The Mars rover named Curiosity has been rolling on the planet since 2012 and has traversed more than 14 miles. On its way to Mars right now is another rover named Perseverance that will explore the Martian terrain, take thousands of pictures and sample the soil.  

Will humans ever follow in their tire tracks? The task is daunting and would be like no adventure before it.    

Travel time from Earth to Mars is roughly six months. Once a crew reaches Mars, they must remain on the surface until the Earth orbits into closer alignment. That takes another 14 months. They would then make the six-month flight back to Earth. All in all, going to Mars and back would take more than two years and
