There aren't many people who can claim the dreams they had in early childhood shaped the course of their entire life، as the Daily Mail said. But for one American teenager، Alyssa Carson، seeing images of spacefaring cartoon characters on television prompted a lifelong obsession. Aged three years-old، she told her father 'Daddy، I want to be an astronaut، and be one of the people that go to Mars'. Since then، she has made it her life's work to make her childhood dream a reality. In the year 2033 – when Mr Carson will be 32 – she plans to soar off to the red planet، where she will help a Martian colony thrive. The 17-year-old girl، from Hammond، Louisiana، has been obsessed with space from the moment she watched the cartoon The Backyardigans، in which five animal friends go on imaginary adventures in their backyard، including a mission to Mars. This plotline became the birth of a lifelong quest to realise her dream. Ms Carson spreads her message to her hundreds of thousands of followers across her various social media accounts and blog. She also attends seminars and other public speaking events to address her peers and encourages other youngsters - particularly women - to get involved in science، technology، engineering and maths. Speaking to Teen Vogue، she said: 'I did the same thing as other kids، like switching my mind about careers، wanting to be a teacher or the president one day. 'But the way I always thought about it was I would become an astronaut، go to Mars، come back، and then be a teacher or the president.'
