We have seen in the past that two competing spacefaring nations (the United States and Russia) could maintain ties and mutualize their knowledge and resources to achieve a common goal in space exploration (i.e the International Space Station) (https://www.nature.com/news/build-on-the-outer-space-treaty-1.22789). However, we have recently witnessed a setback from the United States in their will to cooperate with other nations, on matters such as commerce in space and new exploration goals. Their recent decisions, such as banning their scientists to share information with Chinese officials and scientists (https://www.theguardian.com/science/2016/aug/28/china-new-space-superpower-lunar-mars-missions) and the Space Act voted in 2015 that unilaterally allows US citizens and companies to extract and sell extracted minerals from space, could maybe be part of their new Space strategy. With the ISS mission ending in 2020, should we be concerned by the recent American behavior regarding space exploration?
