Colonizing Mars
Many movies are centered around the plot of a parallel universe - a place that is similar to but not quite Earth. This encapsulates the possibilities of Mars, a place that humans have looked up at in the sky since ancient times. The dream of a human stepping foot on Mars is closer than ever to becoming reality, particularly because of the contributions of SpaceX and its founder Elon Musk.
Major steps have been taken by SpaceX to achieve this goal, with none being bigger than the development of the Starship rocket. It is being designed to carry up to 100 passengers to Mars and is currently in the prototype stage. Another major part of the equation is cost, and SpaceX has got that covered with their Falcon 9 and Falcon Heavy rockets which have shown to be able to successfully land and be reusable. This can reduce the cost of space travel and increase the likelihood of potential frequent Martian travel.
Logically, the next question asked would be how would we sustain life on Mars? SpaceX has developed the Raptor engines, which can be produced on Mars using insitu resource utilization(ISRU), allowing for fuel production on Mars. The Raptor engines use methane and liquid oxygen as fuel. In order to support humans that have reached Mars, SpaceX plans to send multiple cargo missions to Mars carrying essential supplies and technology to sustain life on the planet. Furthermore, Musk has created an initial plan for a Mars base, in which he envisions small settlements that are built during early missions that include food production systems, water, and power.
