NASA is planning on sending humans to Mars in just 15 years. And unlike the space agency’s moon missions, NASA’s new class of astronauts who hope to land on the red planet is 50 per cent female .Among the hopefuls are Nicole Aunapu Mann, Anne McClain, Jessica Meir, and Christina Hammock Koch – four female pioneers who are changing the face of the space industry. Mars is the next big goal, not just for NASA and private groups such as Space X, but also for the likes of Russia, China and Europe. It will be the farthest and most ambition manned space mission in history. Getting there will take six to nine month, while a round-trip will take two to three years.
