Pale Blue Dot, Earthrise, The Blue Marble, The Day the Earth Smiled, Family Portrait and more… Less than half a century, The Human Space Race is reached a meritorious place which no one could dream. From Sputnik to First Man on Moon, Mariner to Voyager Missions, Mars to Trans-Neptunian planets, humanity’s horizon and knowledge about Universe and our Solar System has evolved in an unimaginable way.
Since Mid-19’s (when Sputnik was launched and Gagarin become firs man in space), our research and activities in space have greatly increased. As humanity’s curiosity about space and the universe increased, more probes have been sent and more planets are visited. As a result, hundreds of precious unmanned space missions were carried out.
Some of the missions that got out of these hundreds of and some prominent events in these missions have become milestones of humanity’s space adventure. In this article, I wrote these prominent milestones that important, for the history of Humans from Earth.

The first known space selfie (during an EVA – an earlier shot inside the capsule was taken on Gemini 10 by Michael Collins) was taken by Buzz Aldrin during the Gemini 12 mission:
Curiosity, which landed on Mars in 2012, was equipped with the Mars Hand Lens Imager (MAHLI) camera. It can maneuver its robotic arm and turn the attached camera around to take its head shots. Discovery News described the maneuver as the way to take a truly authentic selfie and gave it the title King of Selfies in 2013. The first space selfie on another planet was taken by the Curiosity rover.
