Elon Musk, the founder of the American company SpaceX, said that a group of people will likely die in the early stages of exploring Mars. That transporting people to Mars would be dangerous, but necessary to ensure the survival of mankind.
And according to RT, Musk said, it's like going to Mars, explorer Ernest Shackleton going to the South Pole. You may die ... and you may not get good food and all these things. It is a dangerous and arduous journey from which you may not return alive, but it is a glorious adventure.
And about receiving many requests to participate in the trip to Mars, Musk said: Explorers must be careful about what they desire. Frankly, a group of people might die at first, so we only want volunteers to go on the trip.
