What Are Some Reasons Against Space Exploration?

Some criticisms of space exploration include that it wastes taxpayer money, which could be used to address problems on Earth such as climate change and poverty. Additionally, most of NASA's space exploration programs are unsuccessful. ScienceDaily notes that space exploration is used as a tool for geopolitical and military rivalry and does not improve societies. The Congressional Budget Office cites safety concern as the main argument against space exploration.

According to Aljazeera, space exploration is not a worthwhile endeavor because the Earth is not yet fully exploited. Additionally, space exploration programs are criticised for being too ambitious in their space settlement goals. Critics of space exploration oppose its commercialization and a shift from the original goals of advancing scientific research, protecting the survival of humanity and uniting nations.

Satellite communication and space tourism are examples of commercial activities in space exploration. The Congressional Budget Office argues that NASA should limit its space exploration activities to those that support necessary space communication processes. Furthermore, the robotic missions of space programs are limiting.

BBC News argues that there is adequate understanding of the Earth's surroundings, making it unnecessary to prioritize space exploration programs. However, Wikipedia notes that over 71 percent of U.S. citizens support space exploration. This is because many resources on Earth are being depleted. Current space exploration programs are primarily focused on Mars and the moon, considering whether or not humans could utilize them or materials found on them to sustain life.
