Now : Human Exploration of Mars Could Be Reality
Figuring out what kind of material and environment on Mars , scientists rely on robots and monitoring from space . When will astronauts could actually set foot on the red planet ?
Launched Space , the search is done by robots and survey orbit reveal the presence of water on the surface of Mars . This is good news for the human exploration missions on the dusty planet .
One obstacle is the distance of Mars is far away , so the spacecraft could only deliver transporting astronauts to arrive at Mars . Scientists think how to create a more powerful fuel to bring the astronauts back to Earth .
Propulsion system ( activator ) for human trip to Mars and back to Earth will use the Nuclear Thermal Propulsion chemical or machine . Fuel to support both of them can be created by involving liquid hydrogen .
Producing the fuel can be taken from the water found on Mars . Moreover , the reaction of hydrogen with carbon dioxide found in the atmosphere of Mars will also create methane substances , or other chemical fuel engines are beneficial .
