SpaceX boss Elon Musk has taken a decisive step closer to his dream of sending a manned mission to Mars by the end of this decade with the first controlled landing of his ‘Starship’. However, there is still one crucial hurdle to overcome: human biology.
With an average distance of about 140 million miles, Mars is one of Earth’s closest habitable neighbors, according to SpaceX. The planet is “half as far from the sun as Earth, so it is still well illuminated by the sun. He’s a little cold, but we can warm him up. The atmosphere is mainly CO2 with some nitrogen and argon and some other trace elements, meaning we can grow plants on Mars by compressing the atmosphere. The gravity on Mars is about 38 percent of that on Earth, allowing you to lift heavy objects and jump around. “In addition, the day is surprisingly close to that of Earth,” the space company explains on its website.
There are many obstacles to overcome
In 2029 – previously 2025 was discussed – SpaceX wants to send its first manned mission on a six-month journey to Mars. By 2050, a million people will be transported to the Red Planet – at least that is the vision of company founder Elon Musk, who dreams of a ‘multiplanetary society’. He couldn’t imagine anything more exciting than going out and being among the stars, the second richest person on earth, with an estimated fortune of $195 billion, enthuses.
However, there are still many obstacles to overcome on the way to Mars, and these are not only technical or logistical, but also biological.
