I am Amir Raja, a doctor from Kuala Lumpur, Malaysia. It would be very important to have a doctor along on the first manned mission to Mars because you would need someone to help you when you have an injury or if we encounter any foreign diseases. I am excited for this trip because it would be exciting to start a foothold for humanity, on mars.
