See you tomorrow on Mars!

NASA claims that it will be possible to set foot on Mars in 2030. And with good reason: in July 2020, no less than three rockets set off for Mars in ten days. The first carried the UAE probe Al-Amal (Hope), the second the Chinese robot Zhurong and the third the American robot Perseverance. These three launches illustrate the renewed interest in the conquest of space. But who will arrive first? And with what ambitions?
Although international space law has been under construction since the 1960s, it is still in its infancy and not very binding. In addition to scientific progress and the technological advances that flow from it, the conquest of space is also a matter of international stature, which sharpens the competition between the powers. But the entry of new private players (such as the American SpaceX or the Chinese OneSpace) is changing the situation. Where do we place the cursor between cooperation and international competition? Behind a project for humanity, what are the hidden ambitions of the conquest of space?
