I am home to millions of different forms of life including bacteria, animals, plants and you humans. At present I am the only place in the Universe where any kind of life, simple or complex, is known to exist. About 71% of my surface is covered with water, giving me my characteristic blue appearance from space. This presence and abundance of liquid water makes me unique compared to my planetary neighbors. Liquid water is a fundamental element for life. as we know it, to exist.
On March 2, 2019, I was placed on board the SpaceX Crew Dragon and launched to the international Space Station as a "super hi-tech zero gravity indicator." I was supposed to go back home the next week, but the astronauts loved me so much that I was invited to stay on board!
