“The United States is justified in spending billions of dollars on NASA space missions to Mars.”

Throughout the course of history, man has dreamed of stepping foot on another planet. The advances in technology in the 20th century have allowed man to do what at one time was considered unthinkable for millenniums before. With the advent of the modern space program in the early 1950’s, NASA has performed many inconceivable feats. They have sent and returned men to space. They’ve set up space stations orbiting the earth. They have allowed men to land on the moon, collect samples, and then return to the earth. They have sent spacecraft to explore comets and other planets. They have even sent space probes outside the known walls of this solar

Perhaps this can lead us to understand how life will one day disappear from our planet, or even maybe, prevent that from occurring.

Many critics have pointed to recent failures from NASA space missions to the planet Mars as reasons to abandon attempts to further send space probes. These missions cost millions of dollars, and they resulted in disaster. For instance, one spacecraft was sent to land on Mars, and, as it approached the planet after its six-month trip through space, was suddenly unreachable. After a commission was formed to study what went wrong, they discovered that some engineers forgot to convert some measurements from English standard to metric rule. This little error was overlooked by hundreds of engineers and physicists. This resulted in a
