    Photographic self-portraits have existed for as long as cameras have been in human hands. But what about selfies in space? On Twitter last year, NASA astronaut Edwin Aldrin, who famously became the second man to walk on the moon in July 1969, laid claim to a spaceflight first: taking the first selfie in space during the Gemini XII mission in 1966.

“For me, it needs to be digital to be selfie,” argues Jennifer Levasseur, a director at the Smithsonian National Air and Space Museum. According to Levasseur, the concept of a selfie is directly linked to internet culture. “The thing that makes a selfie is sharing it,” she says.

Still, astronauts have been carrying cameras aboard space vehicles since the 1960s. In 1966, Aldrin used a Hasselblad camera designed specifically for space. Hasselblad also painted the first camera in space a matte(磨砂) black to reduce reflections in the orbiter window. But cameras used in space need to survive extreme conditions, like temperature swings from -149° to 248°F, so Hasselblad painted later model silver.

Astronauts visiting the moon then had to take out the film and leave their camera bodies behind when they returned to Earth, because early space missions were limited by a weight limit on the returned trip. Then a big change in space camera technology came after the space shuttle Columbia broke apart on its return to Earth in 2003, Levasseur notes. “Fear that they’d never be able to bring film back from space and lose all that hard work accelerated the push for digital,” she says.

Today, astronauts also have access to internet and social platforms in space and can post true space selfies made using digital cameras. Similarly, space robots are participating in selfie culture, capturing remote pictures of themselves in space or on other planets and sending them back to Earth.
