dispute between Donald Trump and Elon Musk over a major spending bill is significantly impacting Nasa, leading to potential deep cuts in its budget and uncertainty about future programs.

• Nasa's budget request includes a nearly **50%** cut in funding for science projects, threatening **40** missions related to climate change and planetary exploration.
• Key figures include Dr. Simeon Barber from the Open University, who noted a “chilling impact” on the space program.
• The proposed budget also threatens critical international collaborations, such as the return of martian rock samples and the European Space Agency's plans for the Rosalind Franklin Rover.
