The idea of sending humans to Mars is often framed as a question of ambition or funding.
In reality, future missions to Mars are a logistics problem shaped by physics. Distance, energy, time and mass define what is possible long before politics or budgets enter the equation. Mars sits, on average, about 225 million kilometres from Earth. That number alone doesn’t explain the difficulty. What matters is how you move people and equipment across that distance, how long it takes, and how much you have to carry to survive the journey.
