Space Day takes place on May 01, 2015. Space Day is an educational event held on the first Friday in May. It's goal is "to promote math, science, technology and engineering education by nurturing young peoples' enthusiasm for the wonders of the universe and inspiring them to continue the stellar work of today's space explorers" (according to spaceday.org). Space Day was created by Lockheed Martin Corporation in 1997.
Space or outer space describes the vast empty regions between planets and stars. The study of these, and other, astronomical objects is called astronomy, one of the oldest sciences. It is often said that space exploration began with the launch of Sputnik 1, the first man-made object to orbit the Earth. Then, in an almost unbelievable feat of human achievement, in 1969 Neil Armstrong and Buzz Aldrin travelled to the Moon and set foot on the surface during the Apollo 11 mission.
Recently, it has become clear that the possibility of space colonization may no longer be exclusively reserved for science-fiction stories, and many controversial issues surrounding space have come to light, including commercial spaceflight, space laws and space weapons.
