The timeline for sending humans to Mars is a subject of ongoing research, planning, and speculation among space agencies and private companies. As of now, there is no definitive date for a crewed mission to Mars, but several organizations have expressed ambitions to make it happen within the next couple of decades.
SpaceX, led by Elon Musk, has been particularly vocal about its plans to send humans to Mars. Musk has stated his goal of establishing a self-sustaining human settlement on Mars, with the first crewed mission potentially happening in the mid to late 2020s, although timelines in space exploration often face delays and uncertainties.
