Further an unimaginable achievement came that is in 1969 Neil Armstrong and Buzz Aldrin travelled to the Moon and set the foot on its surface during the Apollo 11 mission.
National Space Day aims to promote math, science, technology, engineering education in young people to inspire and motivate them to pursue a career in science especially space. This day is dedicated to those who have made an extraordinary achievements, benefits and opportunities in the exploration and use of space.
National Space Day: History
Space Day was created in 1997 by the Lockheed Martin Corporation as a one day event to observe several wonders of the unknown space where planets, stars floats and also to encourage children to have more interest in the subject science.

- There are mountains on the planet Pluto.
- Let us tell you that on mars the sunset appears blue.
