An astronaut has never been to space for 3 years so they will miss their children and family. We want to be sure they don’t get sad, depressed and make mistakes with their work. We will let them 3D print the “actual” hand of their child or family members. This will allow the astronaut to feel connected to their family. If the astronaut is a parent they can reprint the hand as the child grows, maybe every 6 months or year. I think this will help the astronaut be more happy and do better work. This will help NASA by having better, healthier workers. We need happiness so the astronauts don’t fail. Go TEAM NASA!
