#Throwback to 1969, when Astronaut Edwin E. Aldrin Jr. descends the steps of the Lunar Module's ladder as he prepares to walk on the Moon. Wednesday is International #MoonDay, marking 53 years since astronauts landed on the moon for the first time. Space science and technology and their applications are increasingly being used to support a wide range of #UnitedNations activities. The unoosa works to promote international cooperation in the peaceful use and exploration of space, and in the utilisation of space science and technology for sustainable economic and social development. 📷: UN Photo/nasa #globalgaols
