Space selfie  A space selfie is a selfie (self-portrait photograph typically posted on social media sites) that is taken in space. This include selfies taken by astronauts (also known as astronaut selfies), machines (also known as space robot selfies and rover selfies) and by an indirect method. 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. The extra-vehicular activity (EVA) equipment used by astronauts during spacewalks contains a specially designed camera for photography in outer space. The main purpose of the EVA camera is to take pictures of the subjects related to the missions. There have been many space selfies, some of which use the visor of another astronaut's helmet as the mirror. Early space selfies after the word "selfie" was first used in 2002 without assistance from another astronaut included Donald Pettit and Stephen Robinson. Pettit took one during the Expedition 6 in January 2003. Robinson took his during the repair of the Space Shuttle Discovery on August 3, 2005, as part of the STS-114 mission. Another notable space selfie was taken by Japanese astronaut Akihiko Hoshide during the six-hour, 28-minute spacewalk on September 5, 2012. Hoshide's photo became a viral phenomenon after Commander Chris Hadfield uploaded the photo to his Twitter account on September 30, 2013. Coincidentally, Oxford University Press, the publisher of the "Oxford English Dictionary", announced in November 2013 that "selfie" was the word of the year for 2013. The picture topped many selfie lists of the year. Another space selfie of Hoshide also showed up on Instagram and appeared on a list of top selfies of 2013. Space selfies can be dated back to 1976 when the lander of the Viking 2 mission took the photo of its deck after landing on Mars; however they were not considered by Discovery News as true selfies in its list of top 10 space robot selfies. In 1989 the Galileo spacecraft took a selfie using its near-infrared mapping spectrometer (NIMS). The image was taken in order to judge how parts of the spacecraft would block the instrument's view. The resulting image was fuzzy and warped by Galileo's spin. An unusual approach was taken in 2010 by IKAROS, launched by Japan Aerospace Exploration Agency (JAXA) it included two wireless cameras that were ejected out of the spacecraft for the sole purpose of taking "hand free" space selfies.
