“I think many in the space community believe NASA’s planning for a set of missions to ultimately get us to Mars has become more coherent and consolidated.” Even though the costs of a such mission remain enormous, the enthusiasm among the American public for a human mission to Mars is considered a helping aspect. A decade ago, a myth was born, sustaining that sending astronauts to Mars will cost a $1 trillion. In fact, now is accepted that a small fraction of the cost of developing and flying the F-35 fighter jet will cover a such mission but twenty years of preparation and $100 billion will be needed. The mission could be funded out of the current NASA budget, even with contributions from other countries. “It’s feasible, it’s affordable, and it can be done without impacting the federal budget or the NASA budget,” said Chris Carberry, executive director of the nonprofit ExploreMars group, organizers of the conference. The Mars program will take advantage of technology improvements and lessons learned from the International Space Station and other space missions.
