In the beginning of space exploration, there was sort of a Space Race between the United States and Soviets in order to achieve something bigger to dominate over one another. But after a matter of time, both the countries decided to end the competition and co-operate together for better results and the most magnificent example is the ISS.
Since, nearly all the space agencies are setting up their slingshot for Mars, I can feel a similar upcoming race or competition in the Martian Exploration e.g. Elon Musk. Are there any possible chances that all the organisations will again co-operate together to add better results in the Martian Exploration, will it be economically and scientifically better to do so?
