Mars is the focus of much scientific study about possible human colonization Mars and past presence of water ice make it arguably a feasible endeavor. The surface conditions of.
The successor to the Space Shuttle could be ready for liftoff as early as 2018. When it does take off, NASA's Space Launch System will be able to carry 70 metric tons of supplies into orbit. Later, it could send payloads of up to 130 metric tons into a trajectory towards Mars. At 382 feet tall, the SLS will eventually be the largest launch vehicle ever built, and even more powerful than the Saturn V rockets that carried the Apollo astronauts to the Moon. "This payload capacity far exceeds the capability of current and planned commercial launch vehicles," says the report. Along with the Orion crew capsule (also in development at NASA), the SLS could eventually carry astronauts to Mars and other deep space destinations.
The SLS is powered by the combustion of liquid hydrogen and liquid oxygen. But SLS is only meant to carry astronauts out of Earth orbit. For the approximately 7-month journey to Mars, using rocket fuel to propel a spacecraft requires a large gas tank that would be very expensive to launch off the ground. Instead, NASA might use the power of the Sun to send cargo, supplies, and maybe even astronauts to Mars.
Developing these technologies won't be easy. It's going to take many years and billions of dollars, and some experts are skeptical that NASA can make it happen. There are plenty of challenges to overcome on the “Journey to Mars”, not the least of which is NASA's flat lining budget. But going to Mars would be pretty sweet.
