Elon Musk's idea of a mission to Mars will eventually work. His straightforward representation that the mission risks entail the strong possibility of death will deter few with similar dreams and aspirations. His ideas regarding the mission to Mars will work eventually, if not in this century then in the next century.
Yes, Elon Musk's idea will work because he has not been proven wrong yet. All of his ideas have led to wonderful inventions and going to Mars will be similar. Once a team of scientists is willing to travel that far into outer space, Musk will prove he was right.
SpaceX is using a new Raptor engine for Mars travel, which performs the final landing burn, and the ship can withstand the heating. The ship uses the PICA-family of heat shield materials used on the company’s Dragon spacecraft. Mars is nearly 225 million km from Earth and the journey to the planet will take six to nine months.
Elon Musk has grand visions of a mission to Mars. However, these visions need a prescription adjustment. The current status of space technology is simply not advanced enough to support such a massive undertaking. There is much more progress to be made in that area before people can start calling Mars home.
